GeoGridLines
is an option for GeoGraphics that specifies what parallels and meridians to show.
Details


- The following settings can be given for GeoGridLines:
-
None no geo grid lines drawn Automatic geo grid lines placed automatically n approximate number of parallels and meridians Quantity[…] geo grid lines placed at multiples of an angular quantity {latgrid,longrid} geo grid lines specified separately for latitude and longitude - With the Automatic setting, geo grid lines are usually placed at points whose coordinates have the minimum number of digits in their decimal representation.
- For each latitude/longitude coordinate, the following grid line options can be given:
-
None no geo grid lines drawn Automatic geo grid line positions chosen automatically n approximate number of parallels and meridians Quantity[…] geo grid lines placed at multiples of an angular quantity {x1,x2,…} geo grid lines drawn at the specified positions {{x1,style1},…} geo grid lines with specified styles func function to be applied to xmin, xmax to get geo grid line option - When a positive integer n is specified for either latitude or longitude, various heuristics are applied to produce "nice" geo grid lines. As a result, the number of grid lines actually shown may not be exactly n.
- For GeoGridLines->n or GeoGridLines->Automatic, the number of grid lines shown may differ between parallels and meridians.
- For a Quantity specification, only angular quantities are supported.
- The geo grid line function func[xmin,xmax] may return any other geo grid line option.
- AbsoluteOptions can be used to extract explicit lists of latitudes and longitudes that were used for GeoGridLines specifications given Automatic settings.
- Use GeoGridLinesStyle to set styles for geo grid lines.
