Arizona PLSS Townships from ASLD

This dataset provides Public Land Survey System (PLSS) township and range boundaries across the State of Arizona. It serves as a foundational reference layer for land tenure, surveying, and large-scale regional planning applications. Data Origin & Modifications: Source Data: Bureau of Land Management (BLM) Cadastral National Spatial Data Infrastructure (CADNSDI) via the 2011 Geographic Information Database (GDBC) release. Enhancements: Modified by adding specific attribute fields tailored to meet the operational and reporting needs of the Arizona State Land Department (ASLD). Use Constraints & Aligned Workflows: Optimized for state agency cross-referencing and regional mapping projects requiring PLSS data structured for ASLD compatibility. For official legal boundary determinations, always refer to original BLM survey plats. Access is granted to public agencies, educational institutions, non-profit organizations and private individuals for non-commercial purpose. For commercial use of the data see Arizona Revised Statutes 39-121.03.本数据集提供亚利桑那州范围内的公共土地测量系统（Public Land Survey System, PLSS）下的镇区（township）与测区（range）边界，可作为土地权属、测量工作及大规模区域规划类应用的基础参考图层。 数据来源与修改说明： 源数据：源自2011年地理信息数据库（Geographic Information Database, GDBC）发布版中的土地管理局（Bureau of Land Management, BLM）地籍国家空间数据基础设施（Cadastral National Spatial Data Infrastructure, CADNSDI）。 改进说明：为适配亚利桑那州土地管理局（Arizona State Land Department, ASLD）的业务运营与报表需求，新增了专属属性字段。 使用限制与适配工作流：本数据集针对需要兼容亚利桑那州土地管理局格式的PLSS数据的州级机构交叉引用与区域制图项目进行了优化。若需进行正式的法定边界判定，请始终参考土地管理局原始测量图件。 本数据集向公共机构、教育机构、非营利组织及私人开放非商业性使用权限。如需进行商业性使用，请参阅《亚利桑那州修订法典》第39-121.03条。
