3D Cities and GIS 2011 trends
The third edition of Geoinformatics magazine has arrived, with some pretty interesting topics. Eric Van Rees surprises us in a short entry editorial, after his impressions in the Globalgeo of 
Barcelona, where he says he was motivated to write a special article -That sure will see soon- on the positioning of open source software in the geospatial market. Then on pages 22-23 he explains in more detail, although for some time we have seen his interest in open technologies and approach to Hispanic initiatives, having impressions of his level are important to create greater awareness of what we know, but what we must sustain in the incursion that projects such as FOSS4G have had. It is not so important that those of us who are already involved in this hear it, but rather the decision makers at the level of private companies, governments and companies that market proprietary equipment and software of recognized brands.
3D Trends
There is a whole article about the tendencies that Bentley hopes to materialize with BentleyMap and the exploitation of I-models. Three full pages dedicated to what could be the vision that large geospatial software companies have in the niche that means integrating large cities into three-dimensional models where, rather than texturing parallelograms, it seeks to link the different variables of sustainability and land use planning to the infrastructure network .
I remember the theme from Baltimore, with the emphasis assigned to infrastructures, that link created by man to interact with nature. But the spirit is not in analyzing the objects individually -What is already done- but as a whole and trying to convert into algorithms the complex relationships that exist in its entire network and the variables of the fourth dimension: time and its relation to value.
It is an astral topic for our Hispanic countries, where the priorities are different, almost all because of the customs of our politicians -Because someone has to be blamed-. But seeing what Helsinki in Finland, Montreal in Canada and Rotterdam in the Netherlands will build will be useful to test and systematize what we will promote a few years later with much less money, with another context. The gain is in the trends, systematized models or at least based on OGC standards that will respect Open Source programs and those proprietary ones that are not arrogant when they refer to the BIM concept.
But we should not dismiss them as issues that do not apply to our contexts. Cities should consider territorial planning with higher priority, land use becomes important not only to display a beautiful painted map. The impact that the demographic explosion is producing on environmental pollution and gas emissions, its relationship with climate change, natural disasters and, increasingly limited sustainable natural resources, must be considered.
Geomarketing and Google for GIS
This is another interesting article based on an irreversible trend that carries what was initially known as the Clearinghouse, now more mature with the broad approach of IDEs. Voyager is a solution that seeks to solve the handling of spatial data by facilitating access through easy searches and interaction operations for different levels of CAD / GIS users.
I recommend that you take a look, because Google could surely be walking there. For now Google Maps and Google Earth are there, but they are only spatial data viewers; All web pages, blogs and documents continue to be searched in an abstract way from the Google form, with the entry of social networks another data bank was added: people. But the idea of looking for things relative to a specific geographic quadrant is still a great need and Travel Is one of those who aspire to offer something beyond this.
Will the satellites die on 2012?
Some time ago I recommended watching the movie KnowingSomewhat absurd science fiction, but based on scientific studies that predict that 2012 will be the year where the sunspot cycle will reach its maximum peak in the era when we have space covered by satellites. The 2012 film is added with another less creative approach and on the other hand the interpretations of the Mayan calculations that could not even predict its destruction now regain strength and add to the bad taste of the gringo cinema for keeping people in a stress for the fatalities.
Well, as is known, many satellites that are now space junk have been damaged by solar explosions. And the fatality has taken the hair of several, who mention that by 2012 the entire constellation of satellites that now allow us to use GPS could be damaged. Another Y2K that will stress us little, but think about air navigation, the application to land, maritime, arms transport ... anyway. If they take the issue further and say that the satellites that make the Internet work, if they turn our guts to all ... imagine a week without access to everything we have in email, uf! I don't even think about it.
It closely resembles the conspiracy attributed to the Program HAARP. But I recommend you take a look at the article where it talks about the advances of the Global Navigation Satellite System (GNSS).
Other themes
I recommend going to the site and reading the issue; preferably download it as a PDF for your collection, lest it be accessible via the Internet by May 17, 2012, XD. Later there are other smokes involving ESRI, Intergraph, Leica and Bentley.
