A cartographic model is a set of interacting, ordered map operations that act on raw data, as well as derived and intermediate data, to simulate a spatial decision making process (Tomlin 1990, in DeMers).
The purpose of the cartographic model is to chronicle our process in an organized manner. The cartographic model is simple, but requires a few clarifying details. Much of the initial data had to be manipulated. DMTI data originate as national themes, so they were scaled down to only contain Lower Mainland data. Then the data was projected into UTM (Universal Transverse Mercator) zone 10 for the study region. We used UTM zone 10 as opposed to BC Albers because the air photos were already in UTM zone 10. Using one projection for data simplifies the management of data.
