Lab 5: Vector Analyses

In Lab 5 we have been given a task as a member of an Emergency Response Team.  A pipeline has burst and we are asked to use some basic analysis to draw the needed information.  First we have been asked to import a point into ArcMap.  This point represents the location of the pipe that has burst and is beginning to leak into Emigration Creek near the bustling metropolis of Salt Lake City, Utah.  


Files needed for this lab:

-Zipped lab 5 data
-Retrieve  "StreamsNHDHighRes_shp.zip" and "Parcels_SaltLake_shp.zip or Parcels_SaltLake_gdb.zip"  from Utah AGRC

Steps to import a point file into ArcMap.

  • Open a blank ArcMap and set the projected coordinate system to Projected Coordinate systems > UTM > Nad 1983 > Zone >12
  • Open a blank excel file
    • Create 3 columns   X, Y,  Details
    • Under the X value input  433321.8 
    • Under the Y value inpout 4512099
    • Under the Details put a name of the point.
    • Save the file then exit.
  • Return to ArcMap and import the Excel file you just created.
  • Right click on the imported excel file and click "display x y data"
  • Verify coordinate system then select ok.
  • Now we can see the point is displayed.  It is currently an event layer. So we must save it as a shape file now.
  • Right click on the file then select Export. 
  • Export the layer as a shapefile (shp)  Then to clean up the map we can now remove the event layer previously created.
  • Your point is now ready for analysis.

The EMS and HAZMAT Team have requested a map that places a 250 meter buffer around the Emigration Creek.  Any land parcels located in that buffer zone need to be contacted and informed on the situation at hand.  There was a special request to not include any lands owned federally.  We begin the selection process by doing a select by location.  We use the buffer layer as our layer to use as the mechanism that will select any parcels that intersect or are located in the buffer zone.  While those are selected we then use the select by attribute table.  By performing all of the selection at once rather then exporting the data after each selection we can save time.  While in the select by attribute table we must make sure we click the remove from selection tool at the top of the window.  This will remove values with the specified values from the selection.  In our case we want to remove anything that is federally owned.  

The selected parcels that were selected are within the contamination zone of our fuel spill and thus a list needs to be generated. 

Here is the finished indicator map.
Here is the indicator map that indicates spatially what is being displayed on the next four pages. 


You can download the entire Map Book for further viewing here:

This indicator map refers to four included sub-maps that show a more detailed breakdown of the contamination sites in each designated region on the map above.  If your house could possibly be in any of the regions indicated above please review attached pdf to see an all-inclusive list of parcels that are within the range of possible contamination.


The above map is of page 1 of the maps provided with the indicator map.  The red line as we can see is the buffer, as well as the pipe fracture point and then the affected parcels downstream from the accident. 

The above map is an example of what you will find in the 5 page map book available for download at the bottom of the page.  If you are within these boundaries you should exercise caution and contact EMS unless you have already been contacted and instructed what to do.




Here is an example of the parcels listed by zone then sorted by last name.  If you would like to view if your properties are affected, select the document below and verify whether or not your name is located on the list.  If your name is not on any of the lists you are not in the zone of contamination.  If you are on the list please vacate the property and wait for EMS to Contact you for further instruction. 
Here are the links to each list of Parcels affected.

If you would like the excel spreadsheets instead please click the document below. 
Here is an interactive map displaying the affected parcels for further property identification.  You may zoom in and out to find your property to see if it is among the list of those affected.
