Introduction

The software for dbSEABED may be run from any folder on a PC. This folder is called the "host folder" and all file calls by dbSEABED software are relative to it.

The host folder contains the files:

"UserFile.txt" and perhaps also the shortcuts to specific programs.

and the subfolders (click for details):

"_Setup", "_Program", "_Data", "_Polygon", "_Mine", "_RDB", "_ZipBackup" and "_Manual".

The user of dbSEABED need only edit "UserFile.txt" and the large data files in "_Data".

_Setup

This folder contains the files "db8_fac.TXT", db8_dct.TXT" and their WORD *.RTF" equivalents.
The purpose of the latter is to provide a user-friendly formatting for editing and viewing.
After editing the file is 'saved' and 'saved as' "*.TXT".

_Program

This folder contains the various dbSEABED programs:

db9_MNE Processes the data with data mining, parsing and parameter calculations,
to produce EXT/PRS/CLC tables (respectively).
These tables are suitable for input into GIS, relational databases and models.

db8_RDB Creates a Relational Database structure of the unprocessed data,
suitable for Oracle, Access and other similar applications.

db8_ALL Combines the processed EXT, PRS and CLC tables into one ALL table
for maximum coverage with attributes.
Best suits GIS mapping.

db9_ONE Writes one line of output for each sample, taking (in priority) the
PRS, EXT and CLC to minimize null values. Which one is taken is recorded in an audit code.

db8_PLY Pre-processes MID/MIF files representing polygons, polylines and grids
to produce point data "*ASC" files suitable for processing by "db8_Process.bas".

The user has no need to edit these files which are operated from the host folder using the equivalent shortcuts.

_Data

This folder contains the regional core Ascii data files listed in "configur.txt" and applying to each region such as Australasia or US West Coast.
They are the data the dbSEABED programs work on. Some of the files may contain pointers to polyline/polygon data files in "_Polygons".

A subfolder "_Documents" contains the WORD "*.RTF" versions of the Ascii files. Those files aim to make editing and viewing the core data files easier.
After editing, 'Save' the "*.RTF" file, then 'SaveAs' "*.TXT" to the folder above (ie. "_TxtData").

_Polygon

This folder contains the Mid/Mif (Mapinfo) file pairs that hold the polygon, polyline and grid data pointed to in the regional ASCII data files.
For example "ByrB_rck.MID / ByrB_rck.MIF" is pointed to by the primary data file "db8_pwd_.ASC". db8 programs address this topologic data directly within the folder "_Polygons".

The user should prepare the Mid/Mif files externally and move them to the folder.

If they were prepared on a MAC or UNIX, they need to be converted to PC binary format. To do this either:

Open the files ("*.MID" and "*.MIF") in WORD on a PC then save them as text, while retaining their names and extensions.
Import them into MapINFO on a PC, then re-export them over the original filenames.

For further information see the manual page "db8_Polygons.htm".

_Mine

This folder accepts the outputs of the Data Mining program "db9_MNE".
It is also the source of inputs to the pre-GIS programs "db9_ONE" and "db9_ALL".
Once these files are generated they should be copied to the user's folder in which GIS work is to be done.

_RDB

This folder accepts the outputs of the Relational Database generating program "db9_RDB".
Once the RDB files are generated they should be copied to the user's folder in which RDB work is to be done.

_Manual

This folder contains a series of linked web pages that explain features of dbSEABED setup, running and output.
For the present, they will not be linked to the open WWW. New versions should be lodged here after receipt from Sydney University via email or FTP.

The primary manual web page is: "db9_Manual.htm".

The manual folder also covers the important subject of data entry via files such as "db9_input_templates.XLS" (EXCEL).
In addition, there are a few examples of completed EXCEL data entry files for auSEABED.
The actual data entry files for a user's region should not be kept in this folder.

_ZipBackup

This folder contains the WinZIP and initiating files that will be sent from Sydney University from time to time.
Upon imitialization the contained files will be copied to their proper subfolders of the host directory, overwriting older versions of the same name.
