The Hydrography Event Management (HEM) Tool provides full functionality for adding and editing events in the NHD.
Events are informational data that are linked to the NHD using a linear referencing system on NHDFlowlines.
The use of events is a key characteristic of the NHD by allowing vast amounts of scientific information to be linked to the NHD while keeping the design simple and by making advanced analysis techniques possible.
The HEM tool handles all the linear referencing mechanics to make working with events easy.
A Source Feature ID is created that provides the link between the event location and the informational data tied to the location. It also creates metadata linked to the event.
The tool also provides network measuring to determine distances through the flowline network.
