Abstract: Surveying and mapping metrological verification is an important measure to ensure the accuracy and consistency of surveying and mapping measuring instruments, and it is also an important form of value transmission or valuetraceability. However, at present the metrological verification management software is only limited to the business process, and ignores the digitization, networking, automation, data sharing and later data mining of the metrological verification process, which cannot a greater role in metrological verification in the society. The cloud platform for collaborative work of surveying and mapping metrological verification introduced in this paper uses a cloud server as a carrier and adopts a B/S architecture mode to move all verification services from offline to online. The application model of big data for instrument verification is established and a new mobile interconnection mode for surveying and mapping geographic information metrological verification services is realized.

Key words: surveying and mapping measurement, verification, synergism, B/S architecture, cloud platform
