Usage Example

Basically, you only need to do three things, and geomate will take care of everything else for you:

1. Prepare your API keys.

2. Give the path of your database file.

3. Create a list of address or coordinate you want to geocode.

import geomate
import pprint

# put your google map API key here, what you see here is all fake
api_keys = [
    "GoogleGeoCodingApiKey01", # user1
    "GoogleGeoCodingApiKey02", # user2
    ...
    "GoogleGeoCodingApiKey99", # user991ihu8",
]

# create a google geocode API client
googlegeocoder = geomate.GoogleGeocoder(api_keys=api_keys)
googlegeocoder.check_usable() # show you which keys are available

# bind to a geocoder and database
batch = geomate.BatchGeocoder(googlegeocoder, db_file="geocode.sqlite3")

# construct your todo address list anyway you want
list_of_address = [
    "675 15th St NW Washington, DC 20005",
    "2317 Morgan Ln Dunn Loring, VA 22027",
    "1201 Rockville Pike Rockville, MD 20852",
    (39.085801, -77.084513),
    (38.872719, -77.306417),
    (38.902027, -77.053536),
]

batch.process_this(list_of_address) # process everything

# see what's we have done
for address in list_of_address:
    pprint.pprint(batch.lookup(address))

Advance Usage

Suppose you got 10000 address, but 5000 of them are invalid address, which is not able to geocoded. And invalid address happens to be at begin of the queue. You probably don’t want to waste API quota on that. geomate provide a keyword shuffle to randomlly perform the geocoding, so in average, you can get most of valid address geocoded in a short time:

batch.process_this(list_of_address, shuffle=True)

Here’s something may helpful. Basically there are two steps in the processing:

1. Insert to-do addresses as primary key into a table, and skip address already in database.

2. Do geocoding.

So you can take advantage of this for more flexible batch geocoding process.

batch.add_addresses(list_of_address)
batch.process_all(shuffle=True)

Lookup the geocoded data

You can easily retrieve the geocoded data by:

for address in list_of_address:
    data = batch.lookup(address)
    pprint(data)

Of course you can also manually read it from sqlite database.
