The newest installment of the Creative Cartography exhibit series is now on view at the Map and Geospatial Hub. This year’s art exhibit, Place and Space, features artwork from Prof. Ellen Meissinger's Fall 2018 Art on Paper class.
Place and Space is the product of a five-year collaboration between the ASU Library Map and Geospatial Hub and the Herberger Institute for Design and the Arts. School of Art students take maps that have been withdrawn from the library's collection and create unique and innovative artwork with them. Twenty-three pieces are on display through November 26.
To celebrate the fifth exhibit, the Map and Geospatial Hub will be hosting an opening reception on Thursday, Nov. 8, 4:00-6:00 p.m. All are welcome.
ASU Now recently featured an article on the exhibit describing the collaboration in more detail. Read more here.
ASU is starting an on-campus chapter of YouthMappers! We will be creating maps that will help the United States Agency for International Development (USAID) projects focus on increasing food security, preventing diseases such as malaria, and responding to natural disasters in Asia, Africa, the Middle East, Eastern Europe, Latin America, and the Caribbean.
Help make the world a better place by mapping it!
When: Thursday November 8, 2-7pm.
Where: Student Pavilion, Room 324
What to Bring: We will have computer access, but we encourage you to bring your laptop (and a mouse helps too).
Come and go through the afternoon to hear about YouthMappers, learn to edit OpenStreetMap for a real humanitarian project, socialize and eat pizza, and be a part of global mapping community. Your contribution will make a difference.
Geocoding is the process of assigning a geographic coordinates to a description of location-related information. The most common use is the attribution of geographic coordinates (latitude and longitude) to a street or postal address or address geocoding. In contrast, reverse geocoding is the reverse process that transforms a pair of geographic coordinates into an address.
Geocoding begins when data in text or tabular form is compared to a reference data table that includes defined map coordinates. When the input data is matched to the reference data, the corresponding map coordinates are assigned to the input data. Reference data is typically based on a segmented street centerline layer that contain information on house number ranges. Geographic coordinates are then interpolated from the estimated location where the address number falls on the segment. For example, if a road segment contain the address range 100 – 119 and runs west to east and the address attribute is 109, then the geographic location would be roughly 50% of the way along the segment on the odd side of the street.
The quality and accuracy of the geocoded data depends on understanding the reference table and data, the methods in which the matches are being produced and the given accuracy once a match is found.
Knowing the format required for the geocoder that you intend to use is critical to getting identical matches. Accuracy depends on the nature of input data including the format and “cleanliness”. For example, input data that includes misspellings, special characters (such as “ \ % # ?) and abbreviations often result in inaccuracy and mismatches. Be prepared to refine your data and re-geocode your data as errors or typos may be found during the process. Finally, it is important to perform a quality control check on your geocoding results by comparing the address locations against other data sources, such as street basemaps.
Geocoding can be done on a case by case basis or in batches using an open-source or commercial geocoding service. There are many batch geocoding services online that are free up to a pre-set level while others that charge a fee. As geocoding becomes more valuable, batch geocoding large numbers of addresses has become costly and geocoding batch services limited.
ESRI’s World Geocoding Service is available to ASU faculty, staff and students. However, the service uses 40 credits per 1,000 address, which is pulled from the ASU University credit pool. Currently, each user in the ASU community has the ability to geocode up to 25,000 addresses. An alternative to utilizing a pre-configured geocoding service is to create your own address locator. Address locators are based on an address locator style that defines reference data used and rules for address format and parsing depending on locator style. Recently, Erica Quintana, a Policy Analyst in the Morrison Institute for Public Policy, created composite address locators for all of Arizona using the Census TIGER files. She has agreed to share them with the ASU community. The address locators and supporting files can be found here.
Aside from using the address locators from ASU, there are many geocoding service options. Here are a few to consider:
Using this locator for batch geocoding consumes credits. ASU provides students and staff with 1,000 credits allowing up to 25,000 batch geocodes. Beyond this amount, it is advised that you look into creating your own address locator as this service consumes a large amount of credits.
