Load a sequence of latitude and longitude coordinates from a driving route.

data = load('geoSequence.mat')

data =struct with fields:latitude: [1000×1 double] longitude: [1000×1 double]

Create a HERE HD Live Map (HERE HDLM) reader from the specified coordinates. If you have not previously set up HERE HDLM credentials, a dialog box prompts you to enter them. The reader contains layered map data for the tile that the driving route is on.

reader = hereHDLMReader(data.latitude,data.longitude);

Read road topology data from theTopologyGeometrylayer. Plot the data.

roadTopology = read(reader,'TopologyGeometry'); plot(roadTopology) legend('Location','northeastoutside')

Overlay the driving route coordinates on the plot.

holdongeoplot(data.latitude,data.longitude,'bo-','DisplayName','Route') holdoff

Zoom in on the route.

latcenter = median(data.latitude); loncenter = median(data.longitude); offset = 0.005; latlim = [latcenter-offset,latcenter+offset]; lonlim = [loncenter-offset,loncenter+offset]; geolimits(latlim,lonlim)

Use the HERE HD Live Map (HERE HDLM) service to read the lane topology data of a driving route and its surrounding area. Plot this data, and then stream the route on a geographic player.

Load the latitude and longitude coordinates of a driving route in Natick, Massachusetts, USA.

route = load('geoSequenceNatickMA.mat'); lat = route.latitude; lon = route.longitude;

Stream the coordinates on a geographic player.

player = geoplayer(lat(1),lon(1),'HistoryDepth',5); plotRoute(player,lat,lon)for(lat) plotPosit idx = 1:长度ion(player,lat(idx),lon(idx))end

Create a HERE HDLM reader from the route coordinates. If you have not previously set up HERE HDLM credentials, a dialog box prompts you to enter them. The reader contains map data for the two map tiles that the route crosses.

reader = hereHDLMReader(lat,lon);

Read lane topology data from theLaneTopologylayer of the map tiles. Plot the lane topology.

laneTopology = read(reader,'LaneTopology'); plot(laneTopology)

Overlay the route data on the plot.

holdongeoplot(lat,lon,'bo-','DisplayName','Route'); holdoff

Overlay the lane topology data on the geographic player. Stream the route again.

plot(laneTopology,'Axes',player.Axes)for(lat) plotPosit idx = 1:长度ion(player,lat(idx),lon(idx))end

Use the HERE HD Live Map (HERE HDLM) web service to read 3-D lane geometry data from a map tile. Then, plot the 2-D part of the data on an OpenStreetMap® basemap.

Create a HERE HDLM reader for a map tile ID representing an area of Berlin, Germany. If you have not previously set up HERE HDLM credentials, a dialog box prompts you to enter them.

tileID = uint32(377894435); reader = hereHDLMReader(tileID);

Add the OpenStreetMap basemap to the list of basemaps available for use with the HERE HDLM service. After you add the basemap, you do not need to add it again in future sessions.

name ='openstreetmap'; url ='https://a.tile.openstreetmap.org/${z}/${x}/${y}.png'; copyright = char(uint8(169)); attribution = copyright +"OpenStreetMap contributors"; addCustomBasemap(name,url,'Attribution',attribution)

Read 3-D lane geometry data from theLaneGeometryPolylinelayer of the map tile. Plot the 2-D part of the lane geometry on theopenstreetmapbasemap.

laneGeometryPolyline = read(reader,'LaneGeometryPolyline'); gx = plot(laneGeometryPolyline); geobasemap(gx,'openstreetmap')

Zoom in on the central coordinate of the map tile.

latcenter = laneGeometryPolyline.TileCenterHere3dCoordinate.Here2dCoordinate(1); loncenter = laneGeometryPolyline.TileCenterHere3dCoordinate.Here2dCoordinate(2); offset = 0.001; latlim = [latcenter-offset,latcenter+offset]; lonlim = [loncenter-offset,loncenter+offset]; geolimits(latlim,lonlim)
