I have a series of tables (TAB files) that represent the calculated values for a corresponding .tif image. These tab files have the same number of rows and columns as pixels in the tif images. The tif files are georeferenced and correspond to a study area I am using and I want to be able to extract the tab info for only the values within the study area. Anyone have any suggestions on how to go about this?

Or if I can just relate the table to the tif so each column and row is related to the corresponding pixel of each column/row in the tif.

I'm using ArcGIS 10.1 for Desktop.

I would (providing the TAB and tif files have exactly the same cells):

  1. extract the centre of each tif pixel as an xy coordinate
  2. write the xy file to csv (1. & 2. can be done together with gdal)
  3. read the xy file and TAB files into a program (R/python/whatever)
  4. stack the TAB file columns
  5. join/merge/rowbind the xy and TAB files and export to xyz
  6. read the xyz file into the GIS of your choice and make a raster

Finally, make sure you don't get data in that format again - it sounds like a total chore and a recipe for errors!
