openclaw skills install @ruiduobao/geoskill-sentinel1-tile-management模拟Sentinel-1 GRD预处理流水线:线性σ⁰分贝转换(10·log10)、bbox像素对齐裁剪、VV/VH双极化处理与物理区间QA,输出预处理σ⁰(dB) GeoTIFF与含步骤/参数/统计的处理日志JSON。Sentinel-1 GRD preprocessing pipeline: dB conversion, bbox clip, dual-pol QA.
openclaw skills install @ruiduobao/geoskill-sentinel1-tile-managementSimulates the standard preprocessing pipeline for Sentinel-1 GRD (ground range detected, multilooked) imagery:
dB = 10·log10(σ⁰), the logarithmic scale conventional in SAR.--polarization vv,vh): dual-pol for IW, optional for EW.--db-min/--db-max (default −35 to 5 dB).Outputs the preprocessed σ⁰(dB) GeoTIFF plus a processing log JSON (steps, parameters, per-polarization statistics).
