I have got a Garmin eTrex Legend handheld GPS unit. :-P

Managed to get 22,710 waypoints for egypt from GEOnet Name server

Loaded all waypoints as csv in Gnumeric. Clicked on chart:

Converted the waypoints file to a plucker document. Placed it on my PalmOS PDA. around 300KB only ! Sorted them using sort first. So locations near each other are near each other in the document. Plucker "Find tool" is fast enough. Not as powerfull as grep though.

Flat files rock. Linux power tools: cat, cut, sort, uniq. kick ass.

Used cut -f to select the fields i want.

I can convert them to other waypoint formats with gpsbabel

My Garmin communicates with linux flawlessly with gpspoint

wayhoo.com is down :-(

One more thing, Expedia offers very good and detailed map here is how to (ab)use them.

variables are CenP=  (Center point LAT, LONG in DDD)
              Alti=  (Altitude)
              Size=  (Image size)

Now I need a 4x4 offroader!!

UPDATE: managed to get gpsman working with my garmin. I don't why it didn't work before, may be I had some settings wrong.

eBay!

Well, thanks to the diaspora of the Egyptian workforce. You can usually find some relative crossing the atlantic, providing free shipping.

OTH, I think I saw an ad of a GPS dealer in Sudan street.

Unfortunatly

I also use it manually. I created a more readable version that can be placed on your PDA, cellphone or laptop for easier usage. It is a text file, you can use the find tool in any text editor. Will upload it and link to it in few minutes.
