python代碼生成器，python自動生成坐標腳本_用一個簡單的python腳本從經緯度坐標獲得高程

我從這個question得到了一個python腳本，它將從USGS高程點查詢服務中提取。但是，它總是超時，并在一段看似隨機的時間之后，在查詢完成之前將我踢出。我需要另一種方法來獲取給定緯度坐標的高程數據。在

以下是我當前的查詢：# ========= pull elev from usgs server ======

python代碼生成器？# USGS POINT QUERY SERVICE ==================

url = r'https://nationalmap.gov/epqs/pqs.php?'

# ===========================================

python根據坐標點畫線。# coordinates with known elevation

lat = [48.633, 48.733, 45.1947, 45.1962]

lon = [-93.9667, -94.6167, -93.3257, -93.2755]

python自動生成表格、# create df

df = pd.DataFrame({

'lat': lat,

python坐標圖？'lon': lon

})

def elevation_function(df, lat_column, long_column):

python獲取文字坐標，elevations = []

counter = 0

start = time.time()

for lat, lon in zip(df[lat_column], df[long_column]):

# define rest query params

params = {

'output': 'json',

'x': lon,

'y': lat,

'units': 'Meters'

}

# format query string and return query value

result = requests.get((url + urllib.parse.urlencode(params)))

elevations.append(result.json()['USGS_Elevation_Point_Query_Service']['Elevation_Query']['Elevation'])

counter += 1

print('Proportion of job complete: {}'.format(round(counter/df.shape[0],3)))

end = time.time()

print(str(round(end - start)) + " seconds into job\n")

df['elev'] = elevations

return elevations

start = time.time()

count = 0

for i in range(100):

count += 1

elevations = elevation_function(df, lat_column='lat', long_column='lon')

end = time.time()

print(str(round(end - start)))
