Land Use

Polygon layer of land use within Johnson City, City limits, Was originally developed in 2010 by using parcels, 2007 aerials, and some supplemental field work. Layer was completely quality control checked again in 2012 to the newer 2011 aerial data. Data is now kept up-to-date through weekly permitting reports from Codes Division. It was the decision of the original builders of the data to just use parcels and not include the right-of-way (ROW) area.约翰逊市（Johnson City）市域范围内的土地利用多边形图层，最初于2010年依托宗地数据、2007年航空影像及部分补充野外实地调查工作建成。2012年，针对更新的2011年航空影像数据，该图层完成了全面的质量控制复核。目前，该数据集通过法规管理部门（Codes Division）每周提交的许可申报报告实现动态更新。该数据集的原始构建者决定仅采用宗地数据，不包含道路通行权（right-of-way, ROW）区域。
