To make folder structure mbtile you might need to add ''-e'' in the recipe.
or tile is made you can use Mbutil to create folder structure from single file. To your second query to create building footprints with rater tiles there are two ways two approach it. You can create raster tiles from geotiff by using tiles2py in folder structure. But in your case you can use Tileserver-gl what it does is it can host vector tiles but serve them as raster. You can check config file and change as per your requirements such as 256x256 or 512x512. let me know if you still face issue. Note - Go by vector tiles its fast and you can give 3D effect as you have seen in our app. Thanks and Regards On Thu, 26 May, 2022, 6:39 pm Nikhil VJ, <nikhil...@gmail.com> wrote: > Hi Deepak, > > Thanks for the suggestion. > > I came across tippecanoe again : https://github.com/mapbox/tippecanoe > and finally seeing a use case for it.
