# MapComplete
|
||
|
|
|
||
|
|
MapComplete attempts to be a webversion of StreetComplete.
|
||
|
|
|
||
|
|
The design goals of MapComplete are to be:
|
||
|
|
|
||
|
|
- Easy to use
|
||
|
|
- Easy to deploy
|
||
|
|
- Easy to modify
|
||
|
|
|
||
|
|
The basic functionality is to download some map features with overpass and then ask certain questions. An answer is sent back to OpenStreetMap.
|
||
|
|
|
||
|
|
Furthermore, it shows images present in the `image` tag or, if a `wikidata` or `wikimedia_commons`-tag is present, it follows those to get these images too

## License

GPL + pingback.
|

|
|
|
||
|
|
I love it to see where the project ends up. You are free to reuse the software (under GPL) but, when you have made your own change and are using it, I would like to know about it. Drop me a line, give a pingback in the issues, ...

## Dev
|
||
|
|
|
||
|
|
To develop:
|
||
|
|
|
||
|
|
1. Install `npm`.
|
||
|
|
2. Run `npm install` to install the dependencies
|
||
|
|
3. Run `npm run start` to build and host a local testversion
|
||
|
|
|
||
|
|
To deploy:
|
||
|
|
|
||
|
|
0. `rm -rf dist/` to remove the local build
|
||
|
|
1. `npm run build`
|
||
|
|
2. copy the entire `dist` folder to where you host your website. Visiting `index.html` gives you the website

## Architecture
|
||
|
|
|
||
|
|
### High-level overview
|
||
|
|
|
||
|
|
The website is purely static. This means that there is no database here, nor one is needed as all the data is kept in OpenStreetMap or Wikimedia (for images).
|
||
|
|
|
||
|
|
When viewing, the data is loaded from overpass. The data is then converted (in the browser) to geojson, which is rendered by Leaflet.
|
||
|
|
|
||
|
|
When a map feature is clicked, a popup shows the information, images and questions that are relevant for that object.
|
||
|
|
The answers given by the user are sent (after a few seconds) to OpenStreetMap directly - if the user is logged in. If not logged in, the user is prompted to do so.
