The goal of lazygeopkg is to provide a lazy, tidyverse style interface to
geopackage format geospatial data. This is identical in concept to lazysf
,
differing in that the SQL engine is provided by DBI, rather than GDAL.
This offers some capabilities, including filtering joins, that aren't possible via GDAL.
You can install the development version of lazygeopkg like so:
devtools::install_github("richardbeare/lazygeopkg")
This is a basic example which shows you how to solve a common problem:
library(lazygeopkg)
ncf <- system.file("gpkg/nc.gpkg", package="sf")
# create a connection object
nc <- connectGPKG(ncf)
nc
# create a lazy table
tbl(nc, "nc.gpkg")
# create a local tibble with interesting names
nicenames <- tibble::tibble(NAME=c("Northampton", "Stokes"))
# load just those rows
tbl(nc, "nc.gpkg") %>%
semi_join(nicenames, copy=TRUE, by = "NAME") %>%
collect()
