Lab 2 - digitizing
Creating a map Google Earth

Your assignment is to pick about 1 square mile here in the Kittitas Valley and map change over about the past 20 years. Well, more like the past 15 years. The earliest Google imagery I see is the 2000 data. However, this place has changed a lot since then.

So

1) surf around and pick your square mile. Be sure to find somewhere in which there is significant change (shouldn't be hard). Most places that are irrigated have changed.

2) digitize 6 different layers, 3 for each date. One pair will be landuse polygons, one roads, and one buildings.

3) create one or two nice maps withing Google Earth which demonstrates the change.

First you need to create a project folder named Lab2 (never put spaces in either folders or filenames, stick to DOS naming conventions) to keep all of your features in.  Work off your flash drive - and be sure to save all your files to this subdirectory.

Next, fire up GE Pro and create a new folder in your My Places area to the left. Call it whatever you will. Make sure it's selected. Then, any points, lines, or polygons you create will show up inside that folder. You can also drag objects into the folder if you create them elsewhere.

The tools you should be using to create place marks are on the top panel in Google Earth, left to right.  Points can be marked with the thumb tack. These symbols can be changed according to the place marker.  Polygons can be created using the polygon tool.  Lines can be created using the path tool.  Each tool allows you to add a description.  Describe each of your features. 

Once you have finished creating each of your layers, you need to turn this into a .kmz file. Right-click on your project folder, and select Save Place As... or click on the folder and then go to the File menu, and select Save Place As... Save the kmz. to your jump driveEnter a name for your .kmz file, and click Save to save it your jump drive.

Once this is done, make the map(s). Once your map is complete, you need to create an image from the map.  Make sure in your viewer you can see everything you want to capture in the map.  Once you have that, go to FILE > Save - Save Image (save it as a jpg). In GE Pro, you will see some things pop up. Add the legend, title, description, etc. Play with the Map Options. Save the image.

Pop into Word and drop your map into a word document. Print it out in color (get it to Steve or use any other color printer). Be sure to check Steve's schedule.

Turn in your final map(s).
