I gladly flipped through my own fingers the first edition in Spanish of the magazine GIM International, which after many years has become a Important reference In the geomatic environment.
This is what Durk Haarsma says in his welcome editorial,
The Spanish-speaking world is very diverse and great in itself, with challenges and opportunities alike and an incredible pace of development, also in the field of geomatics. In recent years, I have met many readers from both Latin America and Spain, who have told me that there would be a great demand for a magazine in their own language. Well, here it is!
And this is how we will now have a magazine that will come out three times a year, with a wide range of articles from both our own region and from around the world.
This first edition brings an interesting interview with Rodrigo Barriga Vargas, the current President of the Pan American Institute of History, which is based in Mexico. Rodrigo takes a tour to the rhythm of eight questions in the thread of the trends of Latin America in the use of geoinformation. He talks about the antecedent and role of the PAIGH, some significant examples in the region, the development of the Cadastre and the challenge by the IDEs within the framework of SIRGAS, GeoSUR and UN-GGIM.
Among other issues, draw attention:
- GNSS Positioning. This is an educational article by Mathias Lemmens that can put in context any GPS enthusiast who has been lost in the thread of so much novelty, to understand the history that has taken the global positioning since the exit to the market of the first GPS devices in 1982, up to the vision of 2020 when we will have four fully operational GNSS systems with worldwide coverage.
- Use of El drones To measure volumes in open pit mines. This is in Chile's experience at the Chuquicamata spde mine, and explains how taking advantage of autonomous controlled flight units can process 266 images in less than an hour and a half on a flight to 250 meters high using the Pix4D software. It is interesting that this, done with a terrestrial scanner (TLS) would have required the need to access the trench, 2 days of terrain, extrapolation to generate the digital model and data availability up to 4 days. Apart from the obligatoriness of blind spots, use of more vehicles, operators and the final result hardly differed in an 1%.
- On the same subject of UAVs, Lomme Devriendt expands on another article in which he speaks of micro-drones of low speed, that fly to heights of 70 meters, with a coverage of almost 29 hectares per hour.
