![]() ![]() Reef geomorphology may be the key determinant for the selection of reef fish breeding habitat. These multispecies spawning aggregation sites are generally located near the inflection points of convex-shaped reefs, in 20-40 m water depth, adjacent to sharp shelf edges where water depth drops to several hundred meters. In the Cayman Islands and Belize, fish choose shelf-edge reef promontories for spawning, and share these areas with other species. ![]() Commercially important reef fish such as grouper and snapper use specific geomorphologic locations as spawning grounds throughout the wider Caribbean. Locations of known sites were compiled using published literature and new field surveys and indicate commonality in the underlying geomorphology and species seasonality of reef fish spawning aggregation (FSA) sites throughout the wider Caribbean. Most commercially important reef fishes, including many species of grouper and snapper, travel relatively long distances over the course of days or weeks to aggregate and spawn at very specific times and in very specific places. ![]() The software is a little dated and there is no option for Geodatabase or KML export.Caye Glory and Gladden Spit in Belize, and Grand Cayman East (GCE) and Little Cayman West (LCW) in the Cayman Islands, have a common geomorphologic signature and all harbor important breeding grounds for commercially important reef fishes. ![]() A window similar to that for CSV files (above) is displayed where youshould choose the correct columns.Īs with DBF files you can import an MDB table if it has columnsįor importing VMAP0 data see the chapter on World Map Projections. To be recognised asĪ legitimate vector file by Map Maker the DBF file must contain two columns containing the X and Y ordinates. When a DRA file is exported to a DXF file all the objects a placed in the default DXF layer called “0”.Ĭonventional DBF database files can be used to store point objects. Some vector formats such as MIFĪnd DXF files, contain stylistic information (e.g. The vector file but is stored separately in style files. Remember that in Map Maker information on the appearance of styles is not stored in Note to import Access or Excel data you need Microsoft ADO, ADOX, and Jet Engine As with DBF files you can import an Excel spreadsheet if it has columns for the coordinates. ![]()
