boundImageSize

Read the capabilities document from the EOX::Maps server. For more information about EOX::Maps, see EOX::Maps. Extract the list of layers from the capabilities document.

info = wmsinfo("https://tiles.maps.eox.at/wms?");
eox = info.Layer;

Get a layer containing terrain data. Then, create a WMS map request from the layer. Update the map request to set all pixels that do not represent features or data values to a transparent value.

layer = refine(eox,"terrain-light",MatchType="exact");
request = WMSMapRequest(layer);
request.Transparent = true;

Set the bounds of the map request to 720 pixels. Then, use the map request to read an image from the server.

request = boundImageSize(request,720);
globalImage = getMap(request.Server,request.RequestURL);

Note that the width of the image is 720 pixels.

size(globalImage)

ans = 1×3

   360   720     3

Display the image on a map. The rendered map has a spatial resolution of 0.5 degrees per cell and an image size of 360-by-720 pixels.

Read the capabilities document from the EOX::Maps server. For more information about EOX::Maps, see EOX::Maps. Extract the list of layers from the capabilities document.

info = wmsinfo("https://tiles.maps.eox.at/wms?");
eox = info.Layer;

Create an array of multiple layers that includes terrain, coastlines, and hydrography.

terrain = refine(eox,"terrain-light",MatchType="exact");
coast = refine(eox,"coastline_black",MatchType="exact");
hydro = refine(eox,"hydrography",MatchType="exact");

layers = [coast; hydro; terrain];

Create a WMS map request from the layer. Update the map request to set all pixels that do not represent features or data values to a transparent value.

request = WMSMapRequest(layers);
request.Transparent = true;

Set the latitude and longitude limits of the request to a region surrounding Dublin, Ireland.

dublin = geocode("Dublin, Ireland","city");

extent = [-0.25 0.25];
request.Latlim = dublin.Shape.Latitude + extent;
request.Lonlim = dublin.Shape.Longitude + extent;

Set the bounds of the map request to 1024 pixels. Then, use the map request to read an image from the server.

request = boundImageSize(request,1024);
dublin = getMap(request.Server,request.RequestURL);

Note that the height and width of the image are 1024 pixels.

size(dublin)

ans = 1×3

        1024        1024           3

Display the image on a map. The rendered map has a spatial extent of 0.5 degrees and an image size of 1024-by-1024 pixels.
