CAD approaches GIS | GeoInformatics March 2011

This month the new edition of Geoinformatics has arrived, with quite aggressive themes in CAD, GIS, remote sensing, data management; aspects that can no longer be seen in isolation. Geoinformatics 2 In principle I present an analysis of one of the topics that interested me the most, in the end a summary of other topics of this print.

AutoDesk has serious plans to enter the SIG.

A great article based on the interview with Geoff Zeiss, the specialist in geospatial subjects of AutoDesk that tells us about the plans of the company leads in this matter, with an integral vision of its users.

  • The history of AutoDesk is long, although it bets on the geospatial issue since the launch of AutoCAD Map in 1996, just when Oracle launched the SDO.
  • Then it was presented AutoCAD Civil 3D, in 2005, in the year that Google Earth appears.

Civil autocad 3d 2012The most outstanding thing for now is in the GIS division, which worked separately, this has been added to the large division called AEC (Architecture, Engineering and Construction). AutoDesk seeks to bet on BIM modeling in a comprehensive manner, which in a few words is summarized as a standard in which we stop seeing single vectors and see real-world intelligent objects, such as houses, walls, parcels, roads, bridges, with characteristics beyond of the 3D, among which is the cost and transactional history over time, such as the appraisal, replacement cost, productivity, updates, etc.

Not that AutoDesk is not already in the subject, what happens is that the positioning of the products revolve (outside the animation) around the Design, Civil Engineering and Architecture. This is seen with the recognition that Inventor, Revit and Civil 3D have; but those solutions continue to be for design purposes, very little is done for the long-term maintenance of infrastructures integrating data from different disciplines with products such as AutoDesk Utiliy Design and Topobase. We will have to wait for the product to materialize the Galileo Project, which is one of the most innovative smokes in the AutoDesk test laboratory.

We also assume, that from the versions of AutoCAD 2012 Which will be launched, we can see integration trends quite compatible with the I-model Of Bentley Systems, with different names but both betting on the same subject in which they benefit from the geospatial aspect the engineers, architects, surveyors and industrialists.

Although the field of utility is very broad, the BIM is still a somewhat astral concept, it is hard for us to stop seeing a parallelogram as a wall. Perhaps because the valuation of entities in civil engineering is something superfluous and empirical, even in the field of real estate a light bulb of a department is worth nothing for maintenance purposes; However, the issue is very interesting in the case of industrial plants where a valve can be US $ 10,000 and if it is not serviced, it can cause millions in losses.

So yes, we will see BIM applied to the CAD-GIS theme, and the subject that will entertain us will be smart cities (3D Cities), which is not so attractive for developing countries but with which it develops in countries such as the United States. United, Germany, United Kingdom, Kuwait and China, we will see an irreversible trend for the following years. We talk more than seeing buildings modeled in three dimensions with realistic textures and clouds passing over the sky (that even Google can do); it is about integrating into the design of an entire city environmental factors not fully applied in an integral manner such as the risk of natural disasters, climate change variables, natural resource management.

The theme is cutting-edge, and if AutoDesk goes there, the others will follow, if not in scope or vision, they will do so in compatibility. Cases such as the reconstruction of Japan's damage after the tsunami can be great examples, before the relocation of settlements with a territorial ordering approach in which intangible objects are mandatory variables of design and monitoring regulations.

Other topics of interest in the magazine

Other topics covered by this edition of Geoinformatics are also attractive. A pity that the version in Fluid runs quite slow, it is better to press the button to display it in pdf, wait a while for it to load, then do the right mouse button and download it locally.

The potential of images in the geospatial field. In this article it is visualized how, the traditional use that we have given to the images distances every day as the limits to where the remote sensing is arriving.

Civil autocad 3d 2012 WG-Edit, a new extension of gvSIG. One more step of gvSIG in its dissemination in the geospatial market, which again in a magazine with so much diffusion, gathers the potential of this free software in personalization. It is a whole smoked, which materializes in an extension for the management of road infrastructure data in an area of ​​Italy and that we could see in the 6tas. journeys.

Dreams in the capture of satellite data. This topic is covered with an article in which we are told that from 2014 we can have global elevation data in high precision, if everything goes well with the German satellite TanDEM-X launched in June of 2010. There is talk of 2 meters of relative vertical precision and up to 10 meters of absolute precision. The following image is a sample of the Tunupa Volcano and the Salar Uyuni area of ​​Bolivia.

How's ERDAS? There is a very complete article of the potentialities of this software, both ERDAS Imagine, the most known version in the world of GIS users, and LPS which is an application aimed at companies that make photogrammetric products, the extensions for ArcGIS and Apollo which is a luxury tool for visualizing data from different sources, locales, web map services and OGC standards. Even the article summarizes some of the trends of the company, among which draws attention to its development in multiprocesses to improve the performance of the equipment GPUs.

I recommend To keep an eye on the magazine, I have just summarized some of the ones that have caught my attention.
