1. Geographical Information Systems (GIS) Geographical Information Systems (GIS) are powerful tools that create, manage, analyze, and map all types of spatial data. This technology is revolutionizing how organizations across various fields communicate information, perform analysis, and solve complex problems worldwide.

2. What is GIS? Spatial System GIS is a geographical information system that creates, manages, analyzes and maps all types of data. Integration GIS systematically integrates hardware and software for capturing, storing, displaying, updating, manipulating and analyzing spatial data. Widespread Use Millions of organizations in virtually every field are using GIS to make maps that communicate, perform analysis, share information and solve complex problems around the world. Changing the World The use of GIS is changing the way the world works by providing new insights and capabilities.

3. Interdisciplinary Nature of GIS 1 Geodesy GIS incorporates projection, surveying, and cartography. 2 Remote Sensing GIS utilizes data collected from remote sensing technologies. 3 Photogrammetry GIS integrates photogrammetric techniques for accurate spatial measurements. 4 Environmental Science GIS is widely used in environmental studies and analysis.

4. Additional Fields in GIS 1 City Planning GIS is an essential tool in urban development and city planning processes. 2 Cognitive Science GIS incorporates aspects of cognitive science in its user interface and data representation. 3 Data Science GIS heavily relies on data science techniques for analysis and interpretation.

5. Capabilities of GIS Multi-layer Visualization GIS can show many different kinds of data on one map, such as streets, buildings, and vegetation. Pattern Analysis This enables people to more easily see, analyze, and understand patterns and relationships. Data Correlation By relating seemingly unrelated data, GIS can help individuals and organizations better understand spatial patterns and relationships.

6. Components of GIS: Maps Geographic Container Maps are the geographic container for the data layers and analytics one wants to work with. Easily Shared GIS maps are easily shared and embedded in apps. Accessible GIS maps are accessible by virtually everyone, everywhere.

7. Components of GIS: Data 1 Integration GIS integrates many different kinds of data layers using spatial location. 2 Geographic Component Most data has a geographic component. 3 Data Types GIS data includes imagery, features, and base maps linked to spreadsheets and tables.

8. Components of GIS: Analyses Spatial Analysis Spatial analysis lets you evaluate suitability and capability, estimate and predict, interpret and understand, and much more. New Perspectives GIS analysis lends new perspectives to your insight and decision-making. Complex Problem Solving GIS analyses enable solving complex spatial problems efficiently.

9. Components of GIS: Apps 1 Focused User Experiences Apps provide focused user experiences for getting work done and bringing GIS to life for everyone. 2 Cross-platform Compatibility GIS apps work virtually everywhere: on mobile phones, tablets, in web browsers, and on desktops. 3 Accessibility GIS apps make complex spatial data and analysis accessible to a wide range of users.

10. Important Functions of GIS Data Pre-processing GIS prepares raw data for analysis. Data Manipulation & Retrieval GIS allows for efficient data handling and access. Data Analysis GIS provides tools for in-depth spatial analysis. Data Display GIS offers various ways to visualize spatial data.

11. Advantages of GIS Efficient Decision Making It helps the planners in efficient & cost effective decision making based on multiple scenarios available. Data Integration GIS allows integration of all types of data together based on geographical & locational components of data. Application Oriented GIS is application oriented, making it versatile for various fields.

12. Advantages of GIS Easy Data Revision Frequent revision of digitized GIS data is possible. Temporal Monitoring Changes over time can easily & rapidly monitored through GIS. High Quality Output GIS technology enables high quality output for various applications.

13. Application of GIS in Fisheries: Marine and Inland Waters 1 Water Conditions and Habitats GIS data gives information about marine and inland water conditions and habitats. 2 Aquaculture Site Selection It helps in Identification of suitable sites for freshwater & brackish water aquaculture. 3 Fishery Management Tools GIS based studies is helpful in developing management tools for fishing effort restriction, avoidance of juvenile exploitation, reducing the bycatch, conserving biodiversity and endangered species, identifying critical ecosystems, declaration of fishery refugia and marine protected areas (MPA).

14. GIS in Fisheries: Biodiversity and Species Distribution Biodiversity Assessment The database on distribution created in GIS format can be used for assessing biodiversity, understanding the importance of the fishing ground in terms of conserving biodiversity and sustaining fisheries. Species Composition Changes GIS provides an opportunity to understand the changes in the species composition in a particular fishing ground over a period of time. It provides information on the status of fishery and biodiversity. Water Pollution Assessment It is helpful to assess the status of water pollution in fishing grounds.

15. GIS in Ocean Management and Regulation 1 Commercial Activities Monitoring It is extensively used in the ocean for collecting information regarding various commercial activities. 2 Illegal Fishing Detection It is used to determine the location of illegal fishing operations. 3 Resource Management GIS collects data for Management of marine fisheries & coastal regulation zone. Data is useful in resource allocation and regulation.

16. GIS in Coastal Zone Management Macro and Micro Planning GIS collects data essential required for macro and micro level planning for coastal zone management. Resource Monitoring Helps to monitor coastal resources, studying coastal land forms. Aquaculture Site Selection Assists in selecting sites for aquaculture in coastal areas.

17. GIS in Environmental Management 1 Wetland Mapping GIS provide wetland mapping and design projects for wetland conservation. 2 Navigation Safety GIS encourage safe navigation in waterway. Ferry paths and shipping routes are identified for better routing. 3 Environmental Impact Assessment Environmental Impact Assessment (EIA) can be carried out with the help of GIS, by integrating with various GIS layers.

18. GIS in Disaster Management Risk Management GIS can be helpful in risk management and its analysis by displaying areas that are likely to be prone to natural or man-made disasters. Preventive Measures By identifying disasters, preventive measures can be developed using GIS data. Mitigation Planning GIS also become well developed and successful tools for disaster management and its mitigation.

19. Additional Applications of GIS in Fisheries 1 Fishing Pressure Analysis GIS based mapping is helpful in addressing issues such as intensity of fishing pressure, vulnerability of ecosystem and species to decide upon the introduction and reduction of fishing fleets, rationalization of fishing operation, seasonal and spatial closure of fishery. 2 Land-use Pattern Study Study of land-use pattern including mangroves & forest cover of a particular area. 3 Water Resource Planning Planning for water body resource zonation & mapping of aquatic species. 4 Fish Disease Management Fish disease modelling & management using GIS data.

20. GIS in Fisheries: Advanced Applications Production and Consumption Analysis Study of temporal / spatial changes in fish production & consumption. Habitat Characterization Distribution of different fish species in relation to physical habitat characteristics. Supply-Demand Analysis Study of spatial variations in demand / supply balance. Product Marketing Marketing of fishery products using GIS data. Stock Assessment GIS data helps in Stock assessment, prediction, and analyses.
