摘要：Though remotely sensed satellite imageries are increasingly accessible to Geoinformatics societies, the disparity between spatial grid in satellite data and geographic information are needed to coordinate for the societies. The coordination will be effectively eased to apply to the societies. On the other hand, the development of web technology is enhancing the information technology more advantages. Three databases are established for validation field. The establishment of the validation field for satellite remote sensing will be very useful for the societies to coordinate geosciences researches. The databases are GCP database, mountain tracking database and vegetation spectral database. Above 500 GCPs are collected together with photographs. The GCPs cover the area of about 20,000 km 2 and are widely spreading throughout the Shikoku, Japan. The mountain tracking data are collected by hiking the peaks of Shikoku Island's mountains. Useful data are collected along mountain tracking such as collection of waypoints with photographs and surrounding land-cover information and tracking the route. All mountain tracking routes are archive after the field excursions. For vegetation spectral database, sample trees leaves photographs and their spectral data are collected using spectrometer under the laboratory condition. Weekly data are achieves from these data. Amount these three databases, GCP database and mountain tracking database are completed to open web-publication while vegetation spectral database is on the implementation stage. The databases are published through the internet to all societies with free of charges. The important beneficial contribution of the works to the societies are GCP database can improves satellite image registration and geometric correction, mountain tracking database can helps validating the satellite image classification and vegetation spectral database can apply in validation of spectral classification methods. Thus, these works filled the gaps of three corners of Geoinformatics which are extremely requires by the societies in raster and vector integration. Moreover, the procedures on field work management, field work scheduling and group trip planning were indirectly benefits to the students and researchers of host institution
