D ata Store Overview <br /> Appendix – D ata Store Overview - 3 <br />about real -time data being used for important decisions and therefore such data are labeled as <br />“provisional ” with corresponding disclaimers. Ther e also may be technical issues that complicate data <br />access, such as real -time data using one identifier and historical data us ing another identifier. The use of <br />maps that include layers for stations also can complicate access because a “streamflow s tation ” symbol on <br />a map may not clearly indicate whether corresponding data are available for real -time, daily, monthly, <br />annual, or other r epresentations . Unfortunately, the different data forms can make it difficult to access <br />and use the data in an integrated analysis. <br /> <br />TSTool does not attempt to automatically merge historical and real -time data unless there is c lear <br />g uidance from a data provider. Instead, separate data stores are provided where appropriate to allow <br />access t o historical and real -time data. TSTool can display different data intervals on graphs and in <br />tabular displays ; consequently, it generally is straightforward to query and display time series with <br />different intervals. TSTool also provides commands to me rge time series int o a single time series . The <br />following ta ble illustrates how multiple data stores can be accessed to create a complete time series – this <br />is a partial list meant for illustration . Data store appendices also reference other data stores as <br />appropriate. <br /> <br />Examples of Data Store s and other Data Sources that can be Used in Conjunction to Create <br />Complete Time Series <br /> <br />D ata T ype Data Store s for Historical Data Data Store s for Real -time Data <br />C limate (precipitation , <br />temperature , etc.) <br />C oloradoWaterHBGuest (Colorado +), <br />HydroBase (Colorado+), <br /> RccAcis (USA+) <br />ColoradoWaterSMS (minute, hour, day ), <br />HydroBase (limited), <br />RccAcis (day) <br />Diversions HydroBase (Colorado), <br />UsgsNwisDaily <br />ColoradoWaterSMS (minute, hour, day), <br />UsgsNwisDaily (day) <br />Snow HydroBase (Colorado), <br />U se TSTool WebGet() command with <br />NRCS website (western USA) <br />U se TSTool WebGet() command with <br />NRCS website (day) <br />S treamflow ColoradoWaterHBGuest (Colorado +), <br />HydroBase (Colorado+), <br />UsgsNwisDaily (USA +) <br />ColoradoWaterSMS (minute, hour, day ), <br />HydroBase, <br />UsgsNwisDaily (day ) <br />Well levels ColoradoWaterHBGuest (Colorado), <br />HydroBase (Colorado) <br />UsgsNwisDaily? <br />Well Pumping ColoradoWaterHBGuest (Colorado , use <br />diversion records ), <br />UsgsNwisDaily (?) <br /> <br /> <br />The above table indicates possible sources of information , as recognized by TSTool ; however, the <br />intricacies of determin ing spe cific stations , data types, etc., are left to the software user and involve an <br />understanding of specific data offerings . <br /> <br />11
