Currently, most of the modelings adopt a ‘loose-couple approach’
(as described by Sui 1998), which use plus-in customer-built
programs to GIS and use commercial GIS package as data
management and display.
D. Navigation and port facilities management
This type of application has evolved from traditional use of
nautical maps to routine channel monitoring, maintenance and
route planning, e.g. NSW Waterway used GIS for waterway
resource management. They also used GIS along with GPS for
planning and real time monitoring the events in the 2000
Olympics water sports (ESRI, 2000). The GIS functions that
require for these tasks with GPS tracking system network
analysis and relevant queries functions of the RDBMS.
E. Coastal Environmental / Hazard assessment:
There are two subcategories in the application: short-term and
long-term tasks. The former is exemplified with monitoring and
predicting oil spilt (Belore, et al., 1990), while the later is
demonstrated in coastal hazard/vulnerability assessment due to
climate change (Lee et al., 1992; Deniels, et al., 1996; Hickey, et
a!., 1997; Zeng and Cowell, 1999; Henneck, et.al., 2000; Esnard
et al., 2001), as well as assessing potential risk area by septic
tanks (Swart, 1995) and coastal wetland assessment (Downs, et
al., 1993).
This type of application is characterised by model integration,
linking other coastal model or multi-models with GIS for
simulating/predicting different scenarios.
F. Coastal management / strategies planning
Similar to Type E, this application also involves assessing
sustainability of environmental system, social and economic
viability (Post and Lunding, 1994). Some of the examples are:
a) Fisheries management planning, site selection for
aquaculture (NSW Fisheries), and Fish closure that convert
the legislation of Gazette or regulation into the spatial
contests.
b) Marine park planning that uses multicriteria analysis to
investigate the interaction between different factors and
constrains, and provides solutions to conflict situations.
c) Aquaculture Industrial Development Plan (see next section)
G. Coastal ecological modeling
This is one of the most challenge applications, ranging from
using Neural Network analysis for identifying boi-regions (Ortiz,
1994), predict stream habitats and fish diversity (Meixler and
Bain, 2000) and applying a multi-dimensional GIS analysis to
track spatial/temporal habitat changes to indicate the quantity of
stream flow essential for maintaining habitats required by aquatic
animals (Parham and Fitzsimons, 2000).
This type of application is focused on integrating ecological
models with GIS for research of ecological system behavior.
In summery, to extend Jones’s work (Jones, 1995) all the
categories of GIS applications in coastal zone is classified as
three levels, and shown in Table 1:
Level 1: as data management and mapping tools
Level 2: as basic data analysis (queries) tool and mapping tools
Level 3: as a decision-supporting tool

Most of current Coastal GIS is still at Level 1 and Level 2. It is
expected that Level 3 will rapidly increase in the near future as
the continuous improvement in GIS functions and user-friendly
interface available in the market.
To demonstrate these three levels of application, an example of
GIS application in Fisheries is given as follows:
A case studies of Fisheries GIS
The outline of Fisheries GIS is given here and the details
articulated by Zeng et al., (1999).
The objective of the fisheries is to ensure the appropriate use of
fisheries resources and conservation of coastal environment. The
role of the Fisheries GIS is, as a managerial tools and decision
supporting tools, to assist in the achievement of the cooperative
goal. All components of fisheries, including routine operation,
fishery management and aquaculture planning, conservation and
research, have to incorporate, share datasets and contribute
value-added datasets for further development.
Based on the business case, the level of each component has
been defined and the appropriate GIS functions are selected as
shown in Table 2.
