The library is integrated to following places

- Clone this repository to your local environment.
- Run
npm install
to install all the necessary packages required. - Open
examples/index.html
in your browser to look at the preview of the library.
- Install grunt - https://gruntjs.com/installing-grunt.
- Make the changes you are working on in respective /src files.
- Run
grunt build
to generate files in the /dist directory. - Run
grunt jasmine
to run tests on the LEL layers and ensure they pass. - Test your changes on a browser by opening
examples/index.html
.
Checkout this demo : https://publiclab.github.io/leaflet-environmental-layers/example/index.html#3/43.00/-46.23
Click and drag the map to pan it.
Use the button on right-most corner to change the way the background of the map looks .
Toggle certain layers on and off using the Layers button in the toolbar .
Click on a point or marker on the map to learn more about it .
In src/legendCreation.js
, add addLayerNameURLPair(layer_var, "img_url");
, where layer_var
is consistent with the variable used in example/index.html
and img_url
is the source of the image to be used as the legend.
We can source locations from a spreadsheet in a format like this:
Title | Latitude | Longitude | Notes |
---|---|---|---|
First | 29.671282 | -95.17829 | The first marker |
Second | 29.760371 | -95.504828 | The second marker |
Third | 29.917755 | -95.283494 | The third marker |
The layer is constructed like this:
var layer = L.SpreadsheetLayer({
url: 'https://docs.google.com/spreadsheets/d/14BvU3mEqvI8moLp0vANc7jeEvb0mnmYvH4I0GkwVsiU/edit?usp=sharing', // String url of data sheet
lat: 'Latitude', // name of latitude column
lon: 'Longitude', // name of longitude column
columns: ['Title', 'Notes'], // Array of column names to be used
generatePopup: function() {
// function used to create content of popups
},
// imageOptions: // optional, defaults to blank
// sheetNum: // optional, defaults to 0 (first sheet)
});
layer.addTo(map);

1.) Add link :
<script src="../node_modules/leaflet-fullhash/leaflet-fullHash.js"></script>
2.) Once you have initialized the map (an instance of L.Map), add the following code :
// Assuming your map instance is in a variable called map
var hash = new L.Hash(map);
