A common desire of the user of AutoCAD is to connect with Google Earth, to be able to work on the image that that toy has, although its accuracy is questionable, every day we find better material and it is useful instead of having nothing. Today we will see at least two alternatives to do it:
A. With the ImportGEImage command
This is the implementation of that Laboratory toy, that from the AutoCAD 2008 comes integrated. For this, only three steps are required:
1. Configure the units. They must be in meters, just enter the UNITS command, and make the adjustment.
2. Assign projection. This should be in lat / lon and with Datum WGS84. To do this it is done:
Map> Tools> Assign Global Coordinate system
Then we selected Lat Longs, LL84, with negative west.
2. Import the image. Write the command ImportGEImage and you're done. Unfortunately, it only exists for AutoCAD Civil 3D / Map and since it only asks for a central point it falls where it can, and it has to be scaled, moved, rotated. The other problem is that it only comes in gray scale as is the agreement between the two companies. To send an image to the background, touch the border, press the right mouse button and choose "Display order> send to back"
B. Using Plex.earth tools.
This tool is from Plexscape, which together with XANADU present an interesting solution to integrate Google Earth and 2007, 2008, 2009 and AutoCAD 2010 versions, both for Civil3D, Map, normal AutoCAD (this is great) and Architecture. It has certain similarities to the functionalities that Brings integrated Microstation.
1. Install Plex.Earth tools. Must Download it from the page of Plexscape, when installing, the AutoCAD version is chosen. When it is executed for the first time, a panel is raised to register the version, you must provide an email address and go to the account and for the link that they send immediately. It does not matter if it is installed for different versions of AutoCAD, it is only activated once and with the PLEXEARTH command the menu is lifted, in case it does not do it when opening AutoCAD.
It is to be understood that the dwg must have assigned projection and metric units of work.
2. What Plex.Earth does. The best thing is that you can work in UTM, without having to go to geographical coordinates. The region is chosen and then the area in the boxes on the left. Few smokes call my attention at first sight, after a comment that was In one of my postI have decided to try it and it has impressed me with its practicality. Now I tell you what it does:
- Synchronize the AutoCAD view with Google Earth. This is done with the second icon, when you select it, ask for the box and immediately move the Google Earth view until you synchronize it.
- Place marks in Google Earth. This is done with the third icon, activating it allows you to place points that will be created in Google Earth. It is possible to make MULTIPLE points and assign a descriptive with option NAME. In the example, I am using a map of a new urbanization, which in the image of Google Earth is still an African palm plantation.
- Get the center point of Google Earth. Always on the third button, and place a point in AutoCAD, with the center of the window that has Google Earth displayed.
- Import current view of Google Earth. This is with the first icon, in Import current view, and what it does is go to Google Earth, copy a printscreen, get the extent and bring it as an image. Interesting, better than the tool already brings AutoCAD because it comes in colors, with better resolution and how it uses three control points (not one such as AutoCAD) is coming as requested.
- Extract the mosaic image. From the best I've seen, it's done from the first icon, with the option "Create imagery mosaic", Same asks to define the area, then mentions how many boxes the mosaic will have and a panel is raised in which you can choose if the image is downloaded in color or grayscale, you can choose to download automatically and also individually, Being able to obviate those that do not interest with the option "skip".
The last button is to configure aspects such as:
- Work units.
- Extra margin of image: this is great for the compass and watermark of Google Earth to be out of the box.
- Timeout: how long to wait for the capture, you have to increase it to the one that comes predetermined according to the type of connection that we have.
- Image format: can be jpg, png, bmp, gif and tif
- Image path: where the downloaded images will be stored, there is an option to be in the same path as the dwg.
The trial version is fully functional, for 7 days or a limit of 40 images. Licensing forms range from $ 23.80, depending on the time and number of images, to licenses of 6 months or one year; Also in this post you can see the What's New in 2.
