Title: General process description -- Description: The original databases are dynamically converted by a conversion (mediation) process operated by Natural Resources Canada (Groundwater Information Network). This process transforms the groundwater data transmitted via different formats for each data source into a standardized data structure defined by the GWML standard.

Depending on the structure of the source data and the units of measurement used, different transformations have been applied so that properties (attributes) and units of measurement are uniform throughout the resulting dataset. For example, source data expressing the thickness of geological layer intervals can be expressed as a stack, whereas the GWML standard prescribes a measurement taken at the top and base of each layer. The transformation applied therefore transforms the original stacked structure into a series of intervals. Although the data format is standardized, there are still disparities concerning the scope of attributes that are integrated for each data source, as each one meets an informational need that is specific to the jurisdiction that produced the source data.

The transformation of the data to create the Canadian Groundwater Well Dataset therefore offers a standardized view that is homogeneous in terms of structure and units of measurement for all the data available via this service. However, the extent of information content is not homogenized and is subject to provincial and territorial variations.

The original databases are dynamically converted by an automatic process managed by Natural Resources Canada (Groundwater Information Network).
