基于高分辨率影像的郴州市主城区多时序矢量道路数据产品(2010、2015、2020、2024年)
收藏资源简介:
本数据产品是基于2010、2015、2020和2024年的郴州市主城区高分遥感影像,通过深度学习道路提取模型处理生成二值图,并矢量化后得到包含道路空间位置、长度、宽度等信息。通过对各景影像进行镶嵌、融合、裁剪得到2m分辨率遥感影像;然后使用基于深度学习算法进行道路提取得到二值图影像;对于已经完成二值化的道路影像,将其导入ArcGIS中,使用ArcScan工具条进行自动化矢量化。再对矢量化之后的道路进行计算几何得到道路长度。
This data product is constructed using high-resolution remote sensing images of the main urban area of Chenzhou City acquired in 2010, 2015, 2020, and 2024. The processing workflow is as follows: first, all individual remote sensing images are mosaicked, fused, and cropped to obtain 2-meter spatial resolution remote sensing imagery; second, a deep learning-based road extraction model is utilized to generate binary road images from the preprocessed remote sensing data; third, these binary road images are imported into ArcGIS, and automated vectorization is performed using the ArcScan toolbar to derive vectorized road features; finally, geometric computations are conducted on the vectorized road data to obtain road lengths, with the final dataset containing comprehensive road information including spatial position, length, and width.
