Documentation Help Center. You can add a map to your layout in the Simulation Data Inspector to view routes of longitude and latitude data. The map data is synchronized with signal data in the Simulation Data Inspector, allowing you to analyze signal activity throughout the route. To analyze the relationship between the route and signal values, you can replay the data. When you replay data in the Simulation Data Inspector, synchronized cursors and markers move across the plots in the view. If your model includes latitude and longitude signals, you can log data to the Simulation Data Inspector and visualize it during simulation. You can also import the data from the workspace or a file using the instructions in View Data from the Workspace or a File or the Simulink. For this example, import a file of recorded map and speed data using Simulink. Then, open the Simulation Data Inspector. Configure the plot area in a 2x1 layout so you can view the speed data and map data together. To plot the speed data on the lower plot, select the plot and then select the check box next to the speed signal. From the visualization gallery, drag a map onto the top subplot in the layout. You can also plot map data by selecting multiple signals while holding Ctrl and then dragging those signals onto the map. The menu in the lower-right shows drop-downs you can use to specify which signal to use for the latitude data and which to use for the longitude data. You can add cursors to the plots to analyze the relationship between the speed signal and the route shown on the map. To add two cursors to the layout, click the drop-down arrow on the cursors button in the toolbar and select Two Cursors. Move the cursor on the left. The marker on the right of the map moves as you move the left cursor because the route starts in Boston and moves East to West with time. You can replay data in the Simulation Data Inspector to automate moving cursors across the visualizations in your view. Then, press the Replay button. A data marker on the map and a cursor on the time plot sweep synchronously across the screen. The synchronous replay facilitates an intuitive understanding of the relationship between speed and position throughout the trip. By default, the Simulation Data Inspector replays data at one second per second, meaning that the cursor moves through one second of data in one second of clock time. The data for this trip spans approximately 34 minutes. You can increase the replay speed using the arrow to the right of the label or by clicking the label and typing the desired speed. Increase the replay speed to 32x using the arrow. View Data with the Simulation Data Inspector. Choose a web site to get translated content where available and see local events and offers.

Documentation Help Center. This example shows how to create a range of different maps using mapshow. Display a geographic data structure array with lines representing roads. The point coordinates in the shapefile are in meters. Therefore, we need to convert the placename coordinates from meters to survey feet in order to overlay the points on the image. Note that islands are visible in the orthophoto through three "holes" in the pond polygon. Display roads in the same figure. View the Mount Washington terrain data as a mesh. View the Mount Washington terrain data as a 3-D surface. Use the default 3-D view, which shows how the range looks from the southwest. Read the terrain data files for Mount Washington and Mount Dartmouth. To plot the data using mapshowthe raster data must be of type single or double. Specify the data type for the raster using the 'OutputType' name-value pair. Ensure the contour lines and labels appear over the terrain data by specifying the 'ZData' name-value pair as a matrix of zeros. Apply a colormap appropriate for terrain data using demcmap.

Documentation Help Center. Use the Map Viewer to view geospatial data in map x-y coordinates. The Map Viewer works with vector, image, and raster data grids in a map coordinate system. You can load data, pan and zoom on the map, control the map scale of your screen display, control the order, visibility, and symbolization of map layers, annotate your map, and click to learn more about individual vector features. For usage information, see the following sections. The Map Viewer opens with no data loaded and an empty map display window. The first step is to import a data set. This option imports the data into the viewer but does not add it to your workspace. To view standard-format geodata files provided with the toolbox, set your working folder or navigate the Map Viewer Open dialog to. If the image type is truecolor RGBspecify which band represents the red, green, and blue intensities. The RasterInterpretation of the referencing object must be 'cells'. Data grids. Vector data. The X and Y variables can specify multiple line segments or multiple polygons if they contain NaN s at matching locations in the coordinate vectors. Vector geographic data structure. Once you import your first data set, the Map Viewer automatically sets the limits of its map display window to the spatial extent of the imported data. As you move any of the Map Viewer cursors across the map display area, the coordinate readout in the lower left corners shows you the cursor position in map X and Y coordinates. The Map Viewer requires that all currently viewed data sets possess the same coordinate system and length units. This is likely to be the case for data sets that originated from a common source. If it is not the case, you will need to adjust coordinates before importing data into the Map Viewer. If some or all of your data is in geographic coordinates, use projfwd or mfwdtran to project latitudes and longitudes to your desired map coordinate system before you import it. When starting from a different projection, you must first unproject to latitude and longitude using projinv or minvtranthen reproject with projfwd or mfwdtran. If you simply need a change of units, multiply by the appropriate conversion factor obtained from unitsratio. Geographic coordinates must be consistently expressed in either degrees or radians not both at once. When using geographic coordinates, do not specify the viewer's map units see below ; you can only use the Map Viewer's map scale display when working in linear units of length. If you tell the Map Viewer which length unit you are using, it can calculate an approximate map scale for your onscreen display. Set the map units with either the drop-down menu at the bottom of the display or the Set Map Units item in the Tools menu.

Documentation Help Center. Two-element array — The values are the azimuth and elevation angles respectively. Three-element array — The values are the x - y - and z -coordinates of a vector that starts at the center of the plot box and points toward the camera. Specify dim as 2 for the default 2-D view or 3 for the default 3-D view. Specify input arguments from any of the previous syntaxes to get the angles for the new line of sight. Or, specify no input arguments to get the angles for the current line of sight. Use the peaks function to get the x - y - and z -coordinates of a surface. Then plot the surface and label each axis. View the plot using an azimuth of 90 degrees and an elevation of 0 degrees. The new line of sight is along the x -axis. Create a set of x - y - and z -coordinates and use them to plot a surface. Then label each axis. Change the view by specifying v as the x - y - and z -coordinates of a vector, and return the new azimuth and elevation angles. The new angles are based on a unit vector pointing in the same direction as v. Starting in Rb, you can display a tiling of plots using the tiledlayout and nexttile functions. Call the tiledlayout function to create a 1-by-2 tiled chart layout. Call the nexttile function to create the axes objects ax1 and ax2. Use them to create separate but identical line plots. Change the view of the right plot to a side view along the x -axis. Azimuth, specified as an angle in degrees from the negative y -axis. Increasing this angle corresponds to counterclockwise rotation about the z -axis when viewing the x - y plane from above. The default value depends on whether your chart is in a 2-D or 3-D view. For 2-D charts, the default value is 0. For 3-D charts, the default value is

Make sure to format your text in the standard way 1: Nwhere N is a positive number such that a distance on the ground is N times the same distance on your screen, e. It is also approximate if your projection introduces significant distortion. If your data falls in a fairly small area and you use a conformal projection e. By default, the Map Viewer sets the limits of your map window to match the extent of the first data set that you load. You will probably want to adjust this to see some areas in greater detail. The Map Viewer provides several tools to control the limits of your map window and the map scale of the data display.
