Moon is the most fascinating oject in the sky that has stimulated so many imaginations in our human history. How many people believed that Moon was a paradise and dreamed to live there! Many people even dream of space traveling to distant planets not in our solar system as time could be expanded in fast moving rockets. Unfortunately, Einstein's time dilation has been proved impossible.

Moon is the largest object that we see in the sky. It has a close relationship with Earth. Almost all calendars in the world use the motion of Moon as a measure of a standard time period. Moon pulls the water in oceans on Earth to form tides. For scientists, the study of Moon may reveal a great deal about the history of our planet. There are many questions about Moon puzzling us: What were early conditions on Moon like? Like Earth, there is ice on Moon. Are there any lives there now or were there ever any lives existing there. Are there any special minerals there? Can Moon be used as science and research laboratories? Can we set up permenant colonies there? Are there any commercial value in exploring and developing Moon?

We want to know the answers to these questions because they are not simply of academic interest -- the need to understand our place in the universe has been a challenge to philosophers throughout the histories.

Moon is like Earth with huge amount of data that we have to collect, store, retrieve and analyze. The technologies to optimize these massive data are in developing or to be developed. However, we have to learn a lesson from Earth on which people have established very innefficient methods to represent areas and locations which have severely blocked the introduction of GPS technologies used in daily lives.

What we have now in representing locations and areas are two options: one is to use conventional addresses and place names, and the other is to use geographic coordinates such as longitude/latitude, UTM, etc. Using conventional addresses and place names to specify locations and areas has limitations: they are not available everywhere in the world (actually, conventional addresses are available at less than 1% of locations in the world) and are also language dependent. Using longitude/latitude to specify locations is blocked by the difficulties of long digits that are nearly useless to consumers (actually, consumers never use these geographic coordinates directly).

These problems have created huge inconvenience for consumers to use GIS (rely mainly on longitude/latitude coordinates), GPS (rely on digital maps that are difficult to remember and communicate) and printed street maps (rely on street indexes that are not related to geographic coordinates). Although, a very efficient system called the Natural Area Coding System has been introduced to unify all addresses, geographic coordinates, area codes and postal codes, it will take quite a long time for consumers to adopt it.

As the information from Moon is quickly reaching Earth, people should avoid the problems right at this very beginning. Therefore, we developed a system called the Lunar Area Coding System - a clone of the Natural Area Coding System. With this system, every area or location (even a 3D space block) on Moon can be uniquely represented with one unified and highly efficient code called Lunar Area Code (LAC). A LAC can be used as an accurate address for any spots on Moon, as an area code to retrieve its map or make a location based search in an area, and can be directly pinpointed on all maps with Lunar Map Grids.

If we start using the Lunar Area Coding System now, we will make all the location information highly efficient, consistent, connected and optimized.
