Geographic Information System 4th Topic

What is a GIS Database…?

• Data are facts that are collected, recorded, stored and processed by information systems which contain geographic spatial information

• Data are facts that are combined, Replaced, Edited and processed by information systems which contain geographic spatial information

• Geodata are facts that are collected, recorded, stored and processed by information systems which contain geographic Special information

• GeoData are facts that are combined, Replaced, Edited and processed by information systems which contain geographic Special information

These are correct GIS Data Source:

• Remote sensing data,

  Field data,

  Map / map data,

  Statistics,

  GPS data,

•Data resulting from statistical records in the form of tables, reports, field surveys, and population censuses ... etc.

•Obtained from private institutions or official government agencies, such as the Central Bureau of Statistics (BPS)

•Statistical data is secondary data that has undergone further processing in statistical books.

• Field data (terrestrial)

• Map Data(map)

• Statistic data

• Remote sensing data (remote sensing)

Remote sensing data (remote sensing)

this type of data is correct if .....

• Data obtained directly through observations in the field

• Obtained from private institutions or official government agencies, such as the Central Bureau of Statistics (BPS)

• Data recorded on paper or film

  Example:

  •geological map

  •soil type map… etc

• Data in the form of imagery, aerial photographs or non-photographs… etc

What are spatial databases in GIS?

• Spatial databases provide a foundation for accessing, micro-managing, and creating your spatial data workflow.

• Spatial databases provide a strong foundation for accessing, storing, and managing your spatial data workflow.

• Spatial databases provide a heavy foundation for deleting, storing, and managing your spatial data workflow.

• Spatial databases enhance a strong correlation for accessing, storing, and managing your spatial GIS .

what do you know about this?

• a basic table which explain about position enhancement in GIS

• a table which provide relative position of an object which can be replaced depends on the purpose

• it's an attribute table in GIS

• it's an essential part of GIS to provide hierarchy

Rows in an attribute can have relationships with spatial features. There are three types of relationships:

• 1. One-to-one relationship

  2. One-to-many relationship

  3. Many-to-many relationship

• 1. 1-to-1 relationship

  2. 1-to-infinite relationship

  3. Many-to-many relationship

• 1. One-to-one relationship

  2. one-to-infinite relationship

  3. Many-to-many relationship

• 1. One-to-one relationship

  2. One-to-many relationship

  3. infinite-to-infinite relationship

This is an example of an RDBMS.

RDBMS is a relational storage concept for data. A relational database contains tables that hold records. Each record holds fields containing data for that record.

• TRUE

• FALSE

• NOT DEFINED

GIS data helps us understand and meet global challenges. As GIS technology rapidly advances, there are various innovative applications in the planning sector. GIS tools can be used to integrate geographic intelligence into planning processes, and have the potential to change how we think and behave.
