The following descriptions of survey phases show an example of using networks and import events with survey data.
- A survey is being done on a parcel of land by multiple survey crews. The survey will be analyzed within a single survey network, for example a least squares network analysis.
- The data from each survey crew is downloaded into separate .fbk files and each .fbk file is imported into the same network, creating a separate import event. During each import, potential point identifier (point name or point number) conflicts can be resolved by applying a point identifier offset, and linework can be processed using the specified linework code set.
- The network is analyzed creating adjusted control points for each setup and updated coordinates for each sideshot within each setup. The coordinates for each figure are updated in each import event.
- In a later stage of the civil engineering process, an additional survey has to be performed to establish control for construction stakeout of proposed roads and parcel corners.
- This additional survey ties into the network that was adjusted in phase one and also requires a least squares analysis.
- A new network is created, and for each survey data file that is imported into this network an import event is created.
