Files that contain the .cmap file extension are most commonly used by the C-map MAX Cartography Catalog software. The C-map Max Cartography Catalog program is used to create nautical map charts. The charts that are created with this software are then stored with the .cmap file extension.
The .cmap file suffix is also used by the IHMC CmapTools software application. This program is used to create mind-map diagrams for use during the brainstorming process. The brainstorming diagrams that are created with the software are saved with the .cmap file suffix.
The .cmap file suffix is also used for colormap files. This file format is based on the OFF file format. The CMAP files normally have a corresponding OFF file associated with them.
