Taswira

An interactive visualisation tool for GCBM.

Taswira aims to be an easy-to-use utility to help the users of the Generic Carbon Budget Model (GCBM). It takes output generated by GCBM and creates a browser-based UI that allows users to:

• View previews of the spatial data overlaid on an interactive map.
• View graphs of ecosystem indicators from the non-spatial output.
• Visually cycle through the time-series of the spatial output.

Install

Requires Git and Miniconda (or Anaconda) with Python 3.6 or newer.

1. Clone the repository and cd into it:

git clone https://github.com/moja-global/taswira
cd taswira

2. Create a conda environment and activate it:

conda env create -f environment.yml

conda activate taswira

3. Install the Python package:

pip install -e .

Taswira is now installed, see Usage below.

Using Docker

You can also use Taswira through Docker. For that, build a container image:

DOCKER_BUILDKIT=1 docker build -t taswira:latest .

And then use it to run Taswira:

docker run taswira

Usage

usage: taswira [-h] [--allow-unoptimized] config spatial_results db_results

Interactive visualization tool for GCBM

positional arguments:
  config               path to JSON config file
  spatial_results      path to GCBM spatial output directory
  db_results           path to compiled GCBM results database

optional arguments:
  -h, --help           show this help message and exit
  --allow-unoptimized  allow processing unoptimized raster files

NOTE: spatial_results directory should contain GeoTIFFs with filenames that match the pattern {title}_{year}.tiff.

Configuration Schema

config should be a valid JSON file with an array of environment indicator configurations, each of which can have the following keys:

Key	Description	Required
database_indicator	Database column that contains indicator's value	Yes
file_pattern	Pattern that matches to the filenames of the indicator	Yes
palette	A valid colormap string	Yes
title	Human-friendly title of the indicator	No
graph_units	Unit to use in the graph	No

Example config file:

[
  {
    "database_indicator": "NPP",
    "file_pattern": "NPP*.tiff",
    "graph_units": "Ktc",
    "palette": "Greens"
  },
  {
    "database_indicator": "NBP",
    "file_pattern": "NBP*.tiff",
    "palette": "Greens"
  },
  {
    "database_indicator": "NEP",
    "file_pattern": "NEP*.tiff",
    "palette": "Reds"
  },
  {
    "title": "AG Biomass",
    "database_indicator": "Aboveground Biomass",
    "file_pattern": "AG_Biomass_C_*.tiff",
    "palette": "YlGnBu",
    "graph_units": "Mtc"
  }
]
