Data Profile

NGII Standard

Metadata Harvesting

•  NGII has selected 5 data products and then developed the standard profiles which are based in ISO 19100 series

•  Metadata, Data quality, Data specification

• metadata, data quality and data specification for aerial photograph, geospatial information, land survey database, orthoimage, unified control point

• XML schema implementation of metadata, data quality for 4 data products

Description Outcome

01

02

03

•  NGII standards(13) are established about metadata, data quality and data specification for 5 data products

• metadata, data quality and data specification for aerial photograph, geospatial information, orthoimage, unified control point

• data specification for land survey database

•  metadata harvesting has carried out for extracting effectively from legacy databases

• aerial photograph, geospatial information, orthoimage, unified control point

• code & enumeration • variable type & unit

System Enhancing

04 •  The profile results are applied in NGII information systems

•  The CSW have been implemented in accordance with the rules established by OGC and ISO 19115 series

• aerial photograph, geospatial information, orthoimage, unified control point

• Data management and service systems
