Mobile Data Collection, Mapping and Spatial Analysis

EDM provides state-of-the-art mapping and spatial analysis support with the latest ArcGIS, AutoCAD and CartoPac software and Trimble hardware featuring sub-foot GPS accuracy. A full project cycle might include planning and field study maps, make-ready work drawings, a construction atlas, as-built drawings and an operations and maintenance plan atlas. Where needed, spatial data is collected in the field using custom, project-specific forms based on CartoPac’s GPS/GIS-enabled mobile data collection platform. EDM uses natural resources data to model environmental impacts, compare project alternatives and develop appropriate mitigation measures. Mobile data collection integrated with cloud-based mapping streamlines work flow, improves accuracy and maximizes worker efficiency.

Featured Project

Tasked with delineating priority structures for eagle-friendly electrical retrofits in a 12,000‑square-mile service territory, EDM modeled the region in GIS, using habitat, nesting, and observational data to calculate the relative priority of each 30-meter grid cell. In an iterative process, features in each data layer were assigned positive or negative weights based on the scientific literature and EDM’s deep expertise in avian protection planning. Priority areas were smoothed and aggregated using nearest-neighbor techniques, generating minimum-sized polygons for field personnel and planners. Deliverables included identification of eagle priority areas and an ESRI model, facilitating improvements and updates as new data become available.
