The purpose of a map is to represent the earth's surface so that you can measure dimensions, directions, areas, etc, as opposed to using aerial photographs that have distortions. An orthophoto (a geometrically correct aerial image map) was created from a single aerial image captured with an unmanned aerial vehicle (drone).

The drone image has a very high resolution as compared to the satellite image. Imagine if we could use this data to directly measure dimensions from an image. This is exactly what we did.
Once the aerial image was processed and converted into an orthophoto, the orthophoto was overlaid onto the satellite image and we found excellent results when measuring the dimensions. According to the institution, the size of the ground is 100m x 68m which we have measured with centimetre accuracy using our orthomosaic map. You can see it below.
