Abstract
To be precisely extracted a house footprint. There is provided a geospatial information creating system for extracting a footprint of a house from an aerial photograph, comprising a processor for executing a program, a memory for storing data required for executing the program, and a storage unit for storing the aerial photograph. The processor detects edges of an image based on a characteristic quantity of neighboring pixels in the aerial photograph stored in the storage unit; extracts an orientation of the house by analyzing directions of the detected edges; and generates a polygon of an outline of the house by using linear lines of the extracted orientation of the house.
