I am working on landscape quality maps using MapInfo. We embarked on a project to analyse the landscape, we plotted all our studies onto different tables divided in two different themes, Man made features and Natural features. These two themes were further subdivided under different headings such as built-up areas, waste-tips, fortifications, etc... for man-made features and afforested areas, SSSIs etc... for natural features. Each polygon identifying these areas was assigned a value representing the quality on a predefined scale.
The difficulty we are facing is to compute (adding up) the values of each polygon in the different tables geographically in order to have one map with all the values combined together. The methodology adopted was to create a grid made of 100m x 100m cells and we devised a program inhouse that will take points in these areas from the different tables and combine them together so we have a representative map. The only difficulty encountered is that the program works fine and the results are brilliant but it is time consuming. Approximately to compute one table it is taking around 33days!!!!!!!!!!!!!!!!!!!!!!!! with 31510 points in the grid, in total we have 10 tables and I don't wish to spend a whole year to produce a detailed "one" map!!!! Any form of help and ideas are very much appreciated!!!!!!!!!
