More on visualizing collecting localities

Clearly short of something to say after the almighty media circus generated by the climate change hotspots publication, our friend Andy Jarvis is reduced to celebrating an embarassingly artificial milestone on the DAPA blog today. Normally I would treat such awkward space filling with the contempt it deserves, but today I’m in the mood to, well, fill space. So here goes.

Andy’s post is about the 90m-resolution digital elevation dataset he and his colleagues have been working on for ages. The milestone he trumpets is 750,000 visitors, but more important is the fact that the data is now visible in Google Earth, which I didn’t know. Here’s what a bit of Spain looks like with the normal Google Earth imagery, the records on show being from Genesys. ((BTW, thanks to Google for the Google Earth license.))

And this is what the same area looks like using the SRTM data:

Advantages to both, I suppose, from a purely aesthetic point of view.

Incidentally, some further playing around with Google Earth revealed a couple of collecting localities for Beta maritima (from GBIF this time) that are easily visible in Street View. Here’s an example, featuring a record from France’s Inventaire national du Patrimoine naturel (INPN), catalogue number INPN_21204166 in case you’re interested. ((Their website is worth exploring. If you do, you’ll find out, among other things, that Beta maritima, is found near the sea significantly more frequently than the average French plant. Unfortunately, the nifty plots and maps are not easily downloadable.))

More pain

Don’t get frustrated, there is always hope! We have now included the possibility of directly downloading the map of the recommended locations for genetic reserves in kmz, shp and tiff formats in the main webpage. This website is focused on the dissemination of information to the general public. For those interested in more detail, the webpage of each proposed site provided links to protectedplanet.net or Natura 2000 viewer where additional information concerning the protected area can be gathered including the download of the corresponding kmz file. Anyhow, the downloadable files at the main page should facilitate the job from now on.

Many thanks to Jose Iriondo for this comment on my recent post on the pleasure and pain of combining biodiversity data. It’s not quite as easy as he makes out. Yes, you can download the boundaries of protected areas from the sites he mentions. This is what I got for the Estrecho site in southern Spain.

The white rectangle is all I could manage to extract from ProtectedPlanet, having gone through the pain of registering, though admittedly I’ve had better luck in the past. It could be something I’m doing wrong. The green shape I got from Natura 2000 and obviously it’s considerably better. But it still does not have the Avena, Beta, Brassica and Prunus species data in the original website AEGRO website. For that, however, it sounds like we wont have to wait for long. Jose again:

Futhermore, we will soon include the possibility of directly downloading the kmz file corresponding to each of the Google Earth plugins of each proposed site.

Hope does spring eternal.

The pleasures and frustrations of combining biodiversity data

This website provides information on recommended locations, mainly in protected areas, suited for the establishment of genetic reserves for Avena, Beta, Brassica and Prunus targeted crop wild relative taxa across Europe, in the context of the AEGRO project. Available information includes ecogeographical data as well as an inventory of crop wild relatives belonging to the four target genera occurring at each location.

This is the map of the recommended sites:

Which is great, and even greater is the fact that you can look at individual species, and the suggested protected areas, using a nifty Google Maps plugin. This, for example, is the Estrecho site in southern Spain, which is where you find an endemic wild oat (among other things).

The problem is ((You knew there was a problem, didn’t you?)) that I can find no way of mashing these data up with anything else. For example, say you want to add Genesys data to see if any other species occur in this, or any other, protected area. I don’t see how. You know where those Genesys accessions are:

But there’s no way to combine the two. Or maybe you want to see if the area was affected by fires last summer. Can’t be done. You know where the fires occurred:

But there’s no way to combine the two. Whereas of course you can easily combine that NASA fire data with the Genesys data, simply by bringing both into Google Earth. ((And, yet again, thanks to Google for the Pro license. So cool.))

So I guess my plea is: if you’re going to use Google Maps or Google Earth to display your biodiversity data, please also make it downloadable. Maybe there was a reason why this couldn’t be done in this project. I’m all ears.

Oh, and there’s another thing while I’m indulging my hobbyhorses. Can’t we use some innovative approaches to add to these kinds of datasets? I mean, if it can be done for amphibians…
