Description
It seems like ExportToJson is truncating floating point numbers to 6 decimal places. It would be nice if this was configurable via a parameter.
Below is the output of a geometry, one using ExportToWkt and the other with ExportToJson
POLYGON ((-177.41507893643012 28.197433657347258,-177.41548874778033 28.197776874353025,-177.415311162861911 28.197624902643991,-177.41524286097021 28.197607827171069,-177.415174559078508 28.197570261130632,-177.415092596808449 28.197491713955202,-177.41507893643012 28.197433657347258))

r22490 /trunk/gdal/ (19 files in 8 dirs): GeoJSON/CouchDB: add COORDINATE_PRECISION layer creation option to specify the maximum number of figures after decimal point in coordinates; set to 15 by default with smart truncation of trailing zeros (like done for WKT); add OGR_G_ExportToJsonEx() to accept a list of options, including COORDINATE_PRECISION; extend SWIG Geometry.ExportToJson() to accept a list of options (#4108)
