Inshore Image collection standards Purpose  Based of the growth in use of images, suggest ‘Standard Practices’ for discussion.  Adopt and recommend these standards nationally as part of the coordination in the development of the Natural Image Analysis Laboratory

Coincidental Projects  Natural Image Analysis Lab – Image Archive  Large Vessel –Discovery Corridor –Fish Habitat –Fisheries (Clams, Sea Cucumber) –Deep Sea Corals  Inshore Vessels –Aquaculture interactions (research, regulatory) –Fisheries (Salmon, Lobster, Clams, Shrimp, Cukes) –Sea Dumping –Sea Grass Survey –Pockmarks

Coordinated processing

Image Management Plan  Implement standards of collection  Develop integrated MapObjects (ESRI), CAROL, ClasEvent based on URCHIN  Develop test desktop to Internet Mapping Server still image archive  Propose establishing a national set of standards for DFO Science  Champion national Natural Image Analysis Laboratory CoE

Proposition  Users –discuss and refine standard collection methods –Users include standards in planning their program and setting cost –Users implement standards  Image Management –Advice –Software support –Long term storage

Collection Media and Handling Still  Images collected on a camera should be at the highest resolution possible.  Synchronize camera clock to PC, GPS and UTC.  Filenames should be descriptive, ideally JULDay + UTCtime.EXT (EXT refers to the ‘native’ format generated by the camera.  After download, copies should be made to CD or DVD as backup.  Original CDS should be kept as back-up and forwarded with appropriate metadata to Image Management for long term storage  Any images saved as a JPG will undergo a new compression. When editing a JPG convert image to BMP, do edits then choose the correct JPG Video  Collect moving images to digital tape. Tape inscription should include: Date, Vessel, Station Name/#, Project Id and owner.  Setup Outland to encode GPS time, Lat and Long to the top of the image  Encode serial interface to image using SvModem  Collect ClasEvent* information in real- time. The purpose is to have a minimum interpretation and GPSTime linked for future Discovery.  Make copy of tape and forward with appropriate metadata to Image Management for long term storage

Minimum Standards What needs to be collected and how  GPS should be Differential by use of WASS, dGPS by use of wide area or local station  GPS should be set to upload all available NMEA to a file. Ideally, 1 second intervals of whatever is available. Regulus can be set to log all incoming NMEA. Based on their filenaming standard we recommend that the filename should include a vessel code and Julian Day (eg. Vessel code + JULDAYx.yyT, or 18DA277a.05T (18DA = CCGS Dawson, 277 = Jul day, x= alphanumeric increment for files saved in a given day, YYT = 2 digit year + T= Text)  Sounder should be attached to the GPS and broadcast using the correct NMEA string  Latitude and Longitude accuracy must be set to maximum decimal places and preferably in decimal degrees.  GPS systems and any computers used should be synchronized and set to transmit in UTC.  The GPS receiving antenna should be set as close to the drop point of the instrument, a track point locator attached or offset information provided.  The receiving computer should have at least 2 serial ports or USB multiport capability
