In-Situ Sensing of Stream Flow and Flooding using Deep Learning Sound Classification
Climate change is creating dramatic and unprecedented changes in stream flow, resulting in hazardous conditions due to overbank flooding, flash flooding, debris flows, and landslides. Satellite based weather forecasting along with traditional monitoring can predict hazardous stream conditions in many cases, but often falls short due to microclimate variations and the lack of fine-grained stream…

Stereo camera with powerful vision neural chip for geo applications: rockfall detection, 3D rock characterization
Here we describe two innovative geo applications using the Oak-D Lite stereo camera containing the Intel Movidius Myriad X Vision Processing Unit. Some of this work is described in Kemeny and Kim (2023). In addition, we reference the work of Jaykumaran (2024) who provides a thorough introduction to the Oak-D Lite camera and describes object…

HED Trained AI Edge Detection Model for Geo Applications: Rock Discontinuity Delineation, Block Size, Rock Mass Classification, Slope Loosening and Movement
The work described here is discussed in Kemeny and Kim (2023). A large AI model was trained on a variety of different kinds of edges, as described in Xie and Tu (2015). The AI technique is called Holistically-Nested Edge Detection (HED), and considers holistic image training and prediction similar to Convolutional Neural Nets, and nested…

Every Geo Person Should Know What a Gaussian Splat is (and NeRF as well)
I will post some interesting stuff here soon. In the meantime, you can watch a great webinar on Gaussian Splats and NeRFs put on by GeoWeek (their annual conference in Denver in February is not to be missed if you want to experience the latest geospatial technologies). Click on the following link and then go…
