Aerial imagery data

Provide a strong foundation for the comprehensive digital transformation of society

By utilizing aerial cameras, LiDAR, and various sensors to capture high-resolution digital color imagery and elevation data, we provide processing and services for aerial surveying data including DOM, DSM, DEM, DLG, and DRG. These 4D mapping products are interconnected and complementary, collectively offering rich geospatial information data for modern surveying. As essential tools for spatial analysis in GIS systems and fundamental components for real-scene 3D construction, they provide robust support for society's comprehensive digital transformation.

DOM

Digital orthophoto (DOM) has the advantages of high accuracy, rich information and intuitive reality. It has good interpretation, measurement and management performance, and is used to generate topographic maps and thematic maps of various scales. It is the basic data source of geographic information.

DEM

A Digital Elevation Model (DEM) is a dataset containing the planar coordinates and elevations of regular grid points within a specific area. By acquiring terrain elevation data, it enables digital simulation of surface topography and includes essential information such as contour lines, slope gradients, orientation, and slope gradient rates. This model finds extensive applications in various terrain-related fields including surveying, hydrology, meteorology, geomorphology, geology, and military operations.

DSM

The Digital Surface Model (DSM) is a terrain elevation model based on raster data structures. It not only contains elevation information of the terrain but also includes elevation data of surface coverings such as buildings and vegetation. This enables DSM to more accurately reflect surface topography and variations, providing detailed and precise elevation data for various applications.

DLG

Digital Line Graphics (DLG) are vector datasets that preserve spatial relationships and attribute information among topographic map elements. With compact data sizes, they enable efficient layering and rapid thematic map generation. By integrating with other geospatial products, DLGs effectively fulfill diverse analytical and decision-making requirements in Geographic Information Systems (GIS).

Application field

Urban planning and construction

Provide accurate data support for urban land use, transportation planning, environmental monitoring, etc.
Agriculture

Plays an important role in agricultural management such as precision agriculture, land resource survey and crop yield estimation.
Geological and resource survey

Early warning and assessment of geological hazards through the measurement and identification of landforms.
Environmental protection and monitoring

Monitor vegetation coverage, water changes, pollutant discharge and other conditions to provide timely and accurate information for environmental protection.
