2 weeks of Latin American stock map collaboration

It has been fifteen days of evident evidence of how the mute SIG of Latin America is connected, under the context of collaboration that now allow information and communication technologies.

This is a project sponsored by the Lincoln Institute, with several days of smoking and coffee of the friends Diego Erba, Mario Piumetto and Sergio Sosa, who pose not only to take a research work of the behavior of the Value of soil in Latin America, But also strike the health of the collaborative ecosystem. To this end, they put together on GIScloud a map in which volunteers can contribute the knowledge they have of their context.

The results are more than interesting, when you already have at least 15 days of collaboration:

Of course the number of users interested in collaborating (135) is not representative of those who have actually done so to date. The table below shows the number of contributions per country, the last column reflects those that were intended to participate. There are some countries, such as Bolivia, Nicaragua and Venezuela that do not appear because they do not yet contribute.

Almost 50% of the reported values ​​correspond to urban properties of dimensions smaller than 500 square meters, if we consider the value «up to 500 m2». There are some classes that double the range, since the data collection has already been changed, especially “up to 1.000 m2” and “from 1.000 to 5.000” that would definitely have generated an unhelpful result.

Finally, the country-by-country data show the level of influence of the project's researchers and the websites that have promoted the initiative. Argentina excels, with 30% of the data, Brazil and Honduras with the other 30%, it is clear that this will change because there are still 15 days but we congratulate the effort of those who have wanted not only to know what happens in the rest of Latin America But also to collaborate with the data they have access to in their own country.

Giscloud

Those who have registered and have not contributed, see that it is relatively simple: just look at a real estate page of your city and look for those properties that have a geographical location in GoogleEarth, or a photograph that is easy to identify ; Something that can only do with practicality who knows his country.

As a preliminary result, we must recognize the potential of GISCloud, which allows not only analysis of tabular data as summarized in this table, but also spatial analysis with some interesting features.

The map can be uploaded as a WMS layer from the address:

http://editor.giscloud.com/wms/f8e2fd27e26e7951437b8e0f9334b688

Here you can see the progress of the map.

We congratulate the effort, which surely will already be thinking about a strategy to be able to continue feeding once the GISCloud trial licenses expire. Perhaps a practical form may be Google's service and its electronic sheets, or something similar, since the information collected at this stage is not representative for conclusive purposes.
