NEW: Digital Surface Model API Now Available


No longer do you need to wait for hours on end to download massive GeoTIFF files for your DSM data. Vexcel just launched a new API providing easier—and quicker—access to its 7.5cm resolution Digital Surface Model data.

DSM—Why It’s Useful

Digital Surface Model data helps you understand and better visualize what exists on the earth’s surface. This valuable information is used to extract data to better predict flood modeling, evaluate man-made objects on all types of property, and improve risk analysis and assessments.

What You Get

The new API provides standard 256 x 256 tiles in GeoTIFF format, conforming to WMTS spec requirements so the data aligns perfectly with other types of Vexcel content, including true orthos and near-infrared tiles. This allows you to avoid any painful up/down sampling or need to transform data when matching DSM to Vexcel’s superior imagery.

You can see a quick example of how perfectly every pixel is read from the GeoTIFF file below as compared to the ortho.

How to Get Started

To begin accessing DSM data via the API, follow the simple instructions included in the API documentation here. You can quickly render or display data in a variety of platforms whether you’re familiar with DSM data or not. Additional information can also be found here on my technical blog.
