CanSIPS data available on MSC GeoMet

MSC GeoMet provides access to data produced by the Canadian Seasonal to Inter-annual Prediction System (CanSIPS) model. Users can build mobile apps, create interactive web maps, and display layers in desktop software.

Access to the geospatial web services

The CanSIPS datas are available on GeoMet-Weather via the Web Map Service (WMS) and Web Coverage Service (WCS) standards.

Example of a web map configured to display the probability of temperature above normal for the first three months of the associated CanSIPS forecast (CanSIPS_100km_AirTemp-ProbAboveNormal-2m_P00M-P02M) served by MSC GeoMet:

Usage

The usage overview page provides generic information on using OGC services with desktop software, mobile apps, interactive web maps and direct access. Please refer to the tutorials and technical documentation for MSC GeoMet geospatial web services for detailed information.

Available layers

For details of the CanSIPS layers served by SMC GeoMet, see the WMS GetCapabilities document.

Desktop GIS software such as QGIS also makes it easy to navigate the WMS GetCapabilities document as a layer tree.

Usage tips

Retrieving the available model runs and forecast hours available for a given CanSIPS layer:

• Users can use the layer query parameter in WMS GetCapabilities requests to point to a specific layer and retrieve a smaller XML payload with up-to-date temporal dimensions (see the <Dimension> tags). Example: https://geo.weather.gc.ca/geomet?service=WMS&version=1.3.0&request=GetCapabilities&layer=CanSIPS_100km_AirTemp-ProbAboveNormal-2m_P00M-P02M
• Additional information is available in the handling time with WMS section

WMS styles:

• In addition to the default WMS style, several alternative WMS styles with different color scales are available. The list of available WMS styles is provided in the WMS GetCapabilities response.
• Furthermore, users can request layers with their own custom styles with the Styled Layer Descriptor (SLD) standard, please refer to the SLD technical documentation.

Legends:

• Legends are available for every WMS style. Details are provided in the WMS legend technical documentation.
• Example of retrieving a layer's legend via a GetLegendGraphic request: https://geo.weather.gc.ca/geomet?version=1.3.0&service=WMS&request=GetLegendGraphic&sld_version=1.1.0&layer=CanSIPS_100km_AirTemp-ProbAboveNormal-2m_P00M-P02M&format=image/png&STYLE=AirTemp-ProbAboveNormal_40-100Pct_Dis.
