Title: General process description - AFSOQ -- Description: The dataset was extracted from the raster afsoq_drastic file from the project AFSOQ archives folder.

The data set was produced using the data that was used to produce the following article:

MURAT, Valérie, RIVERA, Alfonso, POULIOT, Jacynthe, et al. Aquifer vulnerability mapping and GIS: a proposal to monitor uncertainty associated with spatial data processing. Geofísica internacional, 2004, vol. 43, no 4, p. 551-565.

Title: General process description - Annapolis - bedrock -- Description: The dataset was extracted form the file bg_gsc_v_Erase.shp that was converted to a raster using ArcGIS by attributing the values in the field GRIDCODE to pixels. The cell length is 100 m. Pixels values correspond to the fallowing values.

1. 1-79 Extremely low;

2. 80-99 Very low;

3. 100-119 Low;

4. 120-139 Moderate;

5. 140-159 Moderately high;

6. 160-179 High.

Title: General process description - Credit River -- Description: The dataset comes from the vulnerabilite_credit.png file of the Credit River archives folder that was georeferenced in ArcGIS. Georeferencing was approximate because the image did not have elements that could easily be georenferenced. A polygonal type dataset was manually created by outlining the vulnerability zones over the georeferenced image. The dataset was then converted to a raster using ArcGIS. The cells length was set to 50 m which almost corresponds to the map's resolution in (.png.) Pixels values correspond to the vulnerability level as follow:

1. Low;

2. Variable;

3. Mainly High.

Title: General process description - Carboniferous basin -- Description: The dataset comes from the file geol_vuln.shp of the MGWI project archives folder. The file was converted to a raster by attributing the values of the field champ VULN to the pixels. Pixels values represent the vulnerability values:

1 : Low;

2 : Moderate;

3 : High.

Title: General process description - Annapolis - surficial deposits -- Description: The dataset was extracted form the file sg_gsc_v_Erase.shp of the Annapolis project archives folder. the data was converted to a raster using ArcGIS by attributing the values in the field GRIDCODE to pixels. The cell length is 100 m. Pixels values correspond to the fallowing values.

1. 1-79 Extremely low;

2. 80-99 Very low;

3. 100-119 Low;

4. 120-139 Moderate;

5. 140-159 Moderately high;

6. 160-179 High.
