ArcMap is run using primarily Shape Files and in more recent versions Geodatabases can be used to store larger sets of data. These file formats are what are uploaded into the program to view spatial data.
Edema is swelling of both legs from a buildup of extra fluid. Prolonged standing or sitting, especially in hot weather, can cause excess fluid to accumulate in the feet, ankles and lower legs. Tiny valves inside the veins of the legs can become weakened, causing a common problem called venous insufficiency.
Swelling in the legs is often caused by edema, which can be treated with at-home remedies. About 4.4 million people in the U.S. suffer from edema. Also called âwater retention,â edema is a condition where fluid accumulates beneath the skin somewhere in the body, creating a puffy appearance.
