2022 OKSCAUG User Group Meeting at Broken Arrow

8:45 - 9:30 a.m. 

Presenter : Clint Myers, City of Broken Arrow

Presenter Title : Muscogee Creek Nation Allotment Map- GIS & History

Abstract:

Our GIS department received a request from the Broken Arrow Museum to produce a map like one published in the Tulsa World, which depicted the original Creek Nation allotments overlain on a current Tulsa map.  This was to be part of the Museums Land Acknowledgement Project. The museum provided us with a link to an online version of “Hastain’s township plats of the Creek Nation” published in 1910, that documents the Creek Nation Allotments following the Trail of Tears.  We were able to download, georeference, and create a mosaic of these images for areas corresponding with the City of Broken Arrow Fenceline. We used this mosaic to create a simple Web Application that utilizes the “Swipe” widget to compare the historic map with the current features.

While this is very interesting and useful in and of itself, we wanted to go deeper, and provide a way for people to search by an Allottee’s name, Allotment number, etc. However, since we have limited resources, we couldn't dedicate the time necessary to digitize each polygon and manually populate the corresponding attributes with the information from the map. So, to accomplish this, we have digitized the polygons for each parcel, and created attributes to hold the information to be extracted from the historical map. We have partnered with the Broken Arrow Museum to allow interns to populate the polygon attributes using a Web Map Application that is still under development. This project has vast potential far beyond the City of Broken Arrow Museum’s use, and we are excited for the opportunity it has for connecting people to the land in a special way that honors those who have come before us.

Presenter : Ty Simmons, INCOG

Presenter Title : Nifty Arcade Expressions

Abstract: This presentation will highlight examples of how INCOG has employed Arcade expressions to enhance some of their web maps.  The speaker will present examples of how Arcade was used to change symbology and enhance pop ups without modifying underlying attributes. 

Presenter : Hunter Hampton, EagleView

Presenter Title : EagleView High Resolution Imagery

EagleView will present high resolution aerial images, with detail as small as sub-1”, from orthogonal and all four cardinal directions with every feature and landmark photographed from multiple directions. The images are digital and are linked to a computer-based map of the entire surveyed area (with each pixel have x, y, and z values) to enable z-values for vertical measurement and elevation tools. This presentation examines the varied uses of EagleView and its application in the GIS services, Assessment Offices, 911 operators and for field officers showing a profitable investment because the cost and use can be shared over multiple county departments.  We will also show how Eagleview imagery can be used in ESRI Products as well as our new 3D Mesh product.
