Photogrammetry
Photos = light / Gramma = to draw / Metron = to measure
• The science and technology of obtaining spatial measurements and other geometrically relevant information from photographs.
• Photographic analysis, using basic equipment and simple geometric concepts, provides adequate approximations to:–Distances and areas–Elevations
• Sophisticated digital raster images and analytical techniques yield precise Digital Elevation Models (DEMs): –Thematic GIS data–Other derived products
Photogrammetric topics:1. Determining the scale of a vertical photograph and estimating
horizontal ground distances from measurements made on a vertical photograph.
2. Using area measurements made on a vertical photograph to determine the equivalent areas in a ground coordinate system.
3. Quantifying the effects of relief displacement on vertical area photographs
4. Determining object heights from: – Relief displacement measurements.– Measurement of image parallax.
5. Using ground control points.6. Mapping with aerial photographs.7. Preparing a flight plan to acquire aerial photography.
