The property is a rectangle with a small square added on the lower right hand side. Deepmapper handles the plotting just fine and the example you gave does not have any missing parts or errors. As for the Streets it is a reference for a starting point, in this case it is telling you to go down center st 407.58 ft from where it intersects Farnum st. That is where the first corner of the plot begins. In deedmapper you can add the names of the owners property on the plot which will help you as you add in the neighbors lands. I recommend you do a little reading on the deedmapper web site on platting land as it will give you a better understanding of the process and what the deed is really saying. Charlotte
