7 | ## Usage
|
8 |
|
9 | A minified bundle of this library is available on [npmcdn](https://npmcdn.com/covutils/).
|
10 |
|
11 | Usage is simple:
|
12 | ```html
|
13 | <script src="https://npmcdn.com/covutils@0.6/covutils.min.js"></script>
|
14 | <script>
|
15 | var coverage = ... ;
|
16 |
|
17 | // let's mask the Coverage with a GeoJSON polygon
|
18 | // any data values outside the polygon become null
|
19 | var polygon = {
|
20 | "type": "Polygon",
|
21 | "coordinates": [
|
22 | [ [100.0, 0.0], [101.0, 0.0], [101.0, 1.0], [100.0, 1.0], [100.0, 0.0] ]
|
23 | ]
|
24 | }
|
25 | CovUtils.maskByPolygon(coverage, polygon, ['x','y'])
|
26 | .then(function (maskedCov) {
|
27 | // work with masked Coverage
|
28 | })
|
29 | </script>
|
30 | ```
|
31 |
|
32 | If polygon-related functionality is not needed, then a lite bundle can be used instead:
|
33 | ```html
|
34 | <script src="https://npmcdn.com/covutils@0.6/covutils-lite.min.js"></script>
|
35 | ```
|
36 |
|
37 | ### CommonJS/JSPM/ES6
|
38 |
|
39 | You may also use this library within common package managers as it is published on npm.
|
40 |
|
41 | An ES6 import may look like that:
|
42 |
|
43 | ```js
|
44 | import {maskByPolygon} from 'covutils'
|
45 | ```
|
