  In earth science education, observation of field geological phenomena is very
important. Due to China's huge student population, it is difficult to guarantee
education fairness and teaching quality in field teaching. Specimens are
indispensable geo-education resources. However, the specimen cabinet or picture
specimen library has many limitations and it is difficult to meet the
internet-spirit or geo-teaching needs. Based on photo modeling, this research
builds a 3D Geo-Resource Sharing Library (3DGRSL) for Geo-Education. It uses
the Cesium engine and data-oriented distributed architecture to provide the
educational resources to many universities. With Browser/Server (B/S)
architecture, the system can realize multi-terminal and multi-scenario access
of mobile phones, tablets, VR, PC, indoor, outdoor, field, providing a flexible
and convenient way for preserving and sharing scientific information about
geo-resources. This makes sense to students who cannot accept field teaching in
under-funded colleges, and the ones with mobility problems. Tests and scoring
results show that 3DGRSL is a suitable solution for displaying and sharing
geological specimens. Which is of great significance for the sustainable use
and protection of geoscience teaching resources, the maintenance of the right
to fair education, and the construction of virtual simulation solutions in the
future.
