Existing Land Use

A generalized dataset of existing land use in the District of Columbia as existed during its most recent extract of the common ownership lots. This dataset is different from the Comprehensive Plan - Future Land Use, which shows land use as envisioned in the latest version of DC’s Comprehensive Plan. The primary land use categories used in this dataset are similar, but not identical. The Office of the Chief Technology Officer (OCTO) compared two datasets to create this generalized existing land use data. The data source identifying property use is the Property Use Code Lookup from the Office of Tax and Revenue (OTR). An index provided by the Office of Planning assigns each OTR property use code with a “primary land use” designation. Through an automated process, the common ownership lots were then joined with this index to create the Existing Land Use. Only properties with an assigned use code from OTR are categorized. Other properties without a use code were left as NULL. Many of these tend to be public lands such as national parks. Refer to opendata.dc.gov/pages/public-lands. This dataset has no legal status and is intended primarily as a resource and informational tool. The Office of the Chief Technology Officer anticipates replicating this work annually.本数据集为华盛顿哥伦比亚特区（District of Columbia）基于最新一次共同所有权地块提取工作生成的广义现有土地利用数据集。本数据集与《综合规划-未来土地利用》（Comprehensive Plan - Future Land Use）存在差异：后者展示的是华盛顿哥伦比亚特区最新版综合规划中拟定的土地利用方案。本数据集所采用的主要土地利用分类与前者相似，但并不完全一致。首席技术官办公室（Office of the Chief Technology Officer, OCTO）通过比对两份数据集，生成了本广义现有土地利用数据。用于识别物业用途的数据源为税务与收入办公室（Office of Tax and Revenue, OTR）提供的《物业用途代码对照表》（Property Use Code Lookup）。规划办公室（Office of Planning）提供的索引会为每个OTR物业用途代码分配“主要土地利用（primary land use）”类别标识。通过自动化流程，将共同所有权地块与该索引进行关联，最终生成现有土地利用数据集（Existing Land Use）。仅对带有OTR分配的用途代码的物业进行分类，未获取用途代码的其他物业将被标记为空值（NULL）。此类未分类物业多为公共用地，例如国家公园，相关信息可参阅opendata.dc.gov/pages/public-lands。本数据集不具备法律效力，主要用作参考资源与信息工具。首席技术官办公室计划每年复刻此项工作，实现本数据集的年度更新。
