A set of solutions based on high-resolution photographic images and three-dimensional models to assist decision-making for ecological environment supervision, improvement, and protection
Tilt Aerial Photography capture aerial images at an angle, so that ground objects within a certain area can be captured from four directions. The high resolution oblique photography can be used for 3D model building, which can be applied in urban planning, attractions sightseeing, security and defense, emergency management, and BIM construction.
DOM has the advantages of high accuracy, rich information, intuitive and realistic, strong realism, etc.
DEM (Digital Elevation Model) describes elevation values across the map, excluding vegetation and man-made structures. It describes “bare earth” elevation. The result can be applied in survey, hydrology (calculate flow accumulation and flow direction), geology, construction, utilities, etc.
Digital Surface Model (DSM) refers to a ground elevation model that includes the height of surface buildings, bridges, and trees.
Digital line drawing (DLG) is a vector dataset of geographic information of terrain features expressed in the form of points, lines, areas or map-specific graphic symbols.
Forestry survey is an important basic work to regularly grasp the current status and dynamic changes of forest resources and ecological environment.
