Preprocessing of satellite image

• Room M240 computers• PCI Geomatica http://www.pcigeomatics.com/

– Linux operating system– You can run it as follows:

• Login to student computer, check that it is in Linux (SuSe)

• Open console

• Write nexus and give Your password

• Write geomatica

• Useful PCI-stuff– Tutorials http://www.pcigeomatics.com/services/support_center/tutorials/tutorials.php

– Frequently Asked Questions http://www.pcigeomatics.com/services/support_center/faqs/faqs_main.php

Preprocessing of satellite image• Username and password from Katri Koistinen• Calendar in door of M240 so you can reserve time

to use PCI• In case of computer problems, user licenses, etc.

contact Juho Kolari, jkolari@cc.hut.fi, M315.
