Mapping a watermill hiking trail

Sunday, May 16th, 2010
Ottenhöfen, Black Forest

Ottenhöfen, Black Forest

Around Ottenhöfen, a Black Forest town, some ancient watermills have been restored. A hiking trail connects all of them. Today’s weather was not that great, e.g. too cold for May, and it was a cloudy and windy day. We grabbed the occasion anyway, stuffed eleven people into two cars and entered the black forest, leaving the cars at Ottenhöfen station. Here’s one of the watermills:

Meanwhile I know why I’ve been elected to book and drive a van of the local car sharing provider. Along the trail, a lot of fountains are sited, and some of them act as a very special selling point (called »Schnapsbrunnen«). The black forest aborigines place bottles of schnapps in the water, add some drinking glasses and an offertory box. Hikers just serve themselves and leave some money. Needless to say that some of us served themselves very well :) .

Of course I used the occasion for some mapping. Most tracks and ways already have been mapped, but not very well. I added some ways, details along them and fixed some broken crossings. I’ve also modelled the water mill trail for appearance in the hiking and bridle map, but it will take some time until it gets rendered.

Finally we had some coffee at a local restaurant, enjoying local cake. This is a typical black forest cherry cake (»Schwarzwälder Kirschtorte«):

A great trip, and it begun raining just as we returned to the cars. An excellent timing :) .

Traveling along the french-german border

As the weather is fine at the moment (and my bike is broken again), it is hiking time. Slowly it becomes difficult to find unmapped terrain, as openstreetmap.org meanwhile does not only attract car drivers but also hikers and (mountain) bikers. In the region where I grew up a lot of medieval castles can be found, and I visited them all. Time to resurrect the hobby of my youth as long there are still trails missing in the woods.

Loosing the tracks of a hiking trip #9869

It’s not the first time it happened, but I was surprised anyway. I was hiking along the french-german border. I only ran Mæp and Waypointcatcher. I didn’t use osm2go to save some battery power. Even without Waypointcatcher not running, Mæp caused the device to crash four times. This usually happens when the device’s interface is locked, so you just notice that the device does not respond as soon as you try to unlock it. The only thing that helps is to remove the battery and boot anew. As data roaming is about 7¢ per 10KB of data (sic), I could not use AGPS. Thus the device needs up to twenty minutes to get a GPS fix after a reboot.

Unfortunately Mæp drops the recorded track after such a forced reboot. But hey, no prob, I have the WBT-201 running as a backup.

2nd Mapping Tour by Bike

Anguis fragilis

This weekend was an excellent one, providing very good weather conditions to do some mapping by bike. The Bienwald, a huge area of wood where I still seem to be the (almost) only mapper who collects data, still serves me well to combine three hobbies of mine – nature, riding my bike and mapping for openstreetmap.org.

I really love the smell of the pines during warm days in spring. You can see all kinds of animals – including crane flies, though. The Bienwaldmühle, including a traditional german restaurant, serves great food. The rest in their biergarten took too long, so the way back home included twilight – which was a good thing, because you can see even more animals (like foxes, roe deers etc.) which usually are not seen during daylight.

I collected a lot of missing ways, names of ways and names of the wooden parcels. Though it is the third year I’m mapping there, still a lot of details are missing.

I used the WBT-201 as an autonomous logger to track the whole trip. The N900 did a good job, but I left it alone until I crossed the rhine to save some battery power. This is necessary as one of my two batteries only lasts for about three hours – though I switched the device to offline mode. The two batteries have been sufficient for the whole trip, but I now know I will need a third one for whole-day-trips.

Again I was mapping using the N900. I permanently had Mapper, osm2go, FM Radio (respectively an audio player) plus a text editor running. Additionally I took a couple of photos.

The Heilbach meanders the Bienwald

I grabbed the occasion of today’s excellent weather conditions for my first mapping tour with the N900. I used it for my continued effort to map the Heilbach for openstreetmap:

I left all the other gadgets I used until now (mp3 player, Canon camera, external bluetooth GPSr, N810) at home and only grabbed the N900 to check if it really can replace the previously used armada. To anticipate the result: yes it can. I’m quite impressed and really content with the device. It’s a great digital companion. You should read on, though, to learn more about some pitfalls and shortcomings to avoid frustration.

