It can combine different types of information such as roads, buildings, rivers, and vegetation on a single map. This <\/span><b>helps people easily view, analyze, and understand<\/b><span style=\"font-weight: 400;\"> patterns and relationships between different geographic features.<\/span><\/p>\n<h2><b>Types of Geographic Information System Data<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">GIS data is mainly of two types: <\/span><b>Vector data and Raster data.<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Vector data<\/b><span style=\"font-weight: 400;\"> represents <\/span><b>geographic features using points, lines, and polygons.<\/b><span style=\"font-weight: 400;\"> Points show specific locations like schools or wells, lines represent features such as roads, rivers, and railways, and polygons indicate areas like forests, lakes, or administrative boundaries. It is useful for showing clear boundaries and precise locations on maps.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Raster data<\/b><span style=\"font-weight: 400;\"> represents the <\/span><b>Earth\u2019s surface as a grid of small cells (pixels), <\/b><span style=\"font-weight: 400;\">where each cell contains a value representing features like temperature, elevation, rainfall, or land cover. It is commonly used in satellite images, aerial photographs, and environmental studies, especially for showing continuous features such as climate patterns and terrain.<\/span><\/li>\n<\/ul>\n<h2><b>Geographic Information System Applications<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">GIS is widely used in many fields because it helps in analyzing geographic information and improving planning and decision-making.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Urban Planning:<\/b><span style=\"font-weight: 400;\"> GIS plays an important role in city planning and development. It helps planners map land use and divide areas into residential, commercial, industrial, and recreational zones. It also supports infrastructure planning by analyzing population distribution, terrain, and existing facilities.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Environmental Management:<\/b><span style=\"font-weight: 400;\"> GIS is very useful for protecting natural resources and monitoring environmental changes. It helps track deforestation and changes in forest cover using satellite data. It can also identify sources of pollution in air, water, and soil. In wildlife conservation, GIS helps map animal habitats, migration routes, and areas affected by human activities, which supports better conservation planning.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b><a href=\"https:\/\/vajiramandravi.com\/upsc-exam\/disaster-management-in-india\/\" target=\"_blank\">Disaster Management<\/a>:<\/b><span style=\"font-weight: 400;\"> GIS is an important tool in disaster management because it helps in preparedness, response, and recovery. It can identify areas that are prone to floods by studying elevation and river systems. For earthquakes, GIS helps locate fault lines and identify vulnerable buildings and populations. During disasters, GIS can assist in planning evacuation routes, locating relief camps, and coordinating rescue operations.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Agriculture:<\/b><span style=\"font-weight: 400;\"> GIS supports modern agriculture by helping farmers make data-based decisions. It is widely used in precision farming, where farmers analyze crop health, soil quality, and irrigation needs. GIS can also help study soil fertility, moisture levels, and pH values.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Space Research:<\/b><span style=\"font-weight: 400;\"> GIS is also used in space exploration and planetary studies. Scientists use GIS to create maps of celestial bodies such as the Moon and Mars. These maps help researchers study surface features and choose suitable landing sites for space missions. When combined with remote sensing data, GIS helps scientists analyze both Earth\u2019s surface and other planetary environments.<\/span><\/li>\n<\/ul>\n<h2><b>Government Initiatives Related to GIS in India<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The Government of India has launched several initiatives to promote the use of Geographical Information System (GIS) and geospatial technology for better planning, governance, and development. These initiatives help improve land management, infrastructure planning, disaster response, and digital governance.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b><a href=\"https:\/\/vajiramandravi.com\/current-affairs\/national-geospatial-policy-2022\/\" target=\"_blank\">National Geospatial Policy 2022<\/a>:<\/b><span style=\"font-weight: 400;\"> Aims to make India a global leader in the geospatial sector by promoting the use of geospatial data, developing geospatial infrastructure, improving skills, and encouraging private sector participation.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>SVAMITVA Scheme:<\/b><span style=\"font-weight: 400;\"> Uses GIS and drone mapping to provide property cards to rural households and digitize land records.
