Display Base Topographic Map in Feet (not Meters)

[RayJulich]

I have a map (http://wa.water.usgs.gov/projects/puyallupmonitoring/hydrographs.htm) that uses the ESRI topographic base map (http://server.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer). The elevations listed on the map are in meters, but the information in all the infoWindows on my map are in feet. Is there another version of the topographic base map that I can use which has the elevations listed in feet?

I get an error when loading the url you provided regarding trouble parsing Hgraph.csv, so I wasn't able to test your app, but you should be able to multiply the number returned by the service by 3.28084 to convert to feet in your popup.

Sorry that my expanation was unclear. The units in my popup window are in feet. The basemap displays elevation in meters. I would like for the basemap to display elevations in feet. I will fix the web page on Monday so that you can see the basemap. I know what the problem is - it's an easy fix. If you go to the URL that I refer to for the basemap is http://server.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer. In the documentation on that page, it says that one of the layers is elevation (ft).

If you would like to take a look at a web page with a basemap, look at http://wa.water.usgs.gov/projects/yakimagw/hydrographs.htm. The page doesn't work correctly, but the basemap is there. You will be able to see on the page that the evelations are shown in meters.

ah.  NOW i understand what you're going for... 🙂

unfortunately the layers listed in the cached map service are used to support identify requests to the service and not the actual layers displayed in the cartography.  i'm not the definitive source for information on this, but i think we exclusively use meters in our 'world'  topographic basemap.  As an alternative, you might consider using something like our USA topo service (based on USGS topos) instead.
