DESCRIPTION

This free tool converts National Geospatial-Intelligence Agency (NGA) feature data in Vector Product Format (VPF) to SEDRIS Transmittal Format (STF).

RELEASE INFORMATION

This tool is SEDRIS 3.1.2 compliant.

FEATURES

• Reads a transmittal definition file, where the user specifies:
• the absolute path to a VPF database directory,
• the name of a particular data library subdirectory within the specified VPF database that is to be the source of the transmittal,
• the names of one or more coverages within the specified VPF library that are to be included in the transmittal,
• the values of various required transmittal-level metadata elements, such as the Citation, Access, and Point of Contact, that cannot be derived from the contents of the VPF database,
• the location of the vpf error file, and
• optionally, the area of interest.
• Populates as much required transmittal-level metadata as possible with values from the VPF database and library header tables.
• Creates a separate Classification Related Features object for each selected VPF coverage.
• Processes multiple tiles within a VPF coverage into corresponding Perimeter Related Feature Topology objects.
• If an area of interest is specified, only those tiles that are at least partially within that area of interest are processed.
• Creates a separate Union of Features object containing all features with each unique FACC feature code within each selected coverage.
• Processes all VPF point, line, and area features within the selected coverages, including compound features (i.e., features that consist of multiple primitives).
• Breaks non-sequential compound line features into multiple SEDRIS Linear Features all contained within a single Union of Features object.
• Translates FACC feature codes to corresponding EDCS classification codes.
• Assigns EDCS classification codes to non-FACC features (e.g., Data Quality features) using look-up tables.
• Creates Property Value objects for each feature attribute.
• Translates FACC attribute codes to corresponding EDCS attribute codes.
• Assigns EDCS attribute codes to non-FACC attributes using look-up tables.
• Creates all topological relationships supported by the source data.
• Retains VPF coverage and feature class names as keywords.

LIMITATIONS

• Only processes features contained in a single VPF library.
• Does not process VPF text features.
• Cannot process multiple-valued attributes contained in Related Attribute Tables (RATs); only the first attribute value is processed.
• Does not support the translation of VPF cross-tile topology.
• Operation can be disrupted by serious errors in the structure and organization of the VPF data, such as critical files that are missing or corrupted.
• Errors in the VPF source data are listed in a text file (vpf errors).
• The SEDRIS Syntax Checker may complain about invalid units when the default EUC_UNITLESS are assigned, the mapping type is EDCS_MAPPING_TYP_CHANGE_TO_METADATA, and the unit equivalency class does not include EUC_UNITLESS.
