Description: QEII CQEII CovPolys - - 1/2QEII Covenant Polygon Data DefinitionIntroductionThe digital layer of QEII covenant boundaries has been compiled from various sources around thecountry, including regional and district councils, DOC conservancies, surveyors and LandOnline.Funding from TFBIS in 2005 enabled QEII to sub-contract the digital capture of covenant boundariesfrom survey plans for the remaining parts of the country. Since 2005, new covenant boundaries aresupplied directly to QEII by the surveyors who produce the survey plans or are downloaded fromLandOnline. It should be noted that the digital boundaries of the covenants are a graphicrepresentation only and should not be taken as the definitive covenant boundary.Status – Completeness and QualityAs at 13 February 2015, the data are 100% complete (3980 registered and formalised covenants withpolygons). The quality of the data has been assessed by comparing the registered area of eachcovenant (in hectares) with the geometric area as calculated in the GIS. Currently 95.7% of thepolygons are within +/- 10% of the registered area (QualCode = 1). The remaining 4.3% have to beverified and either require re-digitising or some further amendment. We are working our way throughprocessing these to improve the quality. 594 polygons have not yet been verified against a survey planor photodiagram. Please note that the quality code described above is no reflection of the positionalaccuracy.UpdatesEach year, approximately 200 new covenants are approved by the QEII Board, but each may take, onaverage, two years to complete the process to registration. At current rates of funding and processing,QEII is able to register about 40-50 new covenants each quarter. In addition, there are a number ofchanges to existing covenants as a result of sub-divisions, changes of ownership, variations and soon.An update of the digital covenant polygon layer will therefore be issued every three to four months toreflect the changes to the national dataset.AttributesThe covenant polygons have the following attributes from the covenants database:Attribute Format DescriptionCovNumber Text 12 Unique file reference number for the covenant, e.g. 5-02-171. NB. Somecovenants are in the process of being re-numbered to simplify the numberingsystem.All covenants start with a 5; QEII property numbers start with a P, eg. P 21.The second part of the covenant number defines the Land Registry District,eg. 02 = Northland. Covenants are numbered sequentially within a LandRegistry District.CreatedBy Text 35 6 main categories defining how the polygon was derived:- Digital file from surveyor – Captured from survey plan (as dxf, dwg or.shp)- Digitised from plan – Unverified – Digitised from plan or exact methodunknown and not yet verified- Digitised from plan – Verified – Digitised from scanned plan orphotodiagram and verified- Captured from CRS parcels – Captured from LINZ Data Service or LINZLandOnline- DP Plan Distance and Bearing – Polygon constructed from distance andbearing information on deposited plan.- Unconfirmed Boundaries – Approximate, unconfirmed location ofcovenant boundaries.QEII CovPolys web 20150213 Data Definition.doc Last updated: 13/02/2015- - 2/2Attribute Format DescriptionComment Text 254 Notes on:- sources and method used for the polygon capture- further processing required for certain polygons.PrevCovNum Text 20 Previous Covenant Number – used if covenant has been renumbered orsubdivided.LastUpdate Date Date polygon last updated by QEIIQualCode Short Quality code currently used to categorise accuracy of polygons untilverification is complete:0 – cannot calculate QualCode because there is no survey area(AreaSurvHa).1 – polygon geometric area between +/- 10 – 50 % of registered surveyarea (highest quality)2 – polygon geometric area between +/- 10 – 50 % of registered survey3 – polygon geometric area between greater than +/- 50 % of registeredsurvey area (worst quality)NumBlocks Short Number of discontinuous blocks that make up the covenant. Covenants withmore than one block are represented as multi-part polygons.GeomArea Double Geometric area (in Ha) calculated by the GISQEIIRegion Text 254 Name of the QEII region containing the covenant. QEII has 27 regions, eachstaffed by a representative.CovStatus Text 10 Status of the covenant – only registered and formalised covenants shownDateRegd Date Date on which the covenant was registered.DateAppr Date Date on which the covenant was approved.AreaSurvHa Double Surveyed area of covenant at time of registration (in Ha). This figure comesfrom the QEII covenants database.Mapref Text 11 Map reference of a point giving the rough location of the covenant, defined atthe proposal stage. May not lie within the actual covenant boundary.Easting Double NZTM EastingNorthing Double NZTM Northing.WholeTitle Text 5 Yes/No field indicating whether covenant applies to a whole property(comprising one or more titles). If yes, then the covenant boundaries shouldmatch the relevant parcel boundary for the title(s). [No survey plans areprepared for whole-of-title covenants]TA_Name Text 30 Territorial AuthorityRegC_Name Text 30 Regional CouncilCoordinate SystemNew Zealand Transverse Mercator 2000.Further informationFor further information about QEII covenants or the business of the organisation, please refer to thewebsite: www.openspace.org.nzFurther details about the covenants database and GIS information are available from Joanna Haigh(Senior Advisor Geospatial Services).
