"Single unitization" actually means that every object we want to manage individually is a single entity that can be selected, attributes can be attached, statistics can be queried and so on.
Due to its generating technology mechanism, the oblique photography automatic modeling has a "skin of skin", which cannot be implemented for GIS operations such as building selection, attribute query, spatial query, and thematic map operation. Only with the ability to “single” can data be managed, not just viewed.
Aerial photogrammetry is generally low altitude flight, which is easy to operate in airspace and will not be affected by extreme weather. At the same time, it is not limited to the needs of take-off and landing sites. It only needs to select a relatively flat site for take-off and landin...
As we all know, aerial photogrammetry technology is playing an increasingly important role in urban planning and construction. Moreover, compared with the traditional topographic survey technology, aerial photogrammetry technology has the advantages of small volume, light weight, ra...
After the LiDAR data is obtained, the data can be post-processed only after data preprocessing. After the data preprocessing, there is a data checking software to conduct a preliminary check on the data results. The general data format check has the follo
