ACA provides precision topographic maps for the determination of ground and water surface profiles for floodplain delineation. These precision maps enable hydrologic and hydraulic modeling to manage water resources and update Digital Flood Insurance Rate Maps (DFIRM). Using the UCX Large Format Digital Mapping camera and the Riegl 680i 400Khz full waveform LiDAR sensor, ACA creates accurate 3D surface models that are hydro flattened to map critical water conveyances. The full wave form LiDAR performance enables ACA to get results in the most challenging vegetation, wetlands, and forest conditions.

ACA’s map products meet and exceed NSSDA and NMAS accuracy standards. As licensed Professional Surveyors and Mappers, each watershed and floodplain mapping product includes a detailed survey and map report and full meta data file.

ACA also provides more advanced data fusion products with the incorporation of Color Infrared and Hyperspectral imagery. These 3D fused map products enable the highest form of analytical modeling and analysis of water bodies, ground surfaces, wetlands, vegetation, and forests, from the upland, to the river, to the ocean. ACA’s experience in precision watershed map products is industry leading.
