我正在研究车辆轨迹的数据集（CSV）。我需要将整个数据集划分为多个部分，每个部分仅覆盖200英尺的距离

我尝试了两点，给出了大约200英尺的距离，并设置为数据框的遮罩。但这并不成立。
sx=16.467;
sy=35.381;
ex=15.64;
ey=238.909;
maskdist=((df['Local X'] > sx) & (df['Local X'] <= ex) & (df['Local Y'] > sy) & (df['Local Y']) <= ey)
dist_df=df.copy()
dist_df=dist_df.loc[maskdist]
要么我必须保留为单独的数据集，要么需要添加一个标记节ID的属性（例如，节1- 0-200ft，2-201-400ft，3-401-600ft ... 10-1800- 2000英尺。）因此，根据区段ID，可以进一步分析数据帧。
