Make OSGeo4W Offline Installer

[Lurker]

maybe the most complete packages for opensource GIS software is OSGeo4W installer, its cover all GIS Software (Qgis, uDig, Grass, web-mapping, etc)

but this is an online installer, that we can choose from the repository the software that we ONLY need, but what for computer that do not have internet ?

of course we need to make offline package repository, that you can ship it to other PC and install it without internet, but at the building of this repository, we need pretty fast connection, here the step :

1. Get the OSGeo4W installer exe file.

2. Run it, and choose Advanced Install

3. Choose 'Download Without Installing'

4. Set the Local Package Directory to something like C:\osgeoPackages

5. Set your internet connection parameters to your local needs

6. Choose the packages you need. (Choose all packages to make complete packages)

7. Hit Next and wait for it all to be downloaded.

Now you have a package repository you can ship to another machine along with the installer exe file and do an unattended install. Assuming the repository is in the same place and the setup exe is in your path, from the windows CMD prompt do:

osgeo4w-setup.exe -q --local-install --root c:\OSGeo4w -l "c:\osgeoPackages\http:%3a%2f%2fdownload.osgeo.org%2fosgeo4\release"

which you can obviously put in a .bat file.

enjoy the offline installer
