***General Introduction***
This dataset contains the training and testing set collected	 during optimizing 
multi-resolution topographic indicator combinations reserach.
As part of Si Alu's research project, it is being made public both to act as 
fundamantal dataset for publications and in order for other researchers to use this 
data in their own work.


***Purpose of the test campaign***

The purpose of these experiments was to analyzed the influence of pixel resolutions 
on susceptibility assessment performance, and aimed to identify the optimal pixel 
resolution combination for topographic indicators.


***Description of the data in this data set***
The dataset contains the basic training and testing sets used in this study to 
assess debris flow susceptibility.

Each dataset contains 77 attribute columns, where the "disaster" attribute indicates 
whether an area experienced a debris flow (1 denotes debris flow occurrence, 
0 denotes no occurrence). The remaining columns represent attribute values 
extracted from various raster datasets (ALT, SLP, CUR, RAI, SCI, ECV, TWI, SPI, DRN) 
at resolutions of 2.5m, 5m, 7.5m, 10m, 12.5m, 15m, 17.5m, and 20m. 

Among them:
dem represent ALT indicator
slp represent SLP indicator
cur represent CUR indicator
dxqfd represent RAI indicator
dbqgd represent SCI indicator
gcbyxs represent ECV indicator
twi represent TWI indicator
spi represent SPI indicator
dis represent DRN indicator

2 represent 2.5m resolution
5 represent 5m resolution
7 represent 7.5m resolution
10 represent 10m resolution
12 represent 12.5m resolution
15 represent 15m resolution
17 represent 17.5m resolution
20 represent 20m resolution
