style='font-size:12.0pt;font-family:Papyrus;color:maroon'>I have just been to
an ESRI workshop where we discussed things like ArcPad and other GPS devices
linked to ArcGIS. Obviously it was very detailed but my query is much more
general. I would like to know what functionality UDig has in terms
of linking to handheld GPS’s. For instance we are currently
considering (how far we will get is another issue entirely) sending our
inspectors out with GPS’s and having them log what they see in terms of
things like address, business type, land use etc. and then linking these
coordinates to the specific land parcel. The data could be very specific
i.e. an address number or perhaps even a longish comment. I’m sorry
I cannot be more specific but we are basically brainstorming at this stage.<o:p></o:p></span></font></p>

style='font-size:12.0pt;font-family:Papyrus;color:maroon'>I have played around
with UDig as front-end for a while now and have found it rather slow – is
this the way it is or are there some tweaks that I could try. Obviously
I’m comparing it with ArcGIS which is rather unfair but I’d just
like to know. Are there any other desktops other than UDig and QGis that
I should try. I’m not quite ready to go delving into the other
database-related stuff quite now and am specifically looking at smaller desktop
applications with some minor editing of mainly existing shapefiles and using
existing aerial photos as “backdrops” (therefore my query re MrSid

to a certain extent I’m not comparing apples with apples but currently I
am experimenting trying to utilize features that can/will impress the
unconverted and match or even improve ArcGIS functionality. My initial
investigations seem to indicate that OSS might not be quite ready to take over
large organizational GIS functions (in Ekurhuleni Metro for instance) but I am
also very interested in the smaller users as we have many requests from outside
parties who need to read shapefiles but cannot afford an ArcGIS kind of
application.<o:p></o:p></span></font></p>
