Application of Remote Sensing. Urban Planning ...

Urban land use and land cover mapping: Remote sensing can be used to map and monitor land use and land cover changes in urban areas, such as the expansion of housing developments, commercial areas, and transportation infrastructure.

Identification of areas of urban sprawl: Remote sensing can be used to identify areas of urban sprawl, which can help in planning for sustainable growth and managing land use.

Building inventory and change detection: Remote sensing can be used to create a detailed inventory of buildings and other structures in urban areas, and to detect changes in the built environment over time.

Transportation planning: Remote sensing can be used to map and monitor transportation infrastructure, such as roads, bridges, and rail lines, which can help in planning for new transportation projects and managing existing infrastructure.

Mapping of green spaces: Remote sensing can be used to map and monitor the distribution and health of green spaces in urban areas, such as parks, gardens, and open spaces, which can help in planning for sustainable urban environments.

Identification of potential hazards: Remote sensing can be used to identify and map potential hazards in urban areas, such as flooding, landslides, and wildfire risks, which can help in disaster risk reduction and mitigation.

Lighting and energy efficiency: Remote sensing can be used to assess the lighting and energy efficiency of buildings and other structures in urban areas, which can help in planning for sustainable urban environments.

Urban heat island effect: Remote sensing can be used to monitor the urban heat island effect, which can help in identifying areas with high temperatures, and in planning for cooling strategies.

Geography of Landslides. Mitigation and Resilience.

A landslide is a geological event in which a mass of rock, earth, or debris moves down a slope under the force of gravity. Landslides can range in size from small to large and can be triggered by natural events such as heavy rainfall, earthquakes, or volcanic activity, or by human activities such as construction or mining. The geography of landslides is affected by a variety of factors that can increase the likelihood of landslides occurring in a particular area. These factors include slope angle and steepness, the type of soil and rock present, the climate and weather patterns of the region, the presence or absence of vegetation, and human activities such as construction, mining, and deforestation. Areas with steep slopes are more prone to landslides because gravity has a stronger effect on loose soil and rock, making it more likely to move downhill. Similarly, areas with loose, sandy soil or weak, fractured rock are more prone to landslides because they are less stable and more easil...

Geography of Flood. Types. Charector.

The geography of floods refers to the characteristics and patterns of floods in different geographic regions. Floods can occur in various landscapes, such as mountains, plains, coastal areas, and urban environments. The geography of a region plays a significant role in determining the frequency, magnitude, and impacts of floods. Some of the factors that influence the geography of floods include: Topography: The shape and elevation of the land can affect the flow and accumulation of water during a flood. For example, flat terrain can lead to slow-moving and widespread flooding, while steep slopes can result in flash floods and landslides. Climate: Regions with high rainfall or snowmelt can experience more frequent and intense floods, while dry regions may experience flash floods due to sudden, heavy rainfall. Hydrology: The characteristics of a river basin, such as its size, shape, and water flow, can influence the severity of a flood. For example, large river basins with extensive floo...

Landslides. TYPES OF LANDSLIDES The term "landslide" describes a wide variety of processes that result in the downward and outward movement of slope-forming materials including rock, soil, artificial fill, or a combination of these. The materials may move by falling, toppling, sliding, spreading, or flowing. The animated GIF shows a graphic illustration of different types of landslides, with the commonly accepted terminology describing their features. The various types of landslides can be differentiated by the kinds of material involved and the mode of movement.

Flood prone regions India

Floods are natural disasters characterized by the overflow of water onto normally dry land. Various factors contribute to floods, including intense rainfall, rapid snowmelt, storm surges from coastal storms, and the failure of dams or levees. The geographical explanation involves understanding the key components of flood-prone regions: 1. Proximity to Water Bodies: Flood-prone regions are often situated near rivers, lakes, or coastal areas. These locations are more susceptible to flooding as they are in close proximity to large water sources that can overflow during heavy precipitation or storms. 2. Topography: Low-lying areas with gentle slopes are prone to flooding. Water naturally flows to lower elevations, and flat terrains allow water to accumulate easily. Valleys and floodplains are common flood-prone areas due to their topographical characteristics. 3. Rainfall Patterns: Regions with high and concentrated rainfall are more likely to experience flooding. Intense and prol...
