mb0 / wkt Goto Github PK

While writing navitia-types I discovered that given abnormal inputs, one of these three functions (and possibly more, I haven't thoroughly checked) panics, unwinding into a panic of wkt.Parse.

Example inputs

• MULTIPOLYGON(((-11.33535 51.29165,0,0,-11.33535 51.29165))
• MULTIPOLYGON((
• MULTIPOLYGON(((-11.33535 51.29165,0,0,-11.33535 51.29165)
• MULTIPOLYGON(
• POLYGON(
• MULTIPOLYGON(((0

Hello...
First.. thanks for this.. a WKT library is exactly what I need. However, I am having a hard time seeing what to do at a point. I have WKT string:

MULTIPOINT(2.9283 67.225,2.9283 67.225,2.93 67.22,2.93 67.22,2.93 67.22,1.0333 67.715,4.5767 66.6783,4.5767 66.6783)

using geom, err := wkt.Parse([]byte(track)) where track is the above WKT string.
I can parse it and then a log.Printf("GEOM: %v \n\n", geom)
gives me

2016/02/18 14:35:08 GEOM: &{[{2.9283 67.225 0 0} {2.9283 67.225 0 0} {2.93 67.22 0 0} {2.93 67.22 0 0} {2.93 67.22 0 0} {1.0333 67.715 0 0} {4.5767 66.6783 0 0} {4.5767 66.6783 0 0}] 0}

Is this some way I can walk through these items so I can pull out the lat/longs and put them into a geojson file I am building with some other code? I can't range on the type wkt.Geom object given it's a struct. I am not even sure how the log is printing out the above points to be honest.

any help would be much appreciated...

Thanks!
Doug
