check.layers_navigation: Check Layers

In bbest/ohigui: Ocean Health Index - Graphical User Interface

Description

Check all the input layers as defined by layers_navigation.csv, found in dir.layers and assembled out to a consolidated layers_data.csv for easy data extraction.

Usage

  check.layers_navigation(layers_navigation.csv,
    layers_id_fields, verbose = T, msg.indent = "  ")

Arguments

layers_navigation.csv	Full path to the layers_navigation.csv file.
dir.layers	Full path to the directory containing the layers files.
layers_data.csv	Combined data table output of all layers dir.layers based on descriptions in layers_navigation.
layers_id_fields	Character vector of unique identifiers typically spatial (eg region_id, country_id, saup_id).

Value

All of these parameters should be defined in config.R.

The check.layers_navigation() function iterates through the layers_navigation.csv and checks for the existence of all the input files and looks for matching fields. Any unused fields should be dealt with before moving onto using assemble.layers_data.

The assemble.layers_data() function reads in all data layers and combines them into a single data table layers_data.csv.

  assemble.layers_data(layers_navigation.csv, dir.layers, layers_data.csv, layers_id_fields)
