Manipulations in Idrisi

Once all the necessary data had been obtained and imported into IDRISI, a number of further manipulations were undertaken in order to prepare the data for use in a multi-criteria evaluation using the Decision Wizard module. From the criteria put forward by Bloody Henriques the Englishman, four constraints and four factors were identified to be used in the evaluation.

Factors Constraints
Distance from areas of high population density Landuse classified as open/undeveloped or park/recreation
Distance from oceans and navigable rivers Areas not covered by water bodies
Distance from commercial areas Areas not covered by hard top road surface
Distance from liquor stores Areas of less than 3 degree slope

Macro models were made in IDRISI to generate images that represent the factors and constraints outlined above and to summarize the steps taken to produce the resulting images. Follow the links below to see macro models and resulting images for:
