Hi Everyone,
My name is Simon and I am an environmental consultant. I use a variety
of open source GIS systems and tools almost every day to analyse flora,
fauna and vegetation data. I am interested in OSGeo both from the
standpoint (or my underlying belief) that software and data should be
Simon,
You might want to look at PostGIS. It is a GIS extension to the
posgresql database. There are windows installers for it. There is a
shapefile loaded and dumper, so you can easily load a shapefiles into
tables then do SQL queries with geospatial function. The postgis support
list has a
Simon, you could do this as a PostGIS query. To take the polygon case, if
you loaded the data into a table in PostGIS called parcel (say), you could
run a query something like the following (not guaranteeing this is exactly
correct but something along these lines):
select a.id, b.id,
Peter others,
With PostGIS what is the best option for installation to trial this
option. Where would you enter the SQL query?
If you go to the PostGIS page it pushes you to UDig. Does UDig have the
functionality to send SQL statements to the database? Does PostGIS
install if I install UDig
Peter,
Tried loading PostGIS 8.4 crashed because no Postresaql.
Tried loading Postressql then PostGIS - this worked but no "simple
utility to load a shape file into PostGIS" could be found.
I found a SQL dialog box in the pgAdmin (GUI) but I found nothing but
HTML links in the PostGIS
Peter,
Sort of answered my own question. Found the EXE in the binary directory
of PostgreSQL.
Tried to get the program to work but I could not get the file to import
the shapefile into a database. I will need to spend more time working
on coming to grips with PostgreGIS, PostGIS and others
Dear All,
Is there any reccomendation for good books on following
topics (with many good examples)
1) Service Oriented Architecture
2) Web Services: XML, WSDL, SOAP, and UDDI
3) Web Service Security
4) Ext JS
5) Cloud computing platforms
Thanks in advance.

Peter,
Trying the QGIS+Grass option now. Lets see how that goes - experiences
to date put into the same 'steep learning curve' category but I try it
again using Giovanni's instructions. I will post my experiences about
trying to get this to work.
Cheers Simon

Giovanni,
I installed the QGIS + GRASS + PLUGIN as you suggested using the
OSGeo4W installer.
I can only use Grass Tools IF the layers are grass layers imported into
a new map set. I do this but v.distance does not allow me to select the
"From" vector file so the routine baulks.
I am either
