I'm having problems reading an OpenStreetMap buildings (IMPOSM GEOJSON) file into a geopandas data frame object (Python 2.7). This is on MAC OS X 10.11.3. Here are the messages I'm getting:
>>> import geopandas as gpd
>>> df=gpd.read_file('san-francisco-bay_california_buildings.geojson')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/ewang/anaconda/lib/python2.7/site-packages/geopandas/io/file.py", line 28, in read_file
gdf = GeoDataFrame.from_features(f, crs=crs)

return Polygon(ob["coordinates"][0], ob["coordinates"][1:])

n = len(ob[0])
IndexError: list index out of range
The odd thing is that I can load OSM roads data IMPOSM GEOJSON files with geopandas. Am I missing something obvious here? Thanks very much.
