Tips and tricks. Mode of transport: the bicycle. Basically gets you quickly everywhere, is permitted on agri tracks and in forests. Can stop at any time anywhere to record a note.

Foot: Use on difficult terrain when a bike would be a burden, or when the recording density of features is high (> 1 feature per 15 meters).

Car: Only use is to carry a bike to a remote location. Loading up the bike is a nuisance (gotta do it on inbound and outbound), and driving is not always faster, considering the "natural surveying limit" (NSL).

NSL: For me, a radius of roughly 20 km, beyond which I feel not very inclined to actively survey, because it just takes kinda long to get there (either car or bike). More precisely, the area observed is 850 km². Which I think is damn plenty.


Boom! Next village, Lenglern done.


Long time no report. Emmenhausen, Erbsen, Wibbecke, done.


Dransfeld, Imbsen, Varlosen, done.


Street lamps and other items (hydrants, street cabinets). It's really not that hard.


More street lamps are coming up. What a ride (86km; 6½hours).


Boundary stones come in various shapes. The Prussian Times ones were more standardized, obviously.


Noticed boundary stones yesterday. Today: tackle by foot. Walk 13.1 km / 4 hours. Postprocessing: 3h.


Today's objective: check two OSM Notes.
What was done: 1. The shortest way to Kl.Lengden is by going over the mountain;
2. At mtn top, rechecked a junction of paths and redrew the dataset.
3. Re-measured slope steepness on the way down. (Used better tooling this time. Curiously, the last survey here by me was 359 days ago!)
4. Some forest paths were resurfaced; new tracktype for the dataset.
5. In Kl.Lengden, noticed a bus stop is gone.
6. Noticed a new house is being erected. House has non-rectangular shape; took 5 point measurements to build orthogonals; required 6 points; guessed 6th line.
7. Validated the OSM note and its resolution.
8. Tried to leave the forest of horrible tracks...

9. Local newspaper HNA had a traffic warning about a roundabout construction zone at GVZ3. Drove there. Along the way, mapped some newly put up benches at a weir.
10. At GVZ3, took note of new roads (rough estimate, since still closed) and added them to the dataset.


Mapped all hydrants and street_cabinets from Olenhusen to Varmissen. Cycle-and-survey: 13 km, time approx 4h, postprocessing maybe 4h.
More cycling to Dransfeld; sporadic additional hydrants picked up. Observed construction progress at Zaunstätte site.
