GIS Assignment 10
Detailed Project Proposal
At this point in the semester, you should have completed your data acquisition or be close to doing so. The
goal of this assignment is for you to lay out in detail exactly what you will do for the final project using these
data sets and how you will get there. This is a written assignment - you do not need to turn in any maps
unless you feel it would be helpful in your explanation of steps. The objective of this assignment is to have a
clear road-map for your project, and to get any final feedback from the instructors on how to proceed. You
may copy relevant sections from Assignment 9 if they have not changed.
For this assignment:
1.
2.
3.
4.
Briefly describe your project goals and the spatial questions it will address
Provide an annotated list of the GIS data layers you will use plus any tabular data sets - include data set
name, description, data source agency and URL if applicable, and key attributes variables you will use (e.g.,
population, illiteracy rates, crop production, conflict type)
The data creation and/or data processing/analysis steps that you expect perform - you can provide this as a
numbered set of steps or in a flow diagram. Be as specific as possible, relating the project step to the data
layer(s) - this will be the road map for your project.
The products you will produce (list of maps and tables)
1. The ultimate goal of this project is to create a vulnerability analysis for regions in Thailand most
affected by the 2011 floods. I will create a flood extent zone which shows the average flooding in
Thailand compared to the extreme 2011 floods. Using this map, I will show what areas are typically
affected by floods and what areas were uniquely affected in the 2011 floods. I will show the effects
on population, land use, roads and utilities.

3. 1) Extreme flood extent
2) Create average flood extent (find intersection between key flood extents)
a. Use clip and union functions or raster calculator to add up which areas have the most
overlap (can be turned back to vector afterwards)
3) Overlay analysis on population, land cover and infrastructure
b. Clip to extent of flood zones
c. Zonal statistics—calculate totals
d. Potentially combine all three to show full impact extent
e. (what kind of land use is being impacted?)—what is more important kind of land use being
impacted?
f. These figures will be compared to average and extreme floods
4. 1) Extreme flood extent map showing how bad the 2011 flooding was.
2) Average flood extent map to show areas typically affected by Thai flooding.
3) Overlay maps that show either extreme or average flooding against population, land use, roads
and utilities.
