Connecting a map with Google Earth

There are different programs to display and manipulate maps, among them ArcGIS (Arcmap, Arcview), Manifold, CADcorp, AutoCAD, Microstation, at GIS level, before we saw some Take advantages...

In this case we will see how to connect manifold To image services, this is also a way to download an image to store it georeferenced.

In another post I speak As is done with ArcGis

1. Download bookstores

First of all, if we have not done so we must download the image server applications, from the Discharge zone Because they usually do not come with the license.

  • 64bitImageServers.exe (111 KB) - for versions in 64 bits.
  • ImageServersPack.zip (16 KB) - for versions of 32 bits. Both contain the necessary .dll files to connect to Microsoft Virtual Earth, Yahoo streets / maps and Google Earth / maps. Once downloaded, they must be placed in the "program files / manifold system /" folder. These tools, according to Manifold's friends, are not theirs but of Georeference.org, the community where they were developed; Over time it has been mentioned that the tools work, but that Google has juggled to deny access; I recommend for this to keep abreast of that community.2. Connect to IMS servers

    First we open the map or component, and we move to the area that interests us to synchronize (you can assign coordinates, but it is more practical in this way)

    Once we are in the deployment that interests us, we select "file / link / image" and choose "manifold image servers"

    image

    • The window allows us to choose between Google maps / satellite options, Google maps / street, Virtual Earth / satellite, Virtual Earth maps / street and Yahoo maps / street. In our case we will choose Google maps / satellite image.
    • If you have a paid license from Google Earth (Pro or Enterprise) You can choose a url for a better resolution, otherwise, we leave the one that appears by default.
    • In the "scale" field, we choose the pixel size we want, which can range from 1 meter to 160 km. It is clear that the closer the deployment is, the better the resolution of the image will be.
    • In order for the system to capture the extent we have, we click the refresh button.
    • In case we want Manifold to cache the deployment we must check that option and the proxy button is to macar in case our intranet has it.
    • Then click on the "ok" button

    In the component area you can see the result.

    2. Assigning projection to the image service

    In the case of Google Earth, the download comes with a standard UTM (mercator) cylindrical projection with WGS84 datum. It is necessary to assign this projection, with right button «assign»

    It is a bit of a hassle to "assign or change" projection, so the best thing to do is not to use change.

    3. Displaying the IMS on the map

    For this, we only drag it inside a "map", like any other component, which is a similarity of the arcmap layer, to see it behind the maps it is necessary to drag it on the lower tabs, behind the one we want, and assign transparency to the map in front.

    4. Save the georeferenced image

    For this only right click on the component, and export, can be stored in different formats, recommended .ecw so compact. To bring the image, it is done «import / image» and after it has been imported, it is always necessary to assign it a projection. Do not forget to assign the initial Google projection (standard, cylindrical mercator wgs84), now you can change projection to taste, for example UTM zone 16 north, wgs84

  • To do this: right mouse button on the object marked above in red and we assign it «Universal traverso mercator / zone 16N / Datum wgs84» which in this case is the zone of Honduras.

    ... eye, this is another way of georeferencing downloaded images ... without battling the perverse as it showed in another post with Microstation or with AutoCAD.

    1. I have been reading in the Manifold forum, and apparently Google has changed the way of accessing the data so it seems that no one is being able to connect. The people of Manifold have not assured when they will make a new version of the connector that by the way is a tool not from Manifold but from Georeference.org

    2. I have Manifold 8 is a great tool, but I can not connect to Google Earth, I follow all the steps but it denies me access. How can I fix the problem?
      Thank you very much

    3. Hi. Very good your blog. I recently found it thanks to a reader.
      My question is if there is any dll to link with the satellite images of Yahoo.
      We have Google Earth, VE, Yahoo Maps, but in certain cases, Yahoo satellite has high resolution images where GE has low. That's why my question and need to link with Yahoo satellite.

      Thanks and go! Lots of MANIFOLD online information is missing. It would be nice to go doing small tutorials of simple and concrete topics for the user apprentice (like me). Thank you!
