Google Panorama Montage

Download high resolution Google Streetview panorama images and stitch them together into a large panorama image

Version

1.2.1

Installation

npm install gpan

Dependencies

This application depends on imagemagick and uses the montage binary to create a large image from the separate image files downloaded via google api

Disclaimer

This application makes use of an onducumented Google Maps API. While you may access them, there is no guarantee that this API will not change in the future revisions to Google Maps.

Changes

  • Changes in 1.2.1
    • fixed an issue where the montage would try to build the montage before all tiles were downloaded
  • Changes in 1.2.0
    • init() and set() have merged into a single method .config()
    • savePanorama() now accepts a single pano_id or an array of pano_id's
    • gpan will now handle temporary files internally
    • gpan now depends on the node-temp library
  • Fixes in 1.2.0
    • google cbk(x) api call are made to random numbers (0-4) to spread load
    • errors on google cbk calls will bubble up.

Example usage

var gp = require("gpan")

//all settings are optional and default to the shown values
gp.config({ zoom_level:0                //panorama zoom level, default 0
        , tiles_prefix:'image_'            //tile image prefix, useful for montage
        , path_to_image:'panos'            //panorama will create this folder and store the panorama in it
        , output_prefix:'output_'        //prefix for the panorama image
        , tmp_dir_prefix: 'gpan_tmp'    //temp folder prefix
        , pub: true                        // path_to_image relative to app root or public folder
        })

//each setting can be changed separately
gp.config('zoom_level', 3);

//each setting value can be returned
var zoom = gp.config('zoom_level') // returns 3

//retrieve panorama image for Times Square, New York
gp.savePanorama('3q57BxQpP8dNzwD0R5PIzg', function(err,path){
    if(err)
        return handleError(err);
    console.log(path); //will return the full path to the panorama image
});
