Case Study

ScenarioTo effectively improve the pollution control and management in Yilan, the Department of Environmental Protection Yilan, Taiwan planned to establish a platform named Yilan Pollution Control GIS with SuperGIS Server. SuperGIS Server allows organizations to distribute GIS data and web services easily via the Internet.

The project is established step by step and comprises GIS data collection, prototype system development, system expansion, and platform development and operation to meet the governor’s expectation.

The Environmental Pollution Control GIS platform currently focuses on integrating all kinds of pollution modeling analyses such as marine and air pollutions which enable decision-makers to combine the data with existing pollution layer for further application use.

GoalsThe aim of this project is to develop an application-oriented platform where the staff of Department of Environmental Protection Yilan can obtain and combine various integrated information about marine and air pollution, models, and environmental related researches to fulfill application requirements.

Environmental Pollution Control GIS

Goals

- The aim of this project is to develop an application-oriented platform where the staff of Department of Environmental Protection Yilan can obtain and combine various integrated information about marine and air pollution, models, and environmental related researches to fulfill application requirements.

Results Software Used

- Microsoft Windows Server 2008- Microsoft SQL Server 2008- SuperGIS Server

- By using the integrated marine and air pollution data, modeling, and spatial analysis provided by Pollution Control GIS, users can maximize overall work efficiency and formulate effective plans for better disaster prevention and management. The project successfully brings benefits to the Department of Environmental Protection Yilan.

ResultsThe overall functionality of Environmental Pollution Control GIS includes positioning, layer management, marine and air pollution modeling, and data management.

developed by National Oceanic and Atmospheric Administration to generate some analytic results. These results have greatly assisted decision-makers in understanding the possible extent, area, and disaster-effected population of hazards and establish possible prevention programs in advance.

Web GISThe system is developed with SuperGIS Server to establish the map server and provide real-time spatial data to users.

Database ManagementThe system adopts Microsoft SQL 2008 as the database management software to manage spatial data and optimize query efficiency.

Data IntegrationThe data source contains the information about cadastre, images, pollution surveys, water and other basic maps. Most importantly, the system allows each unit to collect and analyze the data from other units to display the analyze results on the system.

Platform PlanningThe platform includes public query system, intranet system, and back-end data management system. The public query system allows the public to query the pollution data and with basic map navigation tools, such as spatial positioning, map measuring. The intranet system offers comprehensive map information and related simulation tools. The back-end data management system allows to add new layers, update data, and manage authorization.

Layer Management and Attribute Query

Air Pollution Modeling & IntegrationA disaster may cause significant damage or loss of life. In this case, how to prevent and minimize the effects of disasters becomes more and more important to the emergency reaction team. In 2011, the staff of Department of Environmental Protection Yilan uses the air pollution modeling & analysis software, ALOHA,

Variety of data search and export toolsThe system is designed to satisfy users’ requirements of data search and export functions such as rectangle selection, polygon selection, circular selection and multiple selection to obtain information that they are interested in, also ensuring that the data can be reused efficiently.

Data managementThe data management platform of the system provides users with the flexibility to manage data and add new layers and fields based on the different requirements. In addition, the layer management tool allows users to easily configure the settings for adjusting the classifications and extents of layers to display.

PositioningThe positioning function contains coordinate positioning, road positioning, address positioning, landmark positioning, layer positioning, and cadastral positioning. Users can use the layer positioning tool to zoom to the location they would like to query. and receive cross-layer information through keyword search.

Layer Management and Attribute QueryBesides getting the real-time traffic information on mobile phones through the application, the system also provides web page for the public to query online.

Marine Pollution SimulationThe marine pollution simulation software, GNOME, developed by National Oceanic and Atmospheric Administration U.S. is able to simulate and demonstrate the general situation of oil spills off the coast of Yilan. The emergency reaction team can utilize the useful layer information combined with demonstrations to make crucial decisions.

Benefits of Pollution Control GISThe Pollution Control GIS successfully integrates the simulating results of marine and air pollution, offering up-to-date pollution data and feasible spatial statistical analyses to decision-makers for further application use.

In the future, the system aims to become a versatile support platform of integrating any development devices for offering the efficient data collection service, the enhanced system environment, and the smoother investigations and operations.
