Description

Writes Ol.Map object to HTML file.

Usage

ol_map2HTML(ol.map.obj, file.name, page.name = "ROpenLayers Map",
  width = NULL, height = NULL, ol.source.url = NULL,
  nga.olsource = FALSE, map.heading = NULL, map.note = NULL,
  nice.format = FALSE, IE.compatability.view = TRUE)

Arguments

ol.map.obj	Ol.Map object to be exported.
file.name	character output HTML file name.
page.name	character page title to be included in the HTML head section.
width	numeric or character CSS value width of map container.
height	numeric or character CSS value height of map container.
ol.source.url	character string containing the url to the OpenLayers javascript library. Ignored if nga.olsource is TRUE.
nga.olsource	logical. TRUE will use the OpenLayers 3.16.0 javascript library from https://home.gvs.nga.mil (requires authentication); FALSE uses the sources the ol.source.url, if provided, or embeds the OpenLayers 5.3.0 JavaScript code in the HTML head. Only used if ol.source.url is missing or NULL.
map.heading	character heading to be placed over map in html h1 tag.
map.note	character note placed in html paragraph (<p>) tag centered under map container.
nice.format	logical. If TRUE, output file will be formated with new lines and indentation for human readability.
IE.compatability.view	logical. If TRUE, the statement <meta http-equiv="X-UA-Compatible" content="IE=edge"/> to the HTML document head. This statement is required for some browsers to render the map.

Details

Ol.Map object is written to HTML file with embedded javascript. The file will include or source the OpenLayers javascript library as specified in the Ol.Map object (see ol_map). The Javascript will call any REST APIs required for each layer in order to produce an output file with supporting images, if required, that can be placed directly into a directory hosted by a minimal http server.
