Thus, irrigation becomes necessary on account of following reasons.

  • Nature of rainfall Due to irregular, uncertain and limited rainfall scarcity of water is caused so, need for irrigation arises.
  • Nature of soil There is greater need of irrigation in sandy soil.
  • Probability of DroughtAt places of droughts irrigation is essential.

Types of Primary data collection:-
1. Through Personal interview : Personal interviews are the most commonly used method of collecting data, because the interviewer has the opportunity of explaing the study and answering any question, here the researcher gets direct information from the respondents.

2. By Personal observations: It refers to the collection of data or information by individual or group of individuals, through direct observations in the field.

3. By Questionnaire: The most common method used in surverys is the Questionnaire. In this method, simple questions and their possible answers are written on a plain paper, and the respondents have to tick mark the possible answers from given choices.

4. Others methods :

  • Telephone interview : In this method, the researcher/interviewer can collect the information over the telephone.
  • Measuring properties : In this method, the data about properties of soil, and water collected directly from the field by measuring their characteristics using soil and water quality kit.

(b) Explain the segment of GPS
There are three segments of GPS:-
1. The space segments : The satellites of GPS are launched and positioned at an altitude of approximately 20200 km which is almost more than three times of the earth’s radius. The space segment consists of a constellation of 24 functioning GPs satellites located in 6 orbital plane with 4 satellites in each orbital plane. The time for the satellite to complete
one revolution around the earth is 11 hrs and 58 minutes.

2. The control segment: The control segment consists of facilities necessary for satellites especially healthy monitoring, telemetry, tracking command and control clock error ‘ computation .of satellites. There are 5 GPS stations spread over the earths surface they arc –

  • Hawaii
  • Colorado spring
  • Ascension Island
  • Diego Garcia
  • Kwajalein.

3. The user segment: It is a total user and supplier community, both civilian and military. The user segment consists of all earth – based GPS receivers. Receivers very greatly in size and complexity, through the basic design in rather simple. The space and control segments are largely transparent to the operations of navigation functions.

2. Radiation and the Atmosphere (B) – As the energy travels from its source to the target, it will come in contact with and interact with the atmosphere it passes through.

3.,Interaction with the Target (C) – Once the energy makes its way to the target through the atmosphere.

4. Recording of energy by the sensor (D) – After the energy has been scattered by or emitted from the target we require a sensor to collect and record the electromangnetic radation.

5. Transmission, Reception and Processing (E) – The energy recorded by the sensor has to be transmitted, often in electronic form, to a receiving and processing station where the data are processed into an image.

6. Interpretation and Analysis (F) – The processed image is interpreted, visually/or digitally or electronically, to extract information about the target which was illuminated.

7. Application (G) – The final elements of the remote sensing process is acheived when we apply the information to better understand it and solve a particular problem.
