Once the size and scale of the mapping has been determined, GeoMetrics team designs flight lines for aerial photography. Ground control is needed to scale and orient the photography. The GeoMetrics experienced field crews lay targets which are visible from the air. The airplane then flies along the pre determined paths with GPs guidance. Aerial photography is taken and the position of the center of each photograph is recorded using GPs Additional sensors such as lasers and radar can also be synchronized with the photography.
Most mapping is done using black and white photography.
Other films such as infra red can be used for special projects. The resulting photography is then digitally scanned. The digital files are viewed stereoscopically so that elevations and features can be captured on the computer. The final products include topographic and planimetric maps and ortho-rectified photography. These products are available in both digital and hard copy formats.
