So far, Time Manager has been limited to vector layers. Support for raster layers has been on the wish list for quite a while. I’ve been considering different approaches and for now I have settled with one that keeps the way how raster layers work as close to the workings of vector layers as possible:
All layers have to be loaded before they can be added to Time Manager. The layers are added one-by-one and start and end time values are defined. (This differs from vector layers where start/end attribute are defined instead.) All raster layers that are not within the current time frame are set to 100 % transparency.
I’m not certain yet whether this is a good approach though. I’ll probably keep trying different approaches for a while.
This is a screen cast of the current status:
The plugin source is available on Github, as usual. It’s still going to take a while until there will be a plugin package including this feature.
I’m looking forward to reading your comments here or on Youtube. Do you think this approach is usable?
