Geospatial Technology (RS and GIS): I also use geospatial technologies such as GIS and RS to solve environmental issues. I have reviewed the existing knowledge of RS and GIS in alpine treeline studies. I have also used a multiscale approach to understand treeline dynamics at regional and local scales with the help of Landsat and high-resolution Digital Globe satellite imagery (Chhetri et al. 2017 Journal of Mountain Science). Moreover, under a fiber network and database management project, I am reviewing the CAD-based, existing fiber optics cable network of the Texas A&M University campus and preparing a geodatabase model in order to incorporate surveys and existing data into geographic information systems. The ultimate goal of this project is to create a user-friendly fiber optics cable database and network management system by using cartography and geovisualization, online mapping, and spatial modeling techniques. Some of my key responsibilities under this project are supervising undergraduate researchers, installing and handling the RTK GPS unit, field surveying to locate underground and aerial fiber lines, collecting GPS points, uploading data into the server, and creating a database and user friendly maps.
