Web map library/framework

[mvaaltola]

Deciding which web mapping library/framework to use. As the frontend is built on the React web framework, possible React component compatibility also needs to be considered.

Main candidates are:

OpenLayers

Pros:

• Versatile
• Comprehensive documentation

Cons:

• Heavier than leaflet
• Not as easy to use
• React-Openlayers not maintained

Leaflet

Pros:

• Easy to use
• Many plugins to add features
• React-Leaflet seems to be actively maintained (v3 using React hooks is at alpha stage)

Cons:

• Limited base featureset
• Many useful plugins are outdated (such as proj4leaflet and Leaflet.VectorGrid)

This is not directly related to the issue but what do you think @mvaaltola, should we use Typescript insted of Javascript in this project?

[Joonalai]

OpenLayers is chosen as the map framework because:

• supports map rotation
• supports vector tiles natively
• supports multiple CRS's

Lets start with Typescript and fall back to Javascript if needed :)
