Title: General process description - Annapolis -- Description: The dataset was extracted from the file bedGeol.shp of the Annapolis project archives folder. The data regarding the geological units were found int the Hydrogeological Atlas of the Annapolis Valley produced by the Geological Survey of Canada.

Bedrock geological units were assigned a lithologic class based on the dominant composition, with the understanding that some units are too complex to be assigned a single lithologic class, in order to render the map in a uniform national map. The original classification of the unit is still available in the dataset, along with a link to the Lexicon of Canadian Geologic Units (http://weblex.nrcan.gc.ca/). The GeoSciML / IUGS lithological classification has been used as a standard earth material vocabulary (http://resource.geosciml.org/).

Title: General process description - Mauricie -- Description: The dataset comes from the Geologie_du_socled file of the MAUR_UQTR.gdb geodatabase. The geological units descriptions were found in the attribute table of the file and in table 4.1 of the final report for the project ''caractérisation hydrogéologique du sud-ouest de la Mauricie'' that was submitted to the Ministère du Développement durable, de l'Environnement et des Parcs.

Bedrock geological units were assigned a lithologic class based on the dominant composition to the extent it was possible, with the understanding that some units are too complex to be assigned a single lithologic class, in order to render the map in a uniform national map. The original classification of the unit is still available in the dataset, along with a link to the Lexicon of Canadian Geologic Units (http://weblex.nrcan.gc.ca/).

Title: General process description - Paskapoo -- Description: The dataset comes from the GW_TEST.BDR_Fm_AB file of the CAL_TEST - GW test - RO.sde geodatabase. The dataset was cut using ArcGIS to show only the studied area of the Paskapoo unit (limites_paskapoo.shp). The data regarding the units description is form the Lexicon of Canadian Geological Names.

Title: General process description - Oak Ridges Moraine -- Description: The dataset (Bedrock Geology MRD126-REV1.zip) was downloaded from the Ministry of Northern Development and Mines site (http://www.mndm.gov.on.ca/en/mines-and-minerals/applications/ogsearth). The geopoly.shp file was cut using ArcGIS to keep only the data related to the studied area (limites_orm.shp).

Title: General process description - Gulf Islands -- Description: The dataset comes from the GW_Test.BDR_Fm_BC file of the CAL_TEST-GW Test-RO.sde database. The dataset was cut in ArcGIS using the gulf_islands_limits.shp file. The mame, des_en and unit_code fields correspond to the STRAT_NAME, ORIGINAL_D and STRAT_UNIT fields of the original file.

Title: General process description - Chaudiere -- Description: The dataset comes from the synth_geologie_rocDD_nad83_clip1.shp file of the Chaudière River Watershed project archives folder. The geological units name dataset was created by merging the MON_GRP and MON_FRM fields. The English descriptions are from the lexicon of Canadian Geologic Units and the french from the Lexique stratigraphique canadien d'Yvon Globensky (1993) or from the file itself.
