YAML OGR Templating (yogrt) 🍦

A simple templating tool for importing GIS data to PostGIS

Requirements

• Python 3.6+
• GDAL & OGR
• awscli (optional)
• poetry (optional)

Installation

poetry:

poetry add git+ssh://git@github.com/Anagraph/yogrt.git@develop
poetry shell

Example

Initialize template files

export YOGRT_TARGET_DIR=./yogrt
mkdir -p $YOGRT_TARGET_DIR
yogrt init --target-directory $YOGRT_TARGET_DIR

You will now have the following files within the target directory:

.
├── profile.yaml
├── secrets.yaml
└── sources.yaml

You can modify the target projection of the sources by modifying the profile.yaml file.

You must modify the secrets.yaml to configure it with your database and optionally your AWS credentials.

The sources.yaml file is where you will configure the sources you want to import:

countries:
  type: polygon
  download_url: https://datahub.io/core/geo-countries/r/countries.geojson
  table_name: countries

ldc:
  type: polygon
  download_url: https://www.oeb.ca/documents/opendata/open-data-electricity-map-20220131.zip
  table_name: ldc
  is_zip: true
  unzip_filename: "Electric_220131.kmz"

Import datasources

Run with:

yogrt run --profile=$YOGRT_TARGET_DIR/profile.yaml --sources=$YOGRT_TARGET_DIR/sources.yaml  --secrets=$YOGRT_TARGET_DIR/secrets.yaml
