Working with SHP Data
The standalone ESRI SHP file format supports GIS data using the following
file types:
■ SHP (shape geometry)
■ SHX (shape index)
■ PRJ (projection information)
■ CPG (code page files)
■ IDX (spatial index)
■ DBF (shape attributes in dBASE format)
You must have either a SHP or DBF file present to connect to data or work
with schemas (page 2073). Otherwise, these files are optional. If they do not
exist initially, the system creates files with empty records.
NOTE This functionality affects geospatial feature data only. For information about
linking records in an external database to objects in a drawing, see
Overview of
Linking Database Records to Objects
(page 522).
Characteristics of the SHP File Format
The Schema Editor treats each SHP file, and its associated DBF file, as a
feature
class
(page 2063) with a single geometry property (page 2071) and, optionally, data
attribute properties. The SHP file format supports a single writer at any time,
but can have multiple readers.
SHP files can include only one geometry type per file, but you can store and
copy multiple SHP files in a folder. You can use a configuration file to support
multiple schemas when you establish your connection to a folder containing
SHP files.
