There is provided a method for mapping a geographical location of a feature in a satellite image. The method comprises obtaining an image of a geographical surface, wherein the image comprises a plurality of pixels obtaining data indicating the latitude and longitude of each vertex of the image; obtaining data relating to a grid corresponding to the image; receiving a grid location of a feature in the image, wherein the grid location identifies a particular grid cell in the grid; and translating the grid location into a geographical location. Translating the grid location into a geographical location comprises calculating a pixel space location of at least one vertex of the identified grid cell; converting the pixel space of the image into a latitude/longitude space based on the obtained data indicating the latitude and longitude of each vertex of the image; and determining the latitude and longitude of the at least one vertex of the identified grid cell, based on the calculated pixel space location and the latitude/longitude space output by the converting. |
