Georeferencing an image with AutoCAD

In another post we talked about georeferencing scanned maps or Google Earth images, we saw how to do it With Manifold y With Microstation, in these entries you can see more details of how to get the Google Earth image, the utm coordinates and how to cut them.

Now let's see how to georeference the image with AutoCAD

1. Entering the coordinates

To enter the UTM coordinates in AutoCAD, it is done with the point command. (Drawing / point / multiple point)

Then enter the coordinates of this form:

From the command bar would be:

Point, enter, coordinate, enter, coordinate, enter ... until the all entries.

The coordinate format is: "coordinate x", "coordinate y", so that they would be

431512,1597077
431838,1597077
431511,1596838
431837,1596838

If the system does not accept them, it may be because the configuration of points management is not according to the format, so write on the command line PDMODE = 2

If you do not see the dots or they look very small, select format / point styles / and choose a more visible format.

You can also Import from excel

Entering the points should look like this:

Now what we should do is insert the image, these are done with «insert / image manager»

We click on the button «attach«, Then look for the image and indicate that the point of insertion and scale will be activated on the screen.

Then select the left corner, with the snap on the point, and the lower right.

Ready, the image is georeferenced to the specified coordinates.

2 How accurate are Google Earth data for cadastre?

Do not use this for serious work, because that does not serve GoogleEarth data. Previously we had talked about «Precisions»That have Google Earth data.

  1. I found a utility to georeference in AutoCad images that had their corresponding "world" file:

    GeoRefImg new Repositions georeferenced raster images automatically according to their World files (VLX for AutoCAD 2004 / 2005 / 2006, 2007 / 2008 and ADT)

  2. Hello! Thank you very much! You do not know how I appreciate it.

    A greeting!

  3. Hi Ruth, to capture the image there are some tools and also you can do to pure printscreen check those post.
    capturar In mosaic
    with Arc2earth
    with AutoCAD

    Also in these post I speak as it can be georeferenced In aggis

    And above all I recommend that you see a post Favorite topics Where there are several ways to download, upload and georeference

  4. Hello ... .. and you know how to take that GoogleEarth image and georeferencing in ARcGis? You would be very helpful if you give me a clue.

    a greeting

  5. Hello, thank you, it is very helpful, thank you, thank you, you have uploaded this information to the internet and if you have more of this subject, please do it, thank you ...
