(b) Explain the functions of G1S.
(c) Explain the functions of GPS.
Answer:
(a) Meaning – The data which are collected for the first time by a researcher or groups of researchers, institution or organizations are called Primary sources of data.
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 :

  1. Telephone interview : In this method, the researcher/interviewer can collect the information over the telephone.
  2. 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.

Meaning – The data those have been collected and analyzed already by some departments, organizations, NGO’s etc… are called Secondary data.
Types of Secondary sources of data
1. Published sources – There are 5 types

  • International publications: In this publications-year books, monographs and reports are published by different agencies of the united nations.
  • Government publication: These publications comprise the census of India published by office of the register general of India.
  • Smi Government publication : In this category the publications and reports of corporations, boards, urban development authorities etc …
  • Private publication : The research reports, surveys, year-books and monographs are published.
  • Newspapers and Periodicals : The daily news papers and periodicals or magazines are easily accessible.

2. Unpublished sources – There are 3 types.

  • Government Documents : The reports, papers, findings, monographs and documents are prepared a$d maintained as unpublished records at different levels of Government.
  • Government Records : The corporations, boards, district councils and civil departments prepare and maintain the periodical reports and the development plAnswer:
  • Private Documents : The companies, trade unions, different political and non-political organizations and resident welfare associations are having unpublished reports and records.

(b) 1. Capture data: Geographical data can be collected/captured from various sources like hard copy, map through tophosheet, digital data, through GPS, Secondary data through published tables.

2. Storing data: Geographical data once captured, it needs to transform from Analogy into digital format and to be stored in computer for further analysis.

3. Query: Once you have a functional GIS containing your geographical information, you can begin to ask a simple questions.

4. Analysis : There are 3 types

  1. Proximity Analysis : Proximity queries find features with in a certain distance of other features.
  2. Overlay Analysis : It is simplest, this could be a visual operation, but analytical operations require One or more data layers to be joined physically.
  3. Network Analysis : Anetwork is a set of edges and junctions that are Topologically connected to each other.

5. Display: Once analysis is done maps, diagrams, graphs and tables are to be designed and same has to be displayed over computer moniter.

6. Output: This is final, stage of GIS function where in the maps, data tables etc…. can be printed to have hard copy as output.

(c) 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.

1. Navigation: In navigation, by using GPS can save countless hours in the field. Any feature, even if it is under water, can be located upto one hundred meters simply by scaling coordinates from a map, entering way points & going directly to site.

2. Remote sensing and GIS : GPS positioning can be intergrated into remote – sensing methods such, as Photogrammetry and aerial scanning, magnetometry, and video technology using DGPs techniques.

3. Surveying/Mapping: The high precision of GPS’ carries phase measurements, together with appropriate adjustment algorithum, provides an adequate tool for a variety of tasks for surveying and mapping.

4. Geodesey: Geodetic mapping and other control surveys can be carried out effectively using high grade GPs equipment.

5. Military: The GPs was Primarily developed for real time military positioning. Military applications include airbone, marine and land navigation.
