The Advanced Resource Technologies group at the University of Arizona was approached by the Agricultural Research Service to provide a seamless polygon layer that would allow an internet-based rangeland decision support systems to distinguish between land management areas across a variety of agency jurisdictions. This layer would provide analysis boundaries for reporting summaries of temperature, precipitation, cover, land use, hydrography and other variables. The reports are to be used to establish best management practices for land management. These analysis masks were to be synthesized from existing GIS sources expressing State, Forest Service, BLM, and Tribal grazing allotments, city, National Park, and military installation boundaries. In combining so many data sources the challenge becomes one of integrating layers acquired at different spatial resolutions, by differing methods of acquisition, differing QAQC standards and containing attribution supporting varying goals. A simple geometric union of layers proliferates a multitude of topological errors as well as a confusion of conflicting attributes and too many polygons to realistically represent with an internet application. A workflow of geoprocessing operations and attribute management had to be established to assemble the layer to topological standards and insure the flow of appropriate attributes from the source data into the final product with the inclusion of metadata attributes. The workflow specifications must be closely documented and easily replicable. This presentation will detail the challenges and solutions of the design.
ADOT is currently replacing their LRS system with Esri Roads and Highways. The new GIS/LRS system will allow for real time spatial data interaction between multiple systems and data warehouses inside the agency. The new solution will be used to input and house the e911 data for the agency and will support the update and maintenance of local road data for e911 applications. This presentation will talk about the challenges the agency faced, why the agency pursued Roads and Highways, the solution we implemented, and benefits of the new system. The presentation will also discuss the future for ADOT’s LRS system for integrating GIS into non-GIS business units at ADOT and the future this new product opens up. This presentation will discuss some technical architecture, but the majority of it will be talking about the major concepts. There will even be a guest practitioner to quickly share his experiences.
Geodesy provides the framework to reliably combine, analyze, manage, and manipulate spatial data in GIS, especially high-accuracy data. But geodesy often seems overly technical and inaccessible to users. To counter that, geodetic principles are explained conceptually, with emphasis on visualization (maps!). Topics include geodetic and vertical datums, map projections, GPS, accuracy, metadata, and how NOAA’s National Geodetic Survey (NGS) provides the foundation for geospatial data in the US.
As Next Generation 911 (NG911) is implemented, the importance of accurate GIS datasets will be critical. Accurate, timely boundary information for fire districts, EMS and town/city limit boundaries are required for GIS-based dispatch of emergency response resources. Rural communities face many challenges related to E911 and NG911 implementation including technological and funding limitations. This presentation will describe the issues encountered and research conducted related to the determination of authoritative fire district, EMS and town/city limit boundaries for the State of Arizona 9-1-1 Program Office Map Development and Enhancement Project for Navajo and Apache Counties, Arizona. Conflicting data sources, limited GIS resources in rural communities and fire/EMS boundaries created “in a box” will be explored, as well as the need for workflows ensuring more timely and accurate boundary information available from one authoritative source will be discussed.
GIS is used at the AZDOR to help distribute tax revenue more accurately and efficiently. Some taxpayers are required to report their property and sales by location. It's important that the AZDOR be ready to assist these taxpayers to accurately report.
Map projections are distorted (a Fact of Life). Linear distortion is difference in distance between projected coordinates and true ground distance. Low Distortion Projections (LDPs) minimize distortion by covering the largest area with the least distortion possible. But these goals are mutually exclusive, so it is an optimization problem. We show how it can be solved using LDP Design, an online application with an intuitive map-centric interface for interactively designing LDPs in the Cloud.
The development of minimum metadata standards for GIS data and its derivatives is one of the primary recommendations from the ongoing collaboration between the geospatial and survey professions within Arizona. The use of GIS data and products continues to grow and will continue to do so as additional professions further integrate geospatial data and products into new applications. More and more government operations rely on GIS inputs and/or applications to support their customer services. The general public is continually exposed to location-based products through mainstream offerings such as Google Maps, GPS location and routing applications, and Open Data initiatives. This presentation will propose GIS metadata standards that achieve the following:
• Provide "quality indicators" to the end-user that assists them in determining appropriate and inappropriate uses of the data or product.
