[REQUEST] Map-less geolocator
 

In many areas, cell service has only slow data connections for my phone. In such areas, maps are slow due to connect and download speeds.

Could an application be created to:
1. Take a location fix from GPS & store it
2. Alternatively, allow copy/paste or manual entry of a GPS location
3. Display a directional pointer on the screen, showing the direction of the location & its distance from the present location

without having to establish a data connection?

Re: [REQUEST] Map-less geolocator
 

I'm now trying to make such an application from scratch. As MADDE gives an error, I cannot build it on my computer and have to send it to auto-builder.

It's called:
qdialgps

0.0.1 isn't intended to work at all, it is designed to show the interface.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Error from MADDE:

libQtDeclarative.so: undefined reference to `QScriptDeclarativeClass

I'm trying to use MADDE with PR1.2 fremantle target for building Qt 4.7 program using QML.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Extras assistant:
Build failed:

error: QApplication: No such file or directory

What does it mean? It says it installed libqt4-dev as build dependency, how can it have no QApplication in its default include directory?

Just brilliant. Sending the same files to builder again.

Failed again.

Attaching tar.gz to this post.

Can somebody tell me what's the problem? I have never used QML before, but I have compiled a Qt application in this MADDE after PR1.3 without any problems.

Re: [REQUEST] Map-less geolocator
 

I believe Mappero does work offline. Also you might wanna take a look at Advanced Geocaching Tool as well as GPXView

Re: [REQUEST] Map-less geolocator
 

Advanced Geocaching Tool:
GPS view - shows the distance and direction to the selected geocache.

Mappero and Modrana can show maps offline instead of downloading them online (or you can turn off the maps and see blank background with GPS marker on it). But I don't remember any of them showing direction to a selected point.

Re: [REQUEST] Map-less geolocator
 

They don't and in IMO it is a distinct lack in the n900 GPS progs (ie. functions similar to those standard on hiking handheld GPS receivers.

Re: [REQUEST] Map-less geolocator
 

Quick reply...
Probably, ModRana will have it added, it's easier than offline routing.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For now, continuing with simple coding example.
Installed Nokia Qt SDK in order to get MADDE with Qt 4.7 and PR1.3.
Compiled qdialgps version 0.0.1.
Interface works, thanks to QML.
But, signal emitted by QML seems to be not heard by C++ program.

Re: [REQUEST] Map-less geolocator
 

That's pretty close to what I was thinking of.

But it's not adapted to quickly establishing present location for saving, &/or saving one or more "targets" for future location, like where you left your car, bike, boat, or the blue easter egg.

Re: [REQUEST] Map-less geolocator
 

I'll upload soon a new version of QLAndkarM that let you use OpenStreetmap.org and also keep map for offline use. Features are :

* Raster Map support ( Geotiff lonlat)
* OpenStreetMap.org
* Tracks
* Waypoints

Will add also position Search and Route mode from openrouteservices website.

Btw : Distance is shown from your current position to the position you point with finger on map and also Heading

Re: [REQUEST] Map-less geolocator
 

This version shows azimuth from your last known position to point (0;0).
It's updates itself with timer.
As the changes are most likely negligible, you will hardly be able to check it by eyes.
If you start from X Terminal (/opt/usr/bin/qdialgps), you can see its output.
It says:
No such signal QGeoPositionInfoSourceMaemo...
So it's hardly possible to update upon position change; timer is most likely the way to go, though it's most likely resource eater.

There is also now distance in meters.

Re: [REQUEST] Map-less geolocator
 

Now usable!
Takes coordinate at launch and then always shows direction and distance to it, updating continuously.
EDIT: it doesn't start GPS chip by itself. If you have OSMapper, Modrana, Mappero running in the background - great, they have already turned GPS on. Otherwise, the coordinate will always remain the same.
I will need to find out how to request turning the GPS on in Qt, without low-level Hildon-specific tricks.
