Mapping File Syntax
ESRIASCIIGRID_DATASET “C:\DATA\ESRIASCII\portland.grd”
Workbench Parameter
Source Esri ASCII Grid File(s)
GROUP_BY_DATASET
When the value is set to No, the only feature type this reader will use is the reader type name.
When the value is set to Yes, the feature type of each dataset is the filename (without the path or the extension) of the dataset.

Values
YES | NO (default)

GROUP_BY_DATASET “Yes”
Workbench Parameter
Feature Type Name(s)
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
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.
TheCOORDINATE_SYSTEMdirective, which specifies the coordinate system associated with the data to be read, must always be set if theSEARCH_ENVELOPE_COORDINATE_SYSTEMdirective is set.
If this directive is set, the minimum and maximum points of the search envelope are reprojected from theSEARCH_ENVELOPE_COORDINATE_SYSTEMto the readerCOORDINATE_SYSTEMprior to applying the envelope.

CLIP_TO_ENVELOPE
This directive specifies whether or not FME should clip features to the envelope specified in theSEARCH_ENVELOPEdirective.
Values
YES | NO (default)
