Geographic Data Collection for Geographic Information System

      A technology integration of Geographic Information System (GIS)
software, Global Positioning System (GPS), wireless data
transmission, Personal Computer (PC) and laser range-finding is
disclosed.  Significant improvement to GIS data collection is the
result.

      The most difficult task in today's GIS environment is data
collection.  Statistics indicate that 80% of the effort involved in
using a GIS is collecting and inputting the data.  The data that is
to be collected is typically located in the field.  Using today's
data collection techniques there are usually many people involved in
the collection and input of data to a GIS.  This causes significant
overhead costs, a time lag in database update and potential input
errors in the data.  A technology integration between GIS software,
the Global Positioning System (GPS), wireless data transmission,
personal computer and laser range-finding would significantly reduce
the GIS data collection effort.

      In an example scenario, a field data collector can point to an
object whose location is needed in the GIS database.  The Laser
Rangefinder working together with the GPS receiver and a
microprocessor can calculate and correctly format the geographic
location and other various attributes of the object.  This spatial
and attribute data can be converted to one of many GIS data formats
(dependent upon the specific GIS software product).  Th...
