I have 30-40 raster layers and each raster has approximately 40 columns. The attribute/column names are very long, and the beginning of each column name is the same. During the extraction process, these column names are truncated, losing a lot of information regarding the variable/column name.

I am, for example, using Extract multi values to points to extract from .tiff to a shapefile point feature class.

For example:

vpr_Avg_1970to2010_m01Jan_800m is truncated to vpr_Avg_19 vpr_Avg_1970to2010_m02Feb_800m is truncated to vpr_Avg_20

.... vpr_Avg_21

Is there any way to keep the entire column name?

I'm working with ArcMap 10.1

    What are the exact steps in your "extraction process"? – PolyGeo Jan 31 '14 at 1:00

Shapefile format cannot support column names longer than 10 characters (a limitation of the dBase format). If you converted to an enterprise geodatabase (ArcSDE) table the limit would be 31 characters (30 in Oracle). File geodatabase supports 64 character column names.
