License: Apache 2.0
Last Commit

A project that generates fast overviews for PANCHROMATIC and MULTISPECTRAL satellite images of a maximum size of 4GB with adaptive color adjustment.

Contributor:Haojun Tang, Yuyang Wu, Jiahao Zhou, Hongbo Pan
Thanks to Sponsor:Hongbo Pan
Central South University


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

Last Commit

A project that generates fast overviews for PANCHROMATIC and MULTISPECTRAL satellite images of a maximum size of 4GB with adaptive color adjustment.

Contributor:Haojun Tang, Yuyang Wu, Jiahao Zhou, Hongbo Pan

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
