Aspen CRM Solutions delivers highly accurate topographical data to surveyors in the cultural resource, engineering, mining, and agricultural communities. We combine high resolution aerial photography with precision GPS data to generate georectified orthophoto maps, digital elevation models, and 3D point clouds.
UAVs offer key advantages over traditional archaeological aerial imaging with their ability to cover large areas at a fixed altitude and speed under a wide range of wind and weather conditions. Their flexibility and speed offer you significant potential cost savings in person hours and equipment fees relative to conventional survey and mapping techniques and other forms of aerial photography.
Orthomosaic Images
Our orthophoto collection services are capable of generating resolutions of less than 2 cm per pixel, with accuracies sufficient for 1-foot contours when combined with ground control reference points.
Digital Surface & Terrain Modeling
- We produce CAD and GIS compatible digital elevation, surface, and terrain models useful for cultural resource managers, designers, engineers, and land managers. Visualize archaeological site conditions and drainage plans, survey quarries and landfills, or conduct a flood risk assessment.

Survey Grade Topographic Lines
- Due to the nature of creating accurate and precise Orthomosaics with sub-centimeter accuracy, topographic lines with intervals of 10 feet, 5 feet, 1 foot, and even smaller are easily possible. Our topographic lines can take into account objects such as vegetation and buildings or remove these objects so that only the true terrain is taken into consideration.
Reflectance Modeling
- We cover a wide range of spectra needs, whether you are interested in NDVI analysis of cropland or forests, thermal infrared for biological or soil conditions, hyper-spectral sensors for specific elements of interest, or LiDAR.
