Some aspects on developing a truly low-cost mapping system using handheld GPS and camcorder
Rokhmana, Catur Aries
There are some characteristics for the mapping systems that need to be developing which are low-cost, easy in operation, fast in production, and the appropriate quality. The aerial videography (AV) is one of the interesting low-cost systems. Further, this paper explains some aspect on hardware, processing, and operation. These explanation aspects are include: video camera, airborne platform, handheld GPS, the information extraction, and practical implementation. Some aspects of the processing function such as: ortho-mosaic, stereo-mosaic, motion extraction, and georegistration will explained. Some aspects on using the handheld GPS for sub-meter accuracy are showed. Some of operational aspects show the effectiveness coverage volume and the production time. It is suggested to implement the AV system for producing an ortho-mosaic and DTM with coverage area less than 5000Ha. Both of combinations camcorder and handheld GPS can be fulfilled to produce accuracy up to map scale 1/5000.
