Sequence of GIS Activities

There are three basic types of scanners.

The properties of a spatial entity in GIS are defined by non-spatial data which is called _____(digital/attribute) data.

The operation carried in bringing two information sets together and storing them as another file is called _____(Hierarchical/Exact/Fuzzy) matching.

The kind of analysis used to study the impact of point sources of air, noise or water pollution on human health is called _____(Buffer/Proximity) analysis.

The use of digitisers and the scanners greatly reduce the time and labour involved in writing down coordinates.

In GIS, Proximity analysis is carried under buffer operations.

The hallmark of GIS is _____ analysis operations.

Hierarchical Matching is the method involved in the spatial analysis of GIS acitivities.

The spatial data captured into a GIS require verification for the error identification and corrections to ensure the data accuracy

_____ data input is one of the sequences of GIS activities.(Spatial/Non-spatial)

What are the advantages of using vector data format over raster data format?
