2 weeks of Latin American values ​​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 push the health of the collaborative ecosystem. For this, they mount a map on GIScloud 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:

• 135 volunteers Indicated their interest in participating.
• 345 data provided.
• Information from 15 countries.

Of course, the number of users interested in collaborating (135) is not representative of those who have actually done so to date. The following table shows the amount of contributions by 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 contribute yet.

Of these data, almost half have been taken from published offers.

Almost 50% of the reported values ​​correspond to urban properties with dimensions less than 500 square meters, if we consider the value “up to 500 m2”. There are some classes that duplicate the range, since they were changed once the data collection had started, especially "up to 1.000 m2" and "from 1.000 to 5.000" that would definitely have generated an unuseful result.

Finally, the result of data by country indicates the level of influence that the researchers promoting the project and the websites that have promoted the initiative have. Argentina stands out, with 30% of the data, Brazil and Honduras with the other 30%, it is clear that this is going to change because there are still 15 days left but we congratulate the efforts of those who have wanted not only to know what happens in the rest of Latin America but also to collaborate with the data to which they have access in their own country.

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:

Here you can see the progress of the map.

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