The U.S. Geological Survey’s (USGS) National Geospatial Program (NGP) provides free, publicly available geospatial data as a key part of its mission as the United States national civilian mapping organization. These data are widely used for many applications. For example, elevation data provided as part of the 3D Elevation Program (3DEP) plays an important role in many geospatial research fields. Geographers, archaeologists, and geologists use slope calculations and terrain models to conduct site selection and studies on species’ habitats, consider existence of ancient artifacts, search for minerals, and investigate hazards and resilience modeling.
As part of 3DEP, the USGS provides high resolution light detection and ranging (lidar) point clouds, and derived elevation data, including digital elevation models. The NGP also provides hydrographic data that are part of the National Hydrography and Watershed boundary datasets as well as US Topo maps. These are available for download through the USGS and can be processed using open source and commercial software applications.
This workshop will introduce attendees to the USGS lidar derived elevation models, topographic maps and hydrographic data that several academic institutions are integrating into curricula. USGS instructors will familiarize participants with available USGS sources of topographic and hydrographic data. Step-by-step guidance will demonstrate how to download these free, publicly accessible data and introduce the ways in which it can be processed and analyzed in an open source software.
Lidar, topographic, and hydrographic data visualization and processing plays an important role within several fields of study. Giving students and researchers a chance to examine the data creates engaging and productive way of studying physical environment and its impacts. Overall, this workshop introduces publicly available geospatial data and provides fundamentals on incorporating them into your classroom and research.
