Browse Geocoded Results with Corrections
As with any other dataset or printed list, the Spectra tables that are used to create the callbook will invariably have a small number of address errors and misspellings: these can be easily spotted and corrected in the 'Browse Non-Geocoded Results' page, with probable corrections suggested automatically. Some have been done for you already. Errors are filtered out of the database results, and stored separately. The 'Browse Geocoded Results with Corrections' page shows all callbook entries that do not contain errors that stop geocoding, and also includes all entries for which corrections have already been made. If you want to see callbook entries that never had errors, view the 'Browse Geocoded Results without Corrections'. To see errors that still need correcting, see the 'Browse Non-Geocoded Results' page. To see corrections that have already been made, see the 'Browse Non-Geocoded Corrections' page.
Call listings can be sorted alphabetically by callsign, licence-class, licensee-name, address, suburb, state, postcode, latitude, and by longitude. To perform a sort, click on the desired column-header.
The Latitude and Longitude values for each call are not included in the Spectra dataset. They are obtained, instead, by matching their postcode and suburb details with supplied values for those postcodes. See the Geocoding help-page for more details. Once a position has been obtained, the callsign can be plotted on the maps, and have their position compared in a 'Spatial Query' with the position of any of the many other data-entities in the supplied tables, or in your own lists and logs.
Callsigns can be plotted on two types of map: the Online Map and the Overlay Map, using a variety of different markers. You can choose which marker is used by visiting the Options Menu. There are 37 different markers available. To plot a callsign on a map, right-click the desired line in the table and choose 'Show on Map' from the context-menu that appears. The selected tab-page will change to 'Online Mapping', and a coloured marker will be added at the position corresponding to the latitude/longitude values in the table. An identical marker is also added to the Overlay Map.
Markers plotted on the Online and Overlay maps are contained within 7 different invisible layers, each of which can be turned on and off or cleared individually. Callsign markers have their own layer, so any plotted Callsign markers can be hidden temporarily, or permanently cleared from the Online and Overlay maps without affecting any other markers or polygons currently displayed. To control the Callsign markers, click 'Markers > Hide Callsign Markers' or 'Markers > Clear Callsign Markers'.
If you would like a copy of a line in the table, right-click and choose 'Copy to Clipboard' from the context-menu that appears. The relevant line is then copied to the system-clipboard, and you can utilise this data by pasting in 'All Programs > Accessories > Notepad' or any other programme that accepts copied text.
If you would like to copy the entire table, in its current order, for use in an external program, click 'Export > Export Table to CSV File', and save the file at a desired location on your computer.
Assuming that you have entered your QTH's latitude and longitude position by clicking 'Help > Options > Mapping > User Details', you can then perform a 'User Spatial Query' on the table data by right-clicking any table line and choosing 'User Spatial Query'. What this command does is to order the complete table by distance from your User-location. You can thus discover the calls that are the closest to you, and those farthest way. A 'Bearing' column is also added to the table, that shows the short-path bearing from your User-location. If you wish, you can order the table by bearing simply by clicking that column's header. Note that making Spatial Queries does not alter the data in the databases in any way.
The next option in the context-menu shown when you right-click a line is 'Row Spatial Query'. What this command does is to order the complete table by distance from the location of the call in the row that you clicked on. It is similar to a 'User Spatial Query', but instead of using your home-position as the base reference, it uses the geocoded position of the callsign that you clicked. You can thus discover the calls that are the closest to that particular call, and those farthest away. A 'Bearing' column is also added to the table, as before.
