TiTiler.PgSTAC is a titiler extension which connect to pgstac STAC database in order to create dynamic mosaics based on Search Query.
Installation
To install from PyPI and run:
# Make sure to have pip up to date
$ python -m pip install -U pip
# Install `psycopg` or `psycopg["binary"]` or `psycopg["c"]`
$ python -m pip install psycopg["binary"]
$ python -m pip install titiler.pgstac
To install from sources and run for development:
$ git clone https://github.com/stac-utils/titiler-pgstac.git
$ cd titiler-pgstac
$ python -m pip install -e .
PgSTAC version
titiler.pgstac depends on pgstac >=0.3.4 (https://github.com/stac-utils/pgstac/blob/main/CHANGELOG.md#v034).
psycopg requirement
titiler.pgstac depends on the psycopg library. Because there are three ways of installing this package (psycopg or , psycopg["c"], psycopg["binary"]), the user must install this separately from titiler.pgstac.
psycopg: no wheel, pure python implementation. It requires thelibpqinstalled in the system.psycopg["binary"]: binary wheel distribution (shipped with libpq) of thepsycopgpackage and is simpler for development. It requires development packages installed on the client machine.psycopg["c"]: a C (faster) implementation of the libpq wrapper. It requires thelibpqinstalled in the system.
psycopg[c] or psycopg are generally recommended for production use.
In titiler.pgstac setup.py, we have added three options to let users choose which psycopg install to use:
pip install titiler.pgstac["psycopg"]: pure pythonpip install titiler.pgstac["psycopg-c"]: use the C wrapper (requires development packages installed on the client machine)pip install titiler.pgstac["psycopg-binary"]: binary wheels
Launch
You'll need to have POSTGRES_USER, POSTGRES_PASS, POSTGRES_DBNAME, POSTGRES_HOST, POSTGRES_PORT variables set in your environment pointing to your Postgres database where pgstac has been installed.
export POSTGRES_USER=username
export POSTGRES_PASS=password
export POSTGRES_DBNAME=postgis
export POSTGRES_HOST=database
export POSTGRES_PORT=5432
$ pip install uvicorn
$ uvicorn titiler.pgstac.main:app --reload
Using Docker
$ git clone https://github.com/stac-utils/titiler-pgstac.git
$ cd titiler-pgstac
$ docker-compose up --build tiler
It runs titiler.pgstac using Gunicorn web server. To run Uvicorn based version:
$ docker-compose up --build tiler-uvicorn
