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.
The technical name for this condition is âchronic venous insufficiencyâ (CVI) but not all swollen legs are caused by CVI. Get your legs checked by a doctor just in case you have a heart or kidney problem, which can also cause water retention in legs feet and ankles. Swollen legs are also common in pregnancy and are caused by the pressure of the baby on the veins in the pelvis.
