Disadvantage of Raster data

  1. Difficult to represent: It is difficult to represent linear features such as accurate network linkage are difficult to establish.
  2. Vector Form: Most input data is in vector form, therefore data must undergo vector-to-raster conversion.
  3. Do not Conform: Most output maps do not conform to high quality cartographic needs.
  4. Large size: Larger file size.     
  5. Edit difficult: Difficult to edit.
  6. Difficult to build relation: Difficult to build topographic relationship.
  7. Inefficient projection: Inefficient projection transformation.
  8. Hard to Represent: Hard to represent objects less than cell size.
  9. Generates Huge Data: Finer resolution generates huge data.
  10. Discrete Feature: Highly generalized representation of discrete features.
  11. Limited interactivity: Limited interactivity 
  12. More primitive: More primitive analysis algorithm.

Concentric zone theory

Theories of City Structure-Concentric Zone Theory Introduction: The Concentric or Zonal Theory of urban landuse was first proposed in 1923 by E.W. Burgess. He was a sociologist. The idea behind the concentric model is that the development of a city takes place outwards from its central area in a series of concentric circles to form zones.  Assumption:        i.           Cultural & social heterogeneity of the population.       ii.           Commercial-industrial base to the economy of the city.     iii.           Private ownership of property & economic competition for space.     iv.           Expanding area & population of the city.       v.    ...

Future scenario of Renewable Energy Resource in India

Future scenario of Renewable Energy Resource in India: The Indian Government has increased the target of renewable energy capacity to 175 GW by the year 2022, which includes 100 GW ( gigawatts) from solar, 60 GW from wind, 10 GW from bio-power & 5 GW from small hydro-power. Source 2022 Target (GW) Solar 100 Wind 60 Bio-Power 10 Small Hydro-Power 5 Future Scenario of Solar Energy:       Solar power in India is a fast developing industry.       The country’s solar installed capacity reached 29.55 GW as of 30 June 2019.       India has become globally the lowest cost producer of solar power.       The Indian Government has increased the target of renewable energy capacity to 175 GW by the year 2022, which includes 100 GW from solar. Advantage: Advantage of using solar energy is its eco-friendly nature. It does not release CO 2  and o...

Different Types of Tide

Tides are periodic, short-term changes in the height of the ocean surface at a particular place caused by a combination of the gravitation force of the moon & sun & the motion of the Earth. Sparing Tides: When the moon, sun & earth are located along the same line, then the attraction power of the moon & sun is intense. For this high tide is created, this types tide is called sparing tides. Fig: Sparing Tide Neap Tides: When the sun & moon are at a 90° angle to the earth, then their rotation is reduced to earth. Because the moon & the sun do not draw the opposite direction, so the tidal velocity decreases. And its height is lower than the normal tide. That types tide known as neap tides. Fig: Neap Tide Tropical & Equatorial Tides: When the moon is perpendicular to the tropic of cancer, then the force of attraction is relatively high & created high tide. This tide occurs twice in a year. This types tide is known as tropical tides.  ...