• Provide a clear delineation between survey and non-survey products.
• Include information on attribute data.
• Specifically include intended uses of the data or product along with use limitations.
This presentation overviews a new way of approaching webpage structuring by walking through programming a simple web map app, using Web Components technology as provided by Google’s new Polymer framework.
Web GIS application development is fraught with many pitfalls that can leave GIS professionals struggling through technology shifts and custom development challenges. IT Managers also struggle with managing the high costs of custom projects and the inherent risks associated with maintaining the skills to build and manage complex applications. Building meaningful and powerful web-based applications for end users can be expensive, challenging, and increasingly complex. Configurable software now provides the ability to build sophisticated, well-integrated and flexible applications, without the risk and expense of custom development. In this presentation, we’ll explore how GIS professionals can leverage configuration to create powerful and elegant applications across the enterprise and the Esri ArcGIS platform. This will include a live demonstration of web-based GIS applications.
General Regni served 40 years active duty in the United States Air Force—four as a cadet at the Air Force academy and 36 years of commissioned. His military assignments spanned Personnel, Training, Education and command positions.
In his keynote presentation General Regni will address a number of topics beginning with airplane history followed by the evolution of Remotely Piloted Vehicles (RPVs) in the military and the evolution of commercial unmanned systems. He will also give an update on happenings at the Federal Aviation Administration (FAA) and talk about commercial applications of unmanned aircraft, including some of the limiting factors such as safety, frequency spectrum, privacy and security. As an expert in the field, General Regni has identified opportunities for the use of unmanned systems and will provide details on three commercial applications that are ripe for Arizona.

This luncheon presentation explored the ramifications associated with establishing boundaries for political and statistical purposes in the Unites States. Strip annexations, gerrymandered voter districts, and federal regulations affected by Census Designated Places are all examples of boundaries that can create problems or conflict. In this discussion, we see first-hand how some boundaries drawn with the best intentions can create problems for some and opportunities for others.
Traditionally GIS web maps have been created two ways. Either using GIS server software designed for small workgroups or trying to shoehorn GIS data into Google Maps or other online mapping APIs. This of course results in solutions that are just one big compromise after another. If there was only a way to use the power of Google Maps, yet still use a spatial database to store and perform spatial analysis....
But of course there is. James will showcase serving up GIS data in Google Maps using some of the best spatial database tools out there. We'll be showcasing PostGIS, Node.js, GeoJSON, Angular.js and other cutting edge server technology to create a full blown "GIS Server" solution on the Google Compute Engine. Fully hosted, fully responsive (runs great on smartphones and tablets) and is completely open source. We'll be showcasing how to set up PostGIS in the Google Compute Engine cloud, load up data into it. Install Node.js and set up the node server. Then integrate it into Google Maps using the new Google Maps Data Layer.
We'll make sure to keep it at a high enough level anyone can follow along and enjoy (bring your laptop, smartphone or tablet to try it out yourself as we go along) but we'll dive deep into node.js and Google Maps Data Layer for those who like to see how the sausage is made.

Almost everyone uses street addresses as location points on maps. But addresses are frequently inaccurate, incomplete or invalid. How can you quickly check, correct and standardize hundreds or thousands of addresses? How do you make sure that the addresses really exist on the ground? This presentation will share practical address data management tips that you can use to improve the quality of your addresses.
In general, address management includes steps to correct, standardize (to USPS standards), add additional details such as ZIP+4, and validate street address delivery points before locating them and using them in GIS applications. And it can be integrated seamlessly into your existing business and GIS workflows. Address management uses products and services certified by the US Postal Service Coding Accuracy Support System (CASS) to meet their accuracy standards for obtaining postage discounts for bulk mailings.
There are many CASS-certified commercial products and services available on the market. Some are reasonably priced and a few are free for limited testing and development use. The City of Phoenix uses a variety of products and techniques to check and verify thousands of addresses in large business databases and improve the accuracy of address locations in mapping applications.
Please join us for practical tips, examples, demos that show how to solve many common address problems.
This discussion will include a brief introduction to the Geographic Support System Initiative (GSS-I). We will explore the process, benefits, and challenges of using locally derived GIS data for update of the MAF/TIGER system in preparation for the 2020 Census.
