MeshiPhi: Earth's digital twin mapped on a non-uniform mesh

Meshiφ (MeshiPhi)

Introducing Meshiφ, a versatile software package designed for comprehensive earth modeling and navigation planning. Meshiφ works by discretizing the Earth's surface into a non-uniform grid, allocating higher resolution in regions of geographic diversity, and conserving lower resolution in more uniform regions. These mesh objects can be output in standard formats, such as GeoJSON and GeoTIFF, enabling data-visualisation via GIS software such as ArcGIS. The default end products are designed to work with PolarRoute.

Installation

Meshiφ can be installed via pip or by cloning the repository from GitHub.

Pip:

pip install meshiphi

Github: (for local development)

git clone https://github.com/bas-amop/MeshiPhi
cd MeshiPhi
pip install -e .

The Meshiφ package has an optional dependency on GDAL, which is required to produce outputs in GeoJSON or GeoTIFF formats. More information on setting up GDAL can be found in the manual pages linked above.

Usage

Meshiφ provides CLI commands. For example, to create a mesh:

create_mesh --config path/to/config.json --output path/to/output.geojson

Example configs are provided in examples/environment_config/.

To export a mesh:

export_mesh --input path/to/meshfile --format geojson --output path/to/output.geojson

For a full list of commands and options, run:

create_mesh --help

See the documentation for more details and advanced usage.

Required Data sources

Meshiφ has been built to work with a variety of open-source atmospheric and oceanographic data sources. A list of supported data sources and their associated data-loaders is given in the 'Data Loaders' section of the manual
