Arc/Info E00 (ASCII) Coverage¶
Driver short name
Driver built-in by default
This driver is built-in by default
Arc/Info E00 Coverages (eg. Arc/Info V7 and earlier) are supported by OGR for read access.
The label, arc, polygon, centroid, region and text sections of a coverage are all supported as layers. Attributes from INFO are appended to labels, arcs, polygons or region where appropriate. When available the projection information is read and translated. Polygon geometries are collected for polygon and region layers from the composing arcs.
Text sections are represented as point layers. Display height is preserved in the HEIGHT attribute field; however, other information about text orientation is discarded.
Info tables associated with a coverage, but not specifically named to be attached to one of the existing geometric layers is currently not accessible through OGR. Note that info tables are stored in an ‘info’ directory at the same level as the coverage directory. If this is inaccessible or corrupt no info attributes will be appended to coverage layers, but the geometry should still be accessible.
The layers are named as follows:
A label layer (polygon labels, or free standing points) is named LAB if present.
A centroid layer (polygon centroids) is named CNT if present.
An arc (line) layer is named ARC if present.
A polygon layer is named “PAL” if present.
A text section is named according to the section subclass.
A region subclass is named according to the subclass name.
Random (by FID) reads of arcs, and polygons is supported it may not be supported for other feature types. Random access to E00 files is generally slow.
This driver supports georeferencing
This driver supports virtual I/O operations (/vsimem/, etc.)
