PLEASE NOTE WE HAVE PRESENTATIONS TO OFFER EVERY WEDNESDAY FOR THE TIME BEING!
You are invited to the next virtual meeting of the Underground Texas Grotto On Wednesday, May 6, at 7:30pm central time. You may join as early as 6:30pm for socializing! (Set a reminder or add to your calendar NOW!) Our speaker for the evening will be Ken Bailey who is working on the Big Bat Cave LiDAR project. With collaboration between The Kentucky Karst Conservancy (KKC) and Qk4, Inc., the Big Bat Cave LiDAR (Light Detection And Ranging) project is collecting, mapping and preserving the fifty-sixth longest cave in the world. It is their primary goal to digitally archive the cave to know better how to preserve its history. Cave mapping generally is collected by hand with compass and measuring tape. Electronic distance meters are being used in cave mapping they are based on the compass and tape survey methods collecting one data point at a time. Cave mapping using LiDAR scanning enhances this process by collecting millions of data points while referencing them horizontally and vertically in 3D space. LiDAR 3D scanning technology analyzes environments to collect data in a point cloud. Digital 3D models of the existing features are then constructed using software. For over a year, the KKC and QK4 have been mapping Big Bat Cave in Breckenridge County, Kentucky with LiDAR. They continue to develop their process in collecting and analyzing the geospatial data and gaining valuable experience below the surface. The research possibilities in Cave LiDAR mapping are just beginning to be explored. Caves have been a preserved record of our past history and climate conditions. This LiDAR data set may shed insights into these paleo-climates and help the KKC preserve the story of Big Bat Cave. Starting at 6:30pm central time, the Zoom meeting will be open for a social hour and hosted by our dear friend Mary Hicks <https://www.facebook.com/profile.php?id=9637317&fref=gs&__tn__=%2CdK-R-R&eid=ARBoWFS33Um5wRhGEVdCFvJQ41yRr5M3Lb3MzxcuGwr7ohvn8X5HR9Z1k7NueSUp_4oknPhPJ-oZ4HUb&dti=2231736016&hc_location=group>. We will begin official business at 7:30pm. The meeting will begin at 7:30pm central time, Wednesday May 6, 2020, and directions to join the meeting on the Zoom app are below. After Ken’s talk, we will have a moderated Q&A - you can use the chat feature to submit questions as they speak, or ask them yourself after they finish telling their tales. Once we've finished with the presentation and questions, you are free to continue to hang out on the Zoom Meeting again for more social time. Make sure to check out the ZOOM app before you need to use it that evening! Post any questions below so that we can help you.
