Viewshed Analysis

With advanced Geographic Information Systems (GIS) and Computer Aided Design (CAD) capabilities, CRA’s geospatial technicians and cartographers use cutting-edge technology for both increased efficiency and high quality data management. Our staff has over 75 years of combined experience and can work with virtually any CAD/GIS data that our clients desire. CRA has extensive experience in all levels of GIS development and implementation-from agency-wide GIS-based cultural resource management plans to simple, project specific GIS’s. CRA uses GIS to holistically integrate virtually all aspects of our services, including landform analysis, data collection with survey-grade (sub-meter) global positioning system (GPS) units, cultural resource geodatabase development, and spatial analysis of archaeological sites. CRA can produce detailed maps and graphics in print or digital media, depending of the needs of the client. CRA can deliver what you need, when you need it.
