GEO 426 – Final Project
Crisp – Slowing The Gypsy Moth Poster

2. Pt. I Data Sources

3. The Base Layer Data
Obtained States, Counties, Area Boundaries From Gypsy Moth Foundation website at :

4. The Thematic Data
Information about trap placements is stored in a database at MSU in the lab that I work at
Data is represented as x,y coordinate pairs and has numerical insect capture as the z
Most recent data from 2007

5. How data was extracted
select A.utm_east, A.utm_north,B.ZONE, A.state, A.county, A.usgs_code, A.grid, A.total_catch from gypsy.gm_historical A, gypsy.quad B where A.usgs_code = B.USGS_CODE and A.year=2007 and A.total_catch>-1 order by A.state

6. Created a surface from the dataset
Brought the resulting delimited text into a shapefile
Created a point coverage and converted to raster with IDW
Searched 4 adjacent points within 1 KM radius because this is how the traps are laid out
Result was my interpolated surface with catch total as the Z value

7. Pt. II Map Purpose

8. The Map Purpose
My lab needs a poster displayed in the Nat. Sci Building to represent what we do.
This is intended to be viewed by a general audience of students and faculty or staff
It is intended as a map that tells a story and to be read as opposed to glanced over.

9. Pt. III Map Design

10. Moth Presence
Borrowed idea of embedded hill shading to represent moth presence as ‘elevated’ trap capture
Breaks at 10/30/100/
Accomplished this with
an AML script to shade
a tiff with the Z value
of the Grid surface

11. Bringing it together with project activities
Integrating with the existing data

12. The generally infested area
Generally infested area represents no trapping, no actions. It a area where things are overrun
Represented in solid gray-green
A neutral color

14. The monitoring areas
This is where traps delineate the leading edge of the insects spread
Defines the action area
2 areas varied lightness of blue because order is implied primary - secondary

16. Action Area
This is where treatment occurs on isolated colonies ahead of the expansion front
Used lines and arrows to delineate and infer movement
No solid continuous color – why?

18. Finishing Touches Questions?
Added text ‘explainers’ to tell the story behind the project
The legend is a quick story as opposed to only labels
Counties are labeled because those are the smallest civil action units
Questions?
