Map Features

Feature Layers vs Tile Layers

  • Feature layers support vector feature querying, visualization, and editing. Feature layers are most appropriate for visualizing data on top of your basemaps. In web apps, feature layers are drawn by the browser and support interactive highlighting, queries, and pop-ups. Tile layers support fast map visualization using a collection of predrawn map images, or tiles. Tile layers are appropriate for basemaps that give your maps geographic context.

  • [Administrative limits]  Communes_2013 - Feature layer
  • Swisstopo data sets are available as online services. They are published in Swiss projection so you cannot add them to a standard web Mercator online basemap. Instead, you need to add an image service from Swisstopo as a basemap and then add on top other layers you may be interested in:

    1. Open the Map Viewer > Add Layer from Web > A WMTS OGC Service > Enter the URL https://wmts.geo.admin.ch > Choose a basemap layer like “National Map 1:25’000” and enable the checkbox “Use as Basemap”.

    2. Repeat the same process to add operational layers to your map, but don’t check “Use as Basemap”.

    3. To find the legends for the various layers explore map.geo.admin.ch.

  • All the layers available on map.geo.admin.ch can be added > Add Layer from Web > A WMS OGC Web Service > Enter the URL https://wms.geo.admin.ch [the list is in German].
