It's time for the next step in our How it's Done Series! This month, we focus on our Scan Processing step. In this step, we take a newly scanned document, and we crop it, position it to the north, add our title block and make sure it is ready for public view! #howitsdone #minemap

Post #3 is Inventory! Every map that enters NMMR is first inventoried. Our team checks if it’s a duplicate or new addition. If it’s new, we assign a unique NMMR ID in our database & place the number on the back of the map to keep our collection organized & preserved. #howitsdone
