A map is prepared from a satellite image defined by digital data by integrating the image data with a digitised representation of geographical features within the map area and with text data defining textual material to appear in the finished product. This integration of data includes comparing each element of image data with an element or elements of feature data and replacing or modifying the element of image data as required to incorporate any feature or features defined by the element of feature data, and comparing the resulting combined image and feature data element with an element or elements of text data and replacing or modifying the combined data element as required to incorporate textual material defined by the element of text data. This integration of data may also include modification of the elements of integrated data in boundary regions surrounding features or text to provide a “burned-in”appearance in the finished product, as distinct from the appearance provided by overlay printing.

A method of making a map comprising the steps of: (a) processing data collected by remote-sensing to provide image data usable to define a pictorial representation of a selected region, said image data consisting of a multiplicity of elements of data, and each of said elements of data containing image information, (b) digitising a representation of geographical features within said selected region to provide feature data, said feature data consisting of a multiplicity of elements of data, and at least some of said elements of data containing feature-defining information, and (c) integrating said image data with said feature data to provide combined data usable to define a pictorial representation of said selected region, said combined data consisting of a multiplicity of elements of data, wherein said image data and feature data integrating step includes (i) establishing, for each element of image data, whether any corresponding element or elements of feature data exist, (ii) for any element of said image data to which no element of feature data corresponds, said any element providing an element of said combined data containing only image information, (iii) for each element of image data for which one or more corresponding elements of feature data exist, establishing for each of said one or more corresponding elements of feature data whether said each of said one or more corresponding elements of feature data contains feature-defining information, (iv) where said each of said one or more corresponding elements of feature data contains feature-defining information, said each of said one or more corresponding elements of feature data which contains feature-defining information providing an element of said combined data incorporating information pertaining to a feature or features defined by said each of said one or more corresponding elements of feature data which contains feature-defining information, and (v) where none of said one or more corresponding elements of feature data contains feature-defining information, said each element of image data providing an element of said combined data containing only image information.
