Fostering GIS in Local Government: Non-GISers Using GIS
The City of Grapevine began its GIS journey over 20 years ago, and within a few years most, if not all departments gave complete buy-in. As with any small government GIS shop, an obvious pain point developed; too much work for limited staff resources. Furthermore, to provide value-driven GIS services efficiently for all customers with no chance of increasing staff time or positions was not only frustrating, it seemed impossible. The concept of empowering customers with GIS technology became a new business goal. The foundation of this goal was achieved by fostering the use of GIS by non-GISers through web-based services and apps such as Map Viewer, ArcGIS Collector, ArcGIS Survey123, ArcGIS Tracker, and Community Analyst. The examples showcased in this presentation may not necessarily fit into your organization, however it is guaranteed the technology utilized can be leveraged by your customers.

Using Data in the Field - Transitioning from Explorer to Field Maps
Our Public Works guys LOVE being able to use our GIS data in the field for line look-ups using Explorer and other related apps on their cell phones. There's a few problems we've been facing with that game plan - small screen, different platforms, limited to one app at a time. So we are now transitioning to the new Field Maps app and it is solving most of our issues. I'll demonstrate the new app and show how we overcame the biggest issues.

Telling the Story of Lost Doctor Who Episodes
GIS is used in many fields like utilities, public safety, land development, and more, but what about applying it to pop culture? One particular genre in British pop culture is Doctor Who, the world's longest running sci-fi series. Most people are familiar with the series, but many do not realize some of the early episodes are missing from the BBC's archive. Over the decades, missing episodes have been recovered all around the world! This presentation is divided into two sections. The first section gives a synopsis of the history of why these episodes are missing. The second provides the meats and potatoes of using GIS to map the recovery locations by using StoryMaps.

Enterprise Databases: Tips and Tricks for a Distributed System
Enterprise databases are more than just oversized file geodatabases. They offer many capabilities and features not available in other databases. Yet all these additional features come with their own set of special requirements and considerations. This presentation will focus on topics that help you get the most out of your enterprise database system. Database design and modeling, automating data, and prepping data for web publication are all areas that will benefit from the tips and tricks demonstrated in this presentation. Having a thorough working knowledge of these tips will help your organization save time, will automate work flows, and extend the usefulness of your system throughout your organization.

LARGE-AREA LAND USE/LAND COVER CLASSIFICATION OF VERY HIGH-RESOLUTION IMAGERY: ACCOUNTING FOR SPATIAL BIAS IN SAMPLE DATA
We present a geographic object-based image analysis (GEOBIA) approach that classifies a large mosaic (> 6000 km2) of National Agriculture Imagery Program (NAIP) orthoimagery into land use/land cover categories using a random forest (RF) supervised machine learning algorithm. A total of 36 variables were generated for each object. To account spatial structures of sample data, semivariance on each predictor variable was run to determine distance at which samples are spatially independents. The final RF model produced 94.8% overall accuracy and a Kappa statistic of 94.1% from independent samples collected after post-classification using stratified random sample with equal allocation. We suggest using area-based class level accuracy measures rather than overall accuracy to determine classification accuracy using GEOBIA approach. This study demonstrates a cost-effective way of producing an accurate multi-class LULC map using high-spatial/low-spectral resolution orthoimagery.
