Yesterday, I posted about Merging Tiled Images using Autodesk Raster Design.
Cropping Aerial Photography
Now that I have one image, I often only need a portion of it. This is especially true with road design projects- I just need an image that covers the road and some right of way area on either side.
You can make regular shapes, but I will use the Crop>Polygonal Region option to make a custom shape.
The image is cropped.
If you don’t like the black pieces, you could use a rectangular region, but keep in mind that black takes less time to load than detailed aerial imagery.
Circle can be useful as well if you need to focus on a specific radius.
Again, I’ll want to save this image with a new name and produce a world file. The major benefit to doing your image manipulation in Raster Design over an image editing program is that Raster Design understands that you need to keep things in the right location.
Working with these photos reminds me of a post I wrote about Conceptual Road Design Ideas and using imagery to complement planning exhibits.
James will talk about creating exhibits for planning and conceptual design in our upcoming CE News webcast on June 28, 2012 called: Planning and Environmental Assessment with BIM for Infrastructure.
