Maps are only a small tip of the iceberg when it comes to GIS and its potential.
We’re going to look at different GIS websites and eventually have you
make your own map using a GIS program that we have on the ILP lab computers.
Using the Property Map at http://gis.cityofsacramento.org/website/sacparcels/default.asp . Use Help in the upper right hand corner to find out how the tools work.

The Code Enforcement maps let you find and create maps on this site that show sites where abandoned vehicles, unsafe and dangerous buildings, graffiti, zoning violations and code violations have been reported. Below the map, you can use map sets to select User Defined maps or pre-defined maps already done for you.
Use these tools to identify:
-the areas that appear to have the greatest number of problems in each area (vandalism, grafitti, abandoned vehicles, etc.)
- areas that you feel are relatively free of problems

Distance to the closest methamphetamine lab and number of labs within ten miles of your home.
You've been introduced to a small part of GIS. GIS is used for tracking African elephants, toxic waste sites, effects of global warming, forest fires, and a myriad of other subjects. For now, you are going to use GIS to learn more about your neighborhood and a neighborhood where you'd like to live. Click on the link below for next week's task:
