OGP P1/90 Post Plot Positioning Data Reader Parameters
Output Feature Parameters
Specifies the feature type that FME will create and the type of data records produced:
- Points: The data records are read as is, one record per one point, and no attribute data is lost.
- Lines: The point geometry data will be aggregated on line name, producing one feature per unique line name.
- Both: The previous feature types will both be created and both types will be output.
Specifies which measure values will be added to the output geometry:
- No measures: No measure values will be added to the geometry.
- Shotpoint number: The measure value will be set to the shotpoint number value on the data records.
- Depth value (z-coords): The z-coordinates will be duplicated on the geometry as measure values.
Use 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 intersect with the bounding box are returned.
If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.
When selected, this parameter removes any portions of imported features being read that are outside the Search Envelope.
The example below illustrates the results of the Search Envelope when Clip to Search Envelope is not selected (set to No) and when it is selected (set to Yes).
- No: Any features that cross the search envelope boundary will be read, including the portion that lies outside of the boundary.
- Yes: Any features that cross the search envelope boundary will be clipped at the boundary, and only the portion that lies inside the boundary will be read. The underlying function for the Clip to Search Envelope function is an intersection; however, when Clip to Search Envelope is selected, a clipping operation is also performed in addition to the intersection.
