## Description
The structure of this dataset is:
```bash
.
├── dem_images # 8bit png
├── dem_int16 # 16bit npz files
├── dem_labels # 8bit png with crater visualization
├── labels # crater labels in txt in subfig region
│   ├── circle # circle modeled craters
│   └── ellipse # ellipse modeled craters
└── textures # texture images of craters
```
Each part of subfig is 960x960 resolution extracted from original 61440*184320 DEM image. Each directory has 64 subdirectories standing for 64 row divied from original DEM. Each subdirectory has 192 files standing for 192 columns and each files will be named as "xxx_row_col_960.suffix".

## Download
This dataset can be downloaded as below:

## 数据集说明
本数据集的目录结构如下：
bash
.
├── dem_images # 8位PNG格式文件
├── dem_int16 # 16位NPZ格式文件
├── dem_labels # 带有撞击坑可视化效果的8位PNG格式文件
├── labels # 子图区域内的撞击坑标签文本文件
│ ├── circle # 圆形建模撞击坑
│ └── ellipse # 椭圆形建模撞击坑
└── textures # 撞击坑纹理影像文件

本数据集的每个子图分辨率均为960×960，源自原始61440×184320的数字高程模型影像。数据集的每个目录包含64个子目录，分别对应原始DEM划分出的64行；每个子目录包含192个文件，分别对应192列，所有文件均以"xxx_row_col_960.suffix"格式命名。

## 下载方式
