Historic Cemeteries of Frederick County, Maryland

Overview This feature service provides spatial locations and relevant attribute information for historic cemeteries and burial sites within Frederick County, Maryland. The dataset serves historic preservation, planning, and cultural resource management purposes by documenting cemeteries referenced in historical records. Feature Layer Historic Cemeteries: This layer includes mapped locations of historic cemeteries identified from the indices and location maps of the books "Names In Stone" and "More Names In Stone" by Jacob M. Holdcraft. Locations were refined using georeferenced maps, aerial imagery, USGS topographic maps, Maryland SDAT records, plat records, and Pictometry imagery. The layer categorizes the cemetery locations based on location certainty: Located - cemeteries platted or clearly visible in aerial imagery. Approximately Located - cemeteries with spatial positions derived from georeferenced maps without precise imagery confirmation, mainly family cemeteries. Location Unknown - cemeteries referenced but spatially undetermined, including a few outside Frederick County. Attribute data such as cemetery name, place name, reference number, and field verification status support contextual understanding and future dataset enhancement. Geographic Coverage The dataset focuses exclusively on Frederick County, Maryland, documenting burial sites important to the county’s historical and cultural heritage. Source and Citation Information originates from the published works of Jacob M. Holdcraft (1966, 1972), which compiled over 75,000 cemetery inscriptions and location data for the region. These authoritative sources underpin the quality and historic significance of this dataset. Use Cases Supporting historic preservation and cultural resource planning initiatives. Facilitating research into genealogical and local history related to burial customs and cemetery locations. Assisting land use planning and legal considerations involving historic cemeteries.概览 本要素服务（Feature Service）提供美国马里兰州弗雷德里克县境内历史墓地与丧葬遗址的空间位置及相关属性信息。本数据集通过收录历史文献中记载的墓地信息，服务于历史保护、规划制定与文化资源管理工作。 历史墓地要素图层（Historic Cemeteries Feature Layer） 本图层收录了由Jacob M. Holdcraft所著《Names In Stone》（《石刻名录》）与《More Names In Stone》（《续石刻名录》）的索引及位置图中识别出的历史墓地的制图位置。其点位通过地理参考地图、航空影像、美国地质调查局（USGS）地形图、马里兰州SDAT档案、地块档案以及Pictometry影像进行了精修。 本图层根据点位确定性对墓地位置进行分类： 1. 已定位（Located）：已完成地籍标注或可在航空影像中清晰识别的墓地； 2. 近似定位（Approximately Located）：通过地理参考地图推导空间位置，但未获得精确影像验证的墓地，此类以家族墓地为主； 3. 未知定位（Location Unknown）：仅见文献记载但空间位置未明确的墓地，其中包含少量位于弗雷德里克县境外的墓地。 属性数据 墓地名称、地名、参考编号以及野外验证状态等属性数据，有助于理解数据上下文信息并支持后续数据集的优化完善。 地理覆盖范围 本数据集仅覆盖美国马里兰州弗雷德里克县，收录对该县历史文化遗产具有重要价值的丧葬遗址。 来源与引用 本数据集信息源自Jacob M. Holdcraft分别于1966年、1972年出版的著作，其收录了该区域超过75000条墓地铭文与位置数据。这些权威来源为本数据集的质量与历史价值提供了坚实支撑。 应用场景 支持历史保护与文化资源规划相关工作；助力与丧葬习俗、墓地位置相关的家谱学与地方史研究；辅助涉及历史墓地的土地利用规划与法律考量。
