The suffixes listed are prefixed by the current <ReaderKeyword> in a mapping file. Unless otherwise specified, the <ReaderKeyword> for the ArcGIS Layer reader is the same as the <ReaderType>.
DATASET
A single Esri layer/feature class from which data is to be read. The value for an Esri layer is simply the layer file. The value for a feature class is the Esri path to the file/database containing the feature class plus the name of the feature class. The Esri path is displayed in the Location toolbar within Esri ArcCatalog.
The FME dataset selector has been enhanced for the ArcGIS Layer reader to use Esri’s layer/feature class picker. Using this selector will greatly simplify the process of selecting a dataset.
Required/Optional: Required
Esri Layer Example:
ARCGIS_LAYER_DATASET “C:\data\runways.lyr”
Feature Class within a Personal Geodatabase Example:
ARCGIS_LAYER_DATASET “C:\data\airport.mdb\runways”
Feature Class within an Enterprise Geodatabase Example:
ARCGIS_LAYER_DATASET “Database Connections\esri92.sde\JOE.runways”
FME Feature Class within a MIF/MID file Example (requires ArcGIS to be extended by FME):
ARCGIS_LAYER_DATASET “C:\data\mif\usa.mif\usa Line”
Workspace Parameter: Esri ArcGIS Layer
DEF
Describes feature classes. Normally these lines are automatically generated within a mapping file/workspace using FME.
Required/Optional: Optional
Example:
ARCGIS_LAYER_DEF Parcels \
geodb_type geodb_polygon \
OBJECTID_1 integer \
PROPERTY_I double \
LANDUSE_CO char(3) \
ZONING char(6) \
PARCEL_ID integer \
Res smallint \
ZONING_S char(4) \
Shape_Length double \
Shape_Area double
SEARCH_ENVELOPE
Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that interact with the bounding box are returned.
If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.
Mapping File Syntax
<ReaderKeyword>_SEARCH_ENVELOPE <minX> <minY> <maxX> <maxY>
Note: If all four coordinates of the search envelope are specified as zero, the search envelope will be disabled.
Required/Optional
Optional
Workbench Parameter
Minimum X, Minimum Y, Maximum X, Maximum Y
SEARCH_ENVELOPE_COORDINATE_SYSTEM
This directive specifies the coordinate system of the search envelope if it is different than the coordinate system of the data.
The COORDINATE_SYSTEM directive, which specifies the coordinate system associated with the data to be read, must always be set if the SEARCH_ENVELOPE_COORDINATE_SYSTEM directive is set.
If this directive is set, the minimum and maximum points of the search envelope are reprojected from the SEARCH_ENVELOPE_COORDINATE_SYSTEM to the reader COORDINATE_SYSTEM prior to applying the envelope.
Required/Optional
Optional
Mapping File Syntax
<ReaderKeyword>_SEARCH_ENVELOPE_COORDINATE_SYSTEM <coordinate system>
Workbench Parameter
Search Envelope Coordinate System
CLIP_TO_ENVELOPE
This directive specifies whether or not FME should clip features to the envelope specified in the SEARCH_ENVELOPE directive.
Values
YES | NO (default)
Mapping File Syntax
<ReaderKeyword>_CLIP_TO_ENVELOPE [yes | no]
Workbench Parameter
Clip To Envelope
EXPOSED_ATTRS
This directive allows the selection of format attributes to be explicitly added to the reader feature type.
This is similar to exposing format attributes on a reader feature type once it has been generated; however, it is even more powerful because it enables schema-driven applications other than Workbench to access and leverage these attributes as if they were explicitly on the schema as user attributes.
The result of picking a list of attributes is a comma-separated list of attribute names and types that will be added to the schema features. Currently all reader feature types will receive the same set of additional schema attributes for a given instance of the reader.
Required/Optional
Optional
Mapping File Syntax
Not applicable.
While it is possible for FME Objects applications to invoke this directive, the required format is not documented.
This directive is intended for use in our GUI applications (for example, Workbench) only.
Workbench Parameter
Additional Attributes to Expose
