Kentucky (KyFromAbove) Phase 3 Oblique Imagery Centroids with Camera Bearing

4,428,945 point features representing centroid locations for oblique aerial imagery captured as part of Kentucky's KYAPED (Kentucky Aerial Photography and Elevation Data) Phase 3 collection program, a component of the KyFromAbove statewide imagery initiative. The dataset spans three collection years: 2023 (2,464,925 images), 2024 (1,927,325 images) 2022 (36,695 images) The majority of imagery was captured during Season 1, Spring (4,068,655 images), with additional collection in Season 2, Fall (360,290 images). Each point represents the center location of an individual aerial photograph, with flight lines running in alternating North and South directions (approximately 2.2 million images each). The dataset includes imagery from five camera positions on each aircraft: Color (885,789) – nadir/vertical view Forward (Fwd) and Backward (Bwd) (885,789 each) – oblique views along the flight line Left and Right (885,789 each) – oblique views perpendicular to the flight path Camera directions are recorded as North, South, East, or West based on the aircraft's heading, enabling users to select imagery with specific viewing angles for a location. The data encompasses 2,553 unique flight lines with 3-inch resolution imagery. Key attributes include filename, flight date and time, flight line ID, shot ID, collection year and season, and a direct S3 URL link to access each image from the KyFromAbove cloud storage. This index layer enables efficient discovery and retrieval of oblique imagery for applications including infrastructure inspection, change detection, emergency response, and detailed site analysis across Kentucky.本数据集包含4,428,945个点要素，代表肯塔基州KYAPED（肯塔基航空摄影与高程数据，Kentucky Aerial Photography and Elevation Data）第三阶段采集项目所获取的倾斜航空影像（oblique aerial imagery）的质心位置，该项目是KyFromAbove全州影像计划的组成部分。数据集涵盖三个采集年份：2023年（2,464,925张影像）、2024年（1,927,325张影像）及2022年（36,695张影像）。绝大多数影像采集于第一季春季（4,068,655张影像），另有秋季（第二季）采集的360,290张影像。每个点对应单张航空影像的中心位置，飞行航线沿南北方向交替布设，两个方向各约220万张影像。数据集包含每架飞行器的五类相机机位影像：彩色相机（885,789张）——天底垂直视角（nadir/vertical view）；前向（Fwd）与后向（Bwd）相机（各885,789张）——沿飞行航线的倾斜视角；左向与右向相机（各885,789张）——垂直于飞行路径的倾斜视角。相机朝向根据飞行器航向记录为北、南、东或西，方便用户针对特定位置选取符合需求的视角影像。本数据集涵盖2,553条独特飞行航线的3英寸分辨率航空影像，核心属性包括文件名、飞行日期与时间、航线ID、拍摄ID、采集年份与季节，以及指向KyFromAbove云存储中每张影像的直接S3 URL链接。此索引图层可实现倾斜影像的高效发现与检索，应用场景覆盖肯塔基州范围内的基础设施巡检、变化检测、应急响应及精细化场地分析等。
