GridInQuestReprojector

Reprojects feature coordinates from one coordinate system to another using the Grid InQuest reprojection library. This library allows you to use the GridInQuestReprojector to transform coordinates between ETRS89 (WGS84) and the national coordinate systems of Great Britain, Northern Ireland and the Republic of Ireland.

This transformer always reprojects from the source coordinate system to the destination coordinate system, tagging the features with the destination coordinate system on output. Any coordinate system set on the input features is ignored.

Parameters

Usage Notes

The GridInQuestReprojector is supported on the 32-bit Windows edition of FME only. The GridInQuestIIReprojector is supported on both 32-bit and 64-bit Windows edition of FME.

This transformer is unaffected by raster band and palette selection.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
