Simple Python GIS Web Services
- Create `mapshader.MapSource` objects and render them as geojson, tiles, or images
- This project should still be considered experimental
```bash
pip install mapshader
```
#### Setup Mapshader Conda Environment
```bash
conda create -n mapshader python=3.8
conda activate mapshader
git clone [email protected]:makepath/mapshader.git
cd mapshader
pip install -e .
```
#### Run Tests
```bash
conda activate mapshader
pytest mapshader/tests -sv
```
#### Run Flask Server
```bash
conda activate mapshader
mapshader serve
>>> * Serving Flask app "flask_app" (lazy loading)
>>> * Environment: production
>>> WARNING: This is a development server. Do not use it in a production deployment.
>>> Use a production WSGI server instead.
>>> * Debug mode: on
>>> * Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
>>> * Restarting with stat
```
#### Mapshader Config (YAML)
While mapshader comes with default services to help with testing, users can create their own services
via YAML.
*my_services.yaml*
```bash
---
metadata:
version: 1
sources:
- name: Global Elevation Example
key: elevation-example
text: Elevation
description: Global elevation example

- 248
raster_padding: 0
raster_interpolate: linear
xfield: geometry
yfield: geometry
filepath: mapshader/tests/fixtures/elevation.tif
transforms:
- name: squeeze

args:

```
This configuration file can then be passed to the flask server upon startup:
```bash
conda activate mapshader
mapshader serve my_services.yaml
>>> * Serving Flask app "flask_app" (lazy loading)
>>> * Environment: production
>>> WARNING: This is a development server. Do not use it in a production deployment.
>>> Use a production WSGI server instead.
>>> * Debug mode: on
>>> * Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
>>> * Restarting with stat
