Summary
Background
A 10- inch Chevron oil pipeline that was transporting crude oil near Salt Lake City bursted at the Emigration Canyon. 30,000 barrels of crude oil has already flowed down stream to about 7.5 kilometers distance. I have been contacted by city officials to put together maps and a contact list for residence that are in the affected area.
Method
Task - 1
I identified the location of rupture spatially and create a 250 meter buffer along the 7.5 meter stream reach as affected area. The parcels affected were identified and 4 maps showing a close shot of the affected area along the steam reach were identified. I also created an index page to provide an overview of area impacted by the pipeline rupture. I also made available an interactive map on for easy viewing.
Task - 2
I made a pdf document containing list of contacts of residents of the affected area.

Summary
The exercise showed that about a total area of 351 hectares were affected along 7.5 km stretch of stream. This lab gives an effective introduction to spatial analysis in GIS.