OSM@Horizont OUTDOOR

Sunday, February 7th, 2010

Currently the »Horizont OUTDOOR« fair takes place at Messe Karlsruhe:

I’ll be at the OSM booth (which is 4.216, dm-arena, near the GPS-Village) tomorrow. Garmin maps on 2GB Micro-SD memory cards are available for sale at 10€ each (which basically is the cost of the hardware).

I hope I can share some photos tomorrow.

As Daisy had even reached the Upper Rhine Plain, we had some snow for a couple of days. I used the occasion for three nice hiking trips in the Bienwald, mapping grade 4 and 5 tracks, hiking paths and, last but not least, the stream Heilbach and some drains alimenting it:

Continued mapping of Black Forest ski runs

Thursday, January 7th, 2010

In addition to some prior mapping of black forest ski runs, I’ve been on-site again last sunday. Meanwhile, Langläufer contacted me due to my mapping activities. I’ve now tagged the route relations according to the tags he currently renders. Here’s the result as seen on his map:

Cross-country ski runs near Herrenwies

The map is similar like Openpistemap or the Hiking and horseback riding map created by Nop. Some collaboration or mashups would be great.

The winter arrived in europe, and even in Karlsruhe with its mild clime some snowflakes and temperatures less than -10°C have been detected sporadically. Surprisingly there’s not much snow at the nearby black forest yet (only about 20cm respectively 8″), but it seems to be enough for winter sport activities.

Though it was a cloudy (and rainy) day, I needed some compensation for the many extra office hours of the last week. During the winter months, I try to map hiking paths and rivers in the Bienwald, which I cannot map by bike during summer:

No posting for more than one week? Isn’t there anything interesting to write about? There is, but the release of interiorcad keeps me busy.

Due to the lack of daylight in my spare time, I decided for a short hiking trip last sunday, though it was a rather rainy day. I had good luck: The rain stopped as I reached on-site and it began raining again just as I reached the car after the trip.

A Hoverfly watching me and the bugs

Today I was tricked by my own lazyness. I have two batteries for the N810. Each of them usually lasts for up to 4 hours while being mapping. I am used to charge them immediately when I return from a mapping tour. Seems I messed it up after the last tour. As the first one was drained, I put the second one into the device – and it immediately complained that the battery was low!

Black Forest mapping between Seibelseckle and Hinterlangenbach

Monday, September 7th, 2009

It’s just good luck to live in Karlsruhe, as it is just about 80km/40min by car to get to some typical locations (like the infamous Mummelsee :) .

Day by day, more black forest tracks are being mapped by OSM addicts, but there are still a lot of gaps to fill and refinements are always possible. This weekend I have chosen the area between Seibelseckle and Hinterlangenbach.

Yesterday it began raining while being in the woods. The forecast and some webcam pics fooled me, so there was not much “outcome” concerning geo data. Today, however, it was a wonderful sunny late summer day, even allowing for some nice pictures. Here’s the area:

The track of the recently purchased WBT-201 bluetooth GPS receiver and logger IMO is again not as accurate as it could (respectively should) be. Unfortunately, I left my GPSMap at home, otherwiese I could compare the tracks. I am at least disappointed with its bluetooth reliability. Maemo Mapper often reports that it is looking for a GPS fix. The current position often is far away from the already existing objects, and if you go a way twice, the two tracks often are far apart.

But I’ll better put the typical krautish :) whining aside. So here’s the final drumroll, announcing some of the usual pics.

I really like moss closeups. It just looks a bit unnatural while it is the opposite:

Even more, though not shot properly:

I’m not the biggest fan of spiders, but I am not a chicken as many other people. I grew up in a rural area, thus being used to all kind of animals:

And finally a nice one. I managed to take a closeup of a grasshopper. Unfortunately, I could not remove the grass in front of the lens, as the grasshopper would have escaped:
