Coastal zone management is an area of increasing interest, with competing ecological, environmental and social values as well as vulnerability to our changing world. The complexity of managing the coastal zone must take into account a broad range of often conflicting interests. The use of earth observation improves the ability to monitor and forecast for such variables as sea level rise, water quality, ecosystem health, and productivity.
The benefits of mapping the informal settlement in slums has a large number of benefits. Detailing the settlement patterns allow for municipalities to provide services, such as water, sewer service and electricity. Mapping of slums provides the first step toward land governance, recognizing investments, allowing for land to be used as collateral to help bring the populations out of poverty. The mapping of the land also provides the means for setting up property taxes to offset new services.

The concept of a national map has been under review in many countries for quite a while. But the value of such a map has only recently become sharpened, clearer and more in focus. Such national maps are more than static representations. Similar to other kinds of digital efforts like building information modeling, 4D mapping and digital cities approaches, they can be vibrant, dynamic, interactive and serve as valuable platforms to support decision making from community to national levels.
