Saga-GIS toolchain for burned area mapping

Shape of burned area in July 2022 on Kras (Slovenia, Italy) on pre-fire natural RGB

Imagery:

Input imagery are cloud free scenes before and after event. Level 2 data(surface reflectance) is default input. Level 1 can also be used;
the values of L1 are greather: cca: L2sr= 0.8 x L1 and L1= 1.25 x L2sr; so classified grids from L1 data are not in range, but the dynamics are the same and sometimes L2sr are not available in short time after post event so we can use L1 data(also L1...RT); adjusting dNBR threshold for vectorization(ex.:L1 dNBR_th2= 0.137). Using L1 data will not give accurate classes of dNBR; running tool with overridding exports with changed value of dNBR_th2 is recomended to retrive burned area shape.

Importing toolchain into SAGA GIS

Toolchain SAGA-GIS-toolchain_Burned_area.xml can be downloaded from SourceForge or copied at the end of this readme and then droped into SAGA GIS GUI for GUI:

Importing imagery into SAGA GIS:

Geoprocessing-->File -->Satellite Imagery -->Import ... scene _{Tool for Importing Landsat scene(no calibration required), but if Radiometric calibration(radiance) is applied to level 1 data(L1) then Output Data Type should be "floating point numbers")

For Sentinel-2 scenes opening individual bands manualy is advised}

_{Preprocessing is not required, there is an option where Landsat L1 products can be processed to

Top of atmosphere Reflectance with options to apply different DOS(Dark Object Substraction)

methods to get parallel product to surface reflactance

_{- Geoprocessing-->File -->Imagery --> Landsat -->Top of Atmosphere Reflectance}}

Toolchain for Burned area mapping

Inputs

All bands must be in same grid system; ex.: Downscaling SWIR_2 from 20m to 10m resolution

Geoprocessing-->Grid -->Grid System -->Resampling :
Downscaling = Nearest Neighbour; User defined Cell Size = 10m; default(SWIR_2) coordinates; Fit = nodes

- clipping all bands to prebound area

1 - pre fire bands (red, NIR, SWIR_2)
_{Optional(pre) QA_PIXEL input for Landsat imagery}

2 - post fire bands (red, NIR, SWIR_2)
_{Optional(post) QA_PIXEL input for Landsat imagery}

3 - output file name preappendix and postappendix

4 - Thresholds(=th) for dNBR classification and vectorization

Outputs

Indices(pre;post) collection...............pre post (NBR and NDVI and QA_pixel(optional)) 4 or(7) grids
dNBR(Normalized Burn Ratio)
dNBR USGS_classes
dNBR_classes_user_def dNBR_thx
RBR.....................................optional
dNDVI
Vectorized dNBR_th2

QA_pixel export bands(3x) in Indices(pre;post) collection:(pre and post(range 0;1), united(range 0;2), value=0=good pixel

`Scatterplots of clipped indices`

dNBR L2 and dNBR L1 are highly correlated
dNDVI L2 and dNBR L2 are less correlated (NDVI is calculated from bands nearer to VIS spectrum)

The main purpose is assesment of severity and to get trustful shapefile of burned area that can be used for future monitoring(GEE).

dNBR is classified by thresholds(=th) proposed by USGS and user
