Overview

orbis is an R package that offers a suite of tools for simplifying spatial data analysis.

If you find this project useful, please consider giving it a star!

Installation

You can install orbis using the remotes package:

remotes::install_github("danielvartan/orbis")

Usage

orbis is equipped with several functions to help with your analysis, such as:

filter_points_on_land: Filters latitude/longitude points that intersects with a given sf geometry.
get_brazil_municipality: Get Brazilian municipalities data.
get_sidra_by_year: Get and aggregate data by year from SIDRA API (to avoid overloading).
shift_and_rotate: Shift and rotate raster or vector data.
shift and_crop: Shift, rotate, and crop a raster using a vector.
wc_to_ascii: Convert WorldClim GeoTIFF files to ASCII raster format.

Example:

library(dplyr)
library(geodata)
library(orbis)
library(terra)

raster <-
  expand.grid(
    seq(-179.75, 179.75, by = 0.5),
    seq(-89.75, 89.75, by = 0.5)
  ) |>
  as_tibble() |>
  rename(x = Var1, y = Var2) |>
  mutate(value = rnorm(259200)) |>
  rast(type = "xyz") %>%
  `crs<-`("epsg:4326")

world_shape <- world(path = tempdir())
raster <- raster |> crop(world_shape, mask = TRUE)

raster |> plot()

vector <- gadm(country = "rus", level = 0, path = tempdir())

vector |> plot()

raster |>
  shift_and_crop(vector, dx = -45) |>
  plot()
