Geo-information Integration Based On Google Earth

Geoscience research often needs to integrate multi-class, multi-source data, information and material to make the comprehensive judgment. Multi-source data integration plays an important role in geosciences field. The thesis presents a geo-information integration system based on Google Earth digit earth platform. It takes the oil and gas exploration data at Longmensha mountain region as example.The thesis introduces the virtual realistic technique, concepts of digital earth, Google Earth platform and KML language. It also briefly introduces the geological and geophysics research situation of Longmenshan mountain. The main achievements of the thesis are as follows:(1)Develop a framework to carry out geo-information integration based on Google Earth.(2)Develop a geo-information integration system for the integration of oil andgas exploration data at Longmenshan mountain. The system has the functions ofgeoscience data associated with the placemarks, image overlay, database connection,software integration, etc.(3)Develop a technique to show or hide placemarks according to the differentview altitude.(4)Develop a technique to converts Maplnfo data into the KML form.
