Photographs and other
images formed of pixels are called raster images, while images formed
of lines and arcs are called vector images. Bring in an aerial photograph
to display behind the objects in your map. Real-world elements in
the raster image line up with the geometry in your map and make it
easier for the viewer to get a visual orientation.
exercise uses the BuildMap1.dwg map
you created and modified in the previous exercises.
To add a raster image
- If you have not already done so, copy
the \Program Files\AutoCAD Map 3D 2010\Help\Map
3D Tutorials folder to My
NoteThe location of My
Documents varies, depending on your operating system.
For Microsoft Windows XP, it is usually C:\MyDocuments.
For Microsoft Vista, it might be C:\Documents
and Settings\Administrator\My Documents\Map 3D Tutorials.
- In the BuildMap1.dwg file,
the Data Connect window
should still be displayed. If it is not, open Display Manager.
Click Data Connect
- Under Data Connections By
Provider, select Add Raster Image Or
- Click the folder button next to Source
File Or Folder.
- Navigate to the folder in My Documents where you copied the
sample files. Find the folder containing the JPEG 2000 raster files
(originally called JP2K),
and select it. Click OK.
- Click Connect to
add the folder as a data source.
- Under Add Data To Map,
select the j-05, j-07, l-05, and l-07 items.
The folder contains multiple JPEG 2000 files,
each of which covers a small area of the city of Redding. Since
there are multiple items and you might not want all of them, they
are not selected automatically.
If your folder contains
multiple images, select the ones you want.
- Set the coordinate systems for the images.
- Select Combine Into One Layer,
so you can style the raster images as a single item in Display
- Enter a name for the layer, for example,
- Click Add To Map.
To see the results
- Close the Data Connect window.
- Right-click the new raster layer and
click Zoom To Extents.
