How could raster data from satellites be useful? Here are some ideas we had:

• During natural disasters, raster data can be useful to show where the impacted areas are. For example a recent satellite image taken during a flood can help to show where people may need rescuing.
• Sometimes people do bad things to the the environment, like dumping dangerous chemicals that kill plants and animals. Using raster data from satellites can help us to monitor for these type of problems.
• Town planners can use raster data from satellites to see where informal settlements are and to help in planning infrastructure.
