Need for standard folder Data managers deal with many types of files. To these files (and they will be many as continue working), some sort of ‘standard’ folder structure is necessary. This may consist of top levels only (2 or 3 levels within the main folder) Generally the files can be summarized into three categories: Data Products Metadata

Examples PROJECT MOZAMBIQUE – Project files for this area DATA BASEMAP BORDERS – international, national, regional, local GEOLOGY – sediment thickness RELIEF – bathymetry and topography OCEAN WOD – World Ocean Database WOA – World Ocean Atlas OTHER SOURCES – separate folders identified by acronyms are optional here METADATA – Detailed information about any of these datasets – there is always a format

PRODUCTS – files created by the following main programs HDFVIEW – text exports, created by this program, from large grids in HDF or NetCDF IDV – Maps and syntheses made by Integrated Data Viewer ODV – Collections and their products made with Ocean Data View COLLECTIONS - Individual collections of data by data type, area or other original selection criteria IMAGES – Saved images of graphics INTERPOLATIONS – XYZ data triplets exported from ODV’s “surface mode” analyses SAGA – Grids and vector products made by the public domain program GEOIMAGES – Geo-referenced images – includes GeoTIFF etc GRIDS – grids in Saga format, including template grids PROJECTS – lists of objects to place in one map, including the display properties of the objects VECTORS – points, lines, contours, polygons, wind arrows, current arrows; all as either ESRI shapes or Google KML/KMZ
