Habitat and Communities: Google Earth® Maps

The link below allows you to access Google Earth® zipped keyhole markup (*.kmz) files related to Council developed management measures.  Most of the files show coordinates and lines describing various groundfish area closures.    These closed areas are mapped using waypoints published by NMFS (see NMFS Groundfish Closed Areas webpage) and associated boundary schedules.  Depictions of these area closures may be revised from time to time based on regulation changes described in NMFS notices.

The kmz files have to be downloaded or launched from the Council’s FTP Site.  These files are currently available:

  • 2019-20 Nontrawl RCA.kmz displays the nontrawl RCA waypoints and boundary lines for at the beginning of the 2019-2020 biennial period.
  • 2019-20 Trawl RCA.kmz displays the trawl RCA waypoints and boundary lines for at the beginning of the 2019-2020 biennial period.
  • 2019-20 Depth Contours.kmz are the waypoints and associated lines representing the various depth-contour based management lines in use during the 2019-20 biennial management period.
  • GCA_nonRCA.kmz displays Cowcod Conservation Areas (CCAs) in the Southern California Bight and Essential Fish Habitat conservation areas as polygons.
  • RCA_Latitude_Boundaries.kmz represents the latitudes at which RCA boundaries may change from the approximation of one depth contour to another.
  • West_Coast_EEZ.kmz displays an approximation of the boundary of the west coast Exclusive Economic Zone.

Note: Please install Google Earth first to view these files.  If you don’t have it installed, you may download a copy of the software from Google’s website to install on your computer.

You may then either save one or more files to your local drive and then open them with Google Earth® or launch a particular file of interest.  Only features associated with opened files are displayed (likely found in your Temporary Places folder). Check/uncheck folders to change which features to view.  Click on the folder name to view a description of the folder contents.

Google Earth® allows you to view the depth profile for a selected line.  First, in the Places pane right-click on a line folder and choose Properties, Altitude and choose “Relative to seafloor” from the list. Click OK to exit the dialog. Right click the line folder again and choose Show Elevation Profile.  A panel is displayed at the bottom of the window showing a profile of the depths along the line.
