Do you have those customers that are simply not capable of doing their own job?
We had a client order some very specific aerial maps and it was a duplicate of what we had done a few years earlier for them. Back then they had a real intelligent man ordering and using the maps. He retired and was replaced with a new college graduate with lots of degrees and book learning. She must have cheated on the exams to pass.
She changed the dates on the previous bid and set it to us. We did just what we did in the past. She called back and asked what the files with .prj; jp2 & j2w were and if they were like a PDF. Now to explain, a JPEG2000 file is a compressed image file kinda like a jpeg on steroids. We can take a tif file that is 10GB and compress it to 336MB with virtually no loss of image quality. Only mapping programs can open a 10GB tif or JPEG2000 files and it has the main image and two 1KB files that tell the software where the image is and scale.
She can't get PDF reader to open the files and wants us to make PDF files. That is NOT what was ordered. Oh well. I guess I will make her some files to use crayons and paste and maybe a post-it to piece together her pictures. Welcome to 1980!