This map is a bit of a mystery. At first glance, it seems to be a standard map of the world. Upon closer inspection, odd cartoon faces worked into the outlines of countries and landforms start to jump out. These faces seem to be political figures or rulers of each place.
The President of the United States in 1898 was William McKinley.
The text at the bottom details various battleships, armored and unarmored cruisers, turrets and navy fleets. There is no text describing or explaining the various illustrations for each country, either who they are or what they mean. The only bit of text that is not part of battleship description is a large title at the top reading ‘THE WORLD IS WATCHING’, a slightly creepy sentence that seems to be straight out of George Orwell’s 1984.
This map serves as an interesting historical and geopolitical map. Many of the current boundaries and states weren’t established in 1898.
In Europe, faces can be seen for almost every country. A bear (Russia) looms over Europe.
The most interesting parts of the map are the slightly solemn and serious way the faces are looking out to their neighbors around the world. The serious tone and feeling that the faces set, along with the text describing military tools and weapons, leaves the viewer of this map with the sense of discomfort and intrigue.
What are they watching for? Why is the world watching?
A grim-faced and armed Russia faces the bald eagle that is Alaska. At the time, the Tsar of Russia was Nicholas II.

If you’re looking for aerial photographs of Arizona from the 1970’s, the USGS Orthophotos are a good place to start. The scale for these black and white photos is 1:24,000 and they line up with the USGS 7.5’ topographic map series.
These photos are housed at the ASU Map and Geospatial Hub. While they are not currently digitally available, you can use the AZ Orthophoto Index (1971-1976) Web Map index to see the coverage for your area. Once you've identified the orthophotos you're interested in, simply submit a short Service Request with the photo name, and we'll prepare the physical image for viewing here at the Map and Geospatial Hub.
The ASU Library Map and Geospatial Hub is excited to announce the Fall 2018 schedule of events and workshops.
This semester we’re offering a range of workshops, a demo of Google Earth VR, a new Creative Cartography exhibit with an opening reception, and our annual GIS Day. Follow the links below for more information and registration.
To better aid and streamline access to ASU Library’s collections of aerial photography, the Map and Geospatial Hub is actively creating web map indices. These interactive web maps show the extent of coverage for the photos with the intent of helping aid researchers in discovering resources.
The latest USDA Arizona Photo Mosaic Index (1940-1964) web map serves as a resource to find aerial photo mosaic images produced for the United States Department of Agriculture. This set of historic photography includes portions of Maricopa, Pinal, Pima, and Prescott areas of Arizona. Digital copies of these aerial photo mosaic indices are immediately accessible via Dropbox.
Use the USDA Arizona Photo Mosaic Index (1940-1964) web map to find which USDA aerial photos might best serve your research and education needs:
Navigate through the map to identify your geographic area of interest. Select the relevant mosaic footprints to learn more about each mosaic photo, including its image file name (which can be downloaded directly in Dropbox). You can turn layer visibility on and off to view the geographic coverage offered by each set of USDA aerial photo mosaics.
The ASU Library Map and Geospatial Hub is pleased to host a symposium (mini-conference) dedicated to exploring, examining, and celebrating the cartographic history of the greater Grand Canyon region, the Mapping Grand Canyon Conference.
Theevent unites historians, geographers, cartographers, artists, geologists, environmentalists, surveyors, conservationists, rafters, hikers, librarians, and anyone else with a love for the Grand Canyon for a day of engaging presentations and hands-on activities related to the past, present, and future of representing and creating knowledge about this awe-inspiring region through maps.

In the ASU Library we strongly discourage people from writing on library materials. However, occasionally we come across annotations that give a glimpse of the past.
Prior to coming into our possession, this Road Map of the United States was used by Ruth, Fred, and Billy Wilson to guide them on their “First Trans-Continental Trip” in 1928. This is most likely the same Fred Wilson whose photographs and papers are in the ASU Library’s Arizona Collection.
The family took extensive notes on the map. The trip started on March 18 in Vancouver and finished on May 5 in Chicago. All along the way are notes about where the family spent the night, road conditions, places they visited, and where they ate lunch.
