Different map projection

[sverhoeven]

It would be nice if greenland and antartica where smaller.

For example https://openlayers.org/en/latest/examples/projection-and-scale.html

I tried crs in leaflet, see https://leafletjs.com/reference.html#crs . They where not much better.

Alternatives:

• https://openlayers.org/doc/faq.html#what-projection-is-openlayers-using - can use alternative projections but probably the background tiles won't work anymore then.
• https://maplibre.org/ - doesn't seem to have projections either
• https://www.mapbox.com/mapbox-gljs - does have projections but paid after > 50k monthly page loads
• https://cesium.com/platform/cesiumjs/ - display on a globe instead
• https://github.com/d3/d3-geo-projection/ - back to bare d3, less nice out-of-the-box pan/zoom etc but many projections.

Out of these options, only cesium feels like a step forward. Would that be worth the investment?

We could try to make our own crs in leaflet. I only tried the crs's supplied by leaflet.

would that also include reprojecting the map tiles?

I just talked to a colleague, and he said that Robinson is the standard. If you have time, could you have a look? If not, I will check it later.

[Peter9192]

Yeah I also like Robinson, but it's not obvious how to do this with background map tiles.

I wrote an email with you in CC, to Allard Warrink, our visualisation guy at PBL.

Allard is saying this:

Ik heb helaas niet zo snel een oplossing voor map tiles in robinson. Maar jullie kunnen ook overwegen om de wgs84 projectie te gebruiken (EPSG:4326).

Die heeft een stuk minder vervorming op de hogere breedtegraden en is waarschijnlijk wel beschikbaar via carto (ik zag dat daar de baselayer nu vandaan komt…)

Is this useful? I did some browsing, but saw that Carto is a paid website with map tiles. Do you have directions for me, where I can browse through different map tiles styles to find a match with wgs84? Or do you see a quick solution of your own?

[MarkMDekker]

Placed as long run because it seems to be too difficult to do in before version V1.0.
