[HOT] 'Something went wrong' - Can't Export GeoJSON from Field Papers

Mon Jan 29 09:01:10 UTC 2018

Hi,

I tried a workaround via the CSV export but it only works for single-tile
maps.

You can get the CSV and then use the WKT-string (MUTLIPOLYGON( blabla ))
and open that in geojson.io, this atlas:

http://fieldpapers.org/atlases/3c4a5n2o

Gives this in the CSV:

MULTIPOLYGON(((121.000020 14.585214,121.000020 14.587192,121.002662
14.587192,121.002662 14.585214,121.000020 14.585214)))

And turns to this in geojson.io when you use the menu 'Meta -> Load WKT
String':

http://geojson.io/#id=gist:anonymous/a447fd6d63453482af59446374672dd8&map=19/14.58620/121.00134

It doesn't work with multiple tiles:

http://fieldpapers.org/atlases/1jfzj837
http://geojson.io/#id=gist:anonymous/c2734d920acaee504d3324dc8ac8eaa3&map=15/13.7719/121.0631

It seems there are two bugs in fieldpapers, one in the CSV export
multipolygon and then the GeoJSON export being down.

Cheers,
Ben
