Working with Imagery

This tutorial describes the Plex.Earth 3 functions to import georeferenced aerial imagery into your drawing. The image source can be either Google Earth, or the new built-in Map Explorer. The availalbe options are:

 

  Google Earth   Map Explorer  
img_area_16.png Image on Area       N/A Imports a single  image into the rectangular area you specify in AutoCAD.
img1_icon_16.png Image from Current View             map_image_16.jpg Import Current Image        Imports into AutoCAD the image currently diplayed in Google Earth/Map Explorer.

Each Google Earth function is presented in detail below. Any corresponding Map Explorer function works in essentially the same way. The only difference is the imagery source and the importing speed (the Map Explorer is significantly faster).

 

Image on Area

Use this option to specify a rectangular area in AutoCAD which Plex.Earth will fill with a single Google Earth image.

 

Step 1: Select the Area Image command from the dropdown menu

Step 2: Select the rectangular region into which you want to import the imagery

Step 3: Plex.earth will import the image into your AutoCAD drawing

Tip: Use Draw Order -> Send to Back on your new image to bring your project back on top if the imported image covers part of it

 

 

 

Image from Current View

Use this option when you have used Google Earth to zone in the specific area of interest and want to import the exact contents of your window into your AutoCAD drawing.

 

Step 1: Select the Image from Current View command for the dropdown menu

Step 2: Plex.earth will import the image into your AutoCAD drawing

The image currently displayed in Google Earth will be imported into your autocad drawing. 

Note: Remember to use Draw Order -> Send to Back on the new image to bring your project back on top.

 

 

Create Mosaic

 

Use this option to specify a rectangular area in AutoCAD which Plex.Earth will fill with a series of  images, taken at the zoom level currently used in Google Earth.

 

Step 1: Select the Mosaic command

If the Eye altitude currently set in Google Earth is too high/low, you will be given a warning to zoom in/out before proceeding.

 

Step 2: Specify a rectangual area in your AutoCAD drawing

Step 3: The "Mosaic creator" window will appear, showing the grid of images to be imported.

If you do not want make modifications to the grid, choose to start capturing the images to proceed

 

Step 4: The selected region will be filled with a mosaic of Google Earth imagery

Tips16.png Tip: If the navigation tools on the right and the Google Earth logos on the bottom appear on every imported image, you can deactivate the former and apply a vertical image overlap on the latter in order for them to appear only at the very bottom of your mosaic.

 -  To deactivate the Google Earth navigation tools go to View -> Show Navigation and select "Never".

 - To set a vertical image overlap select "Image & Mosaic Options" from the Plex.Earth 3 Options and define the desired magnitude:

Polygonal Mosaic

 

Use this option when want to fill a polygonal area in your AutoCAD design with a series of Google Earth aerial images at the currently used zoom level.

 

Step 1: Select the Polygonal Mosaic command for the dropdown menu

 Polygonal_Mosaic_1.jpg

 

Step 2: Specify a polygonal area in your AutoCAD drawing 

Polygonal_Mosaic_2.jpg

The Mosaic Creator will appear. Select to start capturing images if you do not want to make modifications to the suggested grid.

 

Step 3: The selected region will be filled with a mosaic of Google Earth imagery

Path Mosaic

 

Use this option to a band along a certain path in Autocad, which will be filled with Google Earth imagery taken at the currently used zoom level.

 

Step 1: Select the Path Mosaic command

 Path_Mosaic_1.jpg

 

Step 2: Create a path in your Autocad drawing by selecting a series of points 

Path_Mosaic_2.jpg

 important.png You can also select an existing polyline of your drawing as the path by pressing the "Down" arrow, selecting "Objects" and then clicking on the polyline.

After defining the path, select the left and right swath which determine the width of the created mosaic on each side of the polyline. The Mosaic Creator will then appear. Select to start capturing images if you do not want to make modifications to the suggested grid.

 

Step 3: 

The specified band will be filled with a mosaic of Google Earth imagery
