土地利用语义照片数据集（LSPD）按三层架构（土地利用类型/语义/实景照片）设计，是国土调查领域第一个支持地表实景照片土地利用分类的掩膜数据集，具有支持类别广、样本数量大、场景噪声低的特点。 实景照片采集自全国七大地理区域，目前已支持44类地表景观语义，每类照片2000×3张，每个标记样本以三种形态（原始场景照片、矩形分割场景照片、掩膜分割场景照片）保存，部分样本增强后，总样本量140多万张，照片包含拍摄位置信息。LSPD已成功应用于第三次国土调查照片自动核查工作，优良的三层体系设计使其也能很好的服务于其它类型的资源调查（如水资源、林业资源和农业资源等）。
Land-use Semantic Photo Dataset (LSPD) is designed according to the
three-layer structure (land-use category/semantic/landscape photo),and it is
the first masked dataset in the field of land survey to support land-use
classification with landscape photos. It has the characteristics of ample
categories, large quantities and low noise. LSPD covers 44 basic land-use
semantics, collected from seven geographical regions of China. And each
category consists of 2000×3 photos, each sample corresponds to three cutting
methods: non cropped photo, rectangularly cropped photo, and masked photo.
After some samples w enhanced, the total sample size is more than 1.4 million,
and the photos contain location information. The LSPD has been successfully
used in the third survey’s photo automatic verification, and the excellent
three-layer structure supports various tasks of resources and environment
classification, such as eco-environment survey, forest resource investigation,
and agricultural natural resources survey.
Land-use Semantic Photo Dataset (LSPD) is a set of semantic samples
of low noise scenes with ample categories, large quantities and high quality
based on the semanteme of land use from 67 million landscape photos of 14
typical counties in 7 geographical regions of China. LSPD covers 44 basic
land-use semantics and fully supports 13 level I land-use categories and 55
level II land-use categories (based on the classification standard of
three-tones) in the Third Land Survey of China.
According to the third survey’s categories, LSPD consists of 1.4 million landscape photos collected from 44 types of scenes. And each category consists of 2000×3 photos, each sample corresponds to three cutting methods: non cropped photo, rectangularly cropped photo, and masked photo. The LSPD has been successfully used in the third survey’s photo automatic verification, and the excellent three-layer system supports various tasks of resources and environment classification, such as eco-environment survey, forest resource investigation, and agricultural natural resources survey.
