Question: I am after some mapping software for my new Garmin etrex 35 touch and am thinking of your 1:50k TOPO map of GB. I would like the 1:25K but the price difference is quite substantial. My questions are:
1) Are your maps vector or raster?
2) How up to date are the maps that you have for sale on your website?
3) Would 1:50K be sufficient to follow footpaths and cycle paths?
Answer: In answering your questions:
1) Are your maps vector or raster?
I can confirm that the Garmin TOPO Great Britain V3 PRO 1:50K and 1:25K titles both feature vector-based mapping.
2) How up to date are the maps that you have for sale on your website?
We stock the very latest version of both Garmin TOPO Great Britain map titles.
3) Would 1:50K be sufficient to follow footpaths and cycle paths?
Garmin TOPO Great Britain V3 PRO 1:50K are equivalent to Ordnance Survey (OS) Landranger maps (pink) series.
Garmin TOPO Great Britain V3 PRO 1:25K are equivalent to Ordnance Survey (OS) Explorer maps (orange) series.
Please check to confirm which level of detail you require. The Garmin TOPO Great Britain V3 PRO 1:25K map features both the 1:25K and 1:50K maps. The 1:50K is pixilated beyond the included 1:50K map scale.
