Matthew, Try using Extract by Mask instead of Clip Raster. Another approach to try to is use the Extent Environment in your Resample to avoid the need to clip.

Hi Kristen, We base our SSURGO derived imagery layers on the gSSURGO 30m raster. NRCS also produces a 10m raster that is included with gSSURGO. We originally published these layers before gSSURGO was available and made our own rasters at 30m to match our other services like NLCD and NED that were typically 30m. We would consider publishing the layers using the 10m gSSURGO raster if there is a good use case for it. My understanding is that the 10m was primarily designed for cartography while the 30m better captures the data collection scale.

Patrick, One nice feature of GIS services is that you eliminate the download step. Its a different way of thinking about GIS but a very powerful way of doing things. Go to the content item (the ArcGIS.com webpage) for terrain and click the blue drop down box that says "Open" and the select "Open in ArcGIS for Desktop". Your browser will save a file called item.pitem to your default downloads folder. Double click that file to open in desktop. From there the service will behave just like data on your disk. You can use it as an input to Geoprocessing Tools, Model Builder, or Python Scripts. If you really want a local copy you could run the clip tool or export the data to a new raster. There is an area limit and i can't remember it right now but it should work. The 30 m Africa data was just recently released by the USGS and NGA so it should be the best available. RN

You can try the Esri Terrain Service (http://www.arcgis.com/home/item.html?id=58a541efc59545e6b7137f961d7de883 ). We just updated it with 30 meter data for Africa. Rich Nauman

In addition to all these great tips, I recommend not re-sizing the thumbnail image.

I am interested in hearing how users are incorporating the Living Atlas resources into their work. We are currently in the process of updating several of the natural resource layers so any feed back we can get will be useful as we build out these services.

Depending on what SSURGO fields you need you may be able to use the soil layers available through the Landscape Layers group in ArcGIS.com.

Yes, You can use the clip tool to extract sections of the landscape image services. There are size limits that you should be aware of that are documented in the arcgis.com content item for each service. You can download sections of the vector data using the Extract Landscape Source Data Tool.

Esri now provides SSURGO Hydrologic Soil Group as an image service. You can use this service ArcGIS online or ArcGIS Desktop for visualization and as an input to geoprocessing tools.

Stephanie, If you have a feature class containing multiple polygon features that you want to use as inputs to the Extract Landscape Source Data tool you can use model builder and loop through each polygon in the feature class using a Feature Selection Iterator. When you run the model it will extract and download data for each polygon in your feature class. A simple model to do this looks like this: [ATTACH=CONFIG]29065[/ATTACH]

It would be useful to be able to sort arcgis.com search results by extent. Often search results return many local data sets that are derived from some larger dataset - by sorting on extent a user could find the comprehensive datasets quickly. This will become more important as the number of datasets stopred in arcgis.com grows.

Thanks for the help!!! I'm not sure where I went off track but the following works: import arcpy
raster = r"c:\GIS_Data\some_raster"
outraster = r"c:\GIS_Data\delete_me"
desc = arcpy.Describe(r"c:\GIS_Data\test_extent2.shp")
frame = str(desc.extent)
arcpy.Clip_management (raster, frame, outraster)
print "Done!"

Thanks for the help but I am still struggling. This script works: import arcpy raster = r"Y:\GIS_Data\raster1" outraster = r"Y:\GIS_Data\delete_me" desc = arcpy.Describe(r"Y:\GIS_Data\test_extent2.shp") frame = str(desc.extent) frame = str(frame [:-16]) frame = str('"' + frame + '"') print frame arcpy.Clip_management (raster, "-121.677618762735 42.7497214280392 -119.35205017646 45.3659860875993", outraster) print "Done!" But this one does not: import arcpy raster = r"Y:\GIS_Data\raster1" outraster = r"Y:\GIS_Data\delete_me" desc = arcpy.Describe(r"Y:\GIS_Data\test_extent2.shp") frame = str(desc.extent) frame = str(frame [:-16]) frame = str('"' + frame + '"') print frame arcpy.Clip_management (raster,frame, outraster) print "Done!" I copied and posted the output from the "print frame" statement into the clip statement to get it to work. Any ideas?
