GIS Trouble and How We Get More Work
Posted: Thu Sep 23, 2021 8:41 pm
I just finished a boundary survey for the sale of a $9,000,000 home in Saratoga. When I arrived to meet the owner who was selling it, he showed me some documents. One was a perfectly good Boundary and Topo. It showed the property lines with many found monuments, trees, the house, etc. and was signed by a local surveyor. Then he had a Site Plan showing a design for an addition, pool and cabana - which were subsequently built and existed when I came to do the survey. The Site Plan showed the corner of the new cabana about 20 feet from the property line. Then he told me why he wanted the survey. He had been looking on a GIS or "google" or something - i am not sure exactly what it was - but it showed the property line running through the new cabana. So he was real concerned about that.
It turned out the cabana was only 15 feet from the property line. There were no monuments along the lines near the cabana so the contractor probably guessed a bit. I have received quite a few requests for surveys based on bad data from a GIS. So maybe they are not so bad after all!
