In reference toyour article on surveyors and GIS, you ask for success stories. I have none-only what you've written.
do agree that surveyors should start working toward a better GIS system. [In
New York’s GIS department], there was no surveying involvement, which led to a
positional problem of correct line work jammed together to make a pretty
picture. Some of the data were digitized or scanned from other towns and just
applied like an appliqué over stretched boundary lines.
product is being passed off as accurate. But it’s not all accurate, although
some parts are. Positionally, the lots on their map were not GPS'd and are not
surveyed, so I don't see the surveyor ever going by the wayside. It is one of
our jobs to maintain measuring accuracy, and by law we are licensed to certify
accuracy. The last time I checked, a GIS technician IS NOT A SURVEYOR!
GIS department that I deal with never sets foot out in the field, so how do
they know what they are even looking at? Have they ever set up a transit and
shot building corners, property corners, curbs or ditches? Do they even know
what a tape is or how to use it? Are they licensed?
deed says a lot is one acre, it should be one acre-not some trumped-up
shapefile made to represent two acres.
believe that surveyors should understand the complete picture of GIS-know how
it works or how it’s built, know what's good and what's bad. It might [be a
good idea] to get law passed stating that only a LICENSED SURVEYOR should run
any GIS department so that all control is not lost and the public does not get
The surveyor of today must try to make advancements in
their industry. There is plenty of room for such advancements and many avenues
for them to follow.
