TiFeatures, pronounced T[ee]Features, is a python package which helps creating lightweight Features server for PostGIS Database. The API has been designed with respect to OGC Features API specification.

Install

$ python -m pip install pip -U
$ python -m pip install tifeatures

# or from source
$ git clone https://github.com/developmentseed/tifeatures.git
$ cd tifeatures
$ python -m pip install -e .

OGC Specification

Specification	Status	link
Part 1: Core	✅	https://docs.ogc.org/is/17-069r4/17-069r4.html
Part 2: CRS by Reference	❌	https://docs.ogc.org/is/18-058r1/18-058r1.html
Part 3: Filtering / CQL2	✅	https://docs.ogc.org/DRAFTS/19-079r1.html

Notes:

The project authors choose not to implement the Part 2 of the specification to avoid the introduction of CRS based GeoJSON. This might change in the future.

While the authors tried to follow the specification (part 1 and 3) to the letter, some API endpoints might have more capabilities (e.g geometry column selection).

PostGIS/PostgreSQL

TiFeatures rely a lot of ST_* PostGIS functions. You need to make sure your PostgreSQL database has PostGIS installed.

SELECT name, default_version,installed_version
FROM pg_available_extensions WHERE name LIKE 'postgis%' or name LIKE 'address%';

CREATE EXTENSION postgis;

Configuration

To be able to work, the application will need access to the database. tifeatures uses starlette's configuration pattern which make use of environment variable and/or .env file to pass variable to the application.

Example of .env file can be found in .env.example

# you need define the DATABASE_URL directly
DATABASE_URL=postgresql://username:password@0.0.0.0:5432/postgis

Launch

$ pip install uvicorn

# Set your postgis database instance URL in the environment
$ export DATABASE_URL=postgresql://username:password@0.0.0.0:5432/postgis
$ uvicorn tifeatures.main:app

# or using Docker

$ docker-compose up
