The GMD extension is used in the Game Maker video game developing program to store saved program files. Saved projects are stored with the GMD extension. GMD files can be edited with the appropriate software.
The file extension .gmd is implemented by the Great Budget application, as the Model Definition applied to its Templates. The application that produces the file extension .gmd is classified as a Project Centric Control and Planning System, which can also be integrated into existing primary systems and data. The program uses the .gmd file extension in assessing the final cost of a project and potential risks and impacts, should a proponent decide to decrease the allocated budget. It also helps to verify proper resource utilization in terms of identified project objectives, to help enterprises maximize not only budget allocation, but resource management as well.The main focus of the .gmd file extension is to provide a foundation for existing enterprise procedures, by producing more intensive and accurate budgeting methodologies. CRISMS (Cost/ Risk Identification and Management System), technology associated with the file extension .gmd, has been the basis for various scenario simulations in the identification of cost effective project reviews.ERDAS IMAGINE, which is a utility, implemented in the creation and execution of Geographic Expert Systems and used in post and image classification and refinement for advanced modeling of GIS, associates the file extension .gmd with its Graphical Model. The .gmd file extension provides a valuable data source for capturing actual events based on specific location and times around the world, which is used as reference materials in understanding Earth changes that take place over a period of time.http://www.erdas.com/
