Abstract: A method for mapping a geographical location of a feature in a satellite image is provided. An image of a geographical surface is obtained, the image comprising a plurality of pixels, data indicating the latitude and longitude of each vertex of the image and data relating to a grid corresponding to the image is obtained. A grid location of a feature in the image is received, the grid location identifying a cell in the grid. The grid location is translated into a geographical location, which comprises calculating a pixel space location of at least one vertex of the identified grid cell; converting the pixel space into a latitude/longitude space based on the obtained data indicating the latitude and longitude of each vertex; and determining the latitude and longitude of the at least one vertex of the identified cell, based on the calculated pixel space location and the latitude/longitude space.
