issue with converting points

[stephanietuerk]

I'm trying to use topojson.py to convert a geojson to topojson. The geojson was made with geopandas — originally the points were shapely point objects. My geojson looks like this:

"type": "Feature", "properties": { }, "geometry": { "type": "Point", 
"coordinates": [ 62.269649605592754, 32.429278041035452 ] } }

and I get the following error when trying to convert:

~/anaconda3/lib/python3.6/site-packages/topojson/mytypes.py in 
Point(self, point)
     35             self.polygon(coordinate);
     36     def Point(self,point):
---> 37         self.point(point['coordinates'])
     38     def Polygon(self,polygon):
     39         self.polygon(polygon['coordinates'])
TypeError: point() takes 1 positional argument but 2 were given

I'm calling topojson like so:

topojson("points.json", "pointstopo.json", quantization=1e6, simplify=0.0001) 

I can't understand what I'm doing wrong, so I'm wondering if this is a bug/if there is some sort of larger incompatibility going on.

(Also, thanks for your work developing this package!)

Also you need to change your input data, into something like this:
{ "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": { }, "geometry": { "type": "Point", "coordinates": [ 62.269649605592754, 32.429278041035452 ] } } ] }

Thanks for following up on this. I see that you opened a new issue to deal with this. Just wanted to quickly confirm that this still occurs with properly formatted jsons generated from geopandas.

Input data:

{
"type": "FeatureCollection",
"crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:OGC:1.3:CRS84" } },
"features": [
{ "type": "Feature", "properties": { "geo_precision": 1, "count": 5 }, "geometry": { "type": "Point", "coordinates": [ -17.4646, 14.7574 ] } },
{ "type": "Feature", "properties": { "geo_precision": 1, "count": 5 }, "geometry": { "type": "Point", "coordinates": [ -17.4633, 14.6875 ] } },

Gets the same error.

~/anaconda3/lib/python3.6/site-packages/topojson/mytypes.py in Point(self, point)
     35             self.polygon(coordinate);
     36     def Point(self,point):
---> 37         self.point(point['coordinates'])
     38     def Polygon(self,polygon):
     39         self.polygon(polygon['coordinates'])

TypeError: point() takes 1 positional argument but 2 were given

Using the PR #31, seem to work properly, in your data also seems that a ']' is missing, I use your data and seems to work properly here is the output:

{"type": "Topology", "bbox": [-17.4646, 14.6875, -17.4633, 14.7574], "transform": {"scale": [1.300001300001823e-09, 6.990006990007041e-08], "translate": [-17.4646, 14.6875]}, "objects": {"name": {"type": "GeometryCollection", "crs": {"type": "name", "properties": {"name": "urn:ogc:def:crs:OGC:1.3:CRS84"}}, "geometries": [{"type": "Point", "coordinates": [0, 999999], "properties": {"geo_precision": 1, "count": 5}}, {"type": "Point", "coordinates": [999999, 0], "properties": {"geo_precision": 1, "count": 5}}]}}, "arcs": []}
