Open Data
To aid in transparency & decision-making, RVCA is working towards freely-downloadable and open, online-access to key datasets, information & mapping. We are currently developing in JKAN. A light-weight, user-friendly, open source data portal available on GitHub. We will be rolling out datasets one-by-one, when available, each with an associated licence and metadata.

By downloading the data, you agree to the terms of the associated licence. We continue to review our data and licensing approach and are committed to providing access to more data and web maps & services. |
Web Mapping Services
The RVCA's web mapping services are available to consume in GIS (ie ArcGIS Desktop or ArcGIS Online) or your own interactive web maps. The map services can be found one of two ways. From our REST endpoint or via ArcGIS Online. Please follow the instructions below to access our data. For a full description of the ArcGIS REST API, please visit resources.arcgis.com
- REST endpoint: Contains web mapping services used in the various RVCA GeoPortals, including Hazards & Regulation Mapping, Monitoring/Gauges, Drinking Water Source Protection, Hydrology, Conservation Areas, Landcover & Natural Features, Political, Imagery and Topography (Terrain)
- RVCA ArcGIS Online: Contains all the web mapping services listed above via our REST endpoint, but accessible from ArcGIS Online. Open RVCA ArcGIS Online Map and then login or click Modify Map in the top-right corner. Click the Add button and then Search for Layers. All the publicly available RVCA layers should appear and be available to add to the map. If not, search ArcGIS Online and in the Find textbox type RVCA and browse for all services published by RVCA_GIS.
Services can be readily consumed from the REST endpoint in ArcGIS Desktop by following the instructions below:

Looking for RVCA Subwatershed and Catchment Reports? watersheds.rvca.ca
The RVCA produces individual reports on the Rideau watershed’s catchments. These catchment reports are a compilation of data collected through the RVCA’s watershed monitoring and land cover classification programs. Catchment information is used to develop subwatershed reports that summarize the health of the Rideau’s six main subwatersheds.
