Digital Surface Model Results

With a Professional Subscription to FarmLens, you can export Digital Surface Models (DSMs) that are generated from your drone imagery.

DSMs and derivative products are useful for providing an overview of terrain features in your fields.  Here's an example of a Shaded Relief product derived from a DSM where features like furrows are clearly visible.

At times, we see that exported DSM models from FarmLens include inaccuracies caused by the camera or flight setup.  One common artifact is "DSM cupping" caused by inaccurate lens calibration.  In these cases, especially noticeable when there's very little topographic variation in a field, the cupping artifact can be seen in the false color DSM.  If your results show a pronounced pattern like this on a field you know to be flat, trust your on-the-ground knowledge.

Here's an example from the same field.
