I was just wondering if there was something I've missed to get additional visual items displayed on the SD charts (both on my PC for planning and on the iPad for Navigation).

The best example I have is the various white horses around me as whilst Avebury is noted as a VRP, the white horses aren't marked in SD but they are on the CAA charts (my 1:500,000 chart has them clearly).

As a secondary observation, the appearance of roads and rivers can be quite different - comparing the river betwen Avebury and Marlborough, the CAA map has a lot of detail (despite not being zoomable in any way) whereas the SD one is a lot of straight lines (very obvious when zoomed in).

The same is evident on the A361 between Avebury and Wroughton, there is a marked bend in the road, clearly visible on the CAA map but completely absent on the SD plot.

I understand that it needs to be sampled as straight lines, but it seems that not enough sampling points have been used to give a true indication of the river shape, though maybe this is to reduce the data footprint.

I guess as SD is being used with GPS, it is not as important to have totally accurate mapping - but as there is an option to print the route, I was a little suprised they are not that accurate...

Thanks for the reply Tim,

As a moving map for real-time navigation it is perfect and the fast update and less cluttered view is definitely a bonus.

I was just hoping to be able to increase the detail levels for printouts (even if this was an optoin on the PC only it would be useful) as having a single sheet printout with my planned route drawn on it exactly (ie matching the PLOG I have printed from SD) would be really useful as a backup should the iPad fail in some way.

I did this as a 'test' which is how I discovered this and I found it much easier to use a sheet of A4 than the unwieldy folded CAA map, which I found throughout my training that I always seem to pick up upside down or looking at the wrong side for several seconds. A single sided print of A4 is so much easier to use for a quick glance (even if the CAA map is carried in case it is needed).

However, what I found was that with the current levels of detail (and and lack of visual references, like the white horses) then I'll have to carry on drawing up the route on the CAA map. Maybe you could consider this in the future?

(Oh, along with being able to get SD to draw in plot 5deg/10deg 'off track' lines to aid estimation of closing angle)
