When I saw this post at the WeoGeo blog on Voyager, I was psyched. The free version of Voyager searches your hard drives for up to 5000 geodata files, catalogs/indexes them, thumbnails them, and makes them easily searchable and retrievable; paid versions increase that data limit, and offer more features (concurrent users, network storage searches, etc.). You can even add links to online data sources like WeoGeo that support the Web Catalog Service (CSW) (live web demo here).
I’ve got data files scattered all over the place, so this would be a perfect organization tool for me. But I was bummed to find out that you need to have ESRI’s ArcGIS Desktop 9.3 or higher installed on your system, which I don’t. Nuts. But if you do have a supported version of ArcGIS, you’d be crazy not to at least try out the free version.
