Reader Overview

FME considers a single Garmin GPI file to be a dataset.

Each dataset consists of features with point geometry, and uses the LL84 coordinate system.

Writer Overview

The dataset is the destination filename. The feature type of each dataset is the filename.

The Garmin GPI writer will only write data in decimal degrees (WGS84 datum). All features passed to the writer will be reprojected to LL84 (EPSG:4326) if this functionality is licensed. Features with no coordinate system are assumed to be in LL84.

The Garmin GPI writer uses a fixed schema.

Note: Unicode attribute writing is not supported. Accented characters are replaced with unaccented equivalents. Other Unicode characters are replaced with “$”.
