Draft SO432, GIS Fall 2008

Remote Sensing Lab

You will download and open in MICRODEM two data files:

1.  A global satellite image at 8 km/pixel and from http://earthobservatory.nasa.gov/Newsroom/BlueMarble/.  You will register it and display it in MICRODEM before you leave today.  See the help topic on "NASA Monthly Global Images" in the MICRODEM help on how to do this registration.  The 2 km/pixel image is better, but may not display in computers with limited memory.

2.  The Geocover 2000 that covers  the area you want to do your project on, from https://zulu.ssc.nasa.gov/mrsid/.  See the topic "Mr Sid Imagery" in the MICRODEM help.

While these are downloading, do this lab/tutorial which  is included in the help file for MICRODEM, under Tutorials and Labs on the table of contents.  If you open that page of the help file, the links will work and the embedded graphics will be present.

You will answer and turn in the following questions, based on the Annapolis TM image:

• Which TM band has the lowest spatial?  Why is this?

• Which TM band has the most detail? Why would you say this?

• How is the 15 m TM band different spectrally from the 30 m bands?

• Do a classification of the Annapolis TM image into 4 categories, and discuss how this works.
