Topoquest tile URL Please Help

Postby graydon » Mon Mar 12, 2012 10:36 am

I am in search of obtaining a map tile code URL for my GIS APP. I was hoping that topoquest could fulfill my needs. Here is what the are examples of the links that work for my different map types;
Example 1 http://mt#SN#.google.com/vt/lyrs=t@128,r@169&hl=en&x=#X#&y=#Y#&z=#Z#&s=#GL#
Example 2 <http://services.arcgisonline.com/ArcGIS/rest/services/USA_Topo_Maps/MapServer/tile/#Z#/#Y#/#X#
Does anyone know how to create a link like these to make topoquest function as my topo map source? Any help would be appreciated. :D

Hello,

At the moment, there isn't a way to use TopoQuest as a tile service. For that to work, all the map data needs to be reprojected to a Mercator projection and sliced up into tiles in a standard file naming scheme. The TopoQuest map data is stored in the original UTM projection that the USGS publishes the maps in. I've been kicking around some experiments in converting all the TopoQuest maps to Mercator-projected tiles and brewing up a user interface that is a little more like people are used to (i.e. click and drag the map on-screen, like Google Maps). At that point it may be possible to devise a method for using the tiles by third-party apps, we'll see.

Cheers,
-Ryan
