Geophysical gravity survey is a method to acquire subsurface information of a target area. Usually this method is a preliminary survey to distinguish the prospect of an area. G r a vity survey measures the gravity variation of an area to obtain the density <br /> <br /> variation or to locate density anomaly. With this information we can acquire and study what is under the survey area. <br /> <br /> G ravity data acquisition involves variables such as coordinates (x, y, z) and relative gravity value of each measurement locations. To attain gravity anomaly data which is ready to be process, further correction procedures are required. If done manually it consumes a lot of time and there is a possibility of mistakes. While existing software are quite expensive. <br /> <br /> T h erefore the programming and use of my software to calculate gravity reduction value will accelerate and ease the processing of gravity acquisition data. This software calculates from diurnal correction to residual regional anomaly separation using trend surface analysis (TSA).
