Spatial datasets continue to proliferate, and evolve

A few more huge spatial datasets for you this morning, as I deal with jet-lag in a Maryland hotel room at 4 am.

Today there’s a high resolution dataset of the population of Africa. And an analysis of wetland protected areas.1 And finally a global dataset of particulate matter pollution. This is presented from a human health perspective, but it could have applications in agriculture too.

Bean production environments in East Africa.

I still want to know who’s keeping track of this stuff. Maybe you don’t need to, you can just google as the need arises, but somehow I doubt it. Would love to hear from the CGIAR’s spatial data consortium folks, if they’re listening.

Meanwhile, one of the participants in that consortium has announced that they’re updating one of their iconic products, the now oldish “Atlas of the Common Bean (Phaseolus vulgaris) in Africa.”

Bean accessions recorded in Genesys.

How long before they mash it up with that population dataset? And with the data on the location of genebank accessions, for example from Genesys.

Not that it hasn’t been done before, in a very crude way, as you can see in the map in Figure 2 below.

  1. Whether we could find spatial data from Google or whether we need some kind of special setup has not yet been fully resolved. At one time the CG centers starting using standardized metadata, for example:

    http://gisweb.ciat.cgiar.org:8080/geonetwork/srv/en/main.home

    Some still use this, including a recent gap analysis project that you would see on the link above. I prefer this standardized metadata – but not so much to help other people find and use data, but rather to document my own data for my own use. I understand that Google is working on some protocols for finding spatial data. But my sense is that this question has been put on the back burner because people don’t think it is all that relevant. They can seem to find what they need.
