JAXA/ALOS satellite Imagery

By NIED(National Research Institute for Earth Science and Disaster Prevention, Japanese national institute for disaster), a satellite image of Chile after the earthquake from JAXA(Japan Aerospace Exploration Agency) is permitted to be traced.

Note that the resolution is nearly as bad as the landsat imagery, so you cannot identify actual buildings. But it is possible to identify landuse and guess/interpret larger highways. (see discussion for an example of resolution)

International Charter Imagery

Activation of the International Charter Space and Major Disasters has been requested (WFP, UNOOSA) to support the damage assessment and response efforts in the earthquake that impacted Concepción, Chile on 2010-02-27. Clarification on re-usability of Charter imagery within the OSM project has been requested. Target area requested from the Charter are the following

  1. Concepción - Lat 36° 44’ 37” S; Long 73° 06‘ 33” W
  2. nearby Coronel - Lat 36° 58’ 39” S; Long 73° 10‘ 23” W

Information about what is being made available on http://www.un-spider.org/chile ( detailed page)

GeoEye and DigitalGlobe

Chris Nicolas from UNOSAT...

I am working now to put the recent GeoEye images of San Javier, Santiago, and Puerto Saavedra online as OGC WMS services, KML, and accessible within the OpenStreetMap. Attached are the shapefile coverages. These can be downloaded (~8Gigs) at

There is a WMS set up at http://geohub.jrc.ec.europa.eu/mapserv/chile?LAYERS=chile:geoeye

Coverage areas for way Puerto Saavedra and way San Javier. The images for the San Javier area appear to be off by about 10 meters, so first find some roads verified by GPS tracks to rectify your image background. There is also coverage around Santiago, but those images appear to be off by about 400 meters!

(Santiago images can also be adjusted to streets. Take large feature, like e.g. Club Hipico in the center, as starting landmark.)

More services here:

GeoEye and DigitalGlobe earliest imagery expected to be made available Sunday 28-Feb as well as clarification on its re-usability within the OSM project.

RapidEye

Coverage by RapidEye. See relation 421648

German company RapidEye AG published a 5000x5000 pixel JPEG of Concepcion and its surrounding area. They announced to publish future images and a reference from before the earth quake soon. See their website and press release for more information.

The resolution seems to be 6.5m (high enough to see larger roads, but too low to actually see any damages). And, sadly, the image suffers from heavy JPEG compression artifacts. Apparently, this is the tile 1822122 which is (along with other tiles) available from the geodata kiosk in diverse formats (GeoTIFF, etc.) at the same resolution, priced about 186 Euro (approx. 250 US-Dollar. Maybe there is a way to get it for free, but following the usual checkout process, that amount would be billed.)

Use the tag: source=RAPIDEYE/RE3/LEO, 2009-02-27

Rapideye has now (2010-03-03) released images from after the earthquake explicitly allowing use in OSM. They are available on a WMS for use in JOSM and as tiles for Potlatch.

Eros-B

Russian Company ScanEx published tiles of Constitución and its surrounding area.

The resolution seems to be 0.7m (from the EROS-B specs).

ScanEx has now (2010-03-04) released images from after the earthquake. They are available on a WMS for use in JOSM and as tiles for Potlatch.

The image can also be seen in this viewer.

Yahoo! imagery

Available pre-quake imagery

As of February 2010, the only high resolution image data available is the normal Yahoo! Aerial Imagery. This only covers Santiago (coverage map) and Iquique, and is pre quake (around 10 years old and might not reflect the current reality!)

Low resolution Landsat imagery is available for the entire impacted area, as well as low resolution Yahoo! Aerial Imagery.

Existing Data Sets

Attribution of data used in OSM is very important. In the table below, 'source' and 'source_ref' columns correspond to source=* and source_ref=* values, while 'resource/info' is freeform and section-linked. At present, only things which have been used are represented.

USGS Earthquake Hazards Program

As stated on the website, "This web site is provided by the United States Geological Survey’s (USGS) Earthquake Hazards Program as part of our effort to reduce earthquake hazard in the United States." However, the resource provides global information as well.

Information such as location, time and magnitude for the primary and aftershock events for this earthquake can be found on the Earthquake List for Map of S America Region. Several records have been interrogated from this resource to create natural=epicentre objects. A list of these objects in the vicinity of the primary epicentre is automatically generated by the Query-to-map resource; the list is accessible from http://toolserver.org/~kolossos/qtm2/featurelist.php?key=natural&value=epicentre&types=points-areas-infos&BBOX=-73.7051612,-38.1451672,-70.3863533,-33.2718196 . Aftershocks >6 in magnitude have been collected into relation 418723, a static rendering of which appears on the main 2010 Chile earthquake page.

The "index to available products" is a boundary listing of the resources available. This is provided as a .kmz file. The .kmz file can be converted to a .gpx file using the online tool KML2x provided by Zonum Solutions. This .gpx file can subsequently be opened in JOSM.
