Any idea what GDAL Error 1: Length of input WKB is too small is trying to tell me?
I get this on sf::st_transform() and sf::st_write() operations.
The cause is likely I mistreated my data.
However, I can't interpret the error to avoid it.
My workflow so somewhat like this (non-reproducible pseudocode, sorry):
sf1 <- st_read("shape1.shp")
sf2 <- st_read("shape2.shp")
selectedcols <- names(sf1)[which(names(sf1) %in% names(sf2))]
sf1 %<>% sf1 %>% select(selectedcols)
sf2 %<>% sf2 %>% select(selectedcols)
df1 <- as.data.frame(sf1)
df2 <- as.data.frame(sf2)
allshapes <- rbind(sf1, sf2)
allshapes <- st_sf(allshapes, sf_column_name = "geometry")
identical(st_crs(sf1), st_crs(allshapes)) # should be true!
allshapes <- st_transform(allshapes, crs=25832) # fails
#> OGR: Not enough data
#> Error in CPL_transform(x, crs$proj4string) : OGR error
#> In addition: Warning message:
#> In CPL_transform(x, crs$proj4string) :
#> GDAL Error 1: Length of input WKB is too small
st_write(allshapes, "filename.shp") # fails
# > OGR: Not enough data
# > Error in CPL_write_ogr(obj, dsn, layer, driver, as.character(dataset_options), :
# > OGR error
# > In addition: Warning message:
# > In CPL_write_ogr(obj, dsn, layer, driver, as.character(dataset_options), :
# > GDAL Error 1: Length of input WKB is too small
st_write(allshapes, "filename.gpkg") # fails also
# > OGR: Not enough data
# > Error in CPL_write_ogr(obj, dsn, layer, driver, as.character(dataset_options), :
# > OGR error
# > In addition: Warning message:
# > In CPL_write_ogr(obj, dsn, layer, driver, as.character(dataset_options), :
# > GDAL Error 1: Length of input WKB is too small
plot(allshapes) # works, i.e. geometry is there, attributes are there.
Note: I can't st_join(). I am fairly new to working with spatial data in R, but I am puzzled that all columns (i.e. with suffix .x and .y) are present, while the spatial part of joining throws away a large portion of my data (like: 2/3rds). This is why I opted for the rbind(as.data.frame()) way.
