Häberling et al (2008) explain that 3D maps can be presented on a large variety of display media. The Brisbane city 3D model, built by produced using artificial intelligence (AI) photogrammetry method from the different sources: OpenStreetMap (OSM) data, Open Source Digital elevation model (DEM) LiDAR data, Free satellite imagery, shows city development and planning processes (Snecket, 2019) There are many examples of 3D maps or models of reality made by different technologies with very high usage. We could conclude that 3D maps are the most suitable products for this purpose (Adami and Guerra 2006). Second more users can be identified from different cartographic product user groups. This means that when reality is described and visualized, social, economic and cultural data should also be included. They wrote about “more representative” and “world widespread” digital cartography. 2010) use this new direction for cartography to identify and evaluate different user requirements and needs.Īdami and Guerra (2006) outlined the integration of the acquisition, management and representation techniques for geo-referencing data processing. Many scientists (Petrovic 2001, Bonchev 2009, Stanek et al. Every cartographer takes attention to users, every map should supply users with necessary information for represented objects and phenomena. The three-dimensional (3D) technologies, and the application of modern techniques give us evidences for development of cartography as a science and practice of map making. If you don't have Civil3D, you can do it with the Plex.Cartography is one of the most ancient and at the same time, one of the most modern sciences. In the case of AutoCAD Civil 3D 20 it is already integrated. This tool only works with 2008 versions, both AutoCAD, AutoCAD Architectural, AutoCAD Civil 3D and AutoCAD Map 3D. Once the file is unzipped, it is executed and the installation path of the AutoCAD version where we want the add-on to be installed must be chosen, in case of having more than one program, an installation must be made for each one.Īlthough it is a process authorized by Google Earh, the image is in grayscale and not in color, by Google provisions. To install this application Should be downloaded from the AutoDesk labs page. In the rotation we assign 0 Now we assign that material to the mesh through the "materialmap" command with the "planar" option And that's it, we change the mode from "realistic 3D view" to shaded mode (shademode).In the offset options between mosaic images (U offset, V offset) we assign 0.In the tile options (U tile, V tile) we assign 1.In the units of scale we assign you to fit (fit to gizmo).Then from AutoCAD, in the material panel, we assign the image as material.In the image displayed in Google Earth, we save it with the option file / save / save image.Then select some views that facilitate the isometric visualization.Īlthough the image is imported in grayscale, for Google's sake, if you use the trick of converting the image into material you can get it in colors as seen in the following steps: If what you want is to see the image captured on the surface, select the “realistic” option from the “3D modeling” panel. The system will immediately ask you for the corners of the image and rotation. If you do not have any of the two previous programs, but only AutoCAD, or Architectural, the option to indicate the lower left corner will be activated and the file will be inserted with the measurement units in a mesh (3D mesh) of 32 by 32 squares. In case of having AutoCAD Map3D or AutoCAD Civil 3D, the mesh will hunt georeferenced between the coordinates of the box of Google Earth (as long as a projection system is defined for the drawing in use) and the image will hunt in this box. Then we activate the icon indicated on the right, through the text command “ImportGEMesh” When opening AutoCAD, you should not minimize the GoogleEarth window, nor close it, but keep the maximized view that you want to capture. The better approach we have, we can obtain a better resolution, as we had discussed in the previous post. It is required to open Google Earth, deactivate the terrain layer, the north compass and the orthogonal view. The trick is the same as We saw with Microstation, Creating a material and even solves the problem that the image is grayscale. We used to talk about how Import an image from Google Earth to AutoCAD now let's see how to import the surface and make this image is in color and can hunt on this surface 3D.
