Time Series Data Analysis
The "Time Series Data Analysis" section of this report demonstrates how to
populate, analyze, and plot time series data inside a GIS system. GIS databases do
not typically have the functionality of time series analysis. This tool enables file
storage at the gauge location within the project area. The capability to subsection
and merge files for longer time series plots or exporting ASCII files is useful for
creating boundary condition files for numerical models or other applications. This
functionality was added to the HyPAS extension because not all hydrodynamic data
collected are static in time and space.
Adding and Deleting Time Series Data Locations
To create a time series data location, assure that the time
series data theme is active, and click on the Add/Delete Time
Series Data Locations tool (Figure 5-1). The user is prompted
to add or delete a location (Figure 4-2). Choose Add a
Location and click OK. Click the specific location on
