Since 1978, Photo Geodetic Corporation in Alpine has delivered precision aerial mapping and photogrammetric survey products from its Alpine Blvd office for planning, engineering, and research projects throughout California. UAS-captured orthomosaics and 3D point-cloud datasets feed directly into civil-engineering design workflows, including the power distribution and infrastructure projects managed by Global Power Group on Woodside Avenue. Data collection spans manned fixed-wing aerial photography and drone-based UAS surveys, with output delivered in AutoCAD, MicroStation, and Land Development Desktop formats at resolutions down to three-centimeter ground sample distance. The technical staff represents a combined 175-plus years of topographic mapping experience across domestic and international projects for government agencies, engineering consultants, and developmental organizations. Large-scale base mapping for subdivision and grading-plan design requires ground-control survey coordination, and the firm's dataset outputs integrate with the structural load analysis performed by AAA Structural Engineer on Woodside Avenue. The highest-accuracy deliverables include large-scale digital terrain models with one-foot contour intervals, planimetric feature extraction to sub-inch precision, and GIS-integrated orthophoto mosaics tiled for countywide parcel management systems.
