threedidepth 0.3

Calculate waterdepths for 3Di results.

threedidepth

Calculate waterdepths for 3Di results.

• Interpolated or gridcell-constant waterlevels

• Interfaces with threediresults via threedigrid

• Progress indicator support

• Low memory consumption

For the interpolated mode, the ‘lizard’-method is used. For a detailed description, read the docstring for the LizardLevelCalculator.

Installation

Make sure GDAL is available as (from osgeo import gdal)

$ pip install threedidepth

Usage

From the cli:

$ threedidepth gridadmin.h5 results_3di.nc dem.tif waterdepth.tif

Or python:

>>> threedidepth.calculate_waterdepth(...)

Development installation with docker-compose

For development, clone the repository and use a docker-compose setup:

$ docker-compose build --build-arg uid=`id -u` --build-arg gid=`id -g` lib
$ docker-compose up --no-start
$ docker-compose start
$ docker-compose exec lib bash

Create a virtualenv:

# note that Dockerfile prepends .venv/bin to $PATH
(docker)$ virtualenv .venv --system-site-packages

Install dependencies & package and run tests:

(docker)$ pip install -r requirements.txt
(docker)$ pip install -e .[test]
(docker)$ pytest

Update packages:

(docker)$ rm -rf .venv
(docker)$ virtualenv .venv --system-site-packages
(docker)$ pip install -e .
(docker)$ pip freeze | grep -v threedidepth > requirements.txt
