Start SeaGrid -- Execute "seagrid" (no argument) at the Matlab prompt. A blank "SeaGrid" window will appear, as show above.
Help -- "SeaGrid" is supported by a comprehensive "Help" system, accessible through the "Help" menu. Topics can be reached through individual menu items, or through the dialog shown here. (Actual SeaGrid menu headings are surrounded by triangular brackets, to distinguish them from Matlab's own menus.)
Load Coastline (optional) -- Select the "SeaGrid/Load/Coastline File..." menu item, then select the "amazon_coast.mat" file, located in the "test_data" subfolder. The Amazon coastline will be drawn in the main "SeaGrid" window. A coastline consists of one or more closed polygons specified by (longitude, latitude) pairs, separated by NaNs.
Load Bathymetry (optional) -- Select the "SeaGrid/Load/Bathymetry File..." menu item, then select the "amazon_bathy.mat" file, located in the "test_data" subfolder. The locations of bathymetric points near the Amazon will be drawn in the main "SeaGrid" window. Zooming (see below) will show them to be discrete points. The bathymetric data will be gridded below.
