[GIS] Extract coordinates for series of georeferenced files in ArcGIS 10

arcmapgeoreferencinggeotiff-tiff

I have a series of 1900 spatially continuous images that are georeferenced. Each image is a tif file paired with a tfw file.

These images are easily open and shown in ArcMap 10. However, I need a way to extract and tabulate all of their associated coordinates (in this case, the centerpoints of each image) into a spreadsheet.

How do I do this? Please note that I have no scripting abilities.

Thanks!

In arcmap 10.
I think I would use the footprint feature (in mosaic dataset) and
then generate the centroid of those polygons.
add an x and a y field to my attribute table,
calculate the geometry,
then export to dbf and convert to xls.
Also found in this answer are several resources for esri help.

What you could do is:

In the original image, fill each area with a unique color, e.g. with Gimp
Georeference
Run Raster to Vector
Clean up the polygon geometries manually

It isn't nice code, but for your specific circumstance, here is some python that should save typing them out by hand:

f = open('list.txt', 'r')
lines = f.readlines()
for line in lines:
    lineparts = line.split(' ')
    outfile = open(lineparts[0], 'w')
    for i in range(1, 4):
        outfile.write(lineparts[i] + '\n')
    outfile.write(lineparts[4] + lineparts[5] + '\n')
    for i in range(6, 8):
        outfile.write(lineparts[i] + '\n')

(real code would sanity check, but I assume you can check the results)
