Regional Snowfall

Certain regions of B.C. are more prone to higher amounts of snowfall, which is ideal for this project. Since spatial or tabular data for snowfall depth in B.C. was not available, I did find a continuous image from the Atlas of Canada on the NRCan website to digitize in ArcMap. Digitizing occured with a B.C. basemap in the NAD 1983 UTM10n projection and UNION was used to create one shapefile of all the digitized regions. After a great deal of editing and clean-up, the shapefile was rasterized, tranfered into ASCII format and imported into IDRISI. In IDRISI, the image was reclassed to produce a Boolean image of areas that had suitable amounts of snowfall and those that did not. The macro model for snowfall is as follows:
