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.
âCanklesâ are calves joining knees with ankles without any change in leg size. Swollen legs neither look pretty nor are a sign of good health. Yet despite cosmetic and health implication swollen legs are rarely properly taken care of. The causes of swollen legs usually lie in lymphatic and venous stasis, which, in turn, are due to chronic imbalance between body water and minerals.
