The directives listed below are processed by the RDB reader.
The suffixes shown are prefixed by the current <ReaderKeyword> in a mapping file. By default, the <ReaderKeyword> for the RDB reader is RDB.
DATASET
The value for this directive is the index file within the RIEGL database to be read.
Required/Optional
Required
Mapping File Syntax
RDB_DATASET C:\data\file.rdx
Workbench Parameter
Source RDB File(s)
GROUP_BY_SCAN
This directive indicates whether the feature type will be the scan name.
Required/Optional
Optional
Values
YES | NO (default)
Mapping File Syntax
<ReaderKeyword>_GROUP_BY_SCAN [yes | no]
Workbench Parameter
Group By Scan
SCANNER_INSTRUMENT_TYPE
The value for this directive is the type of scanner instrument used to retrieve the RDB data. This is used to determine whether the data contains reflectance. If so, the intensity component will contain reflectance values; if not, it will contain amplitude values.
Required/Optional
Optional
Values
V-Line (default) | Z-Line | Q-Line | Other
Mapping File Syntax
<ReaderKeyword>_SCANNER_INSTRUMENT_TYPE [V-Line | Z-Line | Q-Line | Other]
Workbench Parameter
Scanner Instrument Type
DAY_OF_WEEK
Specifies the day of week (Sunday=0 to Saturday=6) on which the scan was taken. If the timestamp values in the file represent dayseconds, an appropriate offset will be applied to all the timestamps (e.g. for Monday, all timestamps will be offset by 86400). If the timestamp values in the file represent weekseconds, this directive is ignored.
Required/Optional
Optional
Values
0 to 6
Mapping File Syntax
<ReaderKeyword>_SCANNER_INSTRUMENT_TYPE [V-Line | Z-Line | Q-Line | Other]
Workbench Parameter
Scan Day of Week
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>
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
