[Gvsig_english] SUGGESTED FUNCTIONALITY gvSIG 1.9 (BN 1253) -- (repeat) need for default directory, project directory and temp directory

Mon Apr 12 12:53:53 CEST 2010

Ben,

Central databases are OK for the reference sets like statewide
vegetation, geology, etc but is too much effort for project related
files. Each project might have 20-30 layers that once the project is
completed never get used again (usually because the landuse is changed).

It is like archaeology. A developer requires a pre-development survey.
If artefacts are found then various layers would be created to conform
to state and Commonwealth legislation. As the referral agencies don't
have the ability to accept geospatial data most feedback is as a map in
a report. Once the report is finished the development occurs and the
geospatial data becomes redundant (except as a historic reference).

As I said, is is not really worth keeping all your files in a single
system as these smaller project files would just bog down the system.

In regards to the preferences in gvSIG - yeah, you can set a generic
directory for projects and shapefiles, but these variables are 'system
wide'. When you have 5-10 projects running separately you need project
specific variables. That is, these variables should be stored in the
project file not the program directory config file. Also, you don't have
a TEMP directory where temporary files can be stored. Depending on the
routine this can be in any number of locations.

Cheers Simon
