Change latlong to UTM coordinates. Error:must be real number, not str.

Question

我在将 csv 数据从 Latlong（度）更改为 UTM 坐标时遇到问题。 这是示例数据：

Date        Time    Latitude  Longitude
23/08/2018  9:00:00 -5.1661   119.4543
23/08/2018  9:00:01 -5.166    119.4544
23/08/2018  9:00:02 -5.1659   119.4544
23/08/2018  9:00:07 -5.1657   119.4546
23/08/2018  9:00:42 -5.162    119.4567
23/08/2018  9:00:43 -5.1614   119.4567
23/08/2018  9:00:44 -5.16     119.4548

我试过这种方法来改变坐标

df = pd.read_csv("data.csv")
s = gpd.GeoSeries([Point(x,y) for x, y in zip(df['Longitude'], df['Latitude'])])
geo_df = gpd.GeoDataFrame(df[['Date','Time']], geometry=s) 
geo_df.crs = {'init': 'epsg:4326'} 
geo_df = geo_df.to_crs({'init': 'epsg:32750'})
geo_df

但是我得到了TypeError: must be real number, not str

有解决问题的想法吗？

Answer 1

也许这有帮助

geometry = [Point(xy) for xy in zip(df.Latitude, df.Longitude)]
df = df.drop(['Latitude', 'Longitude'], axis=1)
crs = {'init': 'epsg:4326'}
gdf = gpd.GeoDataFrame(df, crs=crs, geometry=geometry)
gdf = gdf.to_crs({'init': 'epsg:32750'})
