OuterSpatial Map Library

Extends Leaflet to include functionality and a look-and-feel built specifically for OuterSpatial.

This library is under active development, so please help test and report issues.

OuterSpatial Map Builder

OuterSpatial Map Builder is a graphical interface that walks through the process of building a map with OuterSpatial Map Library, step-by-step. This project is currently private, but we're exploring ways to open source it.

Thanks

Initial development on this library was done by the U.S. National Park Service's NPMap team and called NPMap.js. The agency recently made the repository private, but luckily made the code available in the public domain so we (Trailhead Labs) have decided to host it and push development forward.

The original design was heavily inspired (cough cough) by Mapbox.js, and, of course, built on the great Leaflet library. Many thanks to the authors of all the great plugins used in/by the library (take a look at LICENSE.md for a list).

Versioning

OuterSpatial Map Library is versioned using semantic versioning. This means that releases are numbered: major.minor.patch and follow these guidelines:

• Breaking backward compatibility bumps the major (and resets the minor and patch to zero)
• New additions that don't break backward compatibility bumps the minor (and resets the patch to zero)
• Bug fixes and miscellaneous changes bumps the patch

2.0.0 was the first official OuterSpatial Map Library version.

Keys

OuterSpatial Map Library supports connecting to a number of services that require API keys. You will need to create a copy of keys.sample.json, rename it keys.json, add your keys, and run grunt build to bundle your keys into the build of OuterSpatial Map Library that is created in the _dist folder.

Building

You must have node.js and Yarn installed to run the build. After installing node.js:

git clone https://github.com/trailheadlabs/outerspatial-map-library
cd outerspatial-map-library
yarn install

Install the Grunt command line tool (do this once as an admin user after installing node.js):

yarn global add grunt-cli

Copy keys.sample.json to a file called keys.json, then modify keys.json, adding your own API keys:

cp keys.sample.json keys.json

Then use Grunt to build the library:

grunt build

Internally, the Grunt task uses browserify to combine dependencies. It's installed locally, along with other required packages, when you run npm install. The build task also uses uglify and cssmin to create minified versions of the library's CSS and JavaScript in dist/.

Deploying

This project contains sample code that demonstrates deploying OuterSpatial Map Library to "staging" and "production" Amazon S3 buckets using the grunt deploy-staging and grunt deploy-production commands, respectively. These commands will not work unless you make a copy of "s3.sample.json", rename it "s3.json", and update the information in it:

cp s3.sample.json s3.json

Testing

OuterSpatial Map Library uses the Mocha JavaScript test framework, with the expect.js assertion library, and PhantomJS to run the tests. You can run the tests with either of the following commands:

grunt test

OR

yarn test

We are working to expand test coverage for the library.

Documentation

Take a look at the API docs.

Examples

Simple and targeted examples reside in the examples directory. This is a great starting point if you're new to OuterSpatial Map Library.
