Zoomable maps

Hi Tom,

When you display records (eg tetrad counts) on the zoomable map the roads are initially all white. If you then switch to satellite, and back to maps the main roads become yellow - which is much more useful. Could this be set as the default zoomable map?

Hi Jon,

Good idea, I'll investigate. A problem with relying on Google maps is that they are free to change things and do so quite frequently. I'm not sure when the two map variants started appearing - it didn't used to be like that.

regards,

Tom

Hi Tom,

The original comment in this thread still applies (about the road colours), but here is another point regarding the zoomable maps. I can't see any way of plotting county boundaries on the zoomable map. If you go to a printable map then you can switch on the boundaries, but you then can't zoom in. I've wanted to do this a few times in the past, but particularly wanted to do so with the publishing of the new Flora of Cambridgeshire, which doesn't have distribution maps. Whilst I can generate a county distribution map from the search page, I'm not sure that this is available to members more widely, and in any case it isn't a simple button push. I'll leave you to decide what the priority should be on this.

Regards, Jonathan

Hi Jon,

Thank you for this suggestion. I think that a revamp of parts of the mapping software is overdue, particularly if we increasingly emphasise use of the DDb (and linked systems) for data entry.

I need to find a better optimised way of plotting boundaries, the approach currently used for the zoomable maps fails once the boundary line becomes too complex. Instead an overlay of pre-rendered tiles probably ought to be used.
