I want to create an age building map of my home city. I made decision to follow this tutorial: https://www.wired.com/2013/10/how-to-map-building-ages-in-your-home-town/.

Building footprint shapefile for my city was not placed in open sources and I tried to use OpenStreetMap data. Via the OSM Downloader plugin I downloaded the multipolygons, filtered buildings, added required attributes and saved a shapefile.

I uploaded this file to this page to convert it to a Mapbox Studio tileset (a zip archive with files .shp, .shx, .dbf, .prj). I am seeing error Invalid zipfile (and no more information).

I reprojected layer to EPGS:3857, changed type of this layer to tile, converted geometry to the singlepart but this error still showing.

Trying to use other formats (i. e., kml) I get a tileset in Studio but my attributes were deleted.

How to fix this error? I use QGIS 3.8.0 (Zanzibar)

  • What plugin allows you to modify OSM data and download it as a Mapbox Studio tileset?

  • Your workflow doesn't make sense. The OSM Downloader plugin just downloads all OSM data in a given area. You said you first downloaded the data using that plugin, then modified it, then downloaded it (again?) as a Mapbox Studio tileset. Where and how are you downloading it a second time?

  • @csk, drag and drop on this page: studio.mapbox.com/tilesets

    Had a similar problem on Mac. Solved the issue by using WinZip and not the native archiver.

I fixed it. The trouble was in zipper version, default GUI archiver in Ubuntu uses 2.0 version of zip, but Studio requires >2.0. Rezipping via console was helpful.

  • Same here. I had a problem on my macOS Catalina. Default zipper was causing this error. WinZip did the trick.

Update 11/2024: I had a problem with "Invalid Zip File" as well. The issue appeared to be with the default Windows 11 built-in Zip utility.

Solution (for me): Winzip.

Info: the file I was attempting to upload as a tileset was a zipped QGIS Esri shapefile with a polygon geometry. I tried exporting the shape using a variety of QGIS options (exporting as line, adding a map extent, projecting, changing encoding, etc.) and I also tried zipping it using other compression utilities (7-zip, PKzip, etc.). As an aside, I've never had trouble uploading zipped Esri shapefiles from QGIS in the past on Windows 10 OS.
