Kentucky GIS Conference 2024

During the summer of 2024, I introduced new GNSS systems, LiDAR and photogrammetric scanning, and UAV-borne laser scanning into my archaeological research in northern Yucatan. Previous research focused on a Maya imperial capitol that collapsed in a civil war around A.D. 1450. My current project investigates the changing and variable household economic and social organization of Maya peoples living in the aftermath of the imperial collapse and expansion of Spanish power. I began with locating and excavating a group of early colonial households. GNSS systems with NTRIP corrections simplify fieldwork and increase the precision of mapping. A Pix4D ViDoc RTK Rover facilitates 3D mapping of small features and excavation units. UAV-borne LiDAR scanning of three areas of 400 x 400 meters is being used to locate initial excavation targets. I describe in this presentation how I implemented these technologies and the challenges that arose under rural tropical field conditions.

KyFromAbove Explorer is the new tool that allows the user to browse the states coverage of oblique imagery. This tool allows for drawing, measuring, and sharing oblique images. KyFromAbove Explorer can also be integrated directly into other layers and maps. Join this session to learn about how to integrate the explorer into pop-ups, not only in ArcGIS Pro but in Map Viewer as well.

This concise abstract focuses on the meticulous process of collecting high-accuracy GNSS data. It outlines essential steps, including receiver selection and optimal field procedures, emphasizing the significance of adherence to best practices. We will highlight the critical testing phase against control points and error assessment techniques for data validation. Additionally, it touches upon advanced GNSS collection methods like differential correction and real-time kinematic solutions. Practical tips and tricks, addressing challenges like multipath interference, round out the abstract, providing a comprehensive guide for professionals seeking precise and reliable GNSS data.

Managing voter rolls is crucial for accurate elections. This presentation details a geolocation approach to help county clerks update precincts post-reapportionment. Using locators like KY NG911, et al, we can precisely pinpoint voter locations across various address formats. Collaboration with KY's Cabinet of Technology and testing NG911 locators and the national address database enhances accuracy. Geolocation parameters such as Subaddress, Point Address, and Street Address ensure detailed output fields, preserving original inputs during address edits. This maintains integrity in re-match processes for lower accuracy scores. Confidently located voters allow for heat map creation to optimize polling locations, weighted by past election activity. Advanced geolocation and data analysis empower county clerks to manage voter rolls effectively, improving voting experiences and ensuring fair elections.

During this BONUS informative session, you will learn about an overview of the previous state plane coordinate systems, what levels of distortion previous systems created, and the proposed changes in the NSRS Kentucky update. We will talk through questions like: How many coordinate systems will Kentucky have? What grid numbers will these systems be on? What kind of distortion should we expect? ... and many more. We will be focused on the horizontal component of our forthcoming Modernized NSRS... the SPCS2022.
