GIS Metadata
Metadata are structured facts that describe information, or information services. Metadata facilitates many things beyond enabling information discovery and access; it also informs about the appropriate use of products and services.
The recently launched AAM Metadata application (developed by the AAM GIS and Software Development teams) produces metadata records which comply with the International Organization for Standardization (ISO) schema for describing geographic information and services (ISO 19115, ISO 19115-2 and ISO 19139). The details recorded pertaining to digital geographic data comprise:
| - Identification - Extent - Quality - Spatial and temporal schema - Spatial reference |
- Limitations of use - Distribution - Properties of measuring equipment used to acquire data - Geometry of the measuring process employed by the equipment - Production processes used to digitise the raw data |
ISO compliant metadata records are created for all spatial datasets produced by AAM including 3D models, ortho photography, satellite imagery, digital elevation models and stereo vector mapping in a multitude of formats including:
| - ASCII XYZ - ESRI suite - LAS - MapInfo suite - ECW - GeoTIFF/TIFF - JPG/JP2 - MrSID |
- 3DS - KML - GML - VRML - DXF/DWG - DGN - Custom formats |
The metadata records are catalogued in a database and supplied with data to provide a full description of each data set. To enable easy searches and display of metadata in support of all spatial data sets, the metadata tool has an accompanying custom web interface available.
