# Python functions for a remote sensing application.



## 1. **Raster** : raster utilities, some based on gdal/osgeo bindings

### Functions in `pykic_gdal.py`

- **gdal2array** : read RS dataset from one raw file or from folders --> S2, LS8, maja, sen2cor, wasp. In this case, cloud and no data mask are read.

- **geoinfo** : Extract geo-informations from a raster or a geometry (only epsg for this type)

- **getextent** : Get the extent of a raster

- **array2tif** : Create a compressed raster (.tif) from numpy array (multi-bands / COG format is possible)

- **makemask** : Build a mask array from ogr geometry

- **valfromdot** : Extract values of a raster from coordinates

- **imreproj** : Reproject a raster in memory, without write it on disk

### Functions in `pyfmask.py`

- **applyfmask** : Apply Fmask on Landsat data

### Functions in `resafilter.py`

- **resample_2d** : Make a resampling on image (some methods like lanczos, bicubic etc...)

- **pan_sharpen** : Make a pan-sharpening resampling on a raster



## 2. **Vector** : ogr utilities, mainly based on Geopandas and gdal/osgeo

### Functions in `pykic_ogr.py`

- **ogreproj** : Reprojection of an OGR layer

- **checkproj** : Check if projections between geometries are same OR same as a given epsg

- **zonstat** : Compute zonal statistics (count) on each polygon of layer from an image

- **sprocessing** : Geometric processing between layers (intersection etc...)

- **shpbuf** : Create a buffer of geometries from a layer

- **getbbox** : Get the bounding box of geometry (extent)

- **distm** : Geodesic distance between dots (degrees units)

- **add_field_id** : Add an ID field in the attribute table of a layer

- **convert_coord** : Convert coordinates from an EPSG to another



## 3. **SMAC** : atmospheric correction from smac algorithm, developed by CESBIO

- _smac.py_ : apply atmospheric correction SMAC



## 4. **Miscellaneous** : generic codes to make the job easier

### Functions in `signalproc.py`

- **whittf** : Apply a Whittaker smoothing (weighted if needed)

- **fillnan_and_resample** : Interpolation / resampling of vector data with nan values

- **smooth_compute** : Compute Whittaker smoothing with multi-threading (array with some vector data)

- **regress** : Compute regression from 2 datasets (linear or polynomial)

- **outliers** : Extract index and values of outliers in input

- **phen_met** : Extract phenological metrics from one crop season

### Functions in `database.py`

- **buildproto** : Build a string protocol to get db

- **getdb** : Get data from db

- **getdbtable** : Get list of tables in the database

### Functions in `miscdate.py`

- **datefromstr** : Find a date into a string

- **dconvert** : Convert date format into another

- **dtoday** : Return date of today into a string

### Functions in `plotik.py`

- **imadjust** : Adjust intensity of an image

- **plot_confusion_matrix** : Built the confusion matrix as plot

### Functions in `vi.py`

- Computation of some vegetation index : NDVI, NDWI, EVI, WRDVI, SAVI, CVI
