YESeg-OPT-SAR

Introduction

YESeg-OPT-SAR is a sufficiently annotated high-resolution remote sensing dataset for land use classification, which combines high-resolution RGB optical images with SAR images at a resolution of 0.5 meters.

Details

YESeg-OPT-SAR uses high-resolution optical and SAR images from Google Earth L18 products imaged during 2010/10/21-2016/8/25 with a spatial resolution of 0.5 m.
It contains 2231 pairs of images of the same area with a size of 256×256. The dataset contains two study areas, one covers an area in the longitude range of 122.836°E-122.869°E and the latitude range of 45.105°N-45.133°N, and the other with a longitude range of 110.135°E-110.160°E and latitude range of 34.593°N-34.626°N,which covering a wide range of different terrain and vegetation.The location of the study area is shown on the map below.
The images in the dataset are fully labeled with pixel-level categories, including background, bare ground, vegetation, trees, houses, water, roads, and others, where the label values and category percentages are shown in the table below.

Label	Name	Percent(%)
0	background	2.26
1	bare ground	55.84
2	low vegetation	26.55
3	trees	5.29
4	houses	4.39
5	water	1.69
6	roads	3.88
7	other	0.11
