Examples with Envelope2D org.geotools.geometry.Envelope2D used on opensource projects

Example 1 with Envelope2D

use of org.geotools.geometry.Envelope2D in project OpenTripPlanner by opentripplanner.

the class TileService method tileGet.

@GET
@Produces("image/*")
public Response tileGet() throws Exception {
    Envelope2D env = SlippyTile.tile2Envelope(x, y, z);
    TileRequest tileRequest = new TileRequest(env, 256, 256);
    RoutingRequest sptRequestA = buildRequest();
    Layer layer = layers.get(0);
    Style style = styles.get(0);
    RenderRequest renderRequest = new RenderRequest(format, layer, style, true, false);
    Router router = otpServer.getRouter(routerId);
    // router.renderer.getResponse(tileRequest, sptRequestA, sptRequestB, renderRequest);
    return null;
}

Example 2 with Envelope2D

use of org.geotools.geometry.Envelope2D in project OpenTripPlanner by opentripplanner.

the class SurfaceResource method differenceTileGet.

/**
 * Renders a raster tile for showing the difference between two TimeSurfaces.
 * This service is included as a way to provide difference tiles using existing mechanisms in OTP.
 * TODO However, there is some room for debate around how differences are expressed in URLs.
 * We may want a more general purpose mechanism for combining time surfaces.
 * For example you could make a web service request to create a time surface A-B or A+B, and the server would give
 * you an ID for that surface, and then you could use that ID anywhere a surface ID is required. Perhaps internally
 * there would be some sort of DifferenceTimeSurface subclass that could just drop in anywhere TimeSurface is used.
 * This approach would be more stateful but more flexible.

 * @param surfaceId The id of the first surface
