Here's a visual of what I'm trying to do: http://imgur.com/m3ijxVI.jpg Basically I'd like the "multiple ring buffer" tool to treat polygon #3 as an 'impassable barrier' so the distance between polygon #1 and #2 excludes the possibility of crossing into the #3. Is this possible? I have ArcMap 10.2 with several extensions including spatial analyst. Thanks for any help!

I see. Thank you. But when I put in my shapefile I want my raster to be clipped to I get a blank output. I guess this only works for rectangle polygons and if I want my output raster to have the same shape as a non-rectangle polygon (based on a shapefile as a bounding input) the only way to do that is to clip it once it's made? Someone else said that I could 'Extent' to define the shape of my output raster, but I didn't think that was the case, just the highest north south east west points.

I only have 'Processing Extent' which does not do what I need, which is to limit the extent of the output file from the "LAS Dataset to Raster" tool. The Tool help from http://resources.arcgis.com/en/help/main/10.2/0012/001200000052000000.htm says that 'Extent' should be between Workspace and Output Coordinates but as you can see it is not. What can I do?

Thank you for the reply. That sounds like it would work, but again I just want the z values calculated in the existing dataset, no temp files or output files. I guess it's impossible, save for using the 3D Analyst Toolbar 'Interpolate' for every feature I create. I'm trying to streamline a very large data collection workflow.

That's disappointing! Thanks for the reply

> it is most unlikely that you can if the featureclass has not yet the Z values enabled. Z Values are enabled for my feature classes! Shape field has a value of 'Polyline Z'. >If the featureclass has Z values enabled on creation but you do not set them initially, you can update the Z values without creating a new output (although this would require some scripting). This is what I need to do. Is there any more information on this method?

It may have something to do with the 'Void Fill' settings in the tool? If so, which setting would fix this? Or maybe this from ESRI's LAS Dataset to Raster tool help: "Including a study area boundary as a clip constraint in the definition of the input LAS dataset is highly recommended. One reason is to prevent interpolation from occurring outside the real data extent of the survey." If it's this, how do I make a clip constraint in the LAS Dataset?

Thank you, I've moved it to 3D!

Is there way to do what the 'Interpolate Shape' tool does but calculates the z values into the Shape field of the input feature instead of making a new output? As far as I can tell the only other way is by using the 3D Analyst toolbar and selecting the 'Interpolate' tool based on the geometry I need but I'd rather not have to click that every time I digitize something but would prefer to do it after all my features at once after they're created. 'Interpolate Shape' does that but makes a separate file, which does not fit into my workflow. Is there another way? Perhaps using the Field Calculator?

When I run the 'LAS Dataset to Raster' tool, my raster always has these stretched/stitched areas outside the tiles. How can I fix this beyond just clipping the raster afterward?
