function README % ************* Seagrid Download ************* % % From "crusty.er.usgs.gov/seagrid/", use anonymous ftp % to download "seagrid_install.p", "form_install.p", and % "proxy_install.p". Each P-file installer is a Matlab % function that creates and populates a directory of the % corresponding name.The versions for Matlab 5.0/5.1 % use ".p50" as the extension. Also download the "m_map" % toolbox of Rick Pawlowicz. It contains unbundled text % and binary files. % % Download "amazon_coast.mat" and "amazon_bathy.mat"; % both are binary Matlab Mat-files. Put these files in % the "seagrid/test_data" directory. % % A script called "seagrid_test" can be run to automatically % load the test data into SeaGrid. If it fails, then probably % some software is missing, or the Matlab path needs adjustment. % % ************* Seagrid Tutorial ************* % % Start by executing "seagrid" at the Matlab prompt. % Its many features are described in the "help" entries, % accessible through the "Seagrid/Help" menu. % % Select a projection by invoking the "View/Setup" % menu item to display the "SeaGrid Setup" dialog. % The default is "Mercator". % % The next task is to open a coastline file, if any, % followed by a bathymetry file, if any. The required % formats are given in the "help". These data will be % plotted on the current projection. The plot units % can be toggled between "Degrees" and "Kilometers" % by using the "View/Units" menu item. % % Then, four corner-points need to be placed on the map % by simple clicking. These points are draggable, so their % exact placement is not critical. % % Macintosh clicking: #1 = simple click; #2 = shift-click; % and #3 = option-click. % % Once the four corner-points have been placed, the map % becomes zoomable, using the "zoomsafe" protocol. See % "help zoomsafe". % % To add an edge-point, click on any edge, dragging if % desired. As with corner-points, edge-points are draggable % at any time. Also, an edge-point can be deleted by clicking % on it with button #3. The boundary is displayed with cubic % splines that pass through the corner-points and edge-points. % % The number of gridlines is adjustable through the "Setup" % dialog (select the "View/Setup" menu item). % % The grid cell spacing can be manipulated by invoking % the "View/Spacers" menu item. Clicking (button #1) and % dragging a spacer will rearrange the grid lines smoothly % to mirror how closely spaced the spacers themselves are. % The number of spacers can be changed with the % "View/Spacer Count" menu item. % % The default grid cell spacing can be expressed as a % function through the "View/Default Spacing" menu item. % The subsequent dialog accepts functions of "s", the % relative distance [0:1] along each of the two principal % edges of the boundary. The beginning of the first % principal edge is marked by "*", and the boundary always % runs counter-clockwise always. This geometry can be rolled % with the "View/Roll" menu item. % % The current grid can be saved for later retrieval, using % the "Seagrid/Save" or "Seagrid/Save As" menu items. The % most recently saved grid is available through the % "SeaGrid/Revert To Saved" menu item. % % The grid can be masked with the "Compute/Land Mask" menu, % to mark those cells whose centers fall on land. Also, the % "Mask Tool" can be invoked through the "Compute/Mask Tool" % menu item to allow manual toggling of the mask. Finally, % the "Compute/Erase Mask" menu can be used to erase the % current mask. % % NOTE: the manual masking changes do not become effective until % the "Mask Tool" is dismissed by choosing the "Compute/Mask Tool" % menu item again. % % To convert the saved SeaGrid output to a SCRUM or ECOM file, % execute "seagrid2scrum" or "seagrid2ecom". Both routines will % prompt for filenames if none are provided on the command-line. % See "help" for each. % Copyright (C) 1999 Dr. Charles R. Denham, ZYDECO. % All Rights Reserved. % Disclosure without explicit written consent from the % copyright owner does not constitute publication. % % Version of 05-Aug-1999 14:26:12. % Updated 08-Oct-1999 09:41:57. help(mfilename)
