Real Geographics can produce elevation models of any site we can fly, with data that compares favorably to high-elevation aerial lidar results for a fraction of the price. Unlike lidar, our photogrammetry-based methods produce a “first-return” product most accurately described as a DSM (digital surface model). Accuracy ranges depending on ground control, sensor elevation, and sensor resolution, and can generally be counted upon for the generation of accurate 1m contours.
Wind power is a business that runs on small profit margins. To keep equipment running at full capacity while accommodating variable wind power and an inflexible grid, an energy group wanted to consider a pumped storage facility to hold excess generation during peak wind and release it on demand. Real Geographics provided site selection intelligence that balanced property ownership contiguity, transmission line proximity, protected environments, and a complex terrain analysis procedure. With a “heat map” of likely sites in hand, company representatives were able to focus their ground work on two or three pre-screened areas of high development potential.
Real Geographics assissted Cogan Owens Greene with GIS analysis and mapping in support of the West Linn EOA. We quantified vacant and redevelopable land on a parcel-by-parcel basis for selected employment-related zones, then overlaid development constraints such as steep slopes, flood hazards, and environmentally sensitive land to arrive at realistic and defensible numbers.
