plotRoute

Display continuous route in geoplayer figure

Description

example

plotRoute(player,lat,lon) displays a route, as defined by a series of latitude-longitude coordinates, in a geoplayer figure. The route appears as a continuous line on a map. To plot multiple routes in a geoplayer, call plotRoute for each route.

plotRoute(player,lat,lon,Name,Value) uses Name,Value pair arguments to modify the visual style of the route.

For example, plotRoute(player,[45 46],[0 0],'Color','k') plots a route in a geoplayer figure as a black line.

Examples

collapse all

Load a sequence of latitude and longitude coordinates.

data = load('geoRoute.mat');

Create a geographic player and set the zoom level to 12. Compared to the default zoom level, this zoom level zooms the map out by a factor of 8.

player = geoplayer(data.latitude(1),data.longitude(1),12);

Display the full route.

plotRoute(player,data.latitude,data.longitude);

Display the coordinates in a sequence. The circle marker indicates the current position.

for i = 1:length(data.latitude)
    plotPosition(player,data.latitude(i),data.longitude(i));
    pause(0.05)
end

Plot multiple routes in a geographic player by calling plotRoute multiple times.

Load data for a route.

data = load('geoRoute.mat');

Extract data for the first vehicle.

lat1 = data.latitude;
lon1 = data.longitude;

Create a synthetic route for the second vehicle. Add a small offset for better visibility.

lat2 = lat1 + 0.002; % add a small offset in degrees
lon2 = lon1;

Create a geoplayer object, specifying the starting coordinates for one of the routes.

player = geoplayer(lat1(1),lon1(1));

Plot the routes in the geographic player by calling plotRoute for each route.

plotRoute(player,lat1,lon1);
plotRoute(player,lat2,lon2);

Input Arguments

collapse all

Streaming geographic player, specified as a geoplayer object.[1]

Latitude coordinates of points along the route, specified as a real-valued vector with elements in the range [–90, 90].

Data Types: single | double

Longitude coordinates of points along the route, specified as a real-valued vector with elements in the range [–180, 180].

Data Types: single | double

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: 'Color','g'

Line color, specified as the comma-separated pair consisting of 'Color' and a color name, short color name, or RGB triplet. By default, the line color is selected automatically.

For a custom color, specify an RGB triplet. An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range [0,1]; for example, [0.4 0.6 0.7]. Alternatively, you can specify some common colors by name. This table lists the named color options and the equivalent RGB triplet values.

'black''k'[0 0 0]

'white''w'[1 1 1]

Example: 'Color',[1 0 1]

Example: 'Color','m'

Example: 'Color','magenta'

Line width in points, specified as the comma-separated pair consisting of 'LineWidth' and a positive number. 1 point = 1/72 inch.

Display the origin and destination points, specified as the comma-separated pair consisting of 'ShowEndpoints' and 'on' or 'off'. Specify 'on' to display the origin and destination points. The origin marker is white and the destination marker is filled with color.
