A system, apparatus, computer program product, and method use a convolutional neural network to auto-determine a first floor height (FFH) and a FFH elevation (FFE) of a building. The FFH, and FFE of the building are determined with respect to the terrain or surface of the parcel of land on which the building is located. In turn, by knowing the FFH and/or FFE of the building on the parcel, it is possible to use that information while performing a flood risk assessment to a property without requiring a personal inspection of the parcel by a human.

A technique for enabling efficient surveying operation that uses a light-reflecting target is provided. A surveying apparatus is configured to survey a reflecting prism and includes a controller, a surface calculator, and a position calculator. The controller performs positioning on three or more points on the set-up surface on which the reflecting prism is set up, by using laser light.
