Forest Damages – Larch Casebearer

The larch casebearer, Coleophora laricella, is a moth that mainly attacks larch trees and has caused significant damage in larch stands in Västergötland, Sweden. The Swedish Forest Agency, supported by Microsoft’s AI for Earth program, started a project that utilizes artificial intelligence for identifying, inventorying, mapping, and monitoring forest areas affected by the larch casebearer. The primary intention of the project is to help forest caretakers to quickly identify threats and react to prevent further forest damage. This dataset is an outcome of the project, and it contains 1,543 images taken from two drone flying occasions over five affected areas in Västergötland, Sweden. The data set is structured in 10 batches, numbered 1 to 10. All batches contain bounding box annotations around trees, categorized as Larch and Other. These annotations can be used to train AI models for tree identification. In 1,543 images, there are 101,878 annotated trees. Batches 1-5 also contain annotations describing tree damage in four categories: Healthy (H), Light Damage (LD), High Damage (HD), and Other. These annotations can be used to train models for damage classification. In 840 images there are 44,522 larch trees annotated with damage level.

落叶松袋蛾，学名 Coleophora laricella，是一种主要侵袭落叶松的蛾类，在瑞典韦斯特哥特兰的落叶松林中造成了显著的损害。瑞典森林管理局，在微软地球AI计划的资助下，启动了一项利用人工智能进行受落叶松袋蛾影响的森林区域识别、清点、制图和监测的项目。该项目的首要目的是协助森林管理者迅速识别威胁并做出反应，以预防进一步的森林损害。本数据集是该项目的成果，其中包含从瑞典韦斯特哥特兰五个受影响区域拍摄的1,543张无人机图像。数据集结构分为10个批次，编号从1至10。所有批次均包含围绕树木的边界框标注，分为落叶松和其他类别。这些标注可用于训练用于树木识别的AI模型。在1,543张图像中，共有101,878棵树木被标注。批次1至5还包含描述树木损害程度的四个类别的标注：健康（H）、轻度损害（LD）、重度损害（HD）和其他。这些标注可用于训练用于损害分类的模型。在840张图像中，共有44,522棵落叶松树木被标注了损害程度。
