GEOINT — Photo & Video

GEOINT — 照片与视频

Determine where and when an image was taken and whether it is authentic. Input: a photo or video file or URL.

确定图像的拍摄地点和时间，以及其是否真实可信。输入：照片或视频文件，或其URL。

Step 1 — Authorized scope

步骤1 — 授权范围

Read ../../ETHICS.md. Note the objective (verification, missing person, disinformation). Done when noted.

阅读../../ETHICS.md。明确目标（验证身份、寻找失踪人员、识别虚假信息）。完成标志：已记录目标。

Step 2 — Metadata (fast win)

步骤2 — 元数据（快速获取信息）

Run

exif-metadata-analysis

: EXIF may contain exact GPS coordinates, a timestamp, and the camera/phone model. If present, you may be done — but treat metadata as a claim to verify, since it is easily stripped or faked. Done when EXIF is extracted or confirmed absent.

运行

exif-metadata-analysis

：EXIF可能包含精确的GPS坐标、时间戳以及相机/手机型号。如果存在这些信息，你可能已完成初步分析，但需将元数据视为待验证的声明，因为它很容易被剥离或伪造。完成标志：已提取EXIF数据，或确认不存在EXIF数据。

Step 3 — Provenance

步骤3 — 来源溯源

Run

reverse-image-search

(Google Lens, Yandex — strongest for places — Bing, TinEye) to find earlier appearances, the original source, and the true date. Run

media-verification

to check for manipulation and confirm it isn't a recycled or AI-generated image. Done when the earliest known appearance and authenticity are established.

运行

reverse-image-search

（Google Lens、Yandex——在地点识别方面表现最佳——Bing、TinEye）以查找该媒体的早期出现记录、原始来源以及真实日期。运行

media-verification

以检查是否存在篡改情况，并确认该图像并非重复使用或AI生成的。完成标志：已确定最早的已知出现记录，并确认真实性。

Step 4 — Chronolocation from pixels

步骤4 — 基于像素的时间地理定位

When there's no metadata, geolocate from the image itself. Run

chronolocation

: read signs, languages, license plates, architecture, flora, power/utility styles, road markings, and business names; match to satellite/street imagery (Google Earth, Yandex Maps, Mapillary); use sun position and shadows to bound the time of day and season. Done when you have a candidate location, ideally narrowed to a specific site.

当没有元数据时，从图像本身进行地理定位。运行

chronolocation

：识别标识、语言、车牌、建筑风格、植物、电力/公用设施样式、道路标线和企业名称；与卫星/街景图像（Google Earth、Yandex Maps、Mapillary）进行匹配；利用太阳位置和阴影确定拍摄的时间段和季节。完成标志：已找到候选地点，理想情况下可缩小到具体位置。

Step 5 — Confirm

步骤5 — 确认

Corroborate the candidate against a second source: Street View match of the same building, a geotagged photo of the same spot, or terrain overlap. Location is confirmed only when independent imagery matches. Done when the location is confirmed or listed as best-estimate with confidence.

通过第二个来源佐证候选地点：同一建筑的街景匹配、同一地点的带地理标签照片，或地形重叠。只有当独立图像匹配时，地点才被确认。完成标志：已确认地点，或列出置信度明确的最佳估计地点。

Step 6 — Report

步骤6 — 报告

Run

osint-report

. Give coordinates, a confidence level, and the specific visual clues that pin the location, with reference imagery links.

运行

osint-report

。提供坐标、置信度，以及确定地点的具体视觉线索，并附上参考图像链接。
