Re: [udig-users] GeoDB file Data Formats and uDIG
|
Hi Shawn,
For uDig 1.1.x the options are not the best. There is a HSQL
datastore but it does not have indexing and hasn't got a lot of bug
fixes so that is not a good option. The postgis is the best but I
imagine that you want something a little more light-weight. GML is
not good because it is more of a interchange format and would be very
slow for editing or even zooming in/out.
I believe the plan is to use the H2 datastore on trunk.

Dear fellow uDIG users,
I've had no luck from the uDIG devel list so I thought I'd see if
users
could maybe provide some advice or pointers on an issue I am trying to
resolve.
I'm in the final stages of investigating the options for using an open
source GIS product for over 600 clients. The options are now uDIG,
QIS,
gvSIG. uDIG has some appeal being a Java custom client over a C++/C#
client.
Really we're only after a basic map interface with a lot of custom
dynamic forms to capture data, print maps and reports (PDFs). Not
rocket
science by any means.
I'm pretty happy with the way uDIG is progressing and the features
that
you get "out of the box".
In the back end however I am wondering what format will help us to
manage a file-based geodatabase type structure ?
I am after a structure similar to shapefiles with "related" DBF's, and
unfortunately we cannot have PostGIS running, just a set of files.
Will GML "do it for us" ?
The Shapefile format doesn't cut it for us because we have a need for
long-text (memo) fields and one to many relationships in the data.
Can anyone suggest a format that we should look at (or is anything on
the horizon like SQLite spatial, H2, HSQL ???) ? I notice that
GeoServer
uses a H2/Java db for the EPSG tables, but can you do a similar thing
for uDIG ?
I've also got a much larger spec for the system if anyone is
interested
in discussing what we require and what might be suitable.
Any ideas greatly appreciated.