Of particular note are the nine Harvey Houses they ate at and stayed in as they crossed Arizona, New Mexico, Colorado, and Kansas. Harvey Houses were lunch rooms, restaurants, and hotels along the Atchison Topeka and Santa Fe railway. Starting in 1876, Fred Harvey created these establishments to provide good food at a reasonable rate for railway travelers. Harvey House hotels, such as the El Tovar at the Grand Canyon which the Wilson family visited, also catered to the reasonably well off tourist with money to spend on excursions and Native American crafts.
It appears that a few years after this trip, Fred Wilson moved to Phoenix and later purchased Vaughn’s Indian Store renaming it Fred Wilson’s Indian Trading Post. Wilson operated a chain of trading posts throughout the southwest. Perhaps it was this 1928 trip that inspired this business venture.
In Braun and Hogenberg's Civitates Orbis Terrarum, the city of Jerusalem is surrounded by a closed wall that exists to this day. It was ordered by Suleiman the Magnificent and took some four years to build. Viewing from the east, the building at the forefront is the Dome of the Rock (14), built on the Temple Mount, one of the most venerated sites in the Abrahamic religions. Initially constructed in 691, it was rebuilt in 1023 after the original collapsed.
Many of the Christian sanctuaries of Jerusalem are located on the Via Dolorosa, Latin for “Way of Suffering.” This kilometer long stretch was the path Jesus took on his way to his execution. It begins at the Lion’s Gate (41), passes the Pool of Bethesda (18), to the place where Jesus was flogged by the Roman soldiers. The road continues to Pontius Pilate’s house (24) and ends at the Church of the Holy Sepulchre (15). The history of the church dates back to the time of Constantine. Between 326-335, he erected a dome structure that was destroyed by Sultan Hakin in 1009. In 1342, the church was rebuilt in a medieval style. Finally, it was renovated to the baroque-style church of today in 1555.
Some other buildings of note include the prison where John the Baptist was beheaded (28) and the residence of Herod (25). On the southern side of the city is the walled Golden Gate (13) and to the left of that is the court where Peter denied the Lord three times (30).

UPDATE (04/10/2018): This workshop has been cancelled due to unforeseen circumstances. This particular workshop session, on Planetary GIS and Image Processing, will be re-offered in a future semester. We apologize for any inconvenience.
In this lecture and mini-workshop, participants will learn the fundamentals about planetary image data and how it is different from other familiar image formats. This will also include an overview of PDS (the Planetary Data System), the NASA archive of all mission data. There are several on-line interfaces to this archive, but they are often confusing and non-intuitive. Discussed will be some strategies on how to locate datasets of specific planetary bodies acquired from different missions.
Because of the specialized nature of the image data, there will be an introduction to ISIS3. This is a free, linux-based software developed by the USGS, which is the premier toolset for viewing, processing, and analyzing planetary image data.
Finally, there will be a brief workshop in ArcGIS, where processed images will be brought into the ArcMap environment. Included will be a discussion on problems with map projections on other planets and the potential pit-falls of performing surface measurements on non-terrestrial ellipsoids.
This workshop will be held in the Noble Library Instructions Room 105, Tuesday, April 17, 2:00-4: 00 pm. See the listing on Eventbrite for more Information and Registration.
(Note: the date has been changed since the original posting)
Also, check out the Map and Geospatial Hub events calendar for the remainder of Spring 2018.
TRELIS-GS is set of NSF funded workshops to Train and REtain Leaders in STEM Geospatial Science. The goal of the workshops is to provide mentorship, professional development, and support for women in geospatial sciences and to address discipline- and community-level challenges that they may face throughout their career. With the TRELIS project, we encourage women to develop STEM skills relevant to their desired career track in geospatial sciences, and demonstrate by example the types of mentoring skills that will help them catalyze other women training in the geospatial STEM disciplines.
In our presentation we will provide some background and context about the opportunities and challenges for women in geospatial fields, discuss the primary objectives of TRELIS, the upcoming workshop in Madison, WI this spring, and how women and men across the geospatial community can come together to help build a more effective, diverse, sustainable workforce.
Following the presentation, we will reserve time for group discussion and questions on synergistic activities, resources, and activities that you engage in for supporting, training, mentoring, and retaining women in the geospatial field.

