MrSID images via GDAL on a Mapserver WMS server by hooking into it from uDIG. It
actually runs faster than what ArcMap can read the files from disk or via AGX
(ArcGIS Explorer) reading
directly from the file.</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=375093414-21112007><FONT face=Arial

<DIV dir=ltr align=left><SPAN class=375093414-21112007><FONT face=Arial
color=#0000ff size=2>2. This question can be a multi-headed monster. There are
several options:</FONT></SPAN></DIV>
<UL dir=ltr>
<LI>
<DIV align=left><SPAN class=375093414-21112007><FONT face=Arial color=#0000ff
size=2>You can install onto each machine and then connect to the central
datasource or web service you need (PostGIS, WMS,
etc).</FONT></SPAN></DIV></LI>
<LI>
<DIV align=left><SPAN class=375093414-21112007><FONT face=Arial color=#0000ff
size=2>Does the network involve virtual applicances or thin-clients? What is
the requirements of uDIG in the scope of what the client want's to do? If
virtualization is involved, installing it on each machine is not really an
option, and it would probally be best to run uDIG on a dedicated GIS Server
and have thin-clients / virtual connections use sessions on the
machine.</FONT></SPAN></DIV></LI></UL>
<DIV dir=ltr align=left><SPAN class=375093414-21112007><FONT face=Arial

<DIV dir=ltr align=left><SPAN class=375093414-21112007><FONT face=Arial
color=#0000ff size=2>3. From what I gather reading the
rest of the mail more indepth, the best options for adding tracklog data
(connecting mobile devices with a GPS) would be through the GPSBabel library and
importing the tracklog into the database. Alternatively you could also interface
the mobile devices from uDIG via GPSBabel and utilise the data, tracklog and any
attribute information you may entered related to the spatial entities (land
parcels, POI....).</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=375093414-21112007><FONT face=Arial
color=#0000ff size=2>As for the rest of Deon's mail, another Desktop GIS product
that could be used is Accuglobe 2007 (<A
href="http://www.accuglobe.net/">http://www.accuglobe.net/</A>). I am not sure
of the extent of it's openness in relation to OSS, but I do know it is a free
product that just requires registration to download and use. I have been
following the product closely for the last 6 months, and suffice to say it is
very powerful, has multi-platform installers (Windows, Linux, Mac (I think)),
and is faster than both uDIG and qGIS at this stage. It also can read various
raster formats and vector data from PostGIS and shapefiles, and from
Personal Geodatabases (I haven't tried that one though).</FONT></SPAN></DIV>

<P class=MsoNormal><FONT face=Papyrus color=maroon size=3><SPAN lang=EN-US
style="FONT-SIZE: 12pt; COLOR: maroon; FONT-FAMILY: Papyrus">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: 12pt; COLOR: maroon; FONT-FAMILY: Papyrus">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 as our Tiffs are huge!

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>
