Is there a way to move your location using the geopoint with map widget? It
seems like it's only used to visualize your location, at present.
Is it possible to use another map provider (i.e. openstreetmaps)? what are
the implications of using google maps on privacy and data ownership?
What accuracy level is "good enough" for what when it comes to geopoints?
There is some code written to support touching your location on the map and
returning that location. It is currently disabled, as it is unclear
whether the display should be interactive or read-only.
Currently, the widget uses com.google.android.maps.MapView and is therefore
limited to whatever providers work with that.
Geopoints are stored as a location + accuracy, so the level of accuracy is
really up to your app to define. Unfortunately, Javarosa provides very
poor support for interpreting and testing the accuracy or location elements
of a Geopoint.

Hi Mitch
we would like to use a pin on a map-feature as a back up for the gps, which
seems to be a bit shaky at times. So an interactive Map would be desirable.
(the app Swiss Grid is a nice example). In addition, the map should be
usable in offline mode, like offered in google maps.
Curious to know how close you are to possibly providing such a feature.

We are not working on this feature. Code contributions are welcome.
With ODK Collect 1.2, we have the widget that displays the coordinates on a
map. (appearance="maps").
I'm not sure how hard it would be to enable a user to drag the pin around
and return the new location. Also not sure if anything needs to change to
better support offline-cacheable maps.
It is questionable whether Google Maps is the technology to use, or if this
should instead be a widget that records the x,y pixel coordinates off an
image, perhaps with conversion equations to geocoordinates (or not).

I now use the following work-around for the problem getting location
information from a map (without gps):
This seems to be an ok back-up, albeit without direct calculation of
coordinates (we are primarily interested in uniquely identifying objects -
coordinates are just one means to do so). The apps that do provide
coordinates on tap don't seem to offer offline maps (e.g. Swiss Grid), as
far as I can tell.
Curious to hear if and how others have tackeled the issue.
Cheers
Thomas
