ACTIVE LEARNING EXERCISE
Importing digital elevation data into Google SketchUp provide real-world, accurate terrain data for incorporating into your 3D SketchUp models. This week we'll utilize an exercise by Chris Fullmer to help us process and import USGS DEM's into SketchUp.
Sketchup DEM Import Tutorial - thanks Chris! When you finish this tutorial, export the model to a .jpg and insert in your homework document for the week.
SketchUp User Guide: 3D Model (DEM) Import - another great source of information.
STUDY QUESTIONS
- Describe a situation when a hand drawn map would serve your purpose.
- What are some advantages and some disadvantages to internet mapping sites?
- How and when are graphic design tools useful in the mapping process.
- Describe a fictious project where you would use 2 or more of the map making technologies to achieve your overall goals and objectives.
- Describe some map-making tools that were not covered in the book.
- Export your 3D terrain model from SketchUp and insert into homework document.
Start getting ready for next week by watching the following tutorials on working with Google Sketchup.
What the following videos from:
