Raster to Polygon only takes integer (or string) - period. This is by design since 9.0 The reason is that too many individual polygons will be created in most cases. In the case where one really wants float output, then can multiply the raster by, say 1000, and cast to integer, convert and then divide by 1000. This workflow has been repeated many, many times in this Forum. Steve ... View more

Can you run Spatial Analyst's IDW with the data, output cell size and output location and raster format? Thanks Steve ... View more

Please try to narrow down the problem, viz., - use a smaller dataset, with and without a barrier - output to ESRI grid rather than fGDB - create a new fGDB and output to it - with you posted scenario, increase the cellsize and exclude the barrier and output to ESRI grid Please let us know which of these are successful.

Please have a look at the links that Eric provided earlier in this thread for a reference as to where it is documented. If you cannot add the 5x5 file then please contact Esri Support. -Steve ... View more

The "ASCII" raster format is a supported raster format. Which means that if the file has a .asc extension it can be used directly. Which means that you can use the CopyRaster tool to change and set the output bit depth. Steve ... View more

Look at "Create Subsets" in 9.3 http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?id=4003&pid=3999&topicname=Extending_ArcMap_with_the_Geostatistical_Analyst_extension or add a field to your dataset and use the "Calculate Field" GP tool using the following Python expression arcgis.rand("Integer 0 100") (you'll have to modidy the 0 100) or in ArcGIS 10, use the Subset Features GP tool -Steve ...

Reclassify to integer values and then divide by a value to create the probability raster. I.e, if you want all the values in the habitat raster that are forest, for example, to have an inclusion probability of 0.75, then reclass them to 75 and the use the Divide (by 100) tool to create the probability raster Steve ...

It is a layer created using the Geostatistical Analyst extension. If you created the output running Spatial Analyst or 3D then you'll need to specify a larger processing extent in the Environment and re-run the tool. Hope this helps. Steve ... View more