She is a member of the International Cartographic Association Commission on Map Projections, and is a Past President (2015 - 2016) of the Cartography and Geographic Information Society – a society composed of educators, researchers and practitioners involved in the design, creation, use and dissemination of geographic information.
Laxmi Ramasubramanian, Ph.D., AICP, is an Associate Professor of Urban Policy and Planning at Hunter College, CUNY. Dr. Ramasubramanian seeks to inform and transform planning practice in order to create a just and equitable society. Specifically, her research examines how the use of digital technologies such as GIS can alter social and political processes, particularly the power of individuals and institutions to create and sustain social change. Her research is synthesized in her first book Geographic Information Science and Public Participation (Springer, 2010). Dr. Ramasubramanian’s second book, Essential Methods for Planning Practitioners: Skills and Techniques for Data Analysis, Visualization, and Communication, co-authored with Professor Jochen Albrecht (Springer, 2018) bridges theory and practice by framing 21st-century planning practices in their socio-political and ethical context. Dr. Ramasubramanian served as the president of the University Consortium for Geographic Information Science (2012-2014) and currently serves on the board of the American Collegiate Schools of Planning. In 2016, Dr. Battersby and Dr. Ramasubramanian were appointed to the National Geospatial Advisory Committee, a federal advisory committee that provides guidance to the federal government on matters of national geospatial policy.
In the last week of January Stanford University hosted Geo4LibCamp, an unconference style meeting bringing together people from the library community interested in publishing, describing, and sharing geospatial data. Sessions were a mix of invited talks and breakout discussions on participant-chosen topics including community best-practices, new-feature showcases, project status updates, metadata and accessioning workflow concerns, and lessons learned.
The institutions represented are all at varying stages of building out their geospatial data infrastructures and have a wide variety of goals. Some already have an established searchable dataset while others are just starting to think about exposing content. Some focus on exposing locally-produced and unique data while others actively collect public datasets to store redundantly. Some choose to host private data behind institution-specific authentication while others focus on exposing only open content. Some don't host any data at all and choose only to aggregate metadata records and link to datasets published elsewhere.
While the meeting was not focused on any particular tool, many of the participants are using GeoBlacklight as a search and discovery interface so many of the talks centered around its use and development. A new addition to the software that was showcased is the ability to display index maps. Index maps serve as a single point of access to a collection geographic resources related to a particular region, for example, digitized maps or aerial photos. See an example from Stanford's EarthWorks catalog. This feature is implemented using a community-developed format called OpenIndexMaps based on GeoJSON.
Another initiative related to GeoBlacklight called OpenGeoMetadata focuses on sharing metadata between institutions. Contributors can expose their metadata through the GitHub organization which allows other institutions to periodically harvest and ingest the records into their own GeoBlacklight instances for wider exposure.
One particularly impressive highlight from the week was a visit to the David Rumsey Map Center. The Center houses many cartographic primary materials and showcases them with a variety of technologies. Rumsey himself presented on the history of mapping San Francisco using digitized maps displayed on the Center's large high-resolution presentation wall. Between talks we were allowed to use the Center's Oculus Rift stations to experience Virtual Reality versions of Google Earth and digitized historical maps.
Many thanks to Darren Hardy, Jack Reed, Stace Maples, the rest of the Stanford staff for hosting and just as many thanks to the entire community for the helpful and informative meeting. The discussions were invigorating and provide a good basis to begin thinking about our own geospatial discovery infrastructure here at ASU.
The Map and Geospatial Hub is pleased to announce the arrival of Jill Sherwood to ASU Library. After a highly competitive search, Jill was selected from a pool of dozens of candidates to serve as the Hub’s new Geospatial Data Analyst. Her work will involve a dynamic combination of geospatial data (metadata) documentation, processing, curation, collection, and analysis.
She brings to the table over a decade of multidisciplinary GIS experience in both the academic and government sectors, involving spatial analysis and modeling and geodatabase design, development, and implementation. Particularly relevant for her new role as ASU Library, Jill also carries a strong background in overall data management and metadata documentation.
