TSTool Documentation S patial Data Integration <br /> S patial Data Integration - 9 <br />To support this functionality, the attributes for the layer should include a column for the location <br />identifier , and optionally the data source, where the values match the values shown in TSTool. <br />Additionally providing an attribute for data interval allows another level of selection. In this case, the <br />intervals in the attributes must match those shown in TSTool. Providing all information will result in <br />record -level queries that allow a direct link between a time series and a layer. <br /> <br />7.4 Using Locations on the Map to Select Time Series <br /> <br />To select time series from the map: <br /> <br />1. Perform a time series query to create a l ist of time series (see the previous section for an <br />example). The map can be used to select time series in this list, but selecting from the map <br />will not initiate a database query or file read. This is because the variety of input types that <br />TSTool suppor ts require specific information to query/read time series . <br />2. Select a layer of interest on the map. This layer should correspond to time series in the list from <br />the first step. For example, if the time series list contains daily streamflow time series, sel ect the <br />map layer that corresponds to such data. For example: <br /> <br /> GeoView_SelectLayer <br />3. Activate the select tool on the map interface toolbar: <br /> <br /> GeoView_SelectLayer2 <br />4. Draw a box around features of interest on the map. The software will attempt to match th e <br />features in the time series list in the TSTool main window. To do so, it first matches the layer <br />name with the similar value in the lookup file. It then tries to match the ID (and optionally Data <br />Source ) values in the input/query time series list with the attributes indicated by the <br />Layer_Location and Layer_DataSource lookup file (Layer_Interval can also be <br />used). Matched time series are selected in the list. Previous selections are not cleared – use the <br />right click popup menu to clear selections firs t if appropriate. <br /> <br />107
