Data Formats
In ArcView, the spatial data for themes falls into two major categories: feature data sources and image data sources.

 


data format
[data structures] The structure used to store a computer file or record.

RASTER DATA FORMATS
Raster data models incorporate the use of a grid-cell data structure where the geographic area is divided into cells identified by row and column. This data structure is commonly called raster.

A shapefile is a vector data format for storing the location, shape, and attributes of geographic features. A shapefile is stored in a set of related files and contains one feature class.

DATA FORMAT
A specification which defines how data is structured in a file and which determines such aspects as the sequence of data items, their length, and necessary HEADER data.

Data Formats and Different Standards The major hurdle in coming up with a standard benchmark is the various data formats used by the different vendors of GIS. There are efforts to unify the data representation and to come up with a common data model.

To convert spatial data, a data format should be used that embeds co-ordinate and projection information. Vector data formats, however, often don't include projection information.

During 1980's, the change in data format and computer environment was exploited. Spatial database management systems were developed that linked computer mapping capabilities with traditional database management capabilities.
