Embargoes on the web

Paolo Tarolli sent to me the following link where the Nature Geosciences (and Nature indeed) ask for an embargo on information about unpublished papers. They argue among other things:

" it may well be in our authors' interest to limit pre-publicity of their results "

Frankly, I disagree on the statement (Well they can require what they want for their journal).

I am contrary to any embargo. I noticed that in Physics the free distribution of Preprints was massive even before the present era of web 2.0 with no problems whatsoever. At the same time, I believe (actually Nature would probably agree with me on this point) that I am able to judge my Science's topics with the same deepness of any other of my peers, and  that getting any scientific information early  is very useful and propel the advancement of science. 
Granted this, it would be very difficult in the present times, to filter out any written information, from the public. 

Moreover, if scientists do not make the effort to show and make to understand the public how science work, how can we believe it will support us ?  If we do not give to the society a sample of what the scientific debate is, and what is about ... in the matter, how can we think our work will not be degraded to opinons ? If we do not grow people to understand the problematics of our activities, and the methods to solve them, how can we believe science can be adopted  as a better way of thinking, and not just because it provides products ? 

On the contrary I appreciate the EGU open access journals where the policy to show discussion papers, both improve the "preprints", and make more careful most of the peer reviews.

Wittgenstein teaches: what can be said at all can be said clearly, and what we cannot talk about we must pass over in silence.

Flood Observatory at University of Colorado, Boulder



The information comes directly from their site, and data were obtained mostly by using remote sensing data from MODIS. In fact, The Flood Observatory uses orbital remote sensing to detect, measure, and map surface water changes. It includes:





1- River Watch, an experimental satellite-based river discharge measurement system (example).

2 - The Surface Water Record, a comprehensive map record of the Earth's changing surface water.

3 - Active Archive of Large Floods, 1985 to present (listing and characterization of large flood events).




4 - Rapid Response Inundation Maps, for individual flood events.

A library of Georeferenced photos from the field

They can be found at http://www.eomf.ou.edu/photos/. Pictures are usually pretty boring at the moment. But the idea is interesting and possibly the database will improve. An idea to follow.


Clicking on the photo you should be able to get the data connected to it.  The information come from EOS the AGU weekly journal, and the relative article is here.

Free GIS Data

This is indeed a very strange blog. All feed up the same day, February 18, 2011 with 54 post about various data set. Two at least did not escape my attention.

The global Evapotranspiration map made by Antonio Trabucco  for the CGIAR-CSI :

Also the reference to the global DEM derived from the satellite Aster measurements is of interest for hydrologists, and according to some paper are better than SRTM data.

These are not the only good data you can find there!

Two other source of information about GIS data are remarkable:  those from Robert T Wilson and those one can find in Tomislav Hengl wiki Spatial-Analyst at the page of global data sets.  Another source of interesting data is here where you can find addresse a map of runoff data by NCAR/UCAR and some interesting considerations.


Naming Rivers

This is a variation on the themes inspected by Boetti and his wife in their "The thousand rivers". In this case, what is inspected is the name with which the river are addressed. Terms like "fork", "canal". Beside, the technology is outstanding. Below, please find the Great Britain.

The case of United States is:



The original sites, images, and explanation regarding how the maps where realized,  can be found at: http://spatialanalysis.co.uk/2011/08/naming-rivers-and-places/
The blog itself is very interesting to follow.

Open Source Software and Intellectual Properties

People often think that using an Open Source License for Software left freedom for any behavior. In fact, this is not the case.  Here you can find a presentation by Bruno Lowagie where he discussed the related issues and obligations.



Open source requires ethics, is a demanding exercise, and it is not about robbery.
