The 5km x 5km aerial photography grid was developed in the 1980s by the old Regional Services Council. Its practical use is to provide a unique number for each tile of 5km x 5km aerial (ortho) photography when dealing with aerial contractors and for planning purposes. Furthermore, it can be used as a useful reference guide to identify area's of interest for other geospatial work. The rectangular grid intersection co-ordinates are in Gauss Conform using positive Westings and Southings. The top right corner origin falls on the Lo19 Meridian and is at y = 0 and x = 3 700 000. Each 10km x 10km geocell (see CCT 10km x 10km Grid) is divided into four 5km x 5km cells, named A, B, C, D. The reference for each 10km x 10km geocell is derived from the top right corner and is made up of two digits \u2013 the first being the first digit of the y value and the second being the third digit of the x value. For example the geocell with a top right hand corner value y = + 30 000 and x = + 3 740 000 would have a reference of 34. In addition the letter W is added in front if the cell is located west of the Lo19 Meridian and the letter E is added if located east of the Lo19 Meridian.The 5km x 5km grid numbers are as follows: W00A, W00B, W00C, W00D, W10A, W10B, W10C, W10D, W20A\u2026 One row of cells is added to the east of the Lo19 Meridian: E00A, E00C, E01A, E01C, E02A, E02C\u2026.One row of geocells in the south has duplicate numbers going beyond x = 3 800 000. For example: Y = 50 000 and x = 3 700 000 gives W50B (North)Y = 50 000 and x = 3 800 000 gives W50B (South)Therefore, duplicate 10km x 10km tiles have been suffixed with a N for tiles lying in the north or S for for tiles lying in the south. In this case, W50N_B and W50S_B.", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkt2": "PROJCRS[\"WGS_1984_Transverse_Mercator\",BASEGEOGCRS[\"GCS_WGS_1984\",DATUM[\"D_Hartebeesthoek_1994\",ELLIPSOID[\"WGS_1984\",6378137.0,298.257223563,LENGTHUNIT[\"Meter\",1.0]]],PRIMEM[\"Greenwich\",0.0,ANGLEUNIT[\"Degree\",0.0174532925199433]],CS[ellipsoidal,2],ANGLEUNIT[\"Degree\",0.0174532925199433]],CONVERSION[\"Transverse_Mercator\",METHOD[\"Transverse_Mercator\"],PARAMETER[\"False_Easting\",0.0,LENGTHUNIT[\"Meter\",1.0]],PARAMETER[\"False_Northing\",0.0,LENGTHUNIT[\"Meter\",1.0]],PARAMETER[\"Central_Meridian\",19.0,ANGLEUNIT[\"Degree\",0.0174532925199433]],PARAMETER[\"Scale_Factor\",1.0,SCALEUNIT[\"Unity\",1.0]],PARAMETER[\"Latitude_Of_Origin\",0.0,ANGLEUNIT[\"Degree\",0.0174532925199433]]],CS[Cartesian,2],AXIS[\"Easting (X)\",east,ORDER[1]],AXIS[\"Northing (Y)\",north,ORDER[2]],LENGTHUNIT[\"Meter\",1.0]]", "wkt": "PROJCS[\"WGS_1984_Transverse_Mercator\",GEOGCS[\"GCS_WGS_1984\",DATUM[\"D_Hartebeesthoek_1994\",SPHEROID[\"WGS_1984\",6378137.0,298.257223563]],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]]", "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -5623200, "falseY": -10002100, "xyUnits": 10000, "falseZ": 0, "zUnits": 1, "falseM": 0, "mUnits": 1 }, "copyrightText": "Information & Knowledge Management Dept., Geospatial Section, 1st Floor, Keller House, 121 Loop Street, Cape Town.
