Proximity to Water Bodies (Postal code metadata) - 2 - Proximity to Water Bodies (Postal code metadata) - 2

Hydrology files from DMTI Spatial Inc. CanMap Content Suite for 2018 (water bodies, water lines) were downloaded via the University of Victoria library, and loaded into a PostGRES database. Specifically for distance to oceans, we used the 2011 Hydrographic Layers - coast GIS file from Statistics Canada. Distances in metres to the nearest water feature within 5 kilometres by class (defined below) was calculated using PostGRES, for all DMTI Spatial Inc. single-link postal code for all years. This assumes that water features have remained constant over time. Note: many waterbodies in Alberta were coded as unknown in the water_defn column. Any features that were otherwise coded as permanent and had a river name or lake name were re-coded as watercourse and lake respectively and added to the appropriate class prior to calculation. NOTE: Features from the DMTI waterbody file are large enough to be representing as polygons or rivers/channels with right and left banks delineated. Features from the DMTI waterline file are narrow enough that they are only represented as a single line feature, rather than having a right and left bank.
