Types of Attribute Data Attribute data can be store as one of five different field types in a table or database: character, integer, floating, date, and BLOB. The character property (or string) is for text based values such as the name of a street or descriptive values such as the condition of a street.
What is the maximum precision for a short integer field?
5
However, short integer columns can only store values within the range of -32,768 to 32,767. Therefore, you cannot store a value greater than 32,767 or less than -32,768 in a short integer field, even if you set the precision to 5.
What is the largest character value in Java?
What is a Java char? The char data type is a single 16-bit Unicode character. It has a minimum value of ” (or 0) and a maximum value of ‘ffff’ (or 65,535 inclusive).
How many characters are in a shapefile field name?
So the ten-character limit imposed by UTF-8 for the length of a shapefile field name is actually ten bytes. For example, since Japanese characters require three bytes per character, this reduces the limit to three characters for a shapefile field name. The other issue is text fields.
What is the maximum width of a shapefile?
The shapefile maximum field width is 254. It is a limitation of the dBase format. File geodatabase text fields are unlimited in length (2^31-1) and enterprise geodatabases are limited by their underlying RDBMS for VARCHAR and NVARCHAR width. The only way to work around the dBase width limitation is to not use shapefiles.
Why are shapefile field names truncated in UTF-8?
This problem occurs because the string length for shapefiles are measured in bytes, not characters. So the ten-character limit imposed by UTF-8 for the length of a shapefile field name is actually ten bytes.
How many polygons can be stored in a shapefile?
Geometry limitations. There is a 2 GB size limit for any shapefile component file, which translates to a maximum of roughly 70 million point features. The actual number of line or polygon features you can store in a shapefile depends on the number of vertices in each line or polygon (a vertex is equivalent to a point).
