Week 8: Monitoring Fires
On This Page
Launch ArcGIS and Open the Aspen Fire Project
Investigate the Spread of Fire with Database Queries
- Create and execute a query that shows how far the fire spread on the first day
- Create a Query to Find Out How Many Acres Burned by the End of Day 2
- Create a Query to Find Out How Many Acres Burned by the End of Day 3
- Create a Query to Find Out How Many Acres Burned by the End of Day 4
- Select the area of fire on Day 1
- Select by Distance to Find Parcels within One Mile on Day 1
- Show the Results of the Spatial Query
- Repeat to Find the Parcels within a Mile of the Fire on Days 2, 3, and 4

Getting to Know Cartography in AEJEE
On this page, you'll review database and spatial querying as well as practice symbolizing and classifying data. You'll also find out how to gather statistics on numeric fields you query.
top of pageLaunch AEJEE and Open the Aspen Fire Project
- Launch AEJEE by double-clicking its icon on your desktop or by clicking its icon in the Dock (Mac) or Launch Bar (Win).
- Choose File > Open, navigate to ESRI/AEJEE/Data/AspenAE, select the Aspen_fire.axl file, and click Open.
- When the project opens, the base map displays a satellite image of Earth.
The image is part of the Blue Marble collection at NASA. It is a composite generated from several different types of data. Much of the data comes from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument, a remote sensing device on the Terra satellite. Latitude and longitude lines are visible on top of the image.

Investigate the Spread of the Fire with Database Queries
You might wonder . . . How far did the fire spread and how many acres did it consume by the end of Day 1? Day 2? Day 3? Day 4? Use database queries to find out.
- Scroll down to the bottom of the Table of Contents. Turn off the Blue Marble Earth image. Then turn on the Shaded Relief and False Color Aerial images plus the Daily Fire Perimeter layer. Zoom in until you can clearly see the perimeter lines.
- Scroll down to the bottom of the Table of Contents.
- Turn off the Blue Marble Earth image by clicking the box to the left of its name.
- Turn on the Countries and US 48 States layer by clicking the boxes to the left of their names.
- Turn on the Shaded Relief and False Color Aerial images plus the Daily Fire Perimeter layer. Look carefully and you will see a small dot in the Southeastern part of Arizona. This dot is all that is visible of the fire images and perimeter layer at this scale. It is necessary to zoom in for a closer look.
- Make the Daily Fire Perimeter layer active by clicking on its label in the Table of Contents. Then click the Zoom to Active Layer
button.. This is what the map looks like when zoomed in on the Daily Fire Perimeter layer.
