Things

Images contain information not easily seen with standard photographic techniques and equipment.  On a large scale, a builder, architect, realtor or home owner may be interested in a property's overall layout and composition.  On a slightly smaller scale, high precision scans of  interiors and products are essential for remodeling, reconstruction, production, and restoration.

The image below is a 35 acre area taken from Google Maps.  While it's useful to get a general idea of how the property is laid out, it doesn't provide a lot of detail.

The second image is the same area as the first image, but shows the relative height of the terrain.  It's created with an aerial drone equipped with a LIDAR sensor that senses the ground under the tree canopy.  Notice the small creek on the right side of the image that's invisible in the original photograph.  Accuracy is within a few centimeters.

The third image shows the relative grade of the terrain.  Lighter colors indicate a steeper grade.

Finally, a fully digital movie of the entire property.  It begins with a complete orbit of the property if different modes:  photographic data, height encoded data, digital elevation map, and digital elevation with contour lines.  The contour lines were arbitrarily set to 2 meters.
