-
- KOSMOS
-
- Russian imagery; currently the highest spatial resolution of any
- available. The KVR-1000 camera produces imagery at up to 2-meter
- resolution (panchromatic). There are online samples at
- http://cen.cenet.com/htmls/d2/sate.htm.
-
- A fine sample in the Eurimage 1995 calender shows KVR-1000 combined
- with Landsat TM to give the effect of ultra-high-resolution colour
- imagery. The TK-350 camera offers 10-meter resolution, and stereo
- capabilities.
-
- Technical information on the net is (AFAIK) sparse, but Ivan Krasnyj
- (ivan@krasnyj.spb.su at the time) posted the following:
-
- TK-350 (Topographic Camera) has high measuring
- characteristics. The images obtained by this camera have 10 m
- ground resolution, average scale is 1:660000, image size is
- 30x45 cm, one image covers the area 200x300 km, and longitudinal
- stereoscopic overlap is 60% or 80%.
- Stereoscopic overlap of TK-350 camera images (maximum value
- of B/H ratio is close to 1) provides the obtaining of ground
- relief mean error of 7 m, which is more better than for other
- existing systems.
- The image can be enlarged up to 1:50000 scale.
-
- KVR-1000.
- KVR-1000 (High Resolution Camera) can work together with
- TK-350 and provides the obtaining of the images with 2 m ground
- resolution, 1:220000 average scale, image size is 18x18 cm, and
- one image covers area 40x40 km. Camera works in panchromatic
- spectral range. The materials obtained by means of KVR-1000 let
- one to perform the detailed identification of the area of
- shooting. The images can be enlarged up to 1:10000 scale without
- significant loss of quality, which makes possible to create on
- their basis photomaps, photoplans and other products of scale
- 1:10000 and smaller.
-
- Joint use of photo materials made by TK-350 and KVR-1000
- cameras together with the numerical measuring parameters, which
- are registered at the moment of shooting, let one to perform
- photogrammetric processing and to create topographic and
- photomaps of 1:50000 scale and smaller. It is possible to
- create maps practically of any region of the Earth surface,
- including the territories, where geodetic reference network is
- unavailable.
-
- Images can be delivered in the form of film, paper print and
- as digital data.
-
- Landsat
-
- Landsat's mission is "to provide for repetitive acquisition of high
- resolution multispectral data of the earth's surface on a global
- basis". Landsat is the "classic" Earth Observation satellite, dating
- back to 1972. The MSS (Multispectral Scanner) instrument provides
- visible/infrared imagery at 80m resolution; the TM (Thematic Mapper),
- first deployed on Landsat 4 in 1982, improves this to 20-30m.
-
- Comprehensive guides are available at
- http://sun1.cr.usgs.gov/glis/hyper/guide/landsat.
-
- http://sun1.cr.usgs.gov/glis/hyper/guide/landsat_tm.
-
- World-map based WWW browsing of Landsat TM imagery is available from
- http:tracy.esrin.esa.it:8001/www/ or http://www.coresw.com.
-
- 1982-1985 TM, and 1972-1992 MSS data are available at reduced prices
- from USGS. See http://sun1.cr.usgs.gov/glis/hyper/news/tm.html. See
- also the Landsat Pathfinder, at

-
- Nimbus
-
- Description and imagery at http://gds.esrin.esa.it/CNIMBUS
-
- (AFAIK) most noted for the CZCS ocean colour and other marine maps.
- This data is available in a variety of net locations and on CDROM. See
- the SeaWiFS project's pages at
- http://seawifs.gsfc.nasa.gov/SEAWIFS/IMAGES/CZCS.html
-
- NOAA Polar Orbiting Environmental Satellites (POES)
-
- This long-running (1978-) series of satellites carry the AVHRR
- instrument. A passive visible/infrared instrument imaging a broad
- (2400Km) swath, this is the most widely used of any in large-area
- (including continental and global scale) Earth Observation.
-
- A very comprehensive collection listing sources for data, information,
- technical reference, and describing applications is actively
- maintained by FAQ co-author Wim Bakker at
- http://www.itc.nl/~bakker/noaa.html
-
- There is a comprehensive technical guide to AVHRR imagery at
- http://sun1.cr.usgs.gov/glis/hyper/guide/avhrr.

- RESURS
-
- Resurs imagery represents an important intermediate between the high
- spatial resolution of TM or SPOT and the high coverage of AVHRR or
- ATSR. A good writeup of this satellite available from SSC at

-
- Shuttle
-
- The principal Earth Observation missions (AFAIK) are Imaging Radar.
- There is also a collection of Earth Observation imagery at NASA/JSC
- http://images.jsc.nasa.gov/html/home.htm
-
- Shuttle Imaging Radar
-
- Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar
- The most recent Shuttle Imaging Radar mission is a joint venture of
- NASA and the German and Italian national space agencies. It is
- equipped with an advanced imaging radar operating at three different
- wavelengths, and a variable viewing angle. SIR-C missions took place
- in April and October 1994. It is well covered by several good
- webpages, including:
- * NASA JPL have an excellent imaging radar homepage at
- http://southport.jpl.nasa.gov/, the serious contents of which is
- at http://southport.jpl.nasa.gov/scienceapps.html. Links from this
- page include information and browse images, and also an
- interactive _bulletin board_ (nice)! for discussion of imaging
- radar.
- * DLR have a SIR-C/X-SAR page http://www.op.dlr.de/ne-hf/SRL.html,
- containing general and mission information and online imagery, and
- an excellent description.
- * USGS/EDC have a SIR-C/X-SAR page at
- http://sun1.cr.usgs.gov/landdaac/sir-c/sir-c.html, with general
- information and browse facility.
-
- There is also a new browser at
- http://ic-www.arc.nasa.gov/ic/projects/bayes-group/Atlas/Earth/.
- However, it refused to serve me images: someone tell me whether it's
- broken or whether I have a problem?
-
- Shuttle Handheld Photography
-
- Information and imagery is available from JSC at
- http://eol.jsc.nasa.gov/sseop.html.
-
- Satellite Pour L'Observation de la Terre (SPOT)
-
- The French SPOT satellites provide high-resolution visual/infrared
- Earth Observation imagery. At 10m (Panchromatic) / 20m
- (Multispectral), SPOT imagery offers higher resolution than the major
- alternative Landsat. In addition, SPOT is the leading provider of
- stereoscopic (3-dimensional) imagery.
-
- Spot is on the Web at two apparently identical sites:
- http://www.spotimage.fr and http://www.spot.com. There is a
- comprehensive technical guide to SPOT at
- http://sun1.cr.usgs.gov/glis/hyper/guide/spot.
-
- Browsing SPOT imagery can be challenging (but check out
- http://www.coresw.com/.
-
- For the time being, Spot Image's DALI catalogue system is no longer
- accessible through IDN, as previously reported here. It is available
- on WWW through SPOT's websites on payment of a fee, or by X29
- connection. As usual, Wim Bakker tracked down the currently valid
- information:
-
- To be complete:
-
- OLD X29 numbers:
- -(2080)31001232
- -(2080)310012323
- -(2080)3100123203
-
- NEW X29 numbers:
- -(2080)31081141
- -(2080)310811413
- -(2080)31081141303
-
- For me the following command on a VAX/VMS works for connecting to DALI:
-
- $set host/x29 02080310811413
-
- Username and password (as used by the CEOS-IDN "LINK") QLEMAST and MASTER
- still work!
-
- _(the IDN presumably *could* gateway to the new X29 numbers and thus
- reinstate the service as previously described)_
