| Observed data are stored as part of the attributes of a feature point in the GSSHA and the GSSHA Storm Drain coverage types. Click on the button in the ''Observations'' column for any feature point/node in the ''Feature Point/Node Properties'' dialog to access the ''Observations'' dialog.

| Observations can be stored for data comparison or can be used with the GSSHA automated calibration algorithms. If you are not running an SCE-based calibration, observation points can be defined anywhere in your model. GSSHA will run an automated calibration using your observed time series data if you have the Auto-calibration toggle box turned on for a calibration. The auto-calibration option is only available for certain types of observation types. Channel-based observations can only use the auto-calibration option at nodes on streams in your GSSHA coverage. Tile drain discharges can be calibrated by defining the observed discharges at junction nodes in the GSSHA Storm Drain coverage.

| Observations are managed using the '''Add''' and '''Delete''' buttons in the dialog. Specify the observation type by choosing from any of the gridded or link/node datasets that GSSHA can output. Click on the '''Define...''' button to enter the observed data in the ''Define GSSHA Observation'' dialog. The dialog gives the option to define the observed data using the [[WMS:XY Series Editor|XY Series Editor]]. It is optional to associate the observation with a specific rain event (GSSHA rain gage coverage) if multiple events are defined. Both the link/node numbers and the I, J values of the cell encompassing the feature node are displayed in the dialog.
