Ticket #147 (assigned Enhancement: null)
Sample Rasters Listed in Fields tool should have a "skip missing rasters" option

Currently, the Sample Rasters Listed in Fields tool will fail if any of the rasters do not exist. It just passes the list of rasters to the ArcGIS Spatial Analyst Sample tool and allows that tool to fail with an obscure error message. It would be better if Sample Rasters Listed in Fields tested the existence of each raster and had a "skip missing rasters" option.
This is feature would be useful when sampling time series rasters. Each point has a date and you might want to compute the raster to sample with the ArcGIS Calculate Fields tool. But you may not have rasters for all of the dates. It is a pain to then mark all of the points for which the raster does not exist (although this can be done if you use the Find Rasters tool and join it to the points table with Keep All = FALSE).
