MoNav@FOSSGIS 2011 fair, Heidelberg, Germany

Sunday, April 3rd, 2011

FOSSGIS is a non profit organisation and represents both the local chapter of OSGeo and the german OSM community. This year’s conference takes place in Heidelberg, Germany.

Besides other talks, Christian Vetter and Dennis Luxen, the propellerheads behind MoNav and OSRM respectively, offer a talk about their products.

Routino Frontend published

RoutinoFrontend

RoutinoFrontend

I’ve just released Routino Frontend to the world wild web. The current code needs manual installation. A proper installer will be created only in case I see there’s some interest in this application.

Routino Frontend will start the GPS subsystem and allow you to get the current GPS location as departure or destination. Additionally, up to three via points are accepted.

To get the coordinates for via or destination points, go to Mappero, point the map to the desired location, press the left uppermost on-screen button, choose »Show Position« and copy it to the device’s clipboard.

After a route is calculated, the resulting file will be placed in the documents folder of the device, ready to be loaded into Mappero or Maep.

The code is in its early stages and needs refactoring. Please note that the current frontend will invoke routino in blocking mode. As soon as you process a route, Routino Frontend will not return before it finished. In case you calculate a long route, this means that Routino will eat all your CPU, memory, swap memory and battery power until it has done its job (which means that you probably need to remove the battery to quit it).

If you are more familiar with Python (and especially its subprocess module) as I am and you can help to add a nice cancel button which reliably kills Routino please drop me a line.

Waypointcatcher resurrected for Maemo 5

Waypointcatcher on Maemo 5 (aka Fremantle)

Waypointcatcher on Maemo 5 (aka Fremantle)

As the location API has changed in Fremantle from libgpsbt to liblocation, the previously released version of waypointcatcher won’t do the job on the N900.

I’ve thus updated the python code, which despite its C&P nature just »works for me«. I’ll share the application on request, until I find the time to do the necessary cleanup and to offer a proper point and click installation link.

Its main purpose is to collect waypoints for openstreetmap, as Mapper does not record marks reliably ATM.

SRTM tiles available online

SRTM contours in Navit

A couple of days back, I converted the SRTM dataset into tiles containing OSM contour lines. Meanwhile the tiles are available online. This service is provided by the Stuttgart University of applied Sciences, thanks to the support of Dr. Franz-Josef Behr.

I hope the data is useful for some community work, e.g. tile rendering for slippy maps or rendering contour lines into viewports of mobile devices. If you create publicy available stuff from the data, please drop me a line.

The current issue 12/2009 of the german »Linux Magazin« features several GPS related articles. On page 40 there’s one about Openstreetmap on mobile devices, especially the N810.

Since today, EGNOS is officially up and running. I’m pretty curious whether this will improve the accuracy of positioning data received by my GPS toys.

Gebabbel available for openSuse

Andreas Schneider, who also seems to be an GPS enthusiast, just told me that Gebabbel is available for openSuse. The application’s page still does not exist but shoud materialize within a couple of days.

Continued roman highway mapping

Sunday, April 26th, 2009

More or less I have finalized the mapping of the remains of the “Via Rhenana”, an ancient roman highway. The visible remains start in Berg and end south west of Jockgrim. I read about some minor remains in Rheinzabern and near the Zirkerhof (which is still missing in OSM), but I’ll leave it up to true archaeologists to enter more details of the trail :) .

I still find it surprising that its stretch is not as straightforward as usually assumed, especially as there does not seem to be any topological need for the deviations. Maybe they have used existing trails, but if so, I wonder why they followed them without any need. Building a roman highway was expensive, both in terms of money and labour.

“Landgraben” in Karlsruhe now part of the openstreetmap data

Sunday, April 26th, 2009

landgraben.png

Based on a description of a local Wiki, I have added the Landgraben to the openstreetmap database. It’s an old ditch, started back in 1588. Nowadays it’s completely covered in the inner city and part of Karlsruhe’s sewer system. It still gives some places and streets their unique look and (often triangular) shape, like the Lidell- and Ludwigsplatz or the Sophienstraße.

Global Positioning in 1915

Shorpy has a nice “poser” image of workers in the “U.S. Geological Survey engraving room.”. What was openstreetmap like in those days :) ?

Ruby script to convert waypoints to MaemoMapper POIs

Tuesday, February 3rd, 2009

I’ve just written a small Ruby script which can convert GPX waypoints to a sqlite database file to be used in MaemoMapper. The next time I get surprised by some rainy clouds while riding my bike in the forests, I will at least know where the next shelter can be found:

If you need some material to play with the script, I have just updated the POIs for europe as well. Hope you like it.

Drone Gadget for Openaerialmap

Tuesday, January 27th, 2009

If you think that openstreetmappers are people who spend lots of money for their GPS toys, there are similar projects which require even more expensive gadgets :) .

GroundTruth Released

Monday, January 26th, 2009

Igor Brejc just released GroundTruth, yet another tool to create Garmin maps from OSM data.

A brief overview about the history of map manipulations

Wednesday, December 10th, 2008

Ever wondered why there is no usable map material for your favourite holiday location? Süddeutsche.de, the (german) web presence of the famous »Süddeutsche Zeitung«, provides a brief overview how maps have been manipulated over the centuries.

Mapping housenames in OSM

Tuesday, December 9th, 2008

Housenames (aka numbers) are important to do proper geocoding of addresses, e.g. for routing applications. There’s the Karlsruhe Schema which defines one approach how we could do it. (more…)

Routable Garmin maps from openstreetmap data

Sunday, December 7th, 2008

The main reason why I started contributing to openstreetmap was the fact that there was no geodata (neither freely nor commercially) available which fulfilled my needs as a cyclist. (more…)

Waiting for the german government to contribute geodata to OSM

Sunday, December 7th, 2008

On Thursday, the german »Bundesarchiv« (German Federal Archive) announced that they will donate about 100,000 images (mainly related to the german history) to Wikipedia Commons. Of course, that’s really great news. But even better, this confirms us over at openstreemap.de in our perception that german authorities will contribute their geodata to openstreetmap – one day. In the meantime, we still have to do the hard work manually until we become widely accepted as the “Wikipedia of geodata”.
