[postgis-devel] Wrong output in AsTopoJson example

[Tom van Tilburg]

Thank you all for bringing a new version. I'm happy to see all the 
improvements.

In the smallprint there was some feature I got very excited about called 
"topology.AsTopoJSON".
But the manual gives a brief example which I feel is not correct.
Could it be that for topojson so called 'delta' values are needed in the 
coordinates instead of pure coordinates?
Also the order of the arcs in multipolygon seems wrong (why negative 
values?) and komma's are missing after each new arc.

IMO the example should be something like:

{ "type": "Topology", "transform": { "scale": [1,1], "translate": [0,0] 
}, "objects": {
"P3P4": { "type": "MultiPolygon", "arcs": [[[0]],[[1,2,3,4,5,6]]]}
}, "arcs": [
[[25,30],[6,0],[0,10],[-14,0],[0,-10],[14,0]],
[[35,14],[0,-8]],
[[35,6],[12,0]],
[[47,6],[0,8]],
[[47,14],[0,8]],
[[47,22],[-12,0]],
[[35,22],[0,-8]]
]}

Cheers,
Tom
