Abstract: With the changes in the use requirements of surveying and mapping geographic information and the advancement of surveying and mapping data acquisition technology, holographic surveying and mapping has become a new idea of basic surveying and mapping data production. In this paper, three collection methods of GeoSLAM backpack, Trimble MX9 vehicle-mounted laser scanning system and DJI M300 UAV oblique aerial survey are used in Guangdong Software Park to obtain holographic data in the park, and then carry out calibration, matching, fusion, classification and processing and carry out elementalization, materialized and three-dimensional production to form the three-dimensional object map data of the park, which provides a basic base map for the location service, management and display of the smart community. The results show that the community holographic map produced by laser combined with oblique aerial survey is better than traditional photoelectric ranging methods in terms of richness, accuracy, completeness and precision.
