Hi, I'm using the windows version of osmfilter to try and extract city and town names with lat and long. The idea being to build a gazeteer for use in memory map. The command i use is osmfilter spain.o5m --keep-tags="city" --keep-tags="town"-o=mycity.osm The program runs, seems to be working but then keeps returning osmfilter error : write error I've searched using google and one other person has asked about this error but no answer was given. asked 05 Jan '14, 12:45  daveasbury edited 05 Jan '14, 13:29  Frederik Ramm ♦ |
One Answer:
You have misunderstood the The write error is likely a consequence of this misunderstanding; your command results in a file of about 9 GB and it is possible that you are either out of disk space, or even using a file system that cannot handle files that large. What you want is: answered 05 Jan '14, 13:28 Frederik Ramm ♦ showing 5 of 6 show 1 more comments |
Thanks for the reply. I've sorted the write error. You are correct about the filtering. So is it possible to filter in the form - copy one town and cities?
I've tried various examples but none seem to do what i'm after
so you want to limit your result to a smaller area?
If yes, can you define that area via a boundingbox or a boundary relation from the OSM data? like https://www.openstreetmap.org/relation/2417889 ?
Nope.
What I am attempting is to take the file spain-latest.osm.pbf which i obtained, and extract all the towns and cities contained within it as well as their lat and long. This data would be ouput to a csv file in the form
Example
Barcelona 28.00023 3.34568
benidorm 28.00034 3.90987
this I would hope to import into the program memory map navigator to create a town look up gazeteer.
The command in the grey box at the end of my original reply does just that (it doesn't give you a CSV but an OSM file with only towns and cities).
... and then use https://wiki.openstreetmap.org/wiki/Osmconvert to convert your OSM file to a CSV file where you determine yourself what elements should be in the output file.
Read that documentation in the OSM wiki and try several tags.
Thanks folks! finally sorted thanks to your replies using osmfilter spain.o5m --keep-nodes="place=city =town =village =hamlet =suburb =province" --keep-ways= --keep-relations= >mycity.osm
and
osmconvert mycity.osm --csv="name place province @lat @lon" -o=somefilename.csv
this i imported into memorymap to work with my Mobac maps and it works!
