They have not yet installed a direct link for address search (only for communes) on Geoportail. So you must choose : Plus de service/pages jaunes/villes en direct/vues aérienne to find the address search engine... Hi, According to WIKIPEDIA, « Google Earth accuracy : Most land areas are covered in satellite imagery with a resolution of about 15 m per pixel [LandSat 7 ?], and some population centers are also covered in aircraft imagery (orthophotography) of several pixels per meter [until 0.125 m ?]. Oceans are covered in much lower resolution. » I've made again... a little (approximative) survey. SORRY !!! Here are only the best results found on the web in each category, by level of resolution + IGN and SPOT IMAGE since... France is here concerned..., but France is not the only european country to open this kind of free geographical website : AERIAL PHOTOS (orthophotography) : Others « free as well » (i.e. : zoom over large zones) : GEOCONTENT (DE) : 0.2 m (Berlin) ; 0.5 m (virtually all Germany) colour (but with green lines) ; 3 D : http://www.dlkviewer.de . AERODATA (BE) : 0.2 m colour (Antwerp-Brussels corridor) ; 3 D : http://www.aerogrid.be . USGS (US) through NASA WORLD WIND (future DIGITAL EARTH ?) : 0.25 m colour (main US cities, N.Z) and 1 m black & white ; 3 D. IGN (FR) : GEOPORTAIL : 0.5 m colour (all France and part of french oversea territories) ; 3 D in Octoberr 2006. « Paying » (i.e. : without zoom found) : SANBORN (US) : 0.03 m (client requiring) ; 0.15 or 0.30 m (main cities) colour ; 3 D. PHOTOGRAMMETRIE PERRINJACQUET (CH) 0.05 to 0.25 m colour (6 cantons + cities) ; 3 D. THE GEOINFORMATION GROUP & GETMAPPING (UK) : 0.0625 m ? (no ultra-precise black zone visible on the general map) ; 0.125 colour (63 % of UK + cities) ; 0.25 m colour (most of UK) ; 3 D. Etc... Governmental : Germany : http://www.bkg.bund.de New-Zeland : http://www.linz.govt.nz/core/topography/aerialandorthophotos/index.html Japan : www.gsi.go.jp/ENGLISH, etc... or not www.imageone.co.jp, etc... SATELLITE PHOTOS : http://www.npoc.nl/EN-version/satelliteinfo/satellitetabel.html Spy satellite : ANRO (American National Reconnaissance Office) : KH-13 satellite : resolution 0.04 m ? black & white (classified, but not in the NPOC tables !) So, Mixi watch hands (aiguilles) are at least 4 cm long... ANRO : KH-12 : 0.15 m black & white (classified, but not in the NPOC tables !). Etc... French one : HELIOS 2A : 0.5 m (classified). Public release (paying) : DIGITALGLOBE (US) :QUICKBIRD : 06 - 07 m black & white (panchromatic) ; 2.4 - 2.8 m colour (multispectral). ORBIMAGE (US) : ORBVIEW 3 : 1 m black & white ; 4 m colour. To be replaced in 2007 by ORBVIEW 5 : 0.41 m black & white ; 1.64 m colour, then the MOST ACCURATE. SPACE IMAGING (US) or ? SIC (Satellite Imaging Corporation) : IKONOS 2 : 1 m black & white ; 4 m colour. KARI (Korean Aerospace Research Institute) : KOMPSAT 2 : 1 m black & white ; 4 m colour ; « merged » 1 m ? (made by EADS, the camera by a german company, and normally launched TOMORROW !). NSPO (Taiwan National Space Organisation) FORMOSAT 2 : 2 m black & white ; 8 m colour (made by EADS). French one : SPOT IMAGE : SPOT 5 : 2.5 m black & white ; 10 m colour ;.« merged » 2.5 m ? « seems » possible, see last image in http://www.geoimage.com.au/geoweb/spot/spot_overview.htm or http://www.spot.com/html/SICORP/_401_402_403_404_.php To be replaced in 2008 by : PLEIADES : 0.7 m black & white ; 2.8 colour ; « merging » ? (= actual QUICKBIRD resolution) : http://smsc.cnes.fr/PLEIADES/index.htm (IGN will be a « user organisation » of PLEIADES images but I don't know if they will up-date GEOPORTAIL with them). NASA WORLD WIND (future DIGITAL EARTH ?) (US) : 15 m black & white ; 30 m colour (Landsat 7). TERRA METRICS (US) : 15 m colour ? or like previous one. BUT MANY... are to be launched this very year 2006 by : Italy : COSMO-SKYMED : 0.7 m black & white ; 2 m colour. Then the 2nd most accurate on the market : FORZA ITALIA ! (& Russia ?) Israel-US : EROS B1-5 : 0.7 m black & white ; 4 m colour. UK : DMC 2 : 2.5 m black & white ; 5 m colour. Japan : ALOS : 2.5 m black & white ; 10 m colour. Etc... So, on Google Earth, ; the most precise zones (urban areas notably) are apparently orthographic with a 0.125 to 0.25 m ? resolution (0.6 m with satellite ?). Paris was apparently up-dated with The Geoinformation Group 0.125 m resolution images, which are 4 times more precise than Geoportail with its 0.5 m/pixel resolution. In fact the difference seems higher (8 times ?) but it doesn't seem to look like 0.0625 m resolution images and I doubt that the KH-13 key hole satellite was used for this Paris area coverage... :+) So how can be explained this incoherence, or the difference of quality with the corresponding IGN paper photos ? The IGN could nevertheless later make some more accurate aerial orthophotos above the main french cities to complete Geoportail, or « perhaps » buy too, meanwhile, the Geoinformation Group images for Paris. The 3 D should be available this October, apparently for all France. The actual possibility to make a search by city name, to easily switch between image, coloured relief (rather funny) and topographic map is already quite usefull. I precise that a left clic on the image enlarges it while a right clic reduces it. But it's impossible to get a larger view than a 80 km side sq |
