To know what uDig is and does, you can look at this post.
To use uDig, the first thing is to install it, following the instructions at the GIS website. After this first installation, install the Spatial Toolbox. Now you can think how to use it !
uDig pages are actually full of information, but I took a little of time to summarise them here too, and also to add some resources that are not available in the official website.
If you do not know what a GIS is, look first at:
- Introduction to GIS (well, for a more structured introduction, a very good introduction is de Smith et al., Geospatial Analysis a comprehensive guide, 2013 - which is available on-line)
- A presentation (just a little out-of-date) to jgrasstools and uDig
- Walktrough 1 - Installation of uDig 1.4.0
- Walktrough 2 - Editing in uDig and WFS
- To know how to work with map look at YouTube/udiggis
- Using the Spatial Toolbox
- Still in Italian: Working with GRASS (but is going to be translated: is it true Aroon ?)
- Using the Map Calculator by exploiting Jiffle (here its manual).
- The material about the tools to work with the Horton Machine is now in a separate post (and is still partially in Italian).
- The material to support the culverts, and sewer systems design as well as the documentation of the nettools for the design of water supply system is instead here, but in Italian.
For learning about the scripting capabilities of uDig, one can give a look at:
- to the post by Andrea Antonello on JgrassTechTips (which is a further source of useful information)
The new version of uDig support also geoscripting, and how, it is explained here.
In any case do not forget the screen-casts at:
