Ltd., Xuzhou, Jiangsu 221000 Abstract: the current construction engineering surveying and mapping node layout is generally loose, need to basic surveying and mapping data collection, multi-level, multi-stage layout mode, clear node location within the area, strengthen the overall construction control effect, realize multi-order mark tilt surveying and mapping node layout, establish POS 3 d drone tilt photography surveying andmapping model, implement surveying and mapping processing in the form of ranging correction. The final test results show that: after the verification of the three test areas, the final elevation and mapping error is better controlled below O.5mm, indicating that in the actual construction surveying and mapping process, the control speed is fast, the measurement accuracy is high, and the surveying and mapping error can be better controlled, which has practical application value.
