S patial Data Integration TSTool Documentation <br />S patial Data Integration - 4 <br /> GeoView_StreamSymbols Example Map Showing Real -time and Historical Data Layers <br /> <br />The map is useful because the user and software can determine where real -time time series SHOULD be <br />available, and where historical data SHOULD be available. The mapping tools can be integrated with <br />application software by hard -coding the data type and interval for real -time and historical data or use a <br />configuration file (e.g., to indicate that “historical” data sho uld always have an interval of Month). <br /> <br />TSTool is a generic tool and therefore configuration information is required to make the link between the <br />map layers and time series. The approach that has been taken is to rely on a delimited lookup file, which <br />a llows users to determine at what level to categorize map layers. More specific information allows a <br />more specific link (i.e., a time series in TSTool can be matched with a specific feature in a map layer) <br />while less information results in a looser link (i .e., several time series in TSTool may match one station <br />and selecting the station may result in more than one time series). <br /> <br />102
