Choosing a projection for mapnik (based on osm data)

[Chen Barnoy]

Hi all,

I am trying to figure out how to change the output projection of mapnik to EPSG:4326 (geographic wgs84).

I used this tutorial https://switch2osm.org/manually-building-a-tile-server-18-04-lts/ ,

downloaded raw osm data, and used “OpenStreetMap Carto” to create a mapnik stylesheet.

I changed the third row of the stylesheet to: <Map background-color="#aad3df" srs="+init=epsg:4326">

Is that enough to change the output prjection? because the layers in the same stylesheet are defined to the web-mercator projection.

thanks,

Chen
