#5 Updated by Alessandro Pasotti 6 months ago

Is it the attached file a direct ogr2ogr output?

The encoded jsonarrays look wierd to me:

this is not valid json:

{EC,ER,MA,PH}

it should probably be

["EC","ER","MA","PH"]

#6 Updated by Mickaël CALLAC 6 months ago

The dataBase SpatiaLite output is an export from a DB PostGis by ogr2ogr.
The fields in PostGis are typed in array (character varying []) and contains value which look like {EC,ER,MA,PH}, ogr2ogr keep the same format in the spatiaLite database.
