Changing GIS data displays to observe different data patterns.
Students will identify location patterns of double-grated and single-grated
storm sewers, investigate patterns of storm sewer placements on East/West and
North/South streets and examine the number of storm sewers at the intersections
near the 48 Hours Video store, the Cup, and Broughal Middle School to determine
if enough storm sewers exist at those locations to prevent customers from getting
their shoes and socks wet as they walk into the stores or school.
1. Tell students we are going to display their collected storm sewer data in different ways to investigate if there will there be enough storm sewers near the 48 Video store, the Cup, and Broughal Middle School to prevent people from getting their shoes and socks wet as they walk into these buildings if it rains all day.
2. In a group setting:
Model how to launch AEJEE and load the following shape files:
Northampton and Lehigh County Roads, Rivers, Landmarks shape file, and student
collected storm sewer data points.
3. Use a projected computer image to show students how to change the map displays to show the data in different ways.
4. Review how to add street label names.
5. Show students how to display names to the landmarks file.
6. Show students how to change the color and symbol of the landmarks attribute color.
7. Explicitly model the thought process for identifying patterns.
8. Review the “Double Sewer” data pattern from yesterday.
9. Show students different GIS map displays by changing the colors of the storm sewer data fields to unique symbols with different colors.
10. Review how to change properties of each field attribute.
11. Show new map displays by creating unique symbols for (1) storm sewer types and (2) storm sewers located at intersections.
12. Review how to change attribute color.
13. Show how to change properties to identify sewer patterns at intersections.
14. Ask students if there appear to be more sewers at intersections or not at intersections.
15. Next, have students look at storm sewer patterns located on East/West streets. Ask students if there are any East/West streets with more sewers within a block than in other block areas? Use scaffolding to note that more sewers within blocks appear on East/West streets around Lehigh University’s campus area.
16. Provide a brief overview of the AEJEE tools.
17. Highlight how to select the SEWERS layer and Zoom to Full Extent.
18. Instruct students to launch AEJEE and load the following shape
files:
Northampton and Lehigh County Roads, Rivers, Landmarks shape file, and student
collected storm sewer data points.
19. Distribute the handout Changing GIS Map Displays
to each student and instruct students to complete the handout.
Students will identify location patterns of double-grated and single-grated
storm sewers, investigate patterns of storm sewer placements on East/West and
North/South streets and examine the number of storm sewers at the intersections
near the 48 Hours Video store, the Cup, and Broughal Middle School to determine
if enough storm sewers exist at those locations to prevent customers from getting
their shoes and socks wet as they walk into the stores or school.
20. Spend 5-7 minutes at the end of class bringing students back to the front of the room to look at the GIS display on a projected computer image. Have students describe how they changed properties to look at data patterns. Have students share the patterns they observed in the data and review and discuss student responses to the key questions.
