Part 1: Time Manager
- Download this data.
- Open the earthquakes shapefile in QGIS.
- Install the TimeManager QGIS plugin.
- Use TimeManager to animate the earthquakes using the time column with a time frame of one day.
Part 2: 3D maps
- Open the buildings-lower-manhattan shapefile in QGIS.
- Add a 3d view: View > New 3D Map View.
- Enable 3D rendering on the buildings layer and set the extrusion. Hold shift and drag the mouse cursor to change the perspective on the 3d view.
Part 3: Data Plotly
- Open the queens-tenancy-income shapefile in QGIS.
- Install the Data Plotly plugin.
- Open Data Plotly: Plugins > Data Plotly > Data Plotly plugin.
- Make a scatterplot of income versus owners.
- Try the box select tool on the plot.
- Experiment with some other plots, such as histograms.
Part 4: LiDAR imagery
- Open landcover.tif in QGIS. This is an extract of the city-wide landcover data available on the open data portal.
- Experiment with using the Sieve function: Raster > Analysis > Sieve, select a place to save and a threshold (say 100). This will make smaller clumps of pixels become part of their neighboring clumps of pixels.
- Right click on the original image, select Styles > Copy Styles, then paste them into the sieved layer (right click, Styles > Paste Styles).
- Build vectors out of the resulting raster. Go to Raster > Conversion > Polygonize and select a location to save to.
- In the vector layer use an expression to select only the paved areas (gray in the raster).
