SO432, GIS Fall 2009

GIS Registration and Vector Digitizing

Objectives: This lab will teach you

• Registration of data sets.

• Digitizing of vector features, both point and line.

For a sample of what we will be doing, go to http://www.usna.edu/Users/oceano/pguth/website/kml/normandy_geomorph/normandy_geomorph_mapping.htm where you can see a sample registered map and file with the front lines.  You can also go to http://www.usna.edu/Users/oceano/pguth/website/kml/normandy.htm where there is file with daily locations for the divisions.

Insure that you have downloaded the newest MICRODEM.(do an update).

There is an option of the "File, Tools, Download data".  You must run it and do the following downloads:

• FW-tools: you will need this download to open the JPEG2000 files.

• Normandy DEM.

You will probably have to download and install DNR-Garmin so that you can digitize in Google Earth..

You will need these icons, which you can download by right clicking and then picking the save as choice.

Go to http://memory.loc.gov/ammem/collections/maps/wwii/date.html and download the daily situation map for the date assigned in the table below.  The file you get will be a JPEG2000 file.

Directions for the lab are in the MICRODEM help file, under "Tutorials and labs", "GIS" , "Register image and digitize" on the table of contents.

Requirements:

• This lab is entirely individual effort. You will not get any assistance from your classmates. If you need help, contact the instructor.
• You are to place the following files in a subdirectory with the date (xxJuXX1944) you are assigned, and then zip it and place it in the course dropbox on Blackboard or email it to the instructor:
  • The PNG file for your date (converted from the JPEG2000 file).
  • The DBF file with the registration information for the map
  • The KMZ file with the map, front lines, and division locations, correctly symbolized.  This should be at least 1 MB in size; if not, it probably does not contain the map files.
  • The shapefile with the locations of the US divisions on that day.  The DBF file will have the NAME of the division, an ICON field with the correct symbology, and a DATE field so that your database can be merged with the others.
  • The shapefile with the locations of the front line on that day.
• You are to write a discussion covering:
  • How well do you think you were able to register the image. 
  • How well do you think you could digitize the front line and the division location.
  • What are the advantages and disadvantages of stream and point digitizing modes.
  • Include a GIS map, with proper cartographic conventions, with your front lines and the locations of the divisions, with the SRTM DEM as the background.
• This will be due Friday 10/16/2008 before COB.
