docs: `This button will copy the data from an external dataset into OpenStreetMap. It is only functional in official themes but can be tested in unofficial themes.
|
|
|
|
If you want to import a dataset, make sure that:
|
|
|
|
1. The dataset to import has a suitable license
|
|
2. The community has been informed of the import
|
|
3. All other requirements of the [import guidelines](https://wiki.openstreetmap.org/wiki/Import/Guidelines) have been followed
|
|
|
|
There are also some technicalities in your theme to keep in mind:
|
|
|
|
1. The new point will be added and will flow through the program as any other new point as if it came from OSM.
|
|
This means that there should be a layer which will match the new tags and which will display it.
|
|
2. The original point from your geojson layer will gain the tag '_imported=yes'.
|
|
This should be used to change the appearance or even to hide it (eg by changing the icon size to zero)
|
|
3. There should be a way for the theme to detect previously imported points, even after reloading.
|
|
A reference number to the original dataset is an excellen way to do this
