Yes, you can add any public-facing ArcGIS MapServer layer to Google maps. The MapServer tiles are called from javascript using the ESRI REST API. I am the developer of Gmap4 which is an enhanced Google map viewer. It can display up to ~24 user-specified ArcGIS MapServer layers. A click on the 'top' layer will display all the MapServer attribute data for the thing that you clicked. For maps that I have produced that can display MapServer layers, scroll down on this page: Public Land Maps With Clickable GIS Overlays For tips on using the map and the map legend, click "About this map" in the upper left corner of any map. For documentation on producing your own Gmap4 maps that display MapServer layers, start here: Gmap4 = Add ArcGIS Layers On Top of Google Maps November 19th edit: Gmap4 can now also display any user-specified ArcGIS ImageServer data. See the link immediately above for an example and the syntax. I will be updating all the rest of the documentation this winter. Joseph Elfelt Redmond, WA

A number of hurricane related layers are also available from NOAA and FEMA. See: nowcoast/wwa_meteocean_tropicalcyclones_trackintensityfcsts_time (MapServer) FEMA/Surge (MapServer)

For an all-javascript solution that converts between USNG and latlng, see the work by Larry Moore. Others worked on the code before Larry and they are credited in the js file. Start here: USNG Go to Larry's app and look at the source. usng.js is near the bottom of the source listing. I am using that code for point conversions in my Gmap4. Here is a 100m USNG grid with the map centered near the Seattle space needle. http://www.mappingsupport.com/p/gmap4.php?usng=10T_ET_4886_7428&tilt=off&z=17&t=h Joseph Elfelt Redmond, WA

I realize the REST API has a &transparent= parameter. But that is not the subject of my question. Instead, I would like to know what I can look at in REST metadata to easily tell if a layer was designed with a transparent background. For WMS metadata I look for opacity=0. What should I look for in REST metadata?

Evan, Since ESRI does not offer topos without shading, you might take a look at Gmap4 which has (1) variable shading on (2) very high resolution topos for the USA. (A small number of states are not quite ready yet.) This link opens Gmap4 showing a hi-res topo map centered on the Mt. Rushmore area: http://www.mappingsupport.com/p/gmap4.php?ll=43.880157,-103.454983&t=t4&z=15&hillshade=18 The default shading is a fairly light '18'. You can set the shading to zero either in the URL or by clicking Menu ==> Hill shading. Gmap4 is free for non-commercial use and there is a modest fee for commercial use. Note - The 't2 Topo Low' maps do not display anything since a few days ago Microsoft shut down the service that was supplying those maps. The next update to the Gmap4 code will have a replacement for those maps via "The National Map" (i.e. USGS). Joseph Elfelt, the Gmap4 guy Redmond, WA
