rasterio库简介及函数说明 - CSDN博客
Mar 9, 2024 · Rasterio 是一个用于读写栅格数据集的 Python 库,它提供了方便的接口来处理各种栅格数据格式,如 GeoTIFF、JPEG、PNG 等。 Rasterio 能够读取、写入和处理栅格数据,同时还提供了许多空间分析功能。 下面是一个简单的示例,演示了如何使用 Rasterio 打开并读取 GeoTIFF 文件: # 打开 GeoTIFF 文件 with rasterio.open('path_to_your_raster_file.tif') as src: # 读取栅格数据 . raster_data = src.read(1) # 读取第一个波段的数据 # 获取栅格数据的元数据 . …
