+xYou are using the term MORA, I am unsure where you got that from. SkyDemon can show maximum grid elevations, which is the highest hard stuff (terrain or obstacle attached to terrain) that we know of in that grid square. It's then up to the pilot to add whatever safety margin they wish to that figure, if they want to do something with it.
, or depending from chart publisher, sometime
AMA Area Minimum Altitude, have the same use.
There are two types of Minimum Off Route Altitudes (MORAs) – one is called a route MORA and the other is the grid MORA.
MORA's give at least 1,000 feet altitude clearance above terrain, and 2,000 feet in mountainous (an area of changing terrain were the changes of terrain elevation exceed 3000 feet within a distance of 10NM) terrain.
Route MORAs provided an obstacle clearance within 10 nautical miles (19 km) on both sides of the airways and within a 10-nautical-mile (19 km) radius around the ends of the airways.
Grid MORAs provide an obstacle clearance altitude within a latitude and longitude grid block, usually of one degree by one degree. They are presented in feet (ft), omitting the last two figures. Example: 7,600 feet is given as 76.
Grid MORA values clear all terrain and obstructions by 1000 feet in areas where the highest elevations are 5000 feet MSL or lower. MORA values clear all terrain by 2000 feet in areas where the highest elevations are 5001 feet MSL or higher.
Route MORA are typical IFR use or on Airway, Grid MORA are used in VFR on area G.
Better indicate clearly, on SkyDemon User Manual, that your AMA or MORA (name is not important) do not consider buffer and indicate the maximum obstacle altitude on the grid.
The majority of Pilots learned that Grid MORA (AMA) indicated on charts, are calculated with the buffer as per above.
All ICAO standard charts follow the rule.
Hoping to be helpful to the improvement of SD,
my best regards,
