title: raster to point conversion using python
body: <p>I want to use a python script to convert several raster files to point files, based on the Value field in the raster.  However, I want to exclude the cells with "0" value.  Is there a way to do this in one step or do I need to copy the original rasters to new rasters and set the no_data value to 0?  Any recommendations?  Thanks.</p>
