This dataset displays contours drawn at every 2m height interval. Numerous contours that are close together indicate hilly or mountainous terrain; and when far apart, they represent a gentler slope. The contours were derived from LiDAR (Light Detection and Ranging) data that was captured in 3 blocks in the years 2018 to 2019. The LiDAR point cloud has a density of 2 to 3 points per square metre at a vertical accuracy of 0.1m (95%). The contours are derived through bipolar interpolation from the 5m TIN model. The height reference used is the SA Land Levelling Datum and the SAGEOID2010 was employed.", "copyrightText": "Information & Knowledge Management Dept., Geospatial Section, 1st Floor, Keller House, 121 Loop Street, Cape Town. \nContact: Ms. Lara Röttcher, Tel. 021 487 2599, email: lara.rottcher@capetown.gov.za.\nData distributed by City Maps public counter, 7th Floor, Keller House, 121 Loop Street, Cape Town.", "editFieldsInfo": null, "ownershipBasedAccessControlForFeatures": null, "syncCanReturnChanges": false, "relationships": [], "isDataVersioned": false, "isDataArchived": false, "isCoGoEnabled": false, "modelName": "GP_12974213", "supportsRollbackOnFailureParameter": true, "archivingInfo": { "supportsQueryWithHistoricMoment": false, "startArchivingMoment": -1 }, "supportsStatistics": true, "supportsAdvancedQueries": true, "supportsValidateSQL": true, "supportsCoordinatesQuantization": true, "supportsCalculate": true, "advancedQueryCapabilities": { "supportsPagination": true, "supportsTrueCurve": true, "supportsQueryWithDistance": true, "supportsReturningQueryExtent": true, "supportsStatistics": true, "supportsHavingClause": true, "supportsOrderBy": true, "supportsDistinct": true, "supportsCountDistinct": true, "supportsQueryWithResultType": true, "supportsReturningGeometryCentroid": false, "supportsSqlExpression": true }, "extent": { "xmin": 2037609.9277226466, "ymin": -4077159.5752888885, "xmax": 2115730.0747071006, "ymax": -3957810.609717995, "spatialReference": { "wkid": 102100, "latestWkid": 3857 } }, "sourceSpatialReference": {"wkt": "PROJCS[\"Transverse_Mercator\",GEOGCS[\"GCS_HARTEBEESTHOEK_1994\",DATUM[\"D_HARTEBEESTHOEK_1994\",SPHEROID[\"GRS_1980\",6378137.0,298.257222101]],PRIMEM[\"Greenwich\",0.0],UNIT[\"Degree\",0.0174532925199433]],PROJECTION[\"Transverse_Mercator\"],PARAMETER[\"false_easting\",0.0],PARAMETER[\"false_northing\",0.0],PARAMETER[\"central_meridian\",19.0],PARAMETER[\"scale_factor\",1.0],PARAMETER[\"latitude_of_origin\",0.0],UNIT[\"Meter\",1.0]]"}, "drawingInfo": { "renderer": { "type": "simple", "symbol": { "type": "esriSLS", "style": "esriSLSSolid", "color": [ 0, 0, 0, 255 ], "width": 0.4 }, "label": "", "description": "" }, "transparency": 0, "labelingInfo": null }, "hasM": false, "hasZ": false, "allowGeometryUpdates": false, "allowTrueCurvesUpdates": false, "onlyAllowTrueCurveUpdatesByTrueCurveClients": false, "hasAttachments": false, "supportsApplyEditsWithGlobalIds": false, "htmlPopupType": "esriServerHTMLPopupTypeAsHTMLText", "objectIdField": "OBJECTID", "globalIdField": "", "displayField": "NAME", "typeIdField": "", "subtypeField": "", "fields": [ { "name": "OBJECTID", "type": "esriFieldTypeOID", "alias": "OBJECTID", "domain": null, "editable": false, "nullable": false, "defaultValue": null, "modelName": "OBJECTID" }, { "name": "NAME", "type": "esriFieldTypeString", "alias": "Name", "domain": null, "editable": true, "nullable": true, "length": 6, "defaultValue": null, "modelName": "NAME" }, { "name": "CLSD_CNTR", "type": "esriFieldTypeString", "alias": "Closed Contour", "domain": null, "editable": true, "nullable": true, "length": 3, "defaultValue": null, "modelName": "CLSD_CNTR" }, { "name": "ELVT", "type": "esriFieldTypeDouble", "alias": "Elevation", "domain": null, "editable": true, "nullable": true, "defaultValue": null, "modelName": "ELVT" } ], "geometryField": { "name": "Shape", "type": "esriFieldTypeGeometry", "alias": "Shape", "domain": null, "editable": false, "nullable": true, "defaultValue": null, "modelName": "Shape" }, "indexes": [ { "name": "R472_pk", "fields": "OBJECTID", "isAscending": true, "isUnique": true, "description": "" }, { "name": "S424_idx", "fields": "Shape", "isAscending": true, "isUnique": true, "description": "" } ], "dateFieldsTimeReference": { "timeZone": "UTC", "respectsDaylightSaving": false }, "types": [], "templates": [ { "name": "Ground Level Map 2m Contours", "description": "", "prototype": { "attributes": { "CLSD_CNTR": null, "ELVT": null, "NAME": null } }, "drawingTool": "esriFeatureEditToolLine" } ], "maxRecordCount": 250000, "supportedQueryFormats": "JSON, geoJSON", "capabilities": "Query,Extract", "useStandardizedQueries": true, "standardMaxRecordCount": 8000, "tileMaxRecordCount": 4000, "maxRecordCountFactor": 1 }
