Mark Christiano, the Kaibab National Forest’s geographic information systems coordinator, was recently honored with the Regional Forester's Innovation in Technology Award for the Southwestern Region of the Forest Service. The award "honors exceptional creativity" and "recognizes exemplary contributions that advance and promote the transfer of knowledge and technology," according to the Forest Service's nomination guidelines. Christiano was recognized for his efforts to bring together diverse stakeholders from across the state to support cooperative investments in technology and to promote data-sharing partnerships.
Christiano played a vital role in organizing the Arizona Geographic Information Council (AGIC) LiDAR Workgroup, which promotes efforts to obtain statewide LiDAR in Arizona by 2023 and values the exchange of information through education and outreach. Through this workgroup, Christiano, along with Jenna Leveille (deputy state cartographer for the Arizona State Land Department), conceived the idea for the Arizona's first-ever LiDAR symposium, which was held in August 2018. The symposium originally grew out of Christiano's desire to best inform the planning and implementation of forest restoration work across northern Arizona through use of high-quality LiDAR data.
Since this first symposium, the LiDAR Workgroup, including Christiano and Leveille, and in conjunction with the Arizona State University Library Map and Geospatial Hub, organized a follow-up AGIC LiDAR networking symposium held at the Map and Geospatial Hub in May 2019. The symposium was a huge success as it brought together stakeholders from public and private entities to create networks that support the acquisition of statewide LiDAR coverage. Opportunities, such as the recent symposium, help in achieving the objectives of statewide LiDAR coverage and the creation of educational platforms that increase public and industry knowledge of LiDAR.
"The LiDAR symposiums and work group have provided a platform for the exchange of information between the Forest Service and stakeholders in and around the state," said Ariel Leonard, forest planner on the Kaibab National Forest. "Mark’s leadership and coordination facilitated multi-party LiDAR acquisitions, resulting in a wide range of efficiencies and cost savings. Using his unique combination of technical, communication, and facilitation skills, he has made this huge accomplishment look easy, which it is not."
Christiano continues to advance LiDAR in the State of Arizona by serving in a leadership role on the AGIC LiDAR Work Group, which has achieved many successes since its inception in June 2018. Christiano was presented with his award by Southwestern Regional Forester Cal Joyner at a ceremony in Albuquerque last month.
"I feel really honored to have received this award," said Christiano. "In many ways, I feel this was a group award. A lot of partners, both from the Forest Service and the greater statewide GIS community, have come together to support projects of mutual benefit and to collaboratively fund the collection of this critical data."
Congratulations Mark!! This is a well-deserved award!

This hidden gem within our collection now has an index. The Navajo Project Aerial Photos have always been available to the public but now the detailed aerial photographs of northeastern Arizona are ready to be known. These black and white aerial photographs are from 1951 with an approximate scale of 1:30,000. The Arizona counties covered in these photographs are: Coconino County, Navajo County, and Apache County.
The geometry for this index layer was initially digitized using Google Earth through visual interpretation techniques. The boundaries of each polygon feature were manually created by students who visually matched geographic features depicted in each flight sequence, defined by flight number and/or flight orientation (north-to-south / south-to-north / east-to-west / west-to-east). In 2019, years after the original creation of the index layer, staff at the Map and Geospatial Hub worked to simplify the index geometry by merging multiple polygons pertaining to the same flight, thereby reducing the total number of features. Geometry and attribute editing were done in ArcGIS Pro.
The aerial photographs are physically located at the Map and Geospatial Hub and are currently not available in digital format. If you are interested in viewing some of these aerial photographs for a certain section, please use the Navajo Project Aerial Photography Index Web Map (1951) to select the section you’re interested in. Once you have identified the area, please submit a Service Request with the Flight, Start, and End numbers and we can gather the physical image(s) for viewing here at the Map and Geospatial Hub. If you need them in digital format, these 10in x 10in photographs fit in the scanner we have provided for our patrons to use at the Hub. Feel free to come in and scan the photos you’re interested in.

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.

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?
A grim-faced and armed Russia faces the bald eagle that is Alaska. At the time, the Tsar of Russia was Nicholas II.
