WinProm is a Windows tool for calculating the topographic prominence of mountains. It was written by Edward Earl, a pioneer in prominence research and calculation.

Building the code

WinProm compiles with Microsoft Visual Studio 2015 Community Edition. You can download it for free from Microsoft's Web site. Be sure to install the Visual C++ compiler and the MFC libraries; these are not installed by default.

Each program has Debug, Release, and Distribute targets. The Distribute target has some important functionality disabled, therefore, it's recommended that you generally use the Release target.

Release binaries of WinProm and winelev are checked in at the top level.

File formats

WinProm takes as input .elv raster files. The winelev program, also included here, can convert from several common file formats to .elv.

Here is an example of how to find prominences with WinProm:

  • Download some terrain data from

  • Run winelev and convert the terrain data to a .elv file

  • Run WinProm, open the .elv file via File | Open | Elevation Map, then find prominences via Operation | Analyze | Peaks.
