Data

The satellite data is from LargeSatelliteImgs Dataset, which is a dataset of different kinds (Panchromatic and Multispectral) of GeoTIFF Satellite Images in a variety of formats (UINT8, UINT16, FLOAT32) and scales (from 400MB to 4GB).

Usage

In config file:

config.yaml
├── data
│   ├── filename: string
│   └── stretch: enum
│          - linear
│          - log
│          - gamma
│          - tile_stretch
│          - piecewise_equal
│          - histo_equal
└── output
    ├── imgtype: enum
    │       - PNG
    ├── filename: string
    ├── width: int
    ├── height: int
    ├── band1: int
    ├── band2: int
    └── band3: int
