Site Viewer

Introduction

Transmitter and receiver site for RF propagation visualization involves a map display called Site Viewer. You can use the Home button to view the default home location of Site Viewer.

Site Viewer includes in-canvas pan, zoom, and rotation.

Site Viewer is a 3-D map display and requires hardware graphics support for WebGL™.

Opening Site Viewer using siteviewer allows customization of basemap, terrain, and buildings.

Dimension Picker

The dimension picker offers three choices: 3-D, 2-D, and Columbus View.

  • 3-D View – Provides a smooth globe. This is the default view.

  • 2-D View – Provides a flat map in Mercator projection.

  • Columbus View – Provides a flat map in Mercator projection that allows tilt and rotation.

Basemaps

Basemaps are the underlying maps used by Site Viewer.

You can select the basemaps using the basemap picker. You need an active internet connection for all basemaps except Dark Water. The following options are available:

  • Satellites

  • Streets

  • OpenStreetMap

  • Dark Water

  • Gray Land

  • Blue Green

  • Gray Terrain

  • Color Terrain

  • Land Cover

By default, Site Viewer uses Satellites. You need an active internet connection for all basemaps except Dark Water.

Use Satellites for high-quality satellite imagery. Use Streets, or OpenStreetMap for imagery of roads, labels, and political boundaries.

Use The MathWorks® natural earth basemaps for low resolution but more controls and color scheme options in basemaps.

Basemaps

Two-Tone BasemapsDescriptionNatural Earth BasemapsDescription

'darkwater'

Land areas: light-to-moderate gray

Ocean and water areas: darker gray

This is the default map.

'colorterrain'

Shaded relief combined with custom elevation colors based on climate—humid lowlands are green and arid lowlands brown.

'grayland'

Land areas: light-to-moderate gray land

Ocean and water areas: white

'grayterrain'

Worldwide terrain depicted monochromatically in shades of gray, combining shaded relief that emphasizes both high mountains and the micro terrain found in lowlands.

'bluegreen'

Land areas: light green

Ocean and water areas: light blue

'landcover'

Satellite-derived land cover data and shaded relief presented with a light, natural palette suitable for making thematic and reference maps (includes ocean-bottom relief).

View Latitude and Longitude Coordinates of Location

Use Site Viewer to view the latitude and longitude coordinates of any location. To view the latitude and longitude, right-click the map and select Show Location.

To remove the location, right-click the location and select Remove Location.

Limitations for Terrain and Buildings

Terrain

  • Default terrain access requires internet connection. If no internet connection exists, then Site Viewer automatically uses 'none' in the property Terrain.

  • Custom DTED terrain files for use with addCustomTerrain must be acquired outside of MATLAB® for example by using USGS EarthExplorer.

  • When using custom terrain, analysis is restricted to the terrain region. For example, an error occurs if trying to show a txsite or rxsite outside of the region.

Buildings

  • OpenStreetMap files obtained from https://www.openstreetmap.org represent crowd-sourced map data, and the completeness and accuracy of the buildings data may vary depending on the map location.

  • When downloading data from https://www.openstreetmap.org, select an export area larger than the desired area to ensure that all expected building features are fully captured. Building features at the edge of the selected export area may be missing.

  • Building geometry and features are interpreted from the file according to the recommendations of OpenStreetMap for 3-D buildings.
