Hi Cesium community,
I am a newbie to GIS and mapping, and having a lot of fun building a little Cesium app to visualize some data concerning satellite paths. The app needs to work in a completely offline setting, meaning I need all the tiles to be stored locally. The free Natural Earth II tileset, which I believe goes up to tiling level 5, is just fine for the level of resolution needed for this project. But I would really like to have access to political boundaries, waterway names, and things like that. Can anyone suggest a noob-friendly way for me to generate the tileset I need? Even better would be something already created, but I will be happy for whatever help is on offer.
