Equirectangular Tiles supported?

Closed this issue · 3 comments

Hey!
Is it possible to display equirectangular raster tiles with harp.gl, i.e. tiles where there are two quadratic tiles on level 0?
I saw harp.gl supports equirectangular projection and various tiling schemes but wasn't able to produce a working example.
Thanks in advance!

@pwambach , Yes, we have an equirectangular projection.

See:

harp.gl/@here/harp-geoutils/lib/tiling/HereTilingScheme.ts

Line 17 in d7e7b67

export const hereTilingScheme = new TilingScheme(

And specifically the subdivisionScheme, does that suit you. If not, you can create your own class which implements the SubdivisionScheme scheme, and pass it to the MapView.

Thanks for your fast answer!

Do I have to create my own DataSource class to use a different tiling scheme? I tried with a little debug example using the WebTileDataSource and it doesn't seem to have any effect.

Here is my example: https://jsfiddle.net/xeucz93d
