ArcGIS JSON with multiples paths for feature is not parsed well to GeoJSON

[ethervoid]

I have a JSON from ArcGIS this way:

{"objectIdFieldName":"OBJECTID","globalIdFieldName":"GlobalID","geometryProperties":{"shapeLengthFieldName":"Shape__Length","units":"esriMeters"},"geometryType":"esriGeometryPolyline","spatialReference":{"wkid":102100,"latestWkid":3857},"fields":[{"name":"OBJECTID","type":"esriFieldTypeOID","alias":"OBJECTID","sqlType":"sqlTypeOther","domain":null,"defaultValue":null},{"name":"Id","type":"esriFieldTypeInteger","alias":"Id","sqlType":"sqlTypeOther","domain":null,"defaultValue":null},{"name":"NAME","type":"esriFieldTypeString","alias":"NAME","sqlType":"sqlTypeOther","length":50,"domain":null,"defaultValue":null}],"features":[{"attributes":{"OBJECTID":718,"Id":0,"NAME":"LEONA DR"},"geometry":{"paths":[[[-13599252.3267,4548298.0004],[-13599251.8815,4548305.3243],[-13599250.6569,4548318.0003],[-13599248.9872,4548326.7325],[-13599246.6495,4548336.5917],[-13599244.2004,4548346.8733],[-13599241.1948,4548356.8733],[-13599238.1893,4548366.0282],[-13599234.8496,4548374.0563],[-13599230.9535,4548384.0563],[-13599224.0517,4548399.9717]],[[-13599214.4229,4547925.0618],[-13599204.5652,4547939.147],[-13599192.2142,4547964.9104],[-13599188.7633,4547972.6565],[-13599185.3124,4547980.4028],[-13599183.5313,4547985.0505],[-13599180.637,4547992.6559],[-13599178.4106,4547999.2752],[-13599175.5163,4548011.5284],[-13599174.737,4548015.4719],[-13599173.5126,4548021.6688],[-13599172.2881,4548028.57],[-13599171.6201,4548033.0768],[-13599170.9522,4548039.133],[-13599170.6182,4548046.0342],[-13599170.8409,4548052.6536],[-13599171.0634,4548059.1323],[-13599171.2861,4548066.7377],[-13599171.7314,4548075.1881],[-13599172.3993,4548082.7935],[-13599173.7352,4548089.8357],[-13599175.071,4548094.9058],[-13599178.2992,4548107.4407],[-13599180.0804,4548113.2152],[-13599182.752,4548120.6798],[-13599185.9803,4548128.9895],[-13599188.0954,4548133.778],[-13599190.3217,4548138.144],[-13599193.3274,4548143.7777],[-13599209.1348,4548169.9743],[-13599229.5063,4548203.7765],[-13599233.8476,4548211.5227],[-13599238.6344,4548221.6635],[-13599241.0835,4548228.0014],[-13599243.0873,4548234.621],[-13599244.757,4548240.8182],[-13599246.5381,4548247.156],[-13599248.3192,4548254.7616],[-13599250.1004,4548263.2122],[-13599251.7701,4548277.2964],[-13599252.438,4548286.5922],[-13599252.4381,4548294.761]]]}}]}

It has two elements in the paths array for the feature. If we use the following command:

ogr2ogr -f GeoJSON test.json input_data.json OGRGeoJSON -nlt PROMOTE_TO_MULTI

we're going to have a GeoJSON but with the multiple paths squashed into one Multiline:

There was a fix for multilinestrings in ​https://trac.osgeo.org/gdal/changeset/34773.

I made a test with 2.2.0-dev and the issue seems to be fixed. My result is

Coordinates differ because of "ERROR 6: EPSG PCS/GCS code 102100 not found in EPSG support files. Is this a valid EPSG coordinate system?" but that is a different thing.

In 37099:

GeoJSON: support multilinestring from esriGeometryPolyline (fixes #6773)

[Even Rouault]

I've just backported r34773 to 2.1 in r37099

[ethervoid]

I've tested with the 2.1 branch and works.

Thank you very much for your quick response :)
