Web services supported on Koordinates
WFS Web Services
Koordinates supports WFS 1.x and WFS 2.x OGC web services. These web services are commonly used as data interchange standards in the GIS sector, including for geoprocessing tasks and desktop GIS data access. These web services allow for users to extract vector and tabular data layers from a Koordinates site.
Koordinates provides support for a WFS Changeset Service which gives access via WFS 1.x and WFS 2.x to data updates between dates for a particular ‘versioned’ vector layer or tabular data layer. This allows applications to update local copies of data layers on an ongoing incremental basis, and is particular useful for users of data layers that are regularly updated.
OGC Catalogue Service for Web
Koordinates supports the OGC Catalogue Service for Web (CSW) web service. This is a common open standard for federating XML metadata information between different data catalogues.
XYZ and OGC Web Map Tiling Services (WMTS)
Koordinates provides XYZ and OGC Web Map Tiling Services (WMTS). Tile services can be administered by Data Administrators and published in NZTM and Web Mercator for compatibility with common New Zealand professional GIS uses and Google Maps-style interactive maps.
For vector data layers, and sets of vector data layers, administrators can use the web interface to define one or more complex cartographic styles. These can be published as separate tile services for use in external desktop applications, websites and mobile applications.
