AARI VIII Meeting of the International Ice Charting Working Group October 22-26, 2007 Frascati, Italy Advances in presentation of satellite information within ENC Yury Shcherbakov AARI, St. Petersburg, Russia
2
AARI Preconditions of use the ENC /ECDIS for ice navigationsupport Preconditions of use the ENC /ECDIS for ice navigation support According to the last edition of SOLAS the use of ECDIS by vessels becomes obligatory ECDIS provides an opportunity of use of the hydrometeorological information as additional information (transparent) layers of an electronic chart It is easier for navigators to have all kind of information in one place (ECDIS) so that other inputs (Fax, pictures, telex, etc.) become not necessary
3
The System of Ice Navigation Support AARI
4
Communication Means
5
SATTELITE RECEIVING STATION (SCANEX) & ECDIS TERMINAL (m / v “Academic Fedorov” ) AARI
6
The View of ECDIS “Skipper” (LTD, Morintech) ААНИИ
7
Formats of the geo-referenced satellite images used in ECDIS “Skipper” AARI Projection definition as WKT string: PROJCS["unnamed", GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS84",6378137,298.257223563]], PRIMEM["Greenwich",0], UNIT["degree",0.0174532925199433]], PROJECTION["Polar_Stereographic"], PARAMETER["latitude_of_origin",90.000000], PARAMETER["central_meridian",110.000000], PARAMETER["scale_factor",1.000000], PARAMETER["false_easting",0], PARAMETER["false_northing",0], UNIT["Meter",1]] JPG-file PRJ-file
8
The choice of a ship route with use of the satellite image (Kara Sea, 2006, MODIS/TERRA). AARI Polynija Compacted ice
9
The choice of a ship route with use of the satellite image (Kara Sea, 23.03.2006, MODIS(TERRA) ). AARI Compacted ice Polyniya
10
Practical use of satellite images for ice navigation (21 March 2006, Gulf of Finland, MODIS(TERRA) ) AARI Open Water Actual Route Standard route
11
Practical use of satellite images ( NOAA AVHRR) for ice navigation (I / b “Sovetskii Soyuz”, 2003 July,Kara Sea) AARI 1.Mercator projection 2.Jpg- format(True color)
12
MODIS (TERRA ) IMAGE and ENC( dKart-Explorer) AARI Ship location Young ice THIN ICE
13
The accuracy of RADARSAT images geo-location estimated in the ECDIS environment AARI
14
Actual and recommended routes AARI Actual route Recommended route
15
Definition of accuracy of a geographical binding on control points with use of a ship radar (voyage of R/V “ Academic Fedorov” to the Antarctica) On a picture: 1 Control points (1 and 2 ) 2 Blue line – ship route AARI The accuracy of geo- referenced HRPT NOAA image is no worse than 0.5 Nautical miles. Ship location
16
The Ice navigation support at the high latitudes What's new? Support ice navigation in high latitudes Universal polar Stereographic projection North Pole && ECDIS AARI
17
The Ice navigation support at the high latitudes (continue) What’s new? Support ice navigation in high latitudes Universal polar Stereographic projection North Pole !! AARI
18
A question for IICWG Team AARI Would the IICWG Team like to include as a standard format for geo-referenced images prj - files with WKT – string ? (Ice code catalogue)
