Abstract

According to land spatial data sharing demands, study the relation for special data transmission velocity on-line and data quantity by experiments in this contribution. It has educed some valuable conclusions through analysed the result of experimentation of the on-line land spatial data piecemeal transmission experiment. When transmission's block data size of the land spatial data is in the 1MB scope, the each time transmission's speed time is the shortest when the block data size is 8KB.Certainly,the transmission's speed time is Not too discrepancy when each time the transmission's block data size is between 4KB and 32KB. When transmits the land spatial data size between 1MB and 200MB, the block data size which waste the least transmission time is 32KB. When transmits the land spatial data size around 350MB, the block data size which waste the least transmission time is 512KB.
