Landsat 5 images of Shenzhen, China. Vegetation appears red in the images and buildings are generally white.

These images show the region around Shenzhen, China from 1988 to 1996. Series of images such as these that show the same location taken over time are referred to as temporal data.

Notice as new roads, bridges, and buildings are added to the landscape in each new image. Examine changes to the coastline and the amount of sediment in the water. Look for other things that change over time in these images.

7. Describe an example of a satellite-based study that would require the collection and analysis of temporal data.

8. Describe an example of a satellite-based study that would require the collection and analysis of multispectral data.
