Hi list,
I'm looking at trying to set up an OpenLayer3 demo using the UTFGrid
format provided by MapServer.
http://mapserver.org/development/rfc/ms-rfc-93.html#rfc93
http://mapserver.org/output/utfgrid_output.html
As luck would have it, it appears OpenLayers2 actually has a better
implementation on the client-side. See links:
http://dev.openlayers.org/examples/utfgrid.html
http://dev.openlayers.org/docs/files/OpenLayers/Layer/UTFGrid-js.html
OL3 seems to require a server-side component to return a callback with
details on the service. Even if I set this up, it expects the UTFGrid
service to use a tile grid format ({x}{y}{z}).
http://openlayers.org/en/v3.14.2/examples/tileutfgrid.html
I can configure MapServer to return UTFGrids using WMS GetMap requests
(as stated in the RFC), but not when using the tile mode -
http://mapserver.org/output/tile_mode.html
I can probably hack together a workaround to work out tile numbers from
BBOXes, but I was wondering if I'm missing something simple to get this
to work directly.
Has anyone manged to set this up?
Thanks for any advice,
Seth
