Abstract:In recent years, photogrammetry has been developing. Traditional photogrammetry technology is facing the reform. The feasibility for making topographic map based on DPC and TDOM technology has been put forward. At present. The technology is still in research stage at present. The technology experiment has carried on the exploration by Shandong Geological Surveying Institute by using lowaltitude uav photogrammetry technology. Based on topographic map surveying and mapping project with the scale of 1∶500, lowaltitude uav photography, image processing has been carried out in experimental area, and topographic map with the scale of 1∶500 has been made by using DPC and TDOM technology. The feasibility of the technology has been determined through precision.
