A minimal Python library to draw customized maps from [OpenStreetMap](https://www.openstreetmap.org/#map=12/11.0733/106.3078) created using the [osmnx](https://github.com/gboeing/osmnx), [matplotlib](https://matplotlib.org/), [shapely](https://shapely.readthedocs.io/en/stable/index.html) and [vsketch](https://github.com/abey79/vsketch) libraries.

Note about NFTs:
|
||||
- I am personally **against** NFTs for their [environmental impact](https://earth.org/nfts-environmental-impact/), the fact that they're a [giant money-laundering pyramid scheme](https://twitter.com/smdiehl/status/1445795667826208770) and the structural incentives they create for [theft](https://twitter.com/NFTtheft) in the open source and generative art communities.
|
||||
- **I do not authorize in any way this project to be used for selling NFTs**, although I have no legal way of enforcing my intent. **Respect the creator**.
|
||||
- The [AeternaCivitas](https://twitter.com/AeternaCivitas) and [geoartnft](twitter.com/geoartnft) projects have used this work to sell NFTs and refused to credit it. See how they reacted after being exposed: [AeternaCivitas](etc/NFT_theft_AeternaCivitas.jpg), [geoartnft](etc/NFT_theft_geoart.jpg).
|
||||
- **I have closed my other generative art projects on Github and won't be sharing new ones as open source to protect me from the NFT community**.

|
||||
|
||||
- **Because of the recent episodes of plagiarism and refusal to credit this project in the NFT Community (Twitter profiles [AeternaCivitas](https://twitter.com/AeternaCivitas) and [geoartnft](twitter.com/geoartnft)) I have decided to change my license to Creative Commons (CC-BY-NC-4.0) which requires you to credit it everytime you use it and forbids you to use if for commercial purposes.**
|
||||
- **The printed message on the figures crediting OpenStreetMap and my repository, included by default, is mandatory.**
|
||||
- **I do not authorize people to sell NFTs using prettymaps and ask that you contact me if you know of someone who is doing it.**
|
||||
Note about crediting:
|
||||
- Please keep the printed message on the figures crediting OpenStreetMap and my repository (The OSM credit is [mandatory by their license](https://www.openstreetmap.org/copyright)).
|

- **CREDIT OPEN SOURCE DEVELOPERS!**
