Description: Objective:An integrated simplified land cover for the Eastern Cape Province combining the DEA/GTI 2013/2014 National Land Cover, ARC degradation, STEP degradation, SANBI Fields and Richard Lechmere-Oertel ANDM land cover into a single land cover at 30m resolution.Input Layers:Primary Input Layer:GTI 2014 National Land Cover (sa_lcov_2013-14_gti_utm35s_vs22b)Additional “Degradation”layers:ARC degradation (Degraded Land_E Cape Clip NEW.shp)ARC dongas (gullies_EC_GCSwgs84_Oct2010.shp)STEP Transformation (\\WMA12\data_imvelo\STEP_SCP\8Transformation\STEP_Transformation_gw.shp)ANDM land cover RLO (richard.bpm@gmail.com) erosion and aliensMkambati expansion land cover RLO erosion and aliensAdditional “Old Field”layers:SANBI old fields (\\Fields_Old_SANBI\Fields_old.shp)Field Crop Boundaries RSA dataset (EC_040407_ll.shp)ANDM land cover RLO fieldsMkambati expansion land cover RLO fieldsARC Degradation RE-Classification for the Land Cover:FIDDESCRIPTIOclassARC_DEGR0Barren rockBarren rockNot Included1Degraded: forest and woodlandDegraded vegetation12Degraded: herblandDegraded vegetation13Degraded: shrubland and low FynbosDegraded vegetation14Degraded: thicket & bushland (etc)Degraded vegetation15Degraded: unimproved grasslandDegraded vegetation16Dongas & sheet erosion scarsDongas*1* Dongas here are classed as “degraded vegetation”as the ARC Gully map is much higher resolution.For some reason the ARC Field Crop Boundaries RSA dataset did not want to convert from shp polygon to Raster in ArcGIS. Therefore did the following:Add EC_040407_ll_U34s.shp to WhiteboxConvert to raster with 30m cell sizeExport output to flt fileIn ArcGIS import flt fileDefine projection (U35s)Reclass flt file changing all values to 1 (i.e. 1 = field) and set extent to and snap to LC_2014Shift output east by 30m (i.e. 1 cell) to better align with LC_2014Output = Fields_RSAOther potential layers not used:ARC Predicted Soil Loss E Cape Clip NEW.shp and ARC Water Erosion_E Cape Clip NEW.shp –Both layers are modelled based on Land Types and therefore not an interpretation of actual underlying thematic data.Integrated Land Cover (field: LC_INT) combine rules:If LC_2014 = Not Natural, THEN LC_INT = “LC_2014 RECLASS1”If LC_2014 = Natural AND Field = TRUE, THEN LC_INT = “Old Field”If LC_2014 = Natural AND Field = FALSE AND Degradation = TRUE, THEN LC_INT = “Degraded”If LC_2014 = Natural AND Field = FALSE AND Degradation = FALSE, THEN LC_INT = “Natural”LC classifications:LC_CLASS = Original national 2013/14 land cover categoriesLC_INT = Integrated land cover categories taking into account degradation and old fieldsLC_5CLASS = simplified land cover classification to be used in defining planning units (degradation combined with natural land class)LC_INT categories:DegradedDryland FieldsIrrigated FieldsMiningNaturalOld FieldsPlantationsSettlementWaterLC_5CLASS categories:NaturalOld FieldsFieldsPlantationsSettlementClassification Table:LC_5CLASSLC_INTLC_CLASSFieldsDryland FieldsCultivated comm fields (high)Cultivated comm fields (low)Cultivated comm fields (med)Cultivated subsistence (high)Cultivated subsistence (low)Cultivated subsistence (med)FieldsIrrigated FieldsCultivated comm pivots (high)Cultivated comm pivots (low)Cultivated comm pivots (med)Cultivated orchards (high)Cultivated orchards (low)Cultivated orchards (med)Cultivated permanent pineappleSettlementMiningMine buildingsMines 1 bareMines 2 semi-bareMines water permanentMines water seasonalNaturalDegradedBare none vegetatedErosion (donga)GrasslandIndigenous ForestLow shrublandShrubland fynbosThicket /Dense bushWoodlan/Open bushNaturalBare none vegetatedErosion (donga)GrasslandIndigenous ForestLow shrublandShrubland fynbosThicket /Dense bushWoodlan/Open bushOld FieldsOld FieldsBare none vegetatedErosion (donga)GrasslandIndigenous ForestLow shrublandShrubland fynbosThicket /Dense bushWoodlan/Open bushPlantationsPlantationsPlantation / Woodlots clearfelledPlantation / Woodlots youngPlantations / Woodlots matureSettlementSettlementUrban built-up (bare)Urban built-up (dense trees / bush)Urban built-up (low veg / grass)Urban built-up (open trees / bush)Urban commercialUrban industrialUrban informal (bare)Urban informal (dense trees / bush)Urban informal (low veg / grass)Urban informal (open trees / bush)Urban residential (bare)Urban residential (dense trees / bush)Urban residential (low veg / grass)Urban residential (open trees / bush)Urban school and sports groundUrban smallholding (bare)Urban smallholding (dense trees / bush)Urban smallholding (low veg / grass)Urban smallholding (open trees / bush)Urban sports and golf (bare)Urban sports and golf (dense tree / bush)Urban sports and golf (low veg / grass)Urban sports and golf (open tree / bush)Urban township (bare)Urban township (dense trees / bush)Urban township (low veg / grass)Urban township (open trees / bush)Urban village (bare)Urban village (dense trees / bush)Urban village (low veg / grass)Urban village (open trees / bush)NaturalWaterWater permanentWater seasonalWetlands
