The webmap package in R is a tool that leverages the JavaScript Leaflet library to create dynamic web maps. It includes base layers from The National Map (TNM), which provides access to geospatial information about the landscape of the United States and its territories. However, it is important to note that base layers outside these areas are unavailable at higher spatial scales. While TNM services are consistently monitored for reliability, their availability outside of standard government working hours cannot be guaranteed. The webmap package is designed to work in conjunction with the Leaflet for R package. Furthermore, it comes equipped with a variety of utility functions that enable you to enhance your web map with additional features.
To install the current release of the package from CRAN you can use the following command in R:
To install the package along with its dependencies, which are required to run examples in the package help documentation, run:
To install the development version of the package, you need to clone the repository and build from source, or run the following commands:
if (!requireNamespace("remotes")) install.packages("remotes")
remotes::install_gitlab(
repo = "inl/webmap@develop",
auth_token = Sys.getenv("GITLAB_PAT"),
host = "code.usgs.gov",
dependencies = TRUE
)After installing the package, you can use it in various contexts, including the R console, R Markdown documents, and Shiny applications.
To create the default web map and display it (the screenshot below showns the default web map), you can run the following commands:
The screenshot below shows the default web map that is created by the above commands.
