The objective of the system is to produce a demonstration system of online geo-spatial data service that user can search and access the data through various methods: text search, geo-location search, and meta-data search. The applications of the data will be for any studies that can utilize these data sets.

2. Data

The data will consist of satellite images, aerial photographs (Williams-Hunt collection) and historical maps.

3. Logical System

5. Interface System

• Google Map Type using Openlayers
• Map Server Type
• Text Search (searching meta data)

6. Data access
