Dataset description: Hars2000Pseudo

GeoTIFF image of the shaded-relief bathymetry of the sea floor, colored by backscatter intensity, of the Historic Area Remediation Site in 2000 (3-m resolution, Mercator, WGS 84)

Comments:
This is Edition 2.0 of GeoTIFF Hars2000Pseudo.tif. An error in the University of New Brunswick (Clarke, 1998, see cross reference) processing software that resulted in the multibeam observations not being properly projected onto a plane was discovered in 2003. A second error in the gridding algorithm was discovered in 2007, requiring a shift of 1/2 grid cell to northwest. Edition 2.0 differs from Edition 1.0 (Butman and others, 2002) in that it was processed using corrected software; comparison of the location of selected features suggests that Edition 2.0 is shifted approximately 10 m to the east compared to Edition 1.0.
