OpenJump 1.3 (more GIS analysis, faster, better)

source: SlashGeo

There are more and more Open Source Projects coming along though which is the better of the bunch?
Not saying this is the 'best' though users are different to the developers.
OpenJump GIS is one of the better all round 'Free GIS' programs because:

1. It supports common GIS formats (.shp, .tif, .gml etc).
2. You can EDIT the data - lots are free but this one you can fully edit the data.
3. You can do some GIS Analysis!
   

Buffering for Free, OpenJump does do plenty of spatial analysis.

Spatial Analysis built-in (no plugins required!)

• Intersect, Buffer, Union, Symmetrical Differences, Centroid
  
• Generalisation
• Polygonise (converts lines to polygons)
• Join attributes by spatial location
• Thiessen Polygon Creation
• Attribution Queries

Additonal 'Plug-ins' can be loaded - though it's best the download them separately and unzip them on you computer the folder.


More Geometry Functions: Line Merge

Future Suggestions? - More of the same, this is great for students and non-commercial, non profit organisations with limited budgets.
Maybe a Print View/Layout function if need to print
Support for (.osm and .gpx for OpenStreetMap) would be very helpful to many 'map makers'

OpenJump can also export to common formats (.gml, .wkt, .shp and postgis tables)

We mentioned other open source GIS software such as Quantum GIS, GRASS GIS, uDig and gvSIG amongst others.

UMapper Routing

UMapper Routing

The video shows all the new and clever functions of the New Routing system implemented by UMapper





"After weeks of development and some rigorous testing, the new *Routing Tool* is available in the UMapper map editor. The new tool makes it easier than ever draw complex, multi-point routes. In a matter of seconds you can map your walk or drive without manually tracing each step. Once a route is created, it can be unlocked for further editing."

One the back-end, UMapper are using the powerful MapQuest routing service which is currently available in the United States, Canada, Australia, New Zealand and most of the Western Europe. More geographies are coming soon.
