The current version is not handling RHR correctly, but seems like @rurban made a fix (see #81)
According to RFC 7946, exterior rings are counter-clockwise, and opposite for interiors.
Would be nice to have this merged to master, and publish a new NPM (the latest version there is 2.0.0)
Here is a sample MultiPolygon that should be correct, but fails validation:
{ "type":"MultiPolygon", "coordinates":[ [ [ [ -149.92383493947585, -107.20901451037372 ], [ -259.59381502763006, -109.20301414834012 ], [ -258.2644819356524, -134.460342895915 ], [ -203.09715861858095, -141.77167490179193 ], [ -140.61850329563254, -125.81967779806041 ], [ -149.92383493947585, -107.20901451037372 ] ], [ [ -254.4534848633285, -128.68537469897 ], [ -252.63985750747375, -113.16878509887954 ], [ -241.1746460656409, -113.77221728002854 ], [ -239.54032744438703, -128.88966452662675 ], [ -254.4534848633285, -128.68537469897 ] ], [ [ -211.55262105541485, -114.18079693534207 ], [ -198.47807208538396, -125.41673745646227 ], [ -222.17569209356486, -126.02960693943254 ], [ -211.55262105541485, -114.18079693534207 ] ] ], [ [ [ -217.05515608434595, -92.58635049861982 ], [ -241.64781828593203, -65.33502211307837 ], [ -263.58181430356285, -92.58635049861982 ], [ -217.05515608434595, -92.58635049861982 ] ] ], [ [ [ -154.57650076139757, -62.01168938313447 ], [ -190.46849424479345, -62.67635592912325 ], [ -190.46849424479345, -92.58635049861982 ], [ -150.58850148546466, -95.24501668257506 ], [ -154.57650076139757, -62.01168938313447 ] ], [ [ -183.15633501112902, -68.82845519554763 ], [ -161.2973234518588, -68.82845519554763 ], [ -160.48016414123182, -87.2145396846534 ], [ -183.36062483878575, -87.2145396846534 ], [ -183.15633501112902, -68.82845519554763 ] ] ] ] }
@oyvindi confirmed. Thanks for the example. I will add it to the test suite.
