Hi, Partially you have answer to you question. Iterate over your raster list with step 255 (as written in my last post) in loop, after creating DBF file with 255 columns and one row, use function arcpy.TransposeFields_management (http://resources.arcgis.com/en/help/main/10.1/index.html#//0017000000v4000000) to get DBF with two columns (name of the raster and value) and 255 rows. When you finished loop you can append all two-coloumn-dbfs to single file. Best Regards. Arek Hi Arek Thanks for that. That does solve the problem partially but what happens when you want to do more than 255 rasters? I have 100s of raster and I need to extract from them in one go Regards

Hi Arek Thanks for the reply. I am so sorry. I actually meant that the output (dbf) file has 1 row and 256 columns. How do I get my python to produce just two columns (label of the rater and value) for all the rasters that I choose. Regards

Hi Guys I have 1000's of raster files and I need to extract data from all of them. I created a shapefile with a single point and I run the code. The code extracts the data into the shp file but processes them in a row which then cuts off at 256. # Name: ExtractMultiValuesToPoints_Ex_02.py
# Description: Extracts the cells of multiple rasters as attributes in
# an output point feature class. This example takes a multiband IMG
# and two GRID files as input.
