The OGP P1/90 Post Plot Positioning Data Reader/Writer allows FME to access the exchange of data from a single survey that has been stored as an ASCII encoded P1/90 file.
Overview
The P190 Reader module produces FME features for all data records found in a .p190 file. It also produces a single FME feature for all the header records. It supports conventional and non-conventional 2-D offshore surveys and conventional 2-D onshore surveys. Non-conventional offshore surveys are not supported at this time.
Writing of P1/90 files is handled by the P190 Writer module. The P1/90 writer creates and writes point feature data to P1/90 files into the specified folder. It supports conventional and non-conventional 2-D offshore surveys and conventional 2-D onshore surveys.
Reader Overview
Each data record corresponds to a FME feature. The information in each record will appear as attributes on the corresponding FME feature type. Coordinates found in the record will also be used to determine FME feature geometry.
Each header record will be aggregated into a single FME feature type. The information in each record will appear as attributes on the corresponding FME feature type. The header information is additionally investigated for datum, projection, and unit information and creates a custom coordinate system if no coordinate system is specified in FME.
Writer Overview
The P1/90 writer creates and writes point feature data to P1/90 files into the folder specified by the Dataset parameter. Existing files with the same name specified are overwritten with new feature data. It supports conventional and non-conventional 2-D offshore surveys and conventional 2-D onshore surveys.
The required header record types, 0100 to 0800 and 1200 to 2000 inclusive, will be populated using respective attributes. The coordinate system must be specified on the writer.
