城市地块可以通过种植高产粮食作物来发展当地的城市粮食系统。在这里，遥感和GIS为基础的建模框架，以定位和量化的可用区域的城市农业，包括屋顶和地面水平的地区，在美国马萨诸塞州波士顿市。地理处理和空间分析工具被用来处理地理数据层的分区，所有权，坡度，土壤质量和充足的光照。通过从遥感激光雷达数据创建数字表面地图，确定了该市所有建筑物的表面坡度（屋顶坡度）。利用公开的数据集绘制了地面公共和私人空地以及未充分利用的住宅和商业区的潜在地块。已确定约922公顷的屋顶和1，250公顷的地面地块，分别占波士顿总土地面积的7.4%和10%。最后，城市常见农作物的粮食产量值被用来估计城市的粮食生产潜力，从确定的包裹。尽管波士顿人口稠密，但地图上的地区有潜力为波士顿的人口生产足够的新鲜水果和蔬菜，同时提供环境和经济的共同利益。研究结果与其他北美城市的地图和库存结果进行了比较。
Urban parcels can potentially be leveraged for developing a local urban food system by growing high yield food crops. Here, a remote sensing and GIS-based modeling framework was developed to locate and quantify available area for urban farming, including both rooftop and ground level areas in the city of Boston, MA, USA. Geoprocessing and spatial analysis tools were used to process geographic data layers for zoning, ownership, slope, soil quality, and adequate light availability. Surface slope (roof pitch) was determined for all buildings in the city through the creation of a digital surface map from remotely sensed LiDAR data. Potential parcels from ground level public and private vacant lots and underutilized residential and commercial areas were mapped using publicly available datasets. Approximately 922 ha of rooftop and 1,250 ha of ground level parcels have been identified, representing 7.4% and 10% of the total land area in Boston, respectively. Finally, food yield values for common urban agricultural crops were used to estimate the city’s food production potential from the identified parcels. Despite Boston’s density, the mapped areas have potential to produce enough fresh fruits and vegetables for Boston’s population, while providing both environmental and economic co-benefits. The study outcome was compared with mapping and inventory results from other North American cities.
