Drawing route under road

Post by Patricia »

Hello,
How can I paint the route that we get after a routing under the roads and streets layer using the routing web service?
Attached there is a screenshot of the local mapserver version 5.3 with wich this was the default paint method for routes that we get after routing.
Thanks

Hello Patricia,

in fact xMapServer only provides two basmap-layers: "background" and "labels". If yout want to add additional client-content, like an xRoute polyline, you can either add it topmost or between background and labels.

With xMapServer you cannot interlay content as fine-grained as with MapServer. This is a technical restriction due to the web technology involved. A solution to display routes for xMapServer is to render them between background and labels, but setting the route semi-opaque, so you can also see the underlying road.

We are planning to support this specific use case by introducing a 3-layered base map (background-transport-labels) in the future.
