Measure Building Height From Satellite Imagery Using ArcGIS Desktop

Measure building height is not something easy to do in the field. You going to needs field equipment that is not always easy to carry around. On another occasion may be you needs Digital elevation surface data to helps you correctly measure building height. Even you going to needs finer resolution DSM that so expensive and hard to find. Is there any other way if you want to know building height in very easy way. 

Lucky for you, ArcGIS Desktop has been implemented a measurement tool that is not only works in 2D space, but also in 3D space. The tool is called Mensuration Tool. It can measure point, line or polygon in 3D, so you will get Z-dimension information like height or elevation from a source data. Currently it could measure building height from high resolution satellite imagery in an intuitive way. By intuitive I means its precision of measurement will highly depends on how you do the measurement. You can directly measure house or building height using its shadow as reference, or you can directly measure it from the top to bottom level of the building. What you needs is just a high resolution satellite imagery that accompanied by its original metadata from the vendor. It is also must have RPC information stored in the metadata or provided as separated file. As long as ArcGIS could properly read the metadata, you are good to go. If you are curious about how to do it, below is a video tutorial about how to do it in ArcGIS Dekstop ArcMap.
