Usually, we remote sensing types ignore country boundaries: they don't really make much sense, as they are not aligned with MODIS pixels ;-) However, I was asked what's the easiest way to produce a global mask of countries, so that all th grid cells (say at 0.5 degree ...

So I have just spent a week visiting at the VU Amsterdam. During this visit, I have also given a talk on EOLDAS. The slides are availabe from here.

In a previous post, I demonstrated how to stitch and put together a number of MODIS data files. This is useful and interesting, but in the end, we are interested in analysing the data we get out of the satellite. One first way around this might be to extract time ...

MODIS has been around for some 12 years. There are many products that have large time series over the whole globe which one can use to study things. So I might want to produce a a timeseries of the 8-day Gross Primary Productivity (GPP) product over say the UK. Moreover ...

So, it's quite tricky to play around with these geospatial datasets: they have a myriad formats, these keep changing, and you can never know what metadata will be available in them. A clever way around this situation is to use tools that allow you to read most of the ...
