Hydrography (HY) Iceland is one of 12 themes in the European Location Project (ELF). The purpose of ELF is to create harmonised cross-border, cross-theme and cross-resolution pan-European reference data from national contributions. The goal is to provide INSPIRE-compliant data for Europe. A description of the ELF (European Location Project) is here: http://www.elfproject.eu/content/overview Encoding: INSPIRE version 4

Point features showing the location of groundwater wells in BC joined with attributes and information from the Groundwater Wells and Aquifers (GWELLS) application. NOTE: Artesian wells are flowing wells at the time of drilling. Suggested Filters: - Groundwater Supply Wells - Intended Water Use: WELL_CLASS = 'Water Supply' - Provincial Observation Wells: OBSERVATION_WELL_STATUS = 'Active' OR OBSERVATION_WELL_STATUS = 'Inactive'

Flood extent polygons from the current calendar year in selected Canadian regions that have been designated for observation, monitored by Natural Resources Canada using satellite imagery for emergency response. Coverage is not comprehensive nationwide. In response to large flood events, Natural Resources Canada (NRCan), for the provision of emergency geomatics services, may be activated by Canada’s emergency management protocols. As new satellite imagery becomes available, NRCan will extract flood extent polygons and update the dataset in near real time (4 hours). This item contains the flood products generated in the past year. For any data relating to previous years, please refer to the [Floods in Canada – Archive]( https://open.canada.ca/data/en/dataset/74144824-206e-4cea-9fb9-72925a128189) entry. Please note that the web mapping service may not display data if flood polygons have not been published by the EGS for the current year. The flood products generated are validated on a best effort basis. Various factors may affect the quality of the flood polygons. These factors include, but are not limited to, sensor type, image resolution, cloud cover or limitations of the flood polygon extraction method. In this layer, where possible, a symbology is applied to the flood polygons based on the underlying land use classification, or is simply unclassified and shows the raw flood extent. When using Web mapping services, to display a specific product, filter by date (UTC Date) and area of interest (AOI). Also, a link to download each product is available in the Resources section. This prepackaged and compressed product contains a Shape file, a PDF file and a KMZ file. Disclaimer : Emergency response authorities are the primary users of these satellite-derived open water flood extent map products. These products are generated to provide analysis and emergency response situational awareness and to facilitate decision-making during major flood events. The open water flood extent products are generated rapidly and limited time is available for editing and validation. The flood products reflect the open water flood conditions at the date/time of acquisition. While efforts are made to produce high quality products, near-real time products may contain errors due to the limited time available for vector editing and validation. Please note that current algorithms do not map flooded areas under the forest canopy and are not optimized for urban flood mapping.

The "Total Effective Drainage Areas of the AAFC Watersheds Project – 2013” dataset is a geospatial data layer containing polygon features representing the areas within the “total gross drainage areas” of each hydrometric gauging station of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project that would contribute to average runoff. A ‘total gross drainage area’ is the maximum area that could contribute runoff for a single gauging station – the ‘total effective drainage areas’ are those parts of that ‘total gross drainage area’ that would contribute surface runoff to an average runoff. For each “total gross drainage area” there can be only one “total effective drainage areas”. These polygons may overlap with those from other gauging stations’ “total gross drainage area”, as upstream land surfaces form part of multiple downstream gauging stations’ “total gross drainage areas”.

The “Hydrometric Gauging Station Network of the AAFC Watersheds Project - 2013” dataset is a geospatial data layer containing network line features representing links between hydrometric gauging stations of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. Each line connects a gauging station to its downstream neighbour(s), indicating its drainage direction. This network is a ‘drainage’ network, not a ‘stream’ network. That is, the lines do not in any way portray the actual stream path between stations. In some instances, a lake, for example, an area may have several gauging stations. In such cases, one of the gauging stations is designated the ‘primary’ gauging station for calculation purposes, and to maintain proper hydraulic relationships between gauging stations, where only the primary stations are connected to the downstream portion of the network.
