Assignment for Next Week
- Finish one of today’s visualization exercises or start your own. Some ideas:
- Visualize the provided MindRider data with 3D buildings.
- VIsualize 3D buildings with another point-based dataset from NYC Open Data.
- Use the QGIS2threejs documentation to visualize a Digital Elevation Model (DEM).
- Use Jennifer Sta. Ines’s tutorial to conduct a simple statistical analysis in QGIS.
- Finals are due in about a month. The requirements will be similar to midterms, with a possible simple analysis component. Start thinking about it!
- Install R in preparation for next week’s class. Download this sample stats file.
