West Coast Canadian National Marine Seismic Data Repository This release makes available the West Canadian Coast part of the results of an ongoing effort to scan and convert all our inventory of analog marine survey field records (seismic, sidescan and sounder) to digital format. These records have been scanned at 300 dpi and were converted into JPEG2000 format. Typically each of these files were from 1 to 2 gbyte in size before compression, and were compressed by a factor of 10:1. Empirical tests with a number of data sets suggest that there is minimal visual distortion of the scanned data at this level of compression. In this KML file, scanned data are available in a reduced-scale thumbnail format and a compressed full-resolultion JPEG2000 format. 2017-01-01 2017-12-12 Natural Resources Canada bob.courtney@Canada.ca Form DescriptorsNature and EnvironmentScience and TechnologyCanadaSeismicMarineSidescan SonarHigh resolutionSub-bottom sounderEarth sciencesGeologyGeophysicsGeographic information systems KMZ for Scanned Seismic HoldingsKMZ http://ftp.maps.canada.ca/pub/nrcan_rncan/raster/marine_geoscience/Seismic_Reflection_Scanned/WestCoastScannedSeismicCollection.kmz Collection of Integrated Marine Geospatial DataKMZ http://ftp.maps.canada.ca/pub/nrcan_rncan/raster/marine_geoscience/Seismic_Reflection_Scanned/NRCan%20Marine%20Data%20Holdings.kmz Master List of Scanned Seismic SectionsXLS http://ftp.maps.canada.ca/pub/nrcan_rncan/raster/marine_geoscience/Seismic_Reflection_Scanned/MasterScannedSectionList.xls
