Plot propagation data on map

Description

plot(pd) plots the propagation data on a map. Each data point is displayed as a circular marker that is colored according to the corresponding value.

example

plot(___,Name,Value) plots the propagation data with additional options specified by name-value pair arguments.

Launch Site Viewer with basemaps and building files for Manhattan. For more information about the osm file, see [1].

viewer = siteviewer("Basemap","streets_dark",...
        "Buildings","manhattan.osm");

Show a transmitter site on a building.

tx = txsite("Latitude",40.7107,...
        "Longitude",-74.0114,...
        "AntennaHeight",80);
show(tx)

Create receiver sites along nearby streets.

latitude = [linspace(40.7088, 40.71416, 50), ...
        linspace(40.71416, 40.715505, 25), ...
        linspace(40.715505, 40.7133, 25), ...
        linspace(40.7133, 40.7143, 25)]';
longitude = [linspace(-74.0108, -74.00627, 50), ...
        linspace(-74.00627 ,-74.0092, 25), ...
        linspace(-74.0092, -74.0110, 25), ...
        linspace(-74.0110, -74.0132, 25)]';
rxs = rxsite("Latitude", latitude, "Longitude", longitude);

Compute signal strength at each receiver location.

signalStrength = sigstrength(rxs, tx)';

Create a propagationData object to hold computed signal strength data.

tbl = table(latitude, longitude, signalStrength);
pd = propagationData(tbl);

Plot the signal strength data on a map as colored points.

legendTitle = "Signal" + newline + "Strength" + newline + "(dB)";
plot(pd, "LegendTitle", legendTitle, "Colormap", parula);

Input Arguments

collapse all

Propagation data, specified as a propagationData object.

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: 'Type','power'

Data variable to plot, specified as the comma-separated pair consisting of 'DataVariableName' and a character vector or a string scalar corresponding to a variable name in the data table used to create the propagation data container object pd. The default value is dynamic and corresponds to the DataVariableName property of the propagationData object.

Data Types: char | string

Type of value to plot, specified as the comma-separated pair consisting of 'Type' and one of the values in the Type column:

TypeColorLimitsLegendTitle
'custom'[min(Data) max(Data)]''
'power'[-120 -5]'Power (dBm)'
'efield'[20 135]'E-field (dBuV/m)'
'sinr'[-5 20]'SINR (dB)'
'pathloss'[45 160]'Path loss (dB)'

The default value for Levels is a linearly spaced vector bounded by ColorLimits.

Data Types: char | string

Data value levels to plot, specified as the comma-separated pair consisting of 'Levels' and a numeric vector. The propagation data is binned according to Levels. The data in each bin is color coded according to the corresponding level. The colors are selected using Colors if specified, or else Colormap and ColorLimits. Data points with values below the minimum level are not included in the plot.

The default value for Levels is a linearly spaced vector bounded by ColorLimits.

Data Types: double

Colors of the data points, specified as the comma-separated pair consisting of 'Colors' and an M-by-3 array of RGB (red, blue, green) or an array of strings, or a cell array of character vectors. Colors are assigned element-wise to values in Levels for coloring the corresponding points. Colors cannot be used with Colormap and ColorLimits.

Data Types: double | char | string

Colormap for the coloring points, specified as the comma-separated pair consisting of 'Colormap' and a predefined colormap name or an M-by-3 array of RGB (red, blue, green) triplets that define M individual colors. Colormap cannot be used with Colors.

Data Types: double | char | string

Color limits for the colormap, specified as the comma-separated pair consisting of 'ColorLimits' and a two-element vector of the form [min max]. The color limits indicate the data level values that map to the first and last colors in the colormap. ColorLimits cannot be used with Colors.

Data Types: double

Size of data markers plotted on the map, specified as the comma-separated pair consisting of 'MarkerSize' and a positive numeric scalar in pixels.

Data Types: double

Show color legend on map, specified as the comma-separated pair consisting of 'ShowLegend' and true or false.

Data Types: logical

Title of color legend, specified as the comma-separated pair consisting of 'LegendTitle' and a character vector or a string scalar.

Data Types: string | char

Map for surface data, specified as the comma-separated pair consisting of 'Map' and a siteviewer object.[1] The default value is the current Site Viewer or a new Site Viewer, if none is open.

Data Types: char | string
