Hi Hernan I downloaded this shapefile directly via the browser. Indeed it wonât load, the type of shape file returned is self longAt: 33 bigEndian: false -> 577660194 where it should have answered an Integer between 0 and 31 shapeType "position 32, Integer between 0 and 31, Little Endian" ^shpBytes longAt: 33 bigEndian: false No idea what could be the cause â apparently the header of the file (the first 100 bytes) is not ok... Hans You mean some types are missing? Because I get this error when I try to read some SHP files: "Types > 20 are not yet accounted for" I wrote this script to reproduce: | shpE legend urlRoot urlESRIFilePrefix urlESRIFileShp urlPath response fileRef | " Download Shapefile resources " urlRoot := 'https://github.com/nvkelso/natural-earth-vector/blob/master/110m_cultural/'. urlESRIFilePrefix := 'ne_110m_populated_places'. urlESRIFileShp := urlESRIFilePrefix , '.shp'. urlPath := urlRoot , urlESRIFilePrefix. #('.shx' '.dbf' '.shp') do: [ : ext | | url | url := (urlPath , ext , '?raw=true') asZnUrl. (response := ZnEasy get: url) isSuccess ifFalse: [ self error: 'Cannot download file' ]. fileRef := FileSystem disk workingDirectory / (urlESRIFilePrefix , ext). fileRef writeStreamDo: [ : stream | stream nextPutAll: ((ZnByteEncoder newForEncoding: 'koi8r') decodeBytes: response contents ) ] ]. Once downloaded: | urlESRIFilePrefix urlESRIFileShp shpE | urlESRIFilePrefix := 'ne_110m_populated_places'. urlESRIFileShp := urlESRIFilePrefix , '.shp'. " Load and display it in Morphic " shpE := ShapeEnsemble fromFile: urlESRIFileShp. Maybe it's related with the fact they are encoded as koi8r? I checked with Zinc downloading first from the browser: | shpFile | shpFile := 'ne_110m_admin_0_countries.shp' asFileReference. [ shpFile binaryReadStreamDo: [ : in | (ZnCharacterEncoder detectEncoding: in upToEnd) identifier ] ] on: ZnCharacterEncodingError do: [ nil ]. Cheers, Hernán
