This library provides convenience functions for translating, geocoding, and calculating distances between geographical points. It is inspired by ruby's geokit and geokit-rails gems, and aims to make dealing with geographical data a little bit easier.

You can read the documentation here.

Import from github, and get geomancin'

import("github.com/kellydunn/golang-geo")

Currently, golang-geo provides the following functionality:

• Querying for points within a radius using your own SQL data tables.
• Transposing a point for a given distance and bearing.
• Calculating the Great Circle Distance bewteen two points.
• Geocoding an address using Google Maps API or Open Street Maps API.
• Reverse Geocoding a Point using the same services.

Keep in mind that you do not need to use SQL in order to perform simple Point operations and the only function that relies on SQL is PointsWithinRadius.

The project is configured to connect to a SQL database by reading a config/geo.yml file in the root level of your project. If it does not exist, it will use a Default SQL configuration that will use the postgres driver as described by lib/pq. The Default SQL configuration will attempt to connect as a user named "postgres" and with the password "postgres" to a database named "points".

If you want to supply a custom database conifguration, feel free to do so by using the template below:

development:
  driver: postgres
  openStr: user=username password=password dbname=points sslmode=disable
  table: points
  latCol: lat
  lngCol: lng

Or if you want to connect via MySQL, you can do that as well!

development:
  driver: mysql
  openStr: points/username/password
  table: points
  latCol: lat
  lngCol: lng  

Once you've supplied your configuration, you may connect to your database with the following line of code:

db, err := geo.HandleWithSQL()

• golang-geo currently only uses metric measurements to do calculations
• The $GO_ENV environment variable is used to determine which configuration group in config.yml is to be used. For example, if you wanted to use the PostgreSQL configuration listed above, you could specify GO_ENV=development which would read config.yml and use the configuration under the root-level key development.

• More Tests!
• Redis / NOSQL Mapper
• Bing Maps?
• Add an abstraction layer for PostgreSQL earthdistance / PostGIS

By default, golang-geo will attempt to run its test suite against a PostgreSQL database. However, you may run the tests with mocked SQL queries by specifying that you want to do so on the command line:

DB=mock go test

The $DB environment variable is used to specify which database you'd like to run the tests against. You may specify postgres, mysql, or mock. The Travis CI builds for this project currently runs against all of these when running the test suite.
