This sounds like you need help with a HW problem. Check out the SPGWR package cran.r-project.org/web/packages/spgwr/vignettes/GWR.pdf

comment Null values coerced to zero (0) when exporting to csv or txt
I used the Extract Multi value to Point in batch mode with .tiff files. The NULL values are really NULL, but when exporting the attribute table (as csv or txt), they become zeros.

comment Want data from multiple rasters, but only for given points
I keep getting an error message (Error 999999). I'm extracting about 60 .tiff files (climate data) to feature class data in a file geodatabase. I need the feature data to be in a .gdb because the attribute names of the .tiff files are very long (aprx. 20 - 30 characters). When I run Extract Multi Values to Points, it creates new columns for the 1st four rasters and fails. However, the 1st 4 extractions are all null value. Any idea whats going on?
