Under the TIN Node, any TIN data that has been loaded will have a TIN File Node. These nodes provide some information about the individual images, including the interval, the source file/DSS record, and if there is missing or overlapping data. Missing data, overlapping data, and metadata abnormalities are indicated by icons, and shown in the table below.
Icon | Description |
| This is used for TINs that have the expected relation to the other TINs in the dataset, and no timespan anomalies were detected in the metadata. |
| This icon indicates that the TINs either has an overlap or a gap with respect to the other TINs in the dataset. Instantaneous data does not use this icon for feedback. |
| This indicates there is some problem with the TINs metadata. The most common issue is that the metadata encoded times do not match the DSS pathname time. |
| This is used when the TINs could not be located. One example is that one of the TINs that was selected by the Data Reader has since been deleted. In this case, the HEC-MetVue was told to read a specific file or DSS record, but that file or DSS record no longer exists. |
In addition to the icons, hovering the mouse pointer over the path of interest will display an informative tooltip that will help further with diagnosing the problems with the data series. The files/paths displayed in the Project Explorer window always use the display time zone for the project or session. For DSS, this is not necessarily the path that was actually read from the DSS file, as the read time zone and the display time zone can differ. The tooltip shows the actual path read from the DSS file to help make it easier to diagnose data issues which may require other programs such as DSSVue. The most common issue is that the timespan encoding in the DSS metadata does not match the timespan in the DSS pathname.



Read Constraint Identification
The TIN Node also indicates the read constraints used to read the data. These are noted in the image below, where TZ is the Time Zone Override (N/A indicates no override), TC is the Temporal Combination Method (Agg indicates aggregation), the Spatial Combination Method (N/A indication there is no spatial combination), and EC is the Extent Constraint (No indications that there are no extent constraints).

If used, the Time Zone override will be noted with the three digit Time Zone Identifier. The Extents Constraint is either "Yes" or "No" in the TIN Node, and the data selector must be opened up for details on the constraint. For the Temporal and Spatial Combination method, the table below details the different abbreviations:
Abbrevations | Combination Method |
---|
Agg | Aggregation |
Avg | Average |
AvgX0 | Average ignoring zero |
Min | UseMin |
Max | UseMax |
