Here are some details of the hardware and software that I use. The links will take you to the relevant web site.

When walking I use a Garmin eTrex Legend, but I prepare my routes and save my tracks using Memory-Map Navigator which uses 1:50,000 scale Ordnance Survey maps. Memory-Map Navigator runs on my PC, which is a Dell Dimension 8200 with the Windows XP Home Edition operating system.

When driving I use TomTom Navigator on an iPAQ 3970 with an Emtac Bluetooth GPS. The iPAQ has both SD and CF cards, the latter being installed in an expansion jacket.

Being a retired scientist/aeronautical engineer I write my software in the Fortran programming language, which I started to use in 1969. The compiler is Digital Visual Fortran 6.0 and I use the Winteracter Fortran library, version 5.10, to create programs that will run under the Microsoft Windows operating system. The qtXLS library is used to read and write Microsoft Excel spreadsheet data. Help files are created using DotHelp version 2.30, and TextPad is used for creating and editing text files. With this software, and years of experience with Fortran, I find I can quickly put together a new application.

At the end of 2003 I started to learn C++ and I have now rewritten the eVB version of POIManager for the Pocket PC using eVC++ 3.00 and MFC. It was quite a steep learning curve; and it has reinforced my belief that Fortran 90 is a very well thought out programming language.

The best site for keeping up-to-date on GPS matters is Pocket GPS, where I appear as Oldie in the forums. I am also grateful to Pocket GPS for making my programs available for general use in the Downloads area of their web site.
