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 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 function. Most of the resulting datasets have been been pre-generated and can be downloaded from http://data.mazamascience.com/MazamaSpatialUtils/Spatial_0.7/.
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 or .

Use convertGACC()
to download and convert this dataset.
The GACC dataset is a SpatialPolygonsDataFrame
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)

to download and convert this dataset.
The GADM dataset is a SpatialPolygonsDataFrame
representing the administrative divisions of a specific country at a specific administrative level. GADM, the Database of Global Administrative Areas, is a high-resolution database of country administrative areas.
NOTE: This script will generate .rda files named GADM_<countryCode>_<admLevel>.rda
and requires user input to specify the country and admin level desired. For example, to generate Admin 1 level boundaries for Belgium, run convertGADM(countryCode = "BE", admLevel = 1
.
This will create GADM_BE_1.rda
. Not all countries have the same number of levels. Many just have two levels while France has five.
Use convertHIFLDFederalLands()
to download and convert this dataset.
The HIFLDFederalLands dataset is a SpatialPolygonsDataFrame
representing the federally owned or administered lands and Indian Reservations of the United States, Puerto Rico, and the US Virgin Islands. Only areas of 640 acres or more are included in this dataset.
Use convertHMSSmoke()
to download and convert this dataset.
The HMSSmoke dataset is a SpatialPolygonsDataFrame
representing the areas of smoke identified for a specific day. This data is derived from analysis of visible satellite imagery obtained during daylight hours.

Use convertStateLegislativeDistricts()
to download and convert this data set.
This creates a SpatialPolygonsDataFrame
for US State Legislative Districts.
User input is required to specify the stateCode
(2-digit ISO 3166) and which house
(Upper or Lower chamber) the data should represent. For example, to obtain data on the Washington State Senate Legislative Districts, run convertStateLegislativeDistricts(stateCode = "WA", house = "Upper")
. This will generate a file named WA_upperHouseLegislativeDistricts.rda
Use convertTMWorldBordersSimple()
to download and convert this data set.
The TMWorldBordersSimple dataset is a simplified version of the TMWorldBorders layer which is useful for spatial searches. Users may wish to use a higher resolution dataset when plotting.
Use convertUSCensusCBSA()
to download and convert this data set.
The USCensusCBSA dataset is a SpatialPolygonsDataFrame
which represents Core Based Statistical Areas (CBSAs) as defined by the Office of Management and Budget (OMB). CBSAs consist of the county or counties or equivalent entities associated with at least one core (urbanized area or urban cluster) of at least 10,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties with the counties associated with the core.
2017 Version

Use convertWBDHUC()
to download and convert this data set.
This creates a SpatialPolygonsDataFrame
that represents a specific level of hydrologic unit from national Watershed Boundary Dataset (WBD). This is a seamless, national dataset which represents the area of the landscape that drains to a portion of the stream network.
User input is required to specify the level
of data to generate. The level
must be one of the following: [2, 4, 6, 8, 10, 12 or 14]. To generate a Level 8 data set, run convertWBDHUC(level = 8)
which will generate a file named WBDHU8.rda
.
Use convertWeatherZones()
to download and convert this data set.
This creates a SpatialPolygonsDataFrame
that represents public zone weather forecast areas. The NWS issues forecasts, and some watches and warnings, for public zones which are usually the same as counties but in many cases are subsets of counties. Counties are subset into smaller zones to allow for more accurate forecasts because of differences in weather within a county due to such things as elevation, or proximity to large bodies of water.
Use convertWorldEEZ()
to download and convert this data set.
This creates a SpatialPolygonsDataFrame
that represents World Exclusive Economic Zones Boundaries. An exclusive economic zone is a sea zone prescribed by the 1982 United Nations Convention on the Law of the Sea over which a state has special rights regarding the exploration and use of marine resources, including energy production from water and wind.
