Due July 24th
Creating a location map and adding data.
You have collected a set of data on landslides in
the Portland metropolitan area and need to produce a location map
and do a visual analysis of the landslide intensity. You will find
basic basemap materials in the ESRI data set, and use this landslide
file to plot the distribution and volume of landslides resulting
from the 96/97 storm event. Here is a copy of the report that accompanied the data set. Here's
a step-by-step version!
1. Download the data
file.
2. Open landslides.xls in Excel.
3. Export the data as a Tab Delimited file (from the
Save As dialog box).
4. Open ArcView and create a new View.
5. From the Tables section of the Project Manager,
Add the file you just created in Excel.
6. From the View menu, choose Add Event Theme, and
choose which fields to use as X and Y coordinates.
7. Add the States and Counties themes from the Esri/Esridata/US
directory.
8. Create a new coverage of just Oregon counties.
(what projection are you in?)
9. Do your landslides plot in the right place? If
not, why? Are there other coordinates you could be using? (Reprojecting
Themes in Arview)
10. Use Graduated Symbols to show which landslides
had the largest volumes.
11. Sort your landslide table by volume to determine
the landslide that had the largest volume. Use the label tool to
label this slide (Theme Properties to change label field).
12. Create a Layout showing landslide volumes resulting
from the 1996/97 storm events. Show Oregon, and then a zoomed in
view of the study area.
13. Write a detailed report of how you accomplished
the above tasks. You should be able to re-create all of the steps
without relying on your memory. This is similar to lab notebook
in Physics or Chemistry. Turn in your report and include the map
that you made.
