Here is the help on how to drape a raster on a custom surface. ... View more

I would recommend the Contour with Barriers tool to specify the option to generate index contours.  This will add a field to the contour file.  Then you can actually see the fields with the different contours. ... View more

Can you post your syntax for the raster calculator input? ... View more

It appears from your message that there appears to be an issue with your license if you are receiving the license message. In terms of your other error, usually multipoint files are created in a feature dataset within a geodatabase.  I would recommend making the output a feature dataset within a geodatabase. ...

What happens if you change the value?  Can you see the radius being recognized at all?  What about if you run it outside of the model will it work correctly? Also if you are desiring the surrounding 500 feet, you might need to change since you have meters in the data frame. ... View more

There are the following stats that can be added: Z �??Surface elevation interpolated for the XY location of each single-point feature. Z_MIN �??Lowest surface elevation in the area defined by the polygon, along the length of a line, or among the interpolated values for points in a multipoint record. Z_MAX �??Highest surface elevation in the area defined by the polygon, along the length of a line, or among the interpolated values for points in a multipoint record. Z_MEAN �??Average surface elevation of the area defined by the polygon, along the length of a line, or among the interpolated values for points in a multipoint record. SURFACE_AREA �??3D surface area for the region defined by each polygon. SURFACE_LENGTH �??3D distance of the line along the surface. MIN_SLOPE �??Slope value closest to zero along the line or within the area defined by the polygon. MAX_SLOPE �??Highest slope value along the line or within the area defined by the polygon. AVG_SLOPE �??Average slope value along the line or within the area defined by the polygon. The 'Add Value' button does not appear to have an effect and is not listed in the help as being active.  If you would like additional ones added to this list, then I would suggest making that an 'idea' on the ArcGIS Ideas page.  With enough support, the enhancement could possibly be considered. ...

The z units are most likely meters and your UTM should also be meters, unless they have been modified. Have you tried ground truthing against known elevations like benchmarks?  As long as the units are the same you should be fine and a z factor will not be necessary. If you have feet elevations then the issue will still occur. ... View more

You can resample the raster DEM or DSM to achieve the different cell resolutions, but in terms of mixing them I am not sure how.  When you look at any raster there is one cell size for it, so I am not sure what you are looking to achieve. Perhaps you could burn in the DSM that is coarser into the DEM if that is the case, that way the finer resolution can account for the coarser.  In this case the larger features can be made up of smaller cells of the finer resolution. ...

Consider the use of inline variables to modify and harvest the name of the raster.  Perhaps using the Calculate Value tool in Model Builder to modify it if necessary. ... View more

Depends on your 'conversion' step, if you wanted to put them all together, you could have simply used the mosaic to new raster or depending on your version of ArcMap use a Mosaic Dataset.  If the 'conversion' did not involve the Copy Raster tool or export, then you might have invalidated the rasters in the process.  If you want more specific help, then  I recommend contacting Esri Support. ...

Is the point cloud covering nodata values or do the coordinate systems match?  Could there be points where no raster data could possibly be? ... View more

Try any of the volumetric solutions that 3d Analyst offers, from Cut/Fill, Surface Volume or even Polygon Volume. ... View more

You could try Raster Painting under ArcScan.  That can let you change the values of specific cells manually. For more automated processing, perhaps the Reclassify or Con Tool will be better. ... View more

Have you upgraded the geodatabase?  Or considered trying to create a new geodatabase and then copy the mosaic dataset to that geodatabase?  After copying you should be fine to create the overviews.  If you do not want overviews you can always increase the value in the MaxPS to allow them to be seen instead of the overviews. ...

I wonder after your extract if the statistics were present on the raster or if there was a stretch that could be applied.  Depending on your settings in your mxd, you might need to generate the statistics and apply the stretch. ... View more
