15-20cm spatial resolution for DTM
7.5cm spatial resolution for DSM
The rise of 3D data in GIS planning and mapping platforms indicates the growing need to have a stronger context and deeper understanding of the world around us. Digital Surface Model (DSM), Digital Terrain Model (DTM), and Digital Elevation Model (DEM) products tell the story of the earth’s surface, from capturing both natural/built features of the environment (DSM) to just natural/bare earth features (DTM/DEM).
Industries from Utilities to Transportation, Telecommunications to Government have recognized the value derived from DSM data. And since the quality of DSM products are measured by the accuracy of the elevation at each pixel, Vexcel’s aerial data supports highly precise DSM derived information.
Quick Access to DSM Data
DSM data is now more readily available via Vexcel’s API, allowing you to quickly access smaller chunks of data instead of massive megabytes of unwanted content. End users can select specific areas of interest and receive the data in a GeoTiff format via WMTS. The end result? More consumable DSM content in a file size that’s ready to be integrated into your third-party platform.
Did You Know?
Vexcel’s DSM has a pixel-to-data match with our True Ortho and Multispectral (NIR/CIR) imagery. The result? A perfect spatial alignment between elevation data and imagery for a more consistent and trusted output.
Greater Accuracy for Improved Analysis
Vexcel’s advanced camera systems capture more than just a pretty picture; they collect the elevation data simultaneously, resulting in a pixel-to-pixel match between the aerial image and DSM/DTM data for more accurate calculations. Apply filters to perform slope or surface analyses, quickly identify and differentiate ground or elevated features, and create output with desired object classifications, such as mapping solar panels or identifying objects between specific height parameters.
Smart City Planning with 3D Data
Creating a 3D digital representation of the earth can assist with smart urban planning as well as heritage conservation. DSM data can be used to solve challenges with urban development by generating 3D models of buildings, roads, and trees. Monuments or historical sites can be rendered for monitoring deterioration or development encroachment that could threaten preservation. Many GIS problems can be resolved with accurate DSM data.
Rolling Out 5G Networks with DSM
DSM data is helping transform the way network communications are being upgraded globally with 5G implementation. With the next generation of networks promising data speeds up to 50 times faster than 4G, 5G transmission demands shorter ranges between cell sites, a challenge in dense urban areas. Using DSM models of large cities, telecom companies can quickly identify where to install antennas with clear “lines of sight” between 5G sensors. This saves time and considerable cost for telecoms to identify these areas before sending out field operations teams to map the new network. They can create a plan that uses DSM data to identify what buildings or trees could impede a clear signal.
Bare Earth Data with DTM
Take out vegetation and built objects like trees and power lines with Digital Terrain Model data. Easily view height and elevation of the bare earth as well as natural features like rivers and ridge lines. DTM information can be paired with DSMs to derive information such as height in a given area. Other uses include soil mapping, flood or drainage modeling, land use studies and other geological applications.
