底圖散點圖不能正確繪製

Question

基本上我有一個csv，裏面充滿了緯度和經度數據，我將其添加到數據框中的兩個單獨列中。然後用它來創建一個包含所有數據的地球儀。除了數據沒有正確繪製，我不知道爲什麼。

讀入數據文件並將其添加到csv。

data_col = ['IP', 'Reliability', 'Risk', 'Type', 'Country', 'Locale', 'Co-Ords', '?'] 
data = pd.read_csv('reputation.data', sep='#', names=data_col) 

以聯合ORDS列，並將其分割到兩個不同的列

data['Co-Ords'] = data['Co-Ords'].str.replace('ut: ','') 
data['lat'] = data['Co-Ords'].apply(lambda x: x.split(',')[0]) 
data['lon'] = data['Co-Ords'].apply(lambda x: x.split(',')[1]) 

實施數據底圖;

m1 = Basemap(projection='ortho', lon_0=4,lat_0=46, resolution='l') 

fig=plt.figure(figsize=(12, 6)) 

m1.drawmapboundary(fill_color='black') 
m1.fillcontinents(color='white',lake_color='black') 
m1.drawcoastlines() 
m1.drawcountries() 

x=(data['lat']).as_matrix() 
y=(data['lon']).as_matrix() 

m1.scatter(x,y,cmap=cm.cool,marker="*", color='r', alpha=0.7, 
latlon=True, zorder=10) 
plt.title("IP Addresses on the Globe") 
plt.show() 

它看起來像如下： Globe

欣賞的幫助。

Answer 1

您通過x, y = m1(x, y)到convert your longitude and latitude to map coordinates需要讀取數據。在下面的代碼，我取代了線，你的矩陣變換與這一行，我想這是更清晰：

此代碼爲我工作

m1 = Basemap(projection='ortho', lon_0=4,lat_0=46, resolution='l') 
fig=plt.figure(figsize=(12, 6)) 

m1.drawmapboundary(fill_color='black') 
m1.fillcontinents(color='white',lake_color='black') 
m1.drawcoastlines() 
m1.drawcountries() 

x,y = m1(data['lon'].values, data['lat'].values) 
m1.scatter(x,y, marker="*", color='r', alpha=0.7, zorder=10) 

plt.title("IP Addresses on the Globe") 
plt.show()
