Re: [Announce] modRana: a flexible GPS navigation system

Got it, sorry, forgot about that extras-devel option. Still the latest version is very slow loading tracks and navigating on map.

Try yourself one of the Tour Divide maps from: http://topofusion.com/divide/gps.php

Sorry for the late answer. :)

Thank you, but I am not updating until night theme is usable in QML GUI (and mode image is used for the menu button).

The latest code in Git already has theming support in QML, just not any user interface for it just now. :) My plan is to add a button for setting the theme from QML + add your icons and then release it.

For now, a question: there ~~are~~ were hard-coded values for "layers" in both PinchMap.qml and MapPage.qml. However, MapPage.qml values take precedence, as I found out while hard-coding my preferred values of mapnik-0.5 and vaer-0.5.

It is basically like this - PinchMap is a stand alone map element/widget and MapPage is the page that is showing a full screen version of the map element/widget. Currently, only MapPage is using PinchMap, but in the future, it should show up in various places, like overview maps for POIs or search results or maybe a small "orientation" map that would show a larger area around your location.

The hardcoded values you see - the one in PinchMap is a default for all PinchMap elements and the one in MapPage is just default for the PinchMAp instance on MapPage (bit redundant as it is the same as the default for all PinchMaps). :)

BTW, as the QML UI still does not remember selected layers, you can just hardcode them in MapPage for now. Notation for the current modRana version would look like this:

Code:

        layers : ListModel {

            ListElement {

                layerName : "Virtual Earth"

                layerId: "vaer"

                layerOpacity: 1.0

            }

            ListElement {

                layerName : "OSM Mapnik"

                layerId: "mapnik"

                layerOpacity: 0.5

            }

        }

By the way, the slider for opacity can be somewhat annoying, especially when there is no way to check the exact value of opacity. Not that important, though, when I can simply hard-code them instead of going through Graphical-User-Interface.

Well, they are configured to jump by 10%, which IMHO should be a good compromise for not having to show an opacity value for each layer. Also, it should be quite easy to set stuff like 50% or to set the same value for multiple layers - there are not that many steps. Now when I think about it, just having 0%, 25% 50%, 75% and 100%, like in GTK GUI, might also do. :)

Best wishes. Will post a screenshot later, probably. I am looking for filter-negative for QML Image.

That's a good question. The negative filter in GTK GUI is using the Python Imaging Library bot something with only Qt as dependency for the QML GUI would be nice. :) BTW, I've even tried how fast it would be to do the negative in pure Python and it was about 900ms for one 256x256 tile. With PIL, it is almost instant. :)

Hi Martin,

I have compared various mapping tools exists on N900 and concluded that this is the most feature-rich and most actively developed one. However, it is slow comparing to Mappero, especially when I overlay a long track (A GPX file with 10K) makes the app and phone unresponsive. Is there any developments in this regard?

Thanks.

Zoom in. :) ModRana processes every GPS tracklog it loads internally to a series of nearby point clusters. Then it only cares about the points in the clusters that are currently visible.
On the other hand, if the whole track is on screen, it indeed draws all the 10k points. Which is arguably not very fast. :)

There is certainly room for improvements, such as simplifying the track at zoom levels - modRana already does this for the track logging trace, just not for tracklogs. BTW, now when I think about it, I haven't touched the tracklog drawing code in about 2,5 years. :D I think it is about time I do something about it. :)

Sure, good testing data is always welcome. :)

A bit busy at the moment with finishing my masters thesis. :)

BTW, last Saturday, I made modRana Python 3 compatible with these 60 commits. :D Of course it is also still fully compatible with Python 2.5 on Maemo and works just fine on the N900 as usual. :)

This was needed mostly due to the BB10 port, as there is only Python 3.2 available out of the box on that platform. Of course might come in handy elsewhere as platforms slowly migrate to Python 3. :)

Re: [Announce] modRana: a flexible GPS navigation system

modRana 0.41.1 has been released !

What's new ?

QML GUI improvements
The QML GUI now supports theming and in Options->UI (the options menu finally does something, yay ! :) ) you can enable showing mode icon on the menu button.

Android support
ModRana QML now works on Android ! Due to the Android porting work I worked on at the start of the year & due to all the wonderful improvements Aaron Richiger did on it (thanks a lot ! :)),

modRana now works on Android and can be also easily packaged for it. BTW, for more info about making Python applications for Android see the guide & the pydroid project.

The installation package is available here:
http://modrana.org/packages/android/modrana_0.41.1.apk

The package is standalone and you can just install it on your Android device as any other Android package. As it uses Qt and you have not yet installed any Qt applications on your device, it will point you to Google Play to install the Ministro Qt library manager. Once you do that, everything will continue automatically. The APK supports Android 2.2 and up, so it should work on more than 95% of all Android devices.

Please note that this package being the initial modRana QML release for Android, there might still be some rough edges here and there. Also, GPS is not yet supported, so it is basically a very fancy map viewer for now. :)

Some further notes:

after installation, the APK (Android stores them for some reason) & modRana take up together about 50 MB due to all the depndencies that need to be bundled (Python, PySide, Qt Components)
map tiles are stored in /sdcard/modrana/maps
screen size is detected automatically on startup and automatic screen rotation is supported
modRana looks really good when running on a tablet ! :)

Python 3 support
ModRana now works with Python 3, shile still being Python 2.5. As a result, it still works just fine on the N900, but should also work with Python 3.2 on BlackBerry 10 once I finally get to packaging it. :)

for comparison, the same screen with the default theme

eventually, there should be two sets of icons - black ones for the default theme and white ones for the night theme, the mode menu is the first one completely converted

Re: [Announce] modRana: a flexible GPS navigation system

I haven't used GPS on my N900 yet, but I am going to do so shortly, and I will use modRana. What an awesome and flexible program, thank you for the continued development!

Quick question: Is there a way to save maps for a specific region? Like all maps in the U.S. or in California, or within 100 miles of a specific route? And can this be done with different maps, like OpenStreet Maps and Google Maps? I don't have a data plan, and downloading map tiles for offline use would be perfect.

Thanks again for this awesome program!

Re: [Announce] modRana: a flexible GPS navigation system

There is the download button in the menu, where you can find the options for downloading maps around your location, view or route. I think it downloads the map you are currently using, so just change that to the one you want to download.

EDIT: I see this is mentioned also in the first post. Shame on me for not reading it. :o

Re: [Announce] modRana: a flexible GPS navigation system

Is there any chance of downloadable map packs for ModRana?
It can be a pain downloading around this area at different zoom levels.
In past tests if you set to download maximum amount of tiles for around my area, it slows the system down so much it becomes unresponsive.

If modRana has a i386 Linux version, I suppose this process could be done also in a PC.

I have a question, which will probably reveal my absolute lack of knowledge in this area: What modRana needs to navigate and give directions is embedded in the map data, but that metadata is separate from the graphic tiles? Because it would be a good idea to just download that metadata without downloading the tiles (or just downloading very low resolution tiles) and it seems it would save a lot of space. If you have voice navigation this would even make more sense.

Does modRana even need any tiles to be able to give directions?
