The ASU Library Map and Geospatial Hub is excited to be partnering with the Arizona Geographic Information Council (AGIC) LiDAR Workgroup to host the 2019 AGIC LiDAR Networking Symposium!
The event will be a follow-up to first ever Arizona LiDAR symposium held in August 2018. Currently, Arizona has little in the way of comprehensive LiDAR data. AGIC is leading the efforts to obtain statewide LiDAR coverage and create educational platforms that increase public and industry knowledge of LiDAR.
This event will provide an opportunity for interested parties to get together to learn about the Arizona LiDAR initiative and create networks as Arizona moves towards statewide LiDAR coverage.

How Open Data Unlocked Remote Sensing for Forest Monitoring Presentation Summary
Satellite remote sensing has been available for forest monitoring for decades. High costs for data, computing, and analytical options have limited the utility and ubiquity of outputs from remote sensing for inventory and monitoring over large areas. In recent years, satellite data at scales relevant to forest inventory and monitoring have become available on a free and open access basis. This open access has coincided with decreases in software and computing costs resulting in an ability to produce previously unavailable information products. These information products have allowed us to characterize, for the first time, a systematic and consistent depiction of harvesting across Canada for a multi-decadal period in a systematic and repeatable fashion. Further, we have also been able to use time series remotely sensed data products to monitor the return of vegetation on these sites following disturbance, essentially providing a more complete accounting of forest dynamics. New modeling opportunities continue to emerge that allow for enhanced integration of calibration/validation datasets such as from airborne laser scanning. Time series of data has proven powerful to not only capture change, but to strengthen models with additional evidence of status and trends. Scientists are increasingly limited by only ambition and questions posed, rather than cost and computing limitations. In this talk Wulder aims to provide some background on where we were as a community, what has changed and what we have learned. The lessons learned are both technological and ecosystem related.

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 addresses, which are pulled from the ASU University credit pool. Currently, each user in the ASU community has the ability to geocode up to approximately 25,000 addresses. This, however, would use up all of the user's credits. 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 accessed by submitting a quick service request through the Map and Geospatial Hub's Service Request form. (We respond to all requests within two business days, typically much sooner.)
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?

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.
