Convert Image Coordinates from Google Earth to Autocad. Before loyal readers of your search blog continue reading the article below, it’s a good idea to read the previous article on your search blog, namely Import Google Earth Images to Autocad Without Plugin Application so that you don’t get confused where did you get this picture from? how to do it? because here we will discuss the continuation of the previous article. In this article, the search for knowledge admin will describe in detail how Convert Drawing Coordinates from Google Earth to Autocad. how to convert the coordinates of a plot of land so that the image has been imported from google earth to autocad without using additional applications such as Plex Earth the area and length of the plot of land can be known. It’s impossible that we can only see the shape of the plot, but we don’t know the area and length of the plot of land. To find out, please continue reading the article below.
How to convert image coordinates from Google Earth is as follows:
-
Open the 3D Autocad Map that you are using and the drawings in the previous article are also open in AutoCAD, On “Task Panes” open “Map Explorer” on “current drawing” right click then select “coordinate system”.
-
Click “Select Coordinate System” indicated by the number 1, then fill in the search field “LL84” without the quotes indicated by number 2, the question is why LL84? because these are the initial coordinates used by Google Earth, then click the “find” indicated by number 3, it will appear as shown in the red box at the bottom, continue by clicking “OK” until all the coordinate setting displays are closed.
- Save the worksheet via “Menu > Sava As”. Determine where the file is stored, create a name for the file you want to save then click “save”.
- After the image is saved, close the working width that you opened earlier and create a new drawing by clicking on the part indicated by the arrow below.
- Well, here we will do a coordinate transformation. On “Drawing” we click “Attach” like the picture below.
- Look for the file that you saved earlier, here I saved the file on drive E, but drive E doesn’t appear, so we have to display the drive first. Click on the part designated by the arrow number 1, on the alias drive designated number 2, enter the name of the drive that you are showing, here the Student Blog will display drive E, then in the column “Drive Alias fill in E (without colon), and in Actual Path fill in E: (use colon)”, select “Add” and close. Now the desired drive can be opened.
- Find the name of the file that you saved earlier and it will appear as shown below. select Add” and click “OK”.
- If the above steps are successful, then below “Drawing” there will be a DWG file name.
-
The next step to perform a coordinate conversion is to open “Map > Tools > Assign Global Coordinate System”.
-
on column “Current Drawing” we will determine the coordinates of the destination, select “Select Coordinate System” on “Category” select “Indonesia”.
- After the image is saved, close the working width that you opened earlier and create a new drawing by clicking on the part indicated by the arrow below.
-
In this section the coordinates are adjusted to their respective regions, for the Student Blog admin area use UTM 47N coordinates, then select “OK”.
-
For the UTM zone in your area, please see the zone image below, click the image to enlarge.
-
Next “Select Drawing” click the name of the image earlier, then select “Add” and click “OK”.
-
Select the coordinates of the initial image system, fill in the initial coordinates of the image “LL84”, click “Find”, if you find it click “OK”.
- right click on section “Current Library” what’s in the tab Task Pane and select “Define”.
- select “location”then select “All”. and click “OK”.
-
The next step is to check the options “Draw” indicated by the number 1, then select “Ext Zoom” indicated by number 2, and select “OK”.
- Then select “Execute Query”.
-
Now the field will automatically appear as shown below. It is hoped that no part is missed, because if one is missed, the land area cannot be displayed.
For the coordinate transformation has been completed, the next step is to know the area and length of the imported land parcel. For the steps starting from importing images, converting coordinates and re-exporting images from autocad to google earth, please read the article below; If you don’t know how to calculate land area using AutoCAD, please read on How to Calculate Land Area With Autocad.
