Question

Multipart features are used to represent multiple geographic objects that represent parts of the same entity. True/False?

Select the following statements that are true about a GIS database: Thematic layers organize spatial and attribute data Data from different thematic layers are combined through analysis Real world data is represented as separate thematic layers Different types of thematic data can be combined in one layer of a GIS database.

Topological data layers often ease data processing and maintain spatial integrity, at the cost of more complex data structures. True/False?

Explanation / Answer

1: Multipart features are used to represent multiple geographic objects that represent parts of the same entity.
Answer : True
       In GIS multipart feature are used to reprsent the multipl geographic object for example amultipart feature has several lines or polygons within it but references the same entity.

2 : Thematic layers organize spatial and attribute data
Data from different thematic layers are combined through analysis
Real world data is represented as separate thematic layers
Different types of thematic data can be combined in one layer of a GIS database.
           All the above satement are true about the GIS data base. In GIS data base different types of thematic layes are used like polygon, line, point and it can be combined in one layer. Differet thematic layes are used to represent the different real world features like roads, areas. point features. and different thematic layes are used in GIS for for seperate real world data so it could be easy to undestand and easy handle.

3: Topological data layers often ease data processing and maintain spatial integrity, at the cost of more complex data structures.
Answer: True
       a GIS stores the data from which we can draw a desired view to suit a particular purpose known as geographic data. There are two types of data in GIS; spatial data and non-spatial data. Non-spatial data include information about the features. Non-spatial or attribute data is that qualifies the spatial data
