[GRASS-user] time dependent variable

Hello. I have a netcdf file that I’m visualizing in GRASS. I first convert the parameters to GeoTiffs (using gdal_translate) and then incorporate into GRASS via r.in.gdal. Each file has 48 time steps (one per hour for 2 days). Is there any way to show the progression of my data in GRASS? I want to show which schools (or other such data) is affected by the path of my data (in this case, smoke from a fire). Any have any pointers?

Thanks,
Katie

If you're interested in making animations then on the GRASS wiki [1] there are several suggestions.

One of the options is exporting the maps as png files then running a tool called gifsicle to combine them into an animated gif. I've used this [2] to make nice animated maps.

I’m not so interested in making a movie; I want to be able to explore different layers of my maps as I see the data progresses. From the wiki page, there doesn’t appear to be a way to do this, though.

Thanks,
Katie
