Constructors¶
GeoDataFrameColumn.fromGeoJsonGeometry
¶
Build a column from parsed geojson objects
Positional parameters:
geometry: | dynamic : a geojson geometry: either a GeoJsonPoint
, a GeoJsonMultiPoint
or a GeoJsonLine |
---|---|
columnName: | String : the name of the column |
final col = GeoDataFrameColumn.fromGeoJsonGeometry(someGeoJsonObject, "myline");
print(col.dtype);
print(col.type);
GeoDataFrameColumn.inferFromDataPoint
¶
Build a column with types infered from a datapoint
Positional parameters:
dataPoint: | dynamic : a sample of the data to check to infer types |
---|---|
columnName: | String : the name of the column |
