1989 General Landcover Map of the Eastern Shore of Virginia

This generalized landcover classification of the Eastern Shore of Virginia focuses on major landforms and habitats of the Virginia Coast Reserve LTER. The classification is based on a Landsat 5 Thematic Mapper (TM) satellite image taken on July 25, 1989 at 15:14 GMT (11:14 EDT), which is roughly concurrent with mid-tide water levels as predicted for Wachapreague, VA (L=8:25, H=14:52 EDT). The classification divides the landscape into three components: water (code 1); salt marsh (code 2); and upland/mainland areas (code 3). The primary purpose of this dataset is to provide a background map layer over which VCRLTER researchers and students can plot individual research site locations for figures intended for publications and presentations.本数据集为弗吉尼亚东海岸的通用土地覆盖分类成果，聚焦弗吉尼亚海岸保护区长期生态研究站点（Virginia Coast Reserve LTER）的主要地貌与生境类型。本次分类基于1989年7月25日15:14 GMT（即美国东部夏令时11:14）获取的陆地卫星5号主题制图仪（Landsat 5 Thematic Mapper, TM）卫星影像，该影像成像时刻大致与弗吉尼亚州瓦卡普雷格（Wachapreague, VA）预报的中期潮水位相吻合（当日该区域低潮时刻为8:25 EDT，高潮时刻为14:52 EDT）。本次分类将研究区地表划分为三类要素：水体（编码1）、盐沼（编码2）以及高地/陆地区域（编码3）。本数据集的核心用途是提供一幅背景底图图层，供弗吉尼亚海岸保护区长期生态研究站点（VCRLTER）的研究人员与学生绘制用于学术发表或汇报的单个研究样地点位图。
