PeakFinder-API

This page contains information about embedding the PeakFinder mountain panorama module to your website.

PeakFinder supports 3 different methods to embed the Panorama Panel to a website:

• Url-Format: Create a link including latitude/longitude and some optional parameters to link to the PeakFinder website
• Embed with iFrame: Add an iFrame container to your website with latitude/longitude
• Embed with Canvas: Use Javascript for full control of the Panorama Panel

Url-Format

PeakFinder provides a simple interface that allows you to create a link to a certain viewpoint or to embed PeakFinder directly on your homepage as an iFrame.

PeakFinder URL Format The following link opens the PeakFinder website with the given viewpoint: https://www.peakfinder.com/?lat=42.8612&lng=-72.109&name=Monadnock&ele=941

The following links opens the PeakFinder app with the given viewpoint on your iOS or Android device:

• peakfinder://?lat=42.8612&lng=-72.109
• peakfinder://?lat=42.8612&lng=-72.109&name=Monadnock
• peakfinder://?lat=42.8612&lng=-72.109&name=Monadnock&ele=941
• peakfinder://?lat=42.8612&lng=-72.109&name=Monadnock&ele=941&off=500

Arguments

Additionally to the required parameters lat and lng you can add the following arguments:

Key	Argument	Description

Embed with iFrame

With the following code you can embed PeakFinder directly to your homepage. Check out this example page: basicexample_iframe.html.

<iframe src="https://www.peakfinder.com/embed/?lat=42.8612&lng=-72.1092&name=Monadnock%20Mountain&ele=941&zoom=5&azi=255" 
    frameBorder="0" width="100%" height="570" name="peakfinder">
<p>Your Browser do not support iFrames.</p>
</iframe>

---

Embed with canvas

This method gives you the most flexibility. You can use Javascript to control the PeakFinder module.

Check out this example page: basicexample_canvas.html.

You must do the following steps:

• Include Javascript
• Create canvas tag
• Load script

Include Javascript

Include https://www.peakfinder.com/script/peakfinder.1.0.min.js in your html header:

<script async type="text/javascript" src="https://www.peakfinder.com/script/peakfinder.1.0.min.js"></script>

Create Canvas Tag

Add the following canvas tag your your html body:

<div class="content">
  <canvas id="pfcanvas" oncontextmenu="event.preventDefault()"> </canvas>

  <!-- you can also add an optional div that will be hidden when the PeakFinder modele has been loaded -->
  <div id="pfcanvasprogress">
    <div class="spinner" id="spinner">
    </div>
  </div>
</div>

Load script

Add the following script to load the module:

if (PeakFinder.utils.caniuse()) {

  let panel = new PeakFinder.PanoramaPanel({
    canvasid: 'pfcanvas', 
    locale: 'en' // attach to canvas
  }) 
  
  panel.init(function() {
    // inside here its save to use the panel
    
    panel.settings.distanceUnit(1) // use imperial (miles, feet) format
            
    panel.loadViewpoint(46.53722, 8.12610, 'Finsteraarhorn') // loads a viewpoint

    // animate to view
    panel.azimut(209.0, 2.0)
    panel.altitude(1.0, 1.0)
    panel.fieldofview(45.0, 2.0)
  });
}

Functions

PeakFinder~PeakFinder : object

Constructor: Initialization of the PeakFinder PanoramaPanel. Pass the options in a Javascript dictionary:

Properties

Name	Type	Description
canvasid	string	The id of the html canvas element. Default: 'canvas'
locale	string	The language locale of the module. Default: 'en'. Supported locales: en,de,fr,it,es,pt,ja,ko,zh-Hans,zh-Hant
bgcolor	string	A custom color for the background/sky. Normally the sky is white. For another color use the format '#rrggbb' (e.g. #87CEEB for sky color).

Example

let panel = new PeakFinder.PanoramaPanel({
  canvasid: 'pfcanvas', 
  locale: 'en'
}) // attach to canvas

PeakFinder~registerCommandsCallback(command)

Registers a callback that receives commands/messages from the PanoramaPanel. The PanoramaPanel will send a message when a specific event occured. E.g. when a new viewpoint was loaded the command:
viewpoint changed lat=46.53722&lng=8.12610
will be sent. Normally register to this callback can be skipped.

Param	Type	Description
command	function	function must have the format functioname(command).

Example

panel.registerCommandsCallback(function(cmd) {
  console.log(cmd)
})

PeakFinder~init(callback)

Loads all the needed stuff for displaying the panorama. Call this method only once. The async callback will inform when the panorama panel is ready. After this call additional commands like loadViewpoint may be called.

callback	function	This function will be called when everything is ready

Example

panel.init(function() {
  console.log('ready')
  // inside here you can use panel
  panel.loadViewpoint(46.53722, 8.12610, 'Finsteraarhorn')
  
});

PeakFinder~asyncinit()

Loads all the needed stuff for displaying the panorama. Call this method only once. Same as the init function but with support for the Javascript async pattern. After this call additional commands like loadViewpoint may be called.
