Land Use 2010

Every five years, since 1990, the Delaware Valley Regional Planning Commission has produced a GIS Land Use layer for its 9-county region. As it was in 2000, digital orthophotography was flown by DVRPC in 2010. Digitizing was done using these 2010 true-color aerials on the ESRI ArcGIS software platform at a 1:2400 (1 inch = 200 feet) scale.自1990年起，特拉华谷区域规划委员会（Delaware Valley Regional Planning Commission, DVRPC）每五年便会为其下辖的9个县区域生成地理信息系统（Geographic Information System, GIS）土地利用图层。2010年，该委员会一如2000年的做法，完成了数字正射影像航拍作业。本次数字化工作以ESRI ArcGIS软件为平台，采用1:2400（即1英寸对应200英尺）的比例尺，基于2010年获取的真彩色航空影像完成。
