USGS Southwest Repeat Photography Collection: Kanab Creek, southern Utah and northern Arizona, 1872-2010: Stake 1504a

This metadata record describes the materials contained in stake folder 1504a. Stake 1504a is located at latitude 36.39233, longitude -112.62859. This location was photographed in the following years: 1890, 1990 and 2010. The materials associated with this item include original best quality images from each repeat date (preserved as digitized film images or in some cases digitized print photographs, depending on availability), scanned film envelopes with camera metadata, records of repeat photography sheets, and all field notes and/or camera notes associated with this stake. All attachments follow the following naming convention: stake_date_material_type_Kanab. Some stakes will have multiple materials from one repeat date (e.g., duplicate images with distinct descriptive information, a color negative and a color positive version of an image, etc.) Some stakes will have materials labeled 'unknown', indicating that the physical image or note was unlabeled and therefore couldn't be categorized by date.本元数据记录对编号为1504a的标记桩文件夹所收纳的全部资料进行了说明。该标记桩1504a的坐标为北纬36.39233°、西经112.62859°，该点位分别于1890年、1990年及2010年完成了摄影采集。本条目关联的资料涵盖各次重复摄影拍摄的原始高质量影像（依据留存可用性，分别以数字化胶片图像或数字化冲印照片的形式保存）、附带相机元数据的扫描胶片信封、重复摄影记录表，以及与该标记桩相关的全部野外记录和/或相机操作记录。所有附件均遵循如下命名规则：stake_date_material_type_Kanab。部分标记桩的单次重复摄影拍摄会对应多份资料，例如带有不同描述信息的重复影像、同一影像的彩色负片与彩色正片版本等。另有部分标记桩的资料会被标注为"unknown"，这表示实体影像或记录未附带标签，因此无法按拍摄日期进行分类。
