Hi Marc (or anyone else),
As suggested by Michael a while back, I am scanning the globe once a week
for water fountains (modern and historic) in a nested loop of bboxes. After
getting all the individual scans, I append them into one large geojson file
.. I scan for fountains with a bbox size of 10x10.
I seem to get a faster response using overpass turbo at overpass-turbo.eu
using the web interface than with the API. Is this normal ? The total size
of the all the responses combined in one file is relatively small : about
50MB (after appending them all in one json file).
It takes me on average about 3 hours to get all the data I need for my
database. Do you have any suggestions for how I might improve the
process? Or maybe, what I am doing seems ok ?
Thank you for your advice,
// print results
