Overlay Files


There are currently a number of overlay files available for plotting. These contain coastline segments, bathymetry line segments, or boundary line segments (e.g. NAFO lines). Most of these files may be plotted using the Overlay_File() command, and as such will be translated, scaled and clipped to match the current drawing window/ viewport.

The current list of files includes:

wdb1 Entire world coastline at low resolution.
arab Coastline of the Arabian Sea and Indian Ocean at moderate resolution.
coast1 Coastline of Eastern North America at low resolution.
coast2 Coastline of the Maritimes at moderate resolution.
cos_det Coastline of the North Atlantic at moderate resolution.
depthm100/ depthm200 100/200 m bathemetry lines for Eastern North America at low resolution.
DepthFxxxx Bathemetry lines for Maritimes at moderate resolution, where xxxx in the file name represents depth value in fathoms.
DCxxxx Bathemetry lines for North Atlantic at moderate resolution, where xxxx in the file name represents depth value in metres.
Nafo area 4,5 4,5 BW.art Mac Illustrator Base Map for the Scotian Shelf (see the example "Base MapsBase Maps").
gfstrata Groundfish survey strata boundary linesGroundfish survey strata boundary lines for the Scotian Shelf.
icj boundary line CAN/US ??.
Machias CDN/ Machias USA boundary line.
Passamaquoddy another boundary
Passgm another boundary

Additional bathymetry lines for the Maritimes coast may be found in the Overlays\GOM folder.
The 4 digits in the filenames represent depth values in metres.

Overlay Scripts

There are currently a few script files which may be used to control the drawing of overlay files or boundaries. These scripts enhance the drawing of the embeded data, but typically require some study to use them to their fullest.

The current list of files includes:
nafolines.script draws NAFO boundary lines.
arabind.script draws the coastline of the Arabian Sea and Indian Ocean as shaded polygons.
natl.script draws the coastlineof the North Atlantic Ocean as shaded polygons.
