To display layer information:

  1. Click on and then on More information to open the GENERAL panel. Several information are presented there:

    • Number of layer features that are visible on the map. The number varies as you navigate the map.

    • Extent: X and Y indicate the position of the southwest point of the layer, width and height indicate the layer extent in meters from this point.

    • Metadata: information about the data in the layer such as quality indicators, the organization producing the data, update dates, etc. Metadata may be missing.

  2. The Transparency function, available for raster data layers, allows you to adjust the transparency level between 0% (default) and 100%.

  3. Click on the THEMATIC(S) and/or FILTER(S) tabs to display these panels.

  4. Click Back to return to the Layers panel.
