ArcGIS Data Types

ArcGIS Field Data Types

Tutorial Contents

File Geodatabase data types are the same as ArcGIS data types.

The following table lists for file and personal Geodatabases’s data types, their ranges, and storage requirements.

Data type	Storable range	Size (Bytes)	Applications
Short integer	-32,768 to 32,767	2	Numeric values without fractional values within specific range; coded values
Long integer	-2,147,483,648 to 2,147,483,647	4	Numeric values without fractional values within specific range
Float (single-precision floating-point number)	approximately -3.4E38 to 1.2E38	4	Numeric values with fractional values within specific range
Double (double-precision floating-point number)	approximately -2.2E308 to 1.8E308	8	Numeric values with fractional values within specific range

Data types and their possible precision and scale values you can set in ArcGIS Desktop.

Data type	Precision (maximum field length)	Scale (maximum number of decimal places)
Short integer*	1–5 (Oracle)	0
Long integer**	6–9 (Db2 and Informix)6–10 (Oracle)	0
Float	1–6	1–6
Double	7+	0+

Number ranges and store them in a database or desktop Geodatabase

Range	Data type	Precision (field length)	Scale (decimal places)
0 to 99	Short integer	2	0
-99 to 99*	Short integer	3	0
0 to 32,767*	Short integer	5	0
32,768 to 99,999	Long integer	5	0
0.001 to 0.999	Float	4	3
1,000.00 to 9,999.99	Float	6	2
-123,456.78 to 0*	Double	9	2
0 to 1,234.56789	Double	9	5

You create a Feature class or table in ArcGIS, there are 11 different data types available for each column.
