Checking feature overlap using ArcPy cursors

Question

I have a set of geometries that I want to check whether they touch another geometry. I have created a tuple "tiffs" where I want position 0 when touches is true. tif[0] and tif1 are strings. The following code processes with no errors but no output in the print statements at the end. Confirming in the image below, there is overlap with many features and both features are in the same projection. Why am I getting no output?

list_tif = []
with arcpy.da.SearchCursor(boundary, ['SHAPE@']) as search:
    for r in search:
        for tif in tiffs:
            with arcpy.da.SearchCursor(tif[1], ['SHAPE@']) as cursor:
                for row in cursor:
                    if row[0].touches(r[0]) == True:
                        list_tif.append(tif[0])
for p in list_tif:
    print p

Answer 1

One potential issue:

Your two geometries must be in the same spatial reference, so check this.

More importantly:

You want to use geometry.overlaps instead of geometry.touches.

list_tif = []
sr = arcpy.Describe (boundary).spatialReference
with arcpy.da.SearchCursor(boundary, ['SHAPE@']) as search:
    for r in search:
        for tif in tiffs:
            with arcpy.da.SearchCursor(tif[1], ['SHAPE@'], "", sr) as cursor:
                for row in cursor:
                    if row[0].overlaps(r[0]) == True:
                        list_tif.append(tif[0])
for p in list_tif:
    print p

I'd look into intersect, spatial join, or select by location for options that should take less time.
