InteTrak Structural Model: Networks and Processes

InteTrak is structured to focus on two main project types: networks and processes. This distinction allows InteTrak to embrace a model of a single physical network feeding multiple processing treatments.

• Network projects are strongly tied to the physical GPS field network, especially its GPS hardware, communications hardware and output GPS data streams. Stations are configured, data streams are manipulated, and data are archived with little regard to how the data will be applied.
• Processing projects are independent collections and treatments of GPS remote and reference stations, processing spans and processing parameterizations. Processes are only limited to the station combinations and measurement data available from a source network.

This partition reflects a physical and operational distinction between a field network and that network's data processing. Beyond ensuring that raw data are collected at a minimally useful rate for a chosen processing method (i.e. a 5 sec. interval for kinematic or a 30 sec. interval for static), network data streaming is essentially independent from data processing. For example, a process can be run using any subset of a network's sites. Processing techniques can be modified to account for changing project goals and requirements.

The network/process structural distinction is first encountered in IT_DBConfig when the user is asked to select a project type. It is further exhibited by the independence of process and network projects within InteTrak. There is little, if any, dependence beyond the data shared through the InteTrak database.

Processing Projects: Tracking and Post-Process

Processing projects are further subdivided into tracking and post-processing types:

• Tracking processes typically run in unison with network projects, processing the latest incoming GPS data for near-real time displacement monitoring.
• Post-processes run independent of actively streaming networks and are designed for re-processing archived GPS measurements to perform focused analyses, improve positioning results or experiment with processing techniques.
