Add custom terrain data


addCustomTerrain(terrainName,files) adds terrain data specified by files for use with UAV scenarios. Add the terrain to uavScenario objects using the addMesh object function. Custom terrain data is available for current and future sessions of MATLAB® until you call removeCustomTerrain.

addCustomTerrain(___,Name,Value) adds custom terrain data with additional options specified by one or more name-value pairs.

Input Arguments

collapse all

User-defined identifier for terrain data, specified as a string scalar or a character vector.

Data Types: char | string

List of DTED files, specified as a string scalar, a character vector or a cell array of character vectors.


If you specify multiple files, they must combine to define a complete rectangular geographic region. If not, you must set the name-value pair 'FillMissing' to 'true'.

Data Types: char | string

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: 'FillMissing',true

Attribution of custom terrain data, specified as a character vector or a string scalar. Attributions display on geographic plots that use the custom terrain. By default, the attribution is empty.

Attribution of custom terrain data, specified as a character vector or a string scalar. The attribution data is not displayed in UAV scenarios, but can be displayed on geographic plots or the Site Viewer map. By default, the value is empty.

Data Types: char | string

Fill data of missing files with value 0, specified as true or false. Missing file values are required to complete a rectangular geographic region with the input files.

Data Types: logical

Name of folder to write extracted terrain files to, specified as a character vector or a string scalar. The folder must exist and have write permissions. By default, addCustomTerrain writes extracted terrain files to a temporary folder that it generates using the tempname function.

Data Types: char | string


  • You can find and download DTED files by using EarthExplorer, a data portal provided by the US Geological Survey (USGS). From the list of data sets, search for DTED files by selecting Digital Elevation, SRTM, and then SRTM 1 Arc-Second Global and SRTM Void Filled.
