Impacts
What was accomplished under these goals?
Project accomplishments include the investigation of cutting age geospatial technology such as different UAS with different sensors, 3D modeling and printing, UAS image collection, its accuracy analysis, image processing, GNSS data evaluation, and watershed modeling. Specific areas addressed in this project are: Project 1: UAS mission for 3D modeling purpose. Different UAS, different mission control, and different data processing method were used to create 3D terrain models. Campus terrain were created successfully. Project 2: Terrain based LiDAR system was used to scan a statute and 3D model was created. Students were involved in the procedure to study LiDAR technology, point clouds, survey control, and 3D modeling technology. Project 3: Studied different methods to create 3D terrain model creation based on USGS DEM data. These models serve well as terrain demonstration and hydrology modeling. Project 4: Studied the newest 3D printing technology based on FDM (Fused Deposition Modeling). Assembled a 3D printer with parts 3D printed. 3D printed wildlife skulls are used in wildlife education and provides an economic and conservative education model creation method. Project 5: Positional accuracy assessment of images collected by UAS. UAS images have to be orthomosaiced to cover the entire study area. Different study sites, flight height, mission control, base station, ground control points, and image processing software all influence the final output image. It is an on-going project and large datasets are still processing for the best options regarding UAS image positional accuracy. Project 6: Through the entire project, undergraduate students are integrated into hands-on mini projects. Students had chance to fly different UAS, use 3D printer, see terrain-based LiDAR scanner demonstration, use different GNSS data collector and total station, and use other cutting age geospatial software and hardware. With first hand experience, students are well prepared for their professional intern and future career. Project 7: Satellite images were used to identify and quantify land cover change within a watershed. Analysis is undertaken to quantify water quality change relative to land cover change within the watershed. Project 8: UAS with multiband sensor was acquired to compare UAS based NDVI (Normalized Difference Vegetation Index) data and satellite data based NDVI. High resolution UAS based NDVI is very useful for forest and agriculture management. Project 9: UAS with thermal sensor was acquired to study the application of this sensor in forest management. Pre, during and after a prescribed forest burning, images and videos were taken at the Stephen F. Austin Experimental Forest in 2021.
