Exercise 1

Introduction to ArcView 3.3

This assignment introduces ArcView 3.3, a software product from ESRI. The goals are to become familiar with the user interface, learn how to add spatial data, how to change feature colors, how to add map elements like a north arrow and a title, and how to print a map.

Please note that while you have not yet been introduced to the skills good cartographers should use, do your best to make a nice looking map. Pay careful attention to what you’re expected to produce for each part of this assignment!

This assignment is due next Thursday, February 2. It is worth 4 points !

Scenario : You work for the Virginia Department of Transportation and have been assigned to the ice/snow removal team that covers Montgomery County. An ice storm is forecast to affect the county that evening, but the Weather Service believes that ice will affect elevations only above 750 meters. To target the roads most likely to be affected by the storm, use ArcView to find the roads that are above 750 meters. You will create two maps: 1) one that displays elevations and all roads in Montgomery County, and 2) a map that displays elevations and all roads but also identifies those roads that are above 750 meters.

Data Sources : To complete this assignment, you must use two different data sources for Montgomery County: streets and elevation data. Both data sets are available from the Data folder on the GISWEB2 server. Simply copy the "exercise_1" folder to your folder.

Procedure: This section provides you a general guideline of how to proceed. You are responsible for determining the steps required to complete the assignment!

ArcView Procedures

 Step 1. Start ArcView

Step 2. Add Elevation grid to the map

Step 3. Add the streets to the map

Step 4. Create a map of elevations and roads.

You now have all the data needed to construct the first map. Pay attention to the following information when constructing it: choose an appropriate color scheme for elevations, the title should say what the map is about, and there should be a north arrow and scale bar. Also state where the data came from (US Geological Survey for DEM data and US Bureau of the Census for roads). And be sure to put your name on it! Produce the map using the color laser printer.

Step 6. Create a map of roads, elevations, and elevations above 750 meters.

Finally, create a second map similar to the first except display all elevations above 750 meters in red. Be sure that roads are clearly visible above these elevations. Good luck!

Step 7. Submit maps to your instructor.

On Thursday (the due date), put both maps in your folder and hand them to your instructor.
