Make notes below as you follow the demonstration in Lathrop 305

Using the PCs in Lathrop 305 or 401 or the Field laptops:

1. Open ArcView; check to make sure that the following extensions are checked under File; Extensions:
MrSid Image Viewer, Image Analysis

2. Select View; Add Theme

3. Select Image and navigate to the folder OC/Hamilton/Images

4. Select the Hamilton.tif file

5. Check the Hamilton theme box in the view and examine the image.

6. Select View; Properties and select the map units and distance units as meters

7. Select View; Add Theme

8. Select Image and navigate to OC/Hamilton/Images

9. Select the two Hamilton MrSid image tiles

10. Check the themes to view on top of the Hamilton 7.5’ Quad image.

11. Examine the images and topo base closely. How closely do the images match? What is the
approximate amount of offset? Why does this offset exist?


12. Delete the MrSid images and zoom in on the area of the campus you mapped in Plotting outcrop
locations and contacts.

13. Select View; New Theme; select polygon theme and give it your name and location in folder
OC/Hamilton/Shapefiles

14. Make sure the new theme is selected. Use the polygon tool to draw in the locations of the outcrops you
mapped previously. Select View; Table and a field to the Table that contains the stratigraphic information
for each outcrop. It is easiest to do this as you map in the polygons. When you are finished, select Theme;
Stop Editing and save changes. You have now made a shapefile that shows outcrop and stratigraphic
information and it is registered in UTM co-ordinates. Use the legend editor to give different colors to the
Chenango and Butternut outcrops.

15. Select View; Layout and add a title and edit the legend if you wish. Show your results to an instructor.

16. Add the MrSid image file to the view and note the location of the outcrops.
