Topographic maps are typically used by our clients in planning infrastructure and resource management. The information conveyed in this type of map can include contour lines, spot elevations, hydro-enforced breaklines, and other required elevation data.
Using photogrammetric methods, we interpret aerial photography, lidar data sets, and other remote sensing data to develop topographic maps. Once we have aerial imagery, we utilize both softcopy and analytical stereoplotter systems to extract the required topographic information. Our mapping instruments all employ high-speed computers and capture software, providing for efficient collection of map data.
Our softcopy systems include DAT/EM's Summit Evolution digital photogrammetric workstations. These advanced software driven systems use high-resolution scanned aerial photographs and digital aerial imagery to perform 3D data collection.
Our analytical stereoplotter systems enable us to view film transparencies in 3D, equivalent to softcopy methods, for similar mapping applications.
