Plant detection dataset from Mapillary images in Guadeloupe
收藏资源简介:
This dataset contains automated plant identification results derived from onboard vehicle (wardriving) camera data in Guadeloupe, using Mapillary imagery and the Pl@ntNet API for species recognition. This dataset contains results of automated queries to the Mapillary API for a large bounding box covering the main islands of Guadeloupe (Basse-Terre, Grande-Terre, Marie Galante). The bounding box coordinates were set to [-61.9, 15.9, -61.1, 16.6], and the queries were performed on 2025-02-12. Each returned Mapillary image was then sent to the Pl@ntNet API to attempt automatic identification of the plant visible in that image. The dataset is stored as a CSV file with one row per image. Below is a description of each column: image_id A unique identifier for the Mapillary image. lat Latitude of the image (WGS84). lon Longitude of the image (WGS84). capture_date Unix timestamp (in milliseconds) corresponding to the date/time the image was captured. image_url Direct link to the image resource as hosted on Mapillary associated CDN. best_match_scientific_name The top-ranked plant species name returned by Pl@ntNet. If the field is “Not Found,” it means the Pl@ntNet API did not return a valid species match (e.g., status code 404). best_match_probability Probability (score) associated with the best_match_scientific_name, as provided by Pl@ntNet. May be empty or zero when no valid species was found. plantnet_data A JSON string containing the full set of results from Pl@ntNet. Includes details such as predicted organs, alternative species suggestions, taxonomic information, and associated metadata. Data Collection Method The Mapillary API was queried systematically across the bounding box ([-61.9, 15.9, -61.1, 16.6]) on 2025-02-12, retrieving available images taken along roads or other traversable paths. For each image, the latitude, longitude, and capture date were extracted. Each image was then submitted to the Pl@ntNet API for plant identification. Only the best match (top-ranked species) and the associated probability are recorded in specific columns, while the entire Pl@ntNet response is stored under plantnet_data. Notes and Caveats Single-species assumption: Each image is labeled with at most one best match species. In reality, scenes may contain multiple plant taxa; however, for simplicity, this dataset focuses on the top match returned by Pl@ntNet. Full results are nevertheless stored in the plantnet_data column. Spatial bias: Data covers only roads and areas with Mapillary coverage at the time of querying. Temporal mismatch: The capture_date of each image can vary widely; it is not uniform across all images. This can introduce seasonal or inter-annual discrepancies in plant appearance. Accuracy: Automated identification may yield false positives or imprecise probabilities, especially if the plant is partially obscured, out of focus, or not a common species in Pl@ntNet’s training set.

本数据集包含来自瓜德罗普岛车载(道路巡航)摄像头数据的自动化植物识别结果,所用数据为Mapillary影像,并通过Pl@ntNet API进行物种识别。 本数据集包含针对覆盖瓜德罗普主岛(巴斯特尔岛、格兰德特尔岛、玛丽加兰特岛)的大型边界框的Mapillary API自动化查询结果。该边界框的坐标设置为[-61.9, 15.9, -61.1, 16.6],查询于2025年2月12日执行。每一张返回的Mapillary影像随后都会被提交至Pl@ntNet API,以尝试自动识别该影像中的植物。 本数据集以逗号分隔值(CSV)文件形式存储,每张影像对应一行数据。以下为各列的详细说明: image_id:Mapillary影像的唯一标识符。 lat:影像的纬度(WGS84坐标系)。 lon:影像的经度(WGS84坐标系)。 capture_date:影像拍摄日期与时间对应的Unix时间戳(单位:毫秒)。 image_url:指向Mapillary关联内容分发网络(CDN)所托管影像资源的直接链接。 best_match_scientific_name:Pl@ntNet返回的排名第一的植物物种学名。若该字段为“未找到”,则表示Pl@ntNet API未返回有效的物种匹配结果(例如状态码404)。 best_match_probability:Pl@ntNet提供的与best_match_scientific_name相关联的概率得分。当未找到有效物种时,该字段可能为空或为零。 plantnet_data:包含Pl@ntNet完整返回结果的JSON字符串。其中涵盖预测器官、备选物种建议、分类学信息及相关元数据等详细内容。 数据采集流程:2025年2月12日,我们对边界框[-61.9, 15.9, -61.1, 16.6]范围内进行系统性的Mapillary API查询,获取沿道路或其他可通行路径拍摄的可用影像。随后提取每张影像的纬度、经度及拍摄日期。每张影像随后都会被提交至Pl@ntNet API进行植物识别。仅将最佳匹配(排名第一的物种)及其关联概率记录至对应列中,而Pl@ntNet的完整响应则存储于plantnet_data列下。 注意事项与局限性: 1. 单物种假设:每张影像仅标注最多一个最佳匹配物种。实际场景中可能包含多种植物类群,但为简化处理,本数据集仅关注Pl@ntNet返回的顶级匹配结果。不过完整的识别结果仍存储于plantnet_data列中。 2. 空间偏差:数据仅覆盖查询时Mapillary有影像覆盖的道路及区域。 3. 时间不匹配:每张影像的拍摄日期(capture_date)差异较大,并非统一分布,这可能会在植物外观上引入季节或年际差异。 4. 识别精度:自动化植物识别可能会产生假阳性结果或概率不准确的情况,尤其是当植物部分被遮挡、对焦模糊,或该物种并非Pl@ntNet训练集中的常见物种时。 许可与使用条款: Mapillary影像遵循知识共享署名-相同方式共享(CC-BY-SA)许可协议(详见对应页面)。 Pl@ntNet使用数据需遵循Pl@ntNet的许可及使用政策。 致谢 感谢Mapillary平台提供街景影像访问权限并支持社区化数据采集。 感谢Pl@ntNet团队通过API开放植物识别服务。 本数据集仅用于研究与教育目的。若该数据集对您的出版物或项目有所贡献,我们鼓励您引用本数据集存档。
