Remote sensing is the method of collecting information about an object with the help of distantly placed sensors without touching

C. Organization

Organization is not a component of GIS.

Maximum horizontal range :-

sin 2theta = 1

sin 2theta = sin 90°

theta = 45°

R = u² sin2 (45°)/g

R = u² sin 90° /g

R = u²/g

Wiki mafia is a software that will help us to locate a place. 

For example, of you house is in Thrissur your house will be 10.5276°N, 76.2144°E, of it is in Trivandrum city 8.5241 °N, 76.9366°E of it is in Kannur 11,8745°N, 75.3704°E.

Satellite-based Navigation System: Nowadays, satellite-based tracking system are used for monitoring the location and movement of objects on the earth’s surface Global positioning system helps sensing the latitudinal and longitudinal locations and elevation of objects. In this system, 24 satellites are placed at six different orbits at different attitudes.

Our ancestors made map after collecting information about the surface of the earth and survey of earth’s surface which lasted for a long time. Aerial photography which developed later made map-making quite easy. Satellite remote sensing and geographical information systems which developed in the 1960s as a result of the progress in science and technology paved the way for map-making efficient and fast.

2. Glucagon – Liver

a. Indicates the limitation of aerial remote sensing 

b. Indicates the merit of aerial remote sensing. 

c. Geostatiount satellites 

d. Sun svplelrronous satellite

• Cost. The underlaying cost involved in a relational database is quite expensive.
• Performance. Always the performance of the relational database depends on the number of tables.
• Physical Storage.
• Complexity.
• Information Loss.
• Structure Limitations.

GPS has significant role in the present-day world from tracking not work analysis etc.

C. Spaghetti

Spaghetti data model is the simplest data structure.

Pollen tube.

Acquired Immuno Deficiency Syndrome.

B. Irregular

Natural features are generally more Irregular in shape.

(A) A cure for deadly diseases is being desperately searched by researchers.

In a database table, a field is a data structure for a single piece of data.

Uses : Helps in sensing latitudinal and longitudinal location, elevation of objects on earth’s surface along with corresponding time.

Working : GPS has a group of 24 satellites that orbit around the earth in 6 different orbits between the altitudes 20000 and 20200 km above the earth’s surface to locate objects. We can locate the places with the help of signals received from the satellite in our handheld device. A GPS should receive signals from at least 4 satellites to display the information like latitude, longitude, elevation and time of a place.

Parent to offsprings.

Primary consumer.

Typhoid is Communicable type of diseases 

The first GPS satellite was launched in the year of 1978.

Energy conservation day.

Ferro cement is use to create a construction skeleton using cement motor, metal rod & mesh. 

Correct option is A) have applied

As a Manager, Informal Communication is helpful to know the reaction of your subordinate.

SYMAP mapping program was developed by the Harvard School of Design.

Correct option is B) have you been made

C. 1m

1m is the spatial resolution of IKONOS.

Tone refers to the relative brightness of objects in an image.

It is a graph showing the number of pixels in an image at each different intensity value.

Eg. 256 different possible intensities for an eight-bit grayscale image.

Histogram equalization: 

• It is the technique by which the dynamic range of the DN values of an image is increased.
• It assigns the intensity values of pixels in the input image to show a uniform distribution of intensities. 
• It improves contrast and obtains a uniform histogram

Histogram Stretching:

• It is a simple image enhancement technique that improves the contrast image. 
• It uses methods like linear and nonlinear contrast stretching for image enhancement.

Correct option: C. Raster

TIN Spatial analysis tool uses Triangle by Triangle method.

b. Informal Communication

As a Manager Informal Communication is helpful to know the reaction of your subordinate.

Correct option: D. Legality

D. Economic data

Economic data is not an input of a hazard map.

A process to categorize all pixels in a digital image into one or several land cover classes or themes. It uses the spectral information represented by the digital numbers in one or more spectral bands and classify each individual pixel based on this spectral information(DN). Based on DN values we can create the classes like vegetation, water body, barren land, build up area etc. 

Differentiate between Supervised and unsupervised classification (three distinctions)

A. Resampling

Resampling method is used to remove noise from images.

Data security, integrity, storage, retrieval and maintenance.

The shift in location and change in shape of the features is called as Locational errors.

1. The way skeleton of bones supports other delicate organs in the body of living organisms, RCC (Reinforced Cement Concrete) is used to strengthen the foundation of the building. 

2. Cement concrete possesses good compressive strength; however, its tensile strength. Therefore, iron are placed along with concrete wherever tension is anticipated. 

3. It is called as R.C.C (Reinforced Cement Concrete). Due to higher amount of strength in R.C.C. columns, they are durable and construction becomes long lasting. 

4. It is economical and it is easy to construct. 

5. It is useful for heavy load bearing structures.

C. K Means

K Means is not an algorithm of supervised classification.

C. Mobile GIS

Mobile GIS can create, edit and uses GIS maps in the field.

Correct option: b. Rain gauge

Protractor is used to meet or align a specific angle at a desired location in a drawing. 

Protractor is use to draw a specific angle at a desired location in a drawing.
