The IDRISI Vector Format Reader and Writer modules allow FME to read and write IDRISI vector files. IDRISI files use a published binary format. The IDRISI data and the documentation file structure are described in the IDRISI Guide to GIS and Image Processing, Volume 1.
Overview
IDRISI is a geographic information and image processing software system that is widely used by universities worldwide. It is a two-dimensional (2D) system which allows user-defined attributes stored in an Access database to be linked to its data file.
IDRISI features contain a feature geometry and an id number. An IDRISI file consists of at least two physical files, having the following filename extensions:
|
Filename Extension |
Contents |
|
.vct |
Vector data file |
|
.vdc |
Vector documentation file |
If an Access database is available, the following files should also be available:
|
Filename Extension |
Contents |
|
.vlx |
Vector link information file |
|
.mdb, .accdb |
Access database file |
|
.adc |
Attribute documentation file |
These extensions are added to the basename of the IDRISI file.
The IDRISI reader and writer support the storage of point, line, area (polygon), and text geometric data in the .vct files.
The FME considers an IDRISI dataset to be a collection of IDRISI files in a single folder.
