LanDTM v6.1 Last update of March 26, 2010 Link to news, quickly March 26, 2010: New Update! Today we upload a new update of LanDTM program with many perfomances, refering to the correlation between the digital terrain models maked for the program and, the existing cartography. These are the new applications in the program in this update: Selection of Earth zones to import: It's created a new tool for you can select a zone of the world, which you want to import points, very much intuitive, showing a drawing of the world for you can select it easily. Draw digital terrain models and contouring on the UTM ellipsoid: Now, you can view, on the CAD, the calculated data over the real ellipsoid where they was gotten. Draw of meridians and parallels: You can draw the data of the meridians and parallels lines on the ellipsoid or on the UTM plain. Draw 3D faces on the datum surface: You can draw the 3D faces and/or Solids of the sea zones in all the areas of the selected terrain, so the visualization of the data will be more intuitive. Georeferentiation of any image: If you have a photograph, image, graphic of a Earth zone, and you want to put it as base in the digital terrain model that you are making on the CAD, now you have a tool, very dynamic, it allows to realize this operation. And, not only with a translation but too is allowed a rotation angle. What's more you can to do it in geographical coordinates or in XYZ, into the CAD. Export the contouring, points and triangulation to Google maps/Google Earth "KML/KMZ" files: Now, you can export any digital model, maked with LanDTM, to Google maps/Google Earth to share with others or, to can view your work over the real terrain, in 3D. For many years I've liked to create and upload on the internet a program that will help to the creation, visualitation and edition of Digital Terrain Models, D.T.M.s, and now I can offer this program.

So, is included the possiblity to have access to the digital terrain model of all the world, each 90 meters, since you'll be able to design any project in any area of the earth. It has prepared a data server, where are saved all the files which contain the digital terrain models of all the world, and only, you have to do a window of the zone you want view, and you'll be able to get the corresponding digital terrain model.

Not only the DTM creation with a reliable delaunay triangulation algorithm but this program is prepared for civil engineers and surveyors because it has the possibility to include break-lines and to draw the contour lines without smoothing or with a reliable smoothing algorithm and too, you can add labels on the contour lines. So, the program is the mother of all the tools for the people which need to work with DTMs. The program runs on Autocad 2007/2008/2009, Autocad 2010 and BricsCAD v10. I've gotten the "Protopo" libraries, (a famous spanish engineering civil and surveying program), and I've built this program. And the best feature is that you can edit and draw triangulation lines, as "LINE" entity in the CAD, and after, you can import to the program that triangulation quickly.

But, if you want, you have many tools to edit dynamically the drawn triangulation in autocad viewing the modifications as in the program as in autocad at the same time. This program is thought as a collaboration program, that's you can get it of many ways. If you are student or educational center you have the program fully free, but too, it's possible get it free collaborating with translations, good ideas for the next version and advertise it on the internet and friends. Too, you can make a donation from this page with PayPal.
