Free satellite image for image segmentation testing

Question

I need some free satellite images (panchromatic) to test some segmentation algorithms.

I have searched the web but I didn't find any resources our websites that provide free satellite images.

Thanks.

Answer 1

You can fill this form and request for a free samples from Geoeye of IKONOS imagery.

http://www.geoeye.com/corpsite/solutions/learn-more/sample-imagery.aspx

or alternatively GLCF has 4 IKONOS images samples that can be used. You can download them from here: http://glcf.umd.edu/data/ikonos/

Note: IKONOS 2 has 4 multi-spectral bands of 4m resolution and 1 panchromatic band of 1m resolution. You can just use the Panchromatic band if that is your requirement.

Answer 2

General search engines of satellite granules

You can search and download Landsat images from Earthexplorer or Glovis services. You'll find several collections there.

Landsat panchromatic

Landsat ETM+ provide a panchromatic image at band 8 with 15m resolution. One example here, from WRS-2 Path 29 row 30.

LDCM misson

Be aware that Landsat LDCM mission scenes will be available soon at the same website, by the end of May.
