rsgis

A python package for basic to Advanced GIS operations.

Current_Release

• Metadata support module for landsat
• Landsat module for landsat bands extraction and manipulation

Future_Release

• Metadata support for other file formats(sentinel,NetCDF etc)
• A one liner for basic to advanced GIS operations
• NDVI,NDWI,NDBI
• Image subsetting/clipping support

Installation

The package is available on the python package index(Pypi),to install use the command below;

Python version 3.0 +

      pip install rsgis

Quick_Tutorial

Using the landsat module

     #import the module
    from rsgis import landsat

    #Extract all files
    data = landsat.extract(path/to/landsat/dataset)

    #To check path to extracted data
    data.path

    #Extract specific bands
    #Here we will extract the metadata = 0, band1 = 1 and band2 = 2

    data = landsat.extract(path/to/landsat/dataset, bands = [0, 1, 2])

    #Get metadata path
    data.get_metadata()

    #Get path(s) to specific band(s)
    #In this example, we will be getting band4 and band5
    data.get_bands(4, 5)

Using the Metadata module with the Landsat Module

    #import the class
    from rsgis import Metadata,landsat
    data = landsat.extract(path/to/landsat/dataset)
    meta_path=data.get_metadata()
    mtd=Metadata(meta_path)
    #usage
    mtd.get('SUN') #to get a single parameter. Might return a list of dict if found multiple match. Be specific to avoid this.

    mtd.get_all() #returns a dict of all available parameters in the metadata file

    mtd.get_some(['sun','path','row']) #To get multiple parameters. Returns a list of values.

Command_Line_Use

Change directory into the rsgis folder to run

    python main.py --dir_path [path/to/metadata/file] --get [parametr to get]
    #This command returns the result of the --get query 

Running_The_Tests

Paste a metadata file in the data dir(delete old one) in tests and cd into the test dir then run in terminal

python metadata_test.py 

If no error,then you can go ahead to do some magic.
