The main UK turning point file is split into several regional files, but these also contains turning points that you possibly won't need. For example, the southern regional file contains 7 entries for Lasham, including competition start points. Unless you fly competitions from Lasham, you will probably only want the main LAS turning point.
TpSelect allows you to specify a particular location (for example your home club site) and to select turning points from the main file that are within a certain range of this point. You can then review the list of selected points and add further points or remove those you don't need.
When you save your final selection, this is written to a file in any one of a number of different formats, depending on your model of GPS, or the download program that you use.
To remove the program from your computer, go to Add/Remove Programs in Control Panel and click on the TpSelect entry.
At periodic intervals you will be reminded to check for updates (you can turn off this feature if you prefer).
