Which of the following statements are true?

Both ‘1’ & ‘2’ are true

Natural phenomena are usually fields

Man-made phenomena are usually objects

Which of the following is true about ‘Discrete fields’

Discrete fields divide the study space in mutually exclusive, bounded parts, with all locations in one part having the same field

value ‘Land classification’ is an example of discrete fields

Discrete fields make use of ‘bounded’ features

Which of the following is true about ‘Nominal Data Values’

They are values that provide a name or identifier so that we can discriminate between different values

True computations cannot be done with these values

When the values assigned are sorted according to some set of non-overlapping categories, they are called ‘categorical data’

Which of the following is true about ‘Ordinal Data Values’

They are date values that can be put in some natural sequence but that do not allow any other type of computation

An example of Ordinal data value is classifying household income as ‘low’, ‘average’ or ‘high’

Which of the following is true about ‘Internal Data Values’

They are quantities, in that they allow simple forms of computation like addition & subtraction

They do not support multiplication or division

Centigrade temperatures are internal data values

Which of the following is true about ‘ Ratio Data Values’

They allow most, if not all, forms of arithmetic computation

Multiplication & division of values are possible

Continuous fields can have ratio data values

Which of the following is true

Nominal & categorical data values are referred to as ‘qualitative data’

Internal & Ratio data is known as ‘quantitative data’

Ordinal data refers to a ranking scheme or some kind of hierarchical phenomena

The fundamental principle which refers to the fact that locations that are closer together are more likely to have similar values than locations that are far apart, is commonly referred to as

Tobler’s first low of Geography

Kepler’s first law of Geography

Anthony’s first law of Geography

Thompson’s first law of Geography

Which of the following is true

Tessellations partition the study space into cells & assign a value to each cell

A raster is a regular tessellation with square cells (by far the most commonly used)

Which of the following is true about ‘Delaunay Triangulation’

The triangles are as equilateral s they can be

For each triangle, the circumcircle through its anchor points does not contain any other anchor point

Which of the following statements are true about the ‘ temporal dimension’

Time can be measured along a ‘discrete’ or ‘continuous’ scale.

Valid time (or world time) is the time when an event really happened, or a string of events took place.

Time can be considered to be ‘linear’ extending from past to the present (‘now’), & into the future

When measuring time, we speak of granularity as the precision of a time value in a GIS or database.

Which of the following is true?

‘Fields’ are geographic phenomena that occur everywhere in the study area

‘Objects’ are geographic phenomena that occur ‘sparsely’ over the study area

Fields can be continuous or discrete

Objects can be classified based on location, shape, size & orientation

What are the various reasons for which DBMS is used

A DBMS supports the storage and manipulation of very large data sets

A DBMS can be instructed to guard over data correctness

A DBMS supports the concurrent use of the same data set by many users

Which of the following is true about DBMS

A DBMS provides a high-level, ‘declaration query language’

A DBMS supports the use of a ‘data model’

A DBMS includes ‘data backup’ and ‘recovery’ functions to ensure data availability at all times

A DBMS allows the control of ‘data redundancy’

A ‘data model’ is a language that allows the definition of

The ‘structures’ that will be used to store the base data

The ‘integrity constraints’ that the stored data has to obey at all moments in time

The ‘computer programs’ used to manipulate the data

Which of the following statements is true in connection with a ‘tuple’

‘1’ , ‘2’ & ‘3’ are true

The set of tuples in a relation at some point in time is called the ‘relational instance’ at that moment

This tuple set is always finite

It is possible to count how many tuples are there

Only ‘1’ & ‘2’ are true

GIS uses the information from which of the following sources?

Non- spatial information system

Which of the following doesn’t determine the capability of GIS?

Representing cartographic feature

Which of the following acts a benefit of GIS?

Presence of data retrieval service
