Quake Land Zone (OpenData)

This entity describes Canterbury Earthquake Recovery Authoritys (CERA) broad classification (eg, Red Zone, Orange Zone, etc) of earthquake land damage within Christchurch, indicating what stage the land assessment process is at and if concluded, whether or not it will be possible to rebuild on the land. Areas currently zoned Orange will progressively be reclassified as either Red or Green. Areas zoned Green are further classified into technical categories - refer QuakeFoundationDesign entity. Data Source is Tonkin & Taylor who supply updates as a WFS feed on behalf of CERA. The data is 'maintained' inhouse via a bulk archive of existing records from QuakeLandZone then running of an app to repopulate with the latest CERA update. This feature will be intersected with stRatingUnitCentroid for the purposes of Spatial Significance Comment generation and QuakeLandZone records MUST therefore be disassociated BEFORE being archived. It is spatially abstracted to an area. Entity type Concept.
