Finally back after a long break. Happy new year to all.
Some people have voiced to me some concerns about my remarks about printing of maps in Ilwis 3.8. Or basically the lack of it. So I think it might be usefull if I explain a little bit better.
Babel
Though ILWIS was in theory multilingual from the 2.0 version, it was hardly used. I believe there was a (partly?) Italian version and a partly Spanish version, but they never ended up in the release version and/or were maintained. In the 3.7 this for the first time changed. Thanks to the work of Robin Prest and the money from the Geonetcast project a french translation of the user interface could be made.
The Losers
When implementing such a large operation as we are doing for the 3.8, there is inevitably functionality of the old code that has to be reevaluated. Mostly it is because you want something better, sometimes you have to remove some non performing functionality and sometimes you have to set priorities to determine what must be ported to the new structure and what will be dropped. This blog is about the losers of that judgment.
Stacking rasters
It is always difficult when you have sets of different overlapping rasters to visualize properly. Rasters are usualy a full coverage and so two rasters(or more) on top of each other block the view on one of them. As historically ILWIS is oriented towards rasters I felt I had to offer more flexibility when displaying rasters. So what options do we have? Well basically three
- Transparency. Make one layer (partially) transparent so you can view the “lower” layer
- 3D Orientation. seperate the two layers in 3D space and view them there
- Time shift. Quickly blink between layers to inspect different layers
