geospatial-lambda

This service aims to provide Geospatial Functionality on top of RDS PostgreSQL/PostGIS. The API provides basic discovery endpoint on top of registered geospatial layers as well as intersect endpoint for intersect given Lat, Lon specific layer defined by name

Setup

The team recommends installing Homebrew or another package manager if possible for easier installation and upgrade management.

Environment setup

This is a python application and it needs the following tools installed:

• python3
• virtualenv

These tools can be installed via homebrew and pip:

$ brew update
$ brew install [email protected]
$ pip3 install virtualenv

The repository is located at risk-stream-service and can be checked out using git.

$ git clone [email protected]:cytora/risk-stream-service.git

To configure the service several environment variables must be set. The env.example.sh file that contains the names of the variables and a brief description of how the variables are used. To configure your local environment please copy the example file and fill the variable marked with __EMPTY__. To facilitate the creation of the most common configurations a env.sh file can be downloaded from 1pass stored under the key risk stream dev configurations.

$ cp env.example.sh env.sh # copy the content of the 1pass entry into the new file
$ # alternatively download the pre-filled file from 1pass (see above)
$ source env.sh # this will load the variables into your shell's environment

The first time the project is executed a virtualenv should be created and the project's dependencies must be installed:

$ virtualenv venv                 # creates the virtualenv
$ source venv/bin/activate        # activates it
$ pip install -r requirements.txt # install the dependencies

NOTE: before installing requirements.txt, if you are on a Mac replace 'python-magic' -> 'python-magic-bin' in that file

Now we should be able to start the service locally.

$ python local.py
$ open http://localhost:8080 # opens a browser window
