Please some advice,
Initial data:
- a route composed by the roads network.
- a line representing a GPS track.
NOTE: The GPS track is not exactly on route The mismatch can not be
mathematical modeled - it is random.
I am using ARCGIS 9.0 and ARCGIS 8.3.
I tried the tool LOCATE FEATURES ALONG ROUTES - with GPS track as line -
error.
I tried the same tool LOCATE FEATURES ALONG ROUTES - but with GPS track
as POINTS - 60% of points lost. Even if the Search Radius is set to 30 m
it looses points located at 1-1.5 m from the road.
Does anybody used the Snap GPS Points to Route script developed by Dany
Ghandour (http://arcscripts.esri.com/details.asp?dbid=13689)?
