Excel file for Computing Property (land) Area, and Drawing the Map

Several years ago, I started to track down all the properties of my mother in the province... All I needed are the coordinates, which usually can be found either in the TCT or in Lot Data from the Bureau of Lands... Being on the 'road' I do not have the time nor the equipment to draw the property limits, so I had to make an excel file capable of such... using Mathematics , I was able to make a program... below is an example of an unknown lot, but with coordinates, I was able to draw its shape and compute for the land area... All I have to do now is look for it within the area... and in this case, it was pretty easy to find it!
