Load Satellite Images in Autocad

[phil1122]

Hi,

I recently acquired satellite images from Ikonos and Quickbird. The files include very large tif files (300 - 1400 mb).

I want to load the images in Autocad 2000/2004 and then draw proposed constructino projects layered on top of the images.

When I try to import the image, I get fatal errors. Are the files just too large, or is there a special way to do this?

thanks,
Phil Witherington

hi Phil, yes they sound too large. See if you can reduce their size someway. Photoshop might work but those sound like some huge images.
Good luck :)

You might also try changing the file format. If the originals are TIFF, converting them to JPEG will vastly reduce the file size with little loss of quality.

Some of these TIFF's are 1.4 GB?

Most of ours are less than 500MB, and we are mostly using ±18MB SID files.

Just curious about the 1.4GB TIFF files....

Download "Google Earth Beta" and do a screen shot of what you need.

It'll be loads smaller and just as usable if the area has good resolution to begin with

"Google Earth" aerials are not up to date nor can they compare to the resolution of commercial aerials.
