1. A computer-implemented process for generating a two-dimensional stitched and annotated digital image of a site having a telecommunications tower thereon, said process comprising the steps of:
a. acquiring a plurality of digital images, still frames and/or video images of said site, said telecommunications tower, or both said site and said telecommunications tower;
b. generating a three-dimensional point cloud of said site, said telecommunications tower, or both said site and said telecommunications tower from said digital images, still frames and/or video images;
c. identifying predetermined excluded objects in said three-dimensional point cloud to be masked in said two-dimensional stitched and annotated digital image;
d. photogrammetrically generating said two-dimensional stitched and annotated digital image of said site, said telecommunications tower, or both said site and said telecommunications tower from said three-dimensional point cloud;
e. generating one or more superimposed intersecting grid lines, annotations, or both on said two-dimensional stitched and annotated digital image of said site, said telecommunications tower, or both said site and said telecommunications tower, said intersecting grid lines comprising a polygonal measurement area, a grid area, or both; and
f. masking any identified excluded object from step c. from said vector or grid lines of said polygonal measurement area or said grid area on said two-dimensional stitched and annotated digital image.
