I'm following along the D3 tutorial, and on this line:
ogr2ogr \ -f GeoJSON \ -where "adm0_a3 IN ('GBR', 'IRL')" \ subunits.json \ ne_10m_admin_0_map_subunits.shp
run into the following problem:
FAILURE: Unable to open datasource 'ne_10m_admin_0_map_subunits.shp' with the following drivers. -> ESRI Shapefile -> MapInfo File -> UK .NTF -> SDTS -> TIGER -> S57 -> DGN -> VRT -> REC -> Memory -> BNA -> CSV -> GML -> GPX -> KML -> GeoJSON -> GMT -> PCIDSK -> XPlane -> AVCBin -> AVCE00 -> DXF -> Geoconcept -> GeoRSS -> GPSTrackMaker -> VFK -> PGDump -> GPSBabel -> SUA -> OpenAir -> PDS -> HTF -> AeronavFAA -> EDIGEO -> SVG -> Idrisi -> ARCGEN -> SEGUKOOA -> SEGY
I have the .shp, .shx, .dbf, and .prj files all in this directory. Why is ogr2ogr unable to read them with anything? (Shapelib is installed.)
I'm using Ubuntu 12.10 if that makes any difference, and had to compile GDAL from scratch, using version 1.9.0.
