But in the maybe pile:
Speed indicator (knots)

Moon phase (info screen or search)

Tides (info screen or search)

Weather (info screen or search)

Distance (point to point)

OK, everything ticketed

I've been thinking about adding a 'go to' button to the main menu, which would basically do this/other things like:

go to->coordinates->enter coordinates
go to->POI->select poi

etc.
+ clickable "go to" widget.

As RR is really just a collection of POI's with a proximity algorithm and an interface to alert the user when he gets within 'x' Km's of any individual POI, I wondered whether it would be possible to build this into a future modRana release?

It would be nice to have a prominent icon displayed on screen and/or an espeak prompt warning of any speed cam's on the upcoming stretch of road. Would take modRana one step closer to emulating a dedicated in-car navigation system. Thoughts?

There is already a ticket for this:

Code:

 * activate from POI -> tools menu
 * set:
  * distance
  * espeak message (recorded sound ?)
  * repetition -> once/twice/every N seconds while in perimeter
  * optional -> a message for leaving the perimeter
  * optinal -> say the current distance as part of the message
 * multiple distance/message pairs for a POI

 * possible uses:
  * speed cameras
  * fishing spots
  * reminders ("you are near the supermarket, don't forget to buy X")
  * geocaching/treasure hunting

Any ideas what else it should do ?

The GUI mockup looks good!

BTW, is there some marine related reason for all the white color ?

This is a known issue (Czech street names pronounced with English pronunciation sound silly, trust me

), the driving directions that are provided by Google are just html formated strings and the street names are not delimited in any (parsable) way. But it might be possible to do the future, with some other routing service that provides more granular directions, preferably with street names that have language codes

Thanks for the pointer! Should be quite simple to integrate

Well, Woody is currently cooking a on-device tileserver, so I would say that things are moving in the right direction

A question in another thread brought the fact that the n900 really has no hiking GPS app ala a garmin or some such handheld.

PS Apparently Advanced Geocaching Tool has direction and distance.

I can see a few ways of representing this:

big fullscreen arrow and distance (like in AGTL)
a widget version with small arrow and distance, placeable on the map screen (I really have to finally rewamp the widgets to a usable state )
an arrow pointing from the current position indicator (TangoGPS does it like this)
just drawing a long line from current position to a given point
or maybe drawing your own route on the map (might be also useful to send to others) ?

Full screen and moving
Moving
Receiving GPS data
never
Always
cheers

OK, I guess I can also do this like this once the basic screen blanking control is in place

I didn't have time to check closely but I suspect RR possibly wasn't updating GPS co-ord's correctly either.

I had assumed that multiple app's would be able to concurrently access the GPS without interfering - apparently not, unless I did something wrong during the test.

This is indeed strange as both modRana and RR (most probably, did't look to the RR source yet) use Liblocation, which should is provided especially to enable concurrent GPS access.
What was the position indicator in modRana doing ? Stuck in place or rotating or something else ?

Basically, yes

For start, some samples of the actual SMS Google is sending would suffice + a check if they all come from some special number

But once I have something that might work, a US based tester would be needed

Any chance the same dataset could be also used for routing (in the future) ? Like for example, by pgRouting, that claims to provide routing for postgres ?
