fxshape: ESRI Shape Files

A file-based interface, converting to nodes, polylines and polygons with or without column attributes.

Shape files have no inherent symbology, so the default symbology will be assigned to all graphic primitives.

Nothing is known about the projection or units of measure of Shape data. These must be set by the client if required. Both 2-D and 3-D shape data is supported.

Extensions to Standard Commands

query_tables

query_tables <client_string_array>

Returns the names of all shape files in the current directory and sub-directories. This list is also selectable by the following command:

iselect * from fxtables

select

select {* | <column>, … } from <file> where <conditions>

Selects the shape file from which all data is to be fetched. Selection can be on all, none or selected column attributes.

Additional Commands

point_column

point_column <column_name>

When retrieving point data, the default action is to create marker (node) graphic primitives. This command specifies a column from the non-graphic data, whose text values are to be used to create text primitives instead of marker primitives.

point_text

point_text <text>

When retrieving point data, the default action is to create marker (node) graphic primitives. This command specifies a constant text value to be used to create text primitives instead of marker primitives.
