Available Data for MazamaSpatialUtils

This document provides documentation for the most important of the available datasets that can be used with MazamaSpatialUtils.

Spatial datasets that have been converted to objects of class \code{simple features data frame} and adhere to the MazamaSpatialUtils standards are considered to be "harmonized".

For reproducibility, the R code that ingests and harmonizes each spatial dataset is included in the package as a \code{convert()} function. Most of the resulting datasets have been been pre-generated and can be downloaded from http://data.mazamascience.com/MazamaSpatialUtils/Spatial_0.7/.

Built in data

MazamaSpatialUtils has three built-in datasets which are included with the package when it is installed. Each of these is a simplified dataset suitable for quick identification of \code{countryCode} or \code{timezone}.

Downloadable data

Running installSpatialData() allows users to install the following pre-generated datasets, which can then be loaded with loadSpatialData(<dataset>)

GACC

Use convertGACC() to download and convert this dataset.

The GACC dataset is a simple features data frame representing the Geographic Area Coordination Center (GACC) boundaries. GACCs are defined as, "The physical location of an interagency, regional operation center for the effective coordination, mobilization and demobilization of emergency management resources."
A coordination center serves federal, state and local wildland fire agencies through logistical coordination of resources throughout the geographic area, and with other geographic areas, as well.

The United States and Alaska are divided into 11 Geographic Areas for the purpose of incident management and mobilization of resources (people, aircraft, ground equipment). Within each Area, an interagency Geographic Area Coordinating Group (GACG), made up of Fire Directors from each of the Federal and State land management agencies from within the Area, is established.

(NOTE: the current geojson download link seems to be dead. A new, shapefile based, link to the data is https://opendata.arcgis.com/datasets/7dc5f4a286bd47e0aaafa0ab05302fe9_0.zip)
