Regarding my inquiry into gps-enabled cameras, I got a few replies including
one from Steve Van Aartsen, the GIS Supervisor in Sioux Falls, SD. His
response was:
=
We are using a Ricoh Pro G3 for a project similar to the one you are going
to do. We are in the process of taking photos of every building in the City
and visually identifying the posted address. We purchased the model with a
GPS receiver attachment and the software that works as an extension (ArcGIS
plug-in) to ArcMap.
=
The project has been going very well. We had two interns work on it last
summer and they collected more than 30,000 photographs with corresponding
gps point locations in less than 3 months. We have approximately 15,000
left to do this summer and we just hired a couple interns to finish the
project this summer.
=
They are taking most of the photos from the window of the car so the GPS
coordinate is out in the street, but back in the office they are moving the
points into polygons of the building footprints. We could simply leave the
point locations where they were taken if we simply wanted to have the
photographs attached to a point, but one of the primary goals of our project
is to create a very accurate address point feature class. We currently use
the parcels and street centerline for geocoding points, but both of those
have some limitations. This process should create a very accurate address
feature class with the addresses being field verified by the field personnel
and in most cases can be checked by looking at the house number on the front
of the house in the photos.
=
The process of hot-linking the photos to the points is very easy using the
software that we purchased with the camera.
=
The Ricoh Pro G3 sounded like a good solution to me even before I got
Steve=92s response. I asked Steve about the cost and he said the package c=
ost
around $1300 with all the extras. Does anyone have any other responses
before start shopping for a Ricoh?

Scott,
did you see this article regarding GPS cameras and linking photos to Google
Earth?

Horizontal accuracy of 15m or better would be appropriate for the gps =

size and dependability are other important factors. Our max budget is $1500

I've looked at both the 'Ricoh Pro G3' camera and the 'Jobo photo GPS

devices for cameras=85
Thanks.
