SFWMD Land Use 2012 - LWC and UEC Update

This polygon feature class documents the extent and type of land use within the Lower West Coast (LWC) and the Upper East Coast (UEC)Planning Regions of the South Florida Water Management District as it existed in 2011-2012. Land Use data were updated from 2008-09 LCLU by photo-interpretation from 2011-2013 aerial photography and classified using the SFWMD modified FLUCCS classification system. Features were interpreted from the county-based aerial photography (1 ft pixel) and updated on screen from the 2008-09 vector data. Horizontal accuracy of the data corresponds to the positional accuracy of the county aerial photography. The minimum mapping unit for classification was 2 acres for wetlands and 5 acres for uplands. The update was completed on 11/13/2014. This dataset was previously referred to as the 2014 update. The classification system used for this project was the Florida Land Use, Cover and Forms Classification System (FLUCCS), which was originally compiled by the Florida Department of Transportation, State Topographic Bureau. The classification system was amended by the District for use on this project and these amendments are described within this document. Only Land Use was considered for this project. https://geoext.geoapps.sfwmd.gov/TPubs/2012_Land_Use_FLUCCs_Codes.pdf本多边形要素类记录了2011-2012年期间，南佛罗里达水资源管理区（South Florida Water Management District，SFWMD）下属的下西海岸（Lower West Coast，LWC）与东海岸上部（Upper East Coast，UEC）规划区域内的土地利用范围与类型。本次土地利用数据以2008-09年土地覆盖与土地利用（Land Cover and Land Use，LCLU）数据为基础，通过对2011-2013年航空影像开展目视解译，并采用经南佛罗里达水资源管理区修订的佛罗里达土地利用、覆盖与形态分类系统（Florida Land Use, Cover and Forms Classification System，FLUCCS）完成分类。要素信息由县域级航空影像（像素分辨率1英尺）解译得到，并基于2008-09年矢量数据在屏幕上完成更新。本数据的水平定位精度与县域航空影像的定位精度保持一致。本次分类的最小上图图斑面积为：湿地2英亩，旱地5英亩。本次数据更新于2014年11月13日完成，该数据集此前曾被称为2014版更新数据。本项目采用的分类系统最初由佛罗里达州交通部州地形局编制，本次实施过程中南佛罗里达水资源管理区对其进行了修订，修订细节详见本文档。本次项目仅针对土地利用要素开展分类工作。相关参考文档可访问：https://geoext.geoapps.sfwmd.gov/TPubs/2012_Land_Use_FLUCCs_Codes.pdf
