Applying Ground lidar and aerial photogrammetry combination technology in assisting large scale urban planning map charting

摘要

Appropriate urban development planning is the basic interaction of humanity and environment. Urban planning map with accuracy, wide range and vision are the essential. Urban planning map on 1 to 1000 are base map of infrastructure. Fast and correct map production process is the serious work for above all. The traditional topographic survey although hold the high accuracy but lack of fast update. Aerial photogrammetry has wide range and fast but insufficient accuracy for the need of large scale urban planning map. For solve these problem, this case present aerial photogrammetric and ground light combination technique to enhance the overall accuracy and shorten the serious mapping process., Carries on the high accuracy scanning all of the artificial objects and lead into the mapping process to prompt the accuracy and speed, assist the topographic map extension draw into the urban planning map. After 4 teams by 5 weeks comprehensive field survey, the results approximately 1600 hectares in the Tainan Randa area surpasses 95% above the qualified rate to complete the approval by divides a check area every 200 meters to carry on the random sampling and the actual survey process., The surveying and mapping system measured achievement, Becomes the first successful case in using the ground light is auxiliary to measure the 1/1000 topographic maps the entire Taiwan.
