Recent volcano camera images

GeoNet's volcano camera images are an important part of the surveillance programme as any changes to a volcano can be observed and compared over time. Our cameras produce images periodically, with the frequency of image capture varying from camera to camera depending on the communications bandwidth to the site. During a volcanic event we may change the frequency of capture.

Static Image URLs

The following URLs provide links to thumbnail and full-size volcano camera images. These images are updated every time a new photograph arrives, typically every 15 - 30 minutes. When using these images beware of client-side caching to ensure that the latest image is displayed:

JSON files

The following URLs provide JSON files that contain information about the last one hundred volcano camera images. The JSON files update every time a new photograph arrives from a remote camera. This is typically every 15 - 30 minutes.

The JSON files contain the following elements:

{"images":[["one", "G20090706.234503.NZST.jpg", "tG20090706.234503.NZST.jpg", "11:45 pm (NZST) 6 Jul 2009"],
["two", "G20090706.231502.NZST.jpg", "tG20090706.231502.NZST.jpg", "11:15 pm (NZST) 6 Jul 2009"],
["three", "G20090706.224503.NZST.jpg", "tG20090706.224503.NZST.jpg", "10:45 pm (NZST) 6 Jul 2009"],
....etc...
]],
"dir":"/images/volcano/volcams/raoul",
"title":"Volcano Camera - Raoul, New Zealand",
"type": "FeatureCollection",
"features": [
{ "type": "Feature",
"geometry": {"type": "Point", "coordinates": [-29.254, -177.914]},
   "properties": null
}],
"crs": {
"type": "EPSG",
    "properties": {
    "code": "27200"
  }
 }
}

Each numbered element contains the name of a full size and thumbnail sized jpeg image as well as an image capture time string. The image name can be combined with the 'dir' element and the source server to build a full URL, e.g.:

http://www.geonet.org.nz/images/volcano/volcams/raoul/tG20091002.084502.NZDT.jpg

After an image is no longer referenced in the JSON file there is no guarantee that it will remain available on the server.

GeoJSON

GeoJSON are some additional objects that can be included/appended to an existing JSON document and geospatially enable the object(s) represented by, or included in, that JSON file. The example below only uses simple point data for a latitude/longitude pair, but more extensive polygons and other shapes are also able to be represented. See the GeoJSON specification for more information.

Note that the "crs" object is optional (CRS: Coordinate Reference System), but if left out GeoJSON assumes WGS84. The example above uses NZGD49. The following links have further information on datums in GeoJSON:

Movies

These URLs link to full size and small volcano camera movies and are produced in the Shockwave Flash format only. They are regenerated every hour from the latest 100 volcano camera images.