Jill is a scientist formally trained in multiple disciplines. In addition to her geospatial expertise, she has experience in laboratory and field research. Jill earned two Master of Science degrees: one in Genetics, the other in Ecology and Evolutionary Biology, both from Iowa State University. When not geeking out over GIS data, Jill can be found hiking the beautiful Arizona landscapes and hanging with her dog, Oskar.
Your ASU Library Map and Geospatial Hub is pleased to offer a fresh lineup of workshops and events for the new semester.
Notable additions to the Spring 2018 workshop lineup include new offerings introducing participants to ArcGIS Desktop. (Thus far, our introductory GIS workshps have been focused on using the open source QGIS software; those QGIS workshops are, of course, still being offered.) Moreover, we're pleased to be offering workshops at the ASU Library downtown location for the first time.
We're proud to again be hosting the School of Earth and Space Exploration's Mars Space Flight Facility as they conduct a couple live demonstrations and hands-on workshop sessions with JMARS, an open-source GIS platform that allows users to retrieve, visualize, and analyze remotely sensed satellite imagery data for multiple planetary bodies, including Mars, Earth, the Moon, and many others.
We're also actively working with our friends from The Ronald Greely Center for Planetary Studies on hosting some of their workshops on applications of Esri GIS software for planetry (non-Earth) analysis and mapping. They'll make excellent companions for the aforementioned JMARS workshops.
We will also hopefully see at least one more instance of Cut + Paste PHX Map Night this Spring 2018 semester. Stay tuned for news on that creative event.
To streamline access to these critically valuable data, and to maximize their impact across the multitude of potential sustainability applications, the Map and Geospatial Hub has deposited the entire USGS 3DEP LiDAR data package into a publicly-accessible instance of Dropbox.
This new web map will be particularly beneficial for patrons interested in accessing the raw point cloud (available in las and laz file formats) and the derived bare earth DEM (available in tif file format).
GIS users can interactively search, navigate around, and zoom in and out of the web map to identify the specific subset of point cloud or DEM data they're interested in.
Once the particular file corresponding to one's area of interest is identified, that file can be easily extracted from the cloud-based Dropbox instance currently being used to store and disseminate those data. Additional details are found in the full text description of the new web map: USGS 3DEP Metro Phoenix LiDAR Data (2014) Index.
So, what are you waiting for? Get busy mapping, greater Phoenix!
As the de facto geospatial data manager at ASU Library, Mary helped process, organize, map, interpret, and document (i.e., create metadata for) the thousands of geospatial datasets currently held in the ASU Geospatial Data Directory. The critical work Mary did laid the foundation for current and future efforts to build a web-based geospatial data catalog.
The Map and Geospatial Hub congratulates Mary on a tremendous career and wishes her a most satisfying extended vacation during her well-earned retirement. She will be missed!

CANCELED - Watch for this workshop to be offered Spring 2018: Accessing Digital Topo Maps for GIS – Thursday December 14, 6:00 p.m.
Join the ASU Library Map and Geospatial Hub for this one-hour workshop on how to access historical (and contemporary) topographic maps going as far back as 1884.
Participants will learn about the various web platforms used for hosting and distributing free topographic maps available in various formats. Workshop attendees will then learn how to import and use the scanned map images in a GIS software platform with other types of GIS layers.
The ASU Library Map and Geospatial Hub is excited to host an exhibition of original cartographic artwork by the students in ASU professor Ellen Murray Meissinger’s Art on Paper class. Point of View is the fourth installment in the Creative Cartography collaboration between the Map and Geospatial Hub and the Herberger Institute for Design and the Arts.
Part of the life cycle of a library is the withdrawal of worn out or excess materials. In 2013 the Map and Geospatial Hub decided to withdraw surplus copies of topographic maps. The resulting stacks of maps were offered to other institutions. A few were claimed but the majority were not.
In 2014 the Hub offered the remaining maps to the School of Art. Meissinger jumped at the offer. She pushed a cart across campus and loaded it up! Viewing this as an opportunity, Meissinger designed a cartographic art assignment for the students in her Art on Paper class. At the end of the Fall 2014 semester, the Hub hosted the first student exhibition, Memories & Movement.
