+        <p>
+            TeleSculptor is a cross-platform desktop application for photogrammetry.
+            It was designed with a focus on aerial video, such as video collected from
+            UAVs, and handles geospatial coordinates and can make use of metadata,
+            if available, from GPS and IMU sensors. However, the software can also work
+            with non-geospatial data and with collections of images instead of metadata.
+            TeleSculptor uses Structure-from-Motion techniques to estimate camera
+            parameters as well as a sparse set of 3D landmarks.
+            It uses Multiview Stereo techniques to estimate dense depth maps on key
+            frame and then fuses those depth maps into a consistent surface mesh which
+            can be colored from the source imagery.
