endow

The package simplifies data collection and data processing pipelines for the ENDOW project. The code can be re-used to collect a series of gespatial variables for a given point on Earth.

Installation

You can install the development version of endow from GitHub with:

# install.packages("devtools")
devtools::install_github("barguzin/endow")

Example

Endow package provides a series of utility functions to simplify data collection. Typically, the pipeline is set in a following way:

flowchart LR
    pnt[sf object]
    buff[buffer]
    rast[global raster]
    site[site location]
    crop[cropped raster]
    summ[.csv]
    repo[site <br> reports]

    site--site_id, lon, lat---pnt--dist---buff--aggregate---summ

    rast--crop--> crop
    buff--crop--> crop
    crop--aggregate-->summ
    summ-->repo

library(endow)

## basic example code
# create a point
my_point = endow::make_point("site A", lon=45, lat=45)

# create a buffer 
my_buffer = endow::make_buffer(my_point, dist=5000) # dist in meters 

# the file containing site names and their coordinates
df = read.csv(path_to_file) 

# the global raster file that will be cropped 
pop2000 = 'file/path/to/raster.tiff'

# apply the function from endow with params
mapply(endow::collector, pop2000, 'dir/to/save/processed', 
       year=2000, 
       year_var = df$start, 
       site_id = df$end, 
       lon=df$lng, lat=df$lat, dist=5000, 
       var_name='raster_var')
