Hiking with Mapillary 2 months ago

When I have to map a lot I also go by bicycle and have a camera in the right hand. The advantage of a good compact camera is better image quality and better low-light-ability.

After having seen the Images taken by a good smart phone camera (see above) I am the more convinced that a smart phone in no regards matches my needs.
(btw: 20MP on a 1/2,3'' ccd are crazy anyway, but it seems the managers opinion is "small numbers don't sell")

Smartphone mounts 2 months ago

I was driving normally and hadn't used special settings. The phone (Sony Xperia Z1 compact" is supposed to have a "good" camera – at least compared to other smart phones.
When you look at the sequence here recorded while walking you will see that the lens is not very fast and thus some images are shaky and/or blurred. A good compact camera would handle such situations better, but it is worth a lot to have both hands free while walking.

For settings: in Mapillary you can (un)check a setting to always use autofocus, else it is fixed focus all the time. I will try the latter to see if the number of blurred images decreases. It also has the setting "Disable Stable Shot" which after its description seems to cause a higher number of blurry images if disabled. (I had stable shot enabled all the time)

Which camera for capturing 'Street View'? 3 months ago

For by-hand-geotagged photos:
You and other mappers with a fix mounted camera know that it points all the time straight forward.
But I would not assume that per default all pictures without EXIF heading flag show what lies directly in the course of the gpx track since I know my photographing behaviour when mapping house numbers, street names and alike. I point the camera where the information is I want to have. Example: Gjirokastra which I walked for three days to get all street names of the old town

I would welcome a GUI which shows the image on the one side, on the other side a map with some OSM layers and also Bing Imagery and the location of the image. Then the user would only need to klick on the map to mark the direction the image points to.
Alas my coding skills are not anywhere close to be able to write such a thing so I can just stick with begging for such a GUI…

If you think it is cumbersome to work on a load of images like this: On OpenStreetView I myself have nearly 29.000 images which I and two others reviewed and anonymized by hand – and there are some more users like me there.

For uploading to mapillary I'd like to have a easy method (FTP or a script) which I could use on a headless computer. I'd hate to have my big computer running all day just for uploading images where the NAS with a full linux could do this job as well.

I will point the mapillarians to this blog post as well so that we don't just lament but keep them informed. ;)

improper tags 3 months ago

+1

As I wasn't as experienced as I am now I also did not map everything I found after a frustrating fruitless search for appropriate tags in the OSM wiki.

Nowadays if I don't find a matching tag I pick the best matching english word for a value since the key mostly obvious, maybe add a note and also add it to a private collection of more or less undocumented tags

And even if the tag isn't approved "officially" other people can find and use or comment it.

Awesome data 3 months ago

Of course you are right. But the piece of data you displayed above has no value I can recognise…

Too slow 3 months ago

If it is just the online map loading slow you could browse the area you want to show before you present it sou you have the tiles cached. You could also use QLandkarteGT with an OSM-based Garmin map or Routeconverter's experimental branch using mapsforge¹ maps. Of course you should download the needed maps before attending the course.

Though it would be helpful if you would mention more clearly what on "the OSM map" is slow or what you try to achieve instead of complaining quite unspecific.

¹ Don't be offended by the name, it works on linux, too:

So detailliert wollte ich es nicht aufschlüsseln – möglicherweise würde sich der Eine oder Andere in seiner Privatsphäre gestört fühlen. ;)

How to Map your Trek in Nepal 5 months ago

A very good summary!

Two remarks I have to make:
with amenity:house of prayer you surely mean amenity=place_of_worship?

For not mapping streams: I agree it is not worth the effort to try to get a GPS log of its banks on-site but it is still worth the effort to map it based on aerial imagery as long as one can distinguish it from other features.

For the guest houses: if you cannot map them all, map all-¹ :)

When you make photos during trekking, you can also use them as data source for Mapping: https://wiki.osm.org/wiki/Photo_mapping

An recently developed nice app to combine photographs, mapping and Smartphones is Mapillary.
