Couldn't read in Shape file #1

Open ZoeLu90 opened 6 years ago

ZoeLu90 commented 6 years ago

Hi:

I'm following the example of geospatial processing with Julia https://github.com/yeesian/maptime-boston-julia/blob/gh-pages/maptimeboston-julia.ipynb, but I have an error message when I read in the shape file: neighborhoods = GD.read("C:/Users/*********/data/Boston_Neighborhoods.shp") The error message is:

MethodError: Cannot convert an object of type ArchGDAL.IGeometry to an object of type GeoDataFrames.Geometry This may have arisen from a call to the constructor GeoDataFrames.Geometry(...), since type constructors fall back to convert methods.>

What might cause this issue? By the way, are there any other ways to read in shape file in Julia, especially using basemap?

Hi, GeoDataFrames.jl has not been updated with the latest changes to ArchGDAL.jl.

In the meantime, to read and plot a shapefile in julia, you might want to look at the example in https://github.com/JuliaGeo/GeoInterface.jl/pull/12.
