HYDrologic Remote sensing Analysis for Floods
Project description
hydra-floods
Introduction
HYDrologic Remote sensing Analysis for Floods (HydraFloods) is a Python application for downloading, processing, and delivering flood maps derived from remote sensing data. This is backend behind the HYDRAViewer Geospatial tool which utilizes many remote sesnsing dataset as possible to provide daily (sometime twice daily) flood maps.
Installation
- Create a new conda environment with the required dependencies and activate the environment
$ conda create -n hydra -c conda-forge python=3.6 numpy scipy pandas requests yaml xmltodict gdal shapely pyproj netCDF4 xarray pyresample geopandas earthengine-api fire
$ conda activate hydra
- Install additional packages via
pipthat are not on conda-forge
$ pip install git+git://github.com/KMarkert/simple-cmr.git
- Authenticate the Earth Engine API
$ earthengine authenticate
- Install Google Storage Utility command-line interface (gsutil) and the setup the
gsutilenvironment
$ gcloud init
$ gcloud auth application-default login
NOTE:
Make sure your initialize the ee and gsutil APIs with Google accounts that have permissions to read and write to Google Cloud Storage and Google Earth Engine assets.
- Download the hydrafloods source code and install the package
- COMING SOON: the hydrafloods package will be on PyPI in the near future to prevent installing from source
$ git clone https://github.com/servir-mekong/hydra-floods.git
$ cd hydra-floods/py pkg
$ python setup.py install
- Test to see if the installation was successful
$ hydrafloods run_tests
How-to
To initiate the HydraFloods process use the command below.
$hydrafloods process atms 2015-07-19 --configuration myconf.yaml
NOTE: Details regarding the command
-
hydrafloods --- call the hydrafloods process to begin
-
process --- start the hydraflood process
-
atms --- specify sensor (see processing.py for details options include: Sentinel2, Landsat, Modis, Viirs, Atms, Sentinel1)
-
2015-07-19 --- specify the date of intrest
-
--configuration --- use the configuration file
-
myconf.yaml --- call the .yaml file that specifies the ROI etc. (see the exampl.yaml for details)
