Ancient Sumerians used a base-60 system for dividing up a whole into parts, probably because it’s divisible by a lot of small numbers making it a handy and quick shared reference. A couple thousand years or so later, the tremendous polymath Eratosthenes<\/a> (who, among other things, invented the discipline of geography) used this system to divide up the Earth itself into pieces. This was refined and normalized by Hipparchus a bit later. Ptolemy then expanded these divisions into 360 even slices, but he divided each slice into two levels of the handy Sumerian 60 smaller parts<\/em>, to support the precision needed by explorers, engineers, and cartographers. These smaller parts were named partes minutae primae<\/em> (primary smaller parts) and each one of these was further divided into 60 partes minutae secundae<\/em> (secondary smaller parts). But it’s easier just to say minutes and seconds.<\/p>\n

Not coincidentally, clock faces are round and are divided up into even pieces. But it wasn’t until a few hundred years ago that advancements in timekeeping engineering brought about the capacity for more precision and a practical standard was needed for slicing up our newly fastidious concept of time up into smaller parts<\/em>. Minutes and seconds were right there ready to swoop in and answer the call. Geography to the rescue.<\/p>\n

I know it’s a rather bold proposal to ask you to invest a fraction of your allotted time on this earth with me, as I show you some map hack you may or may not already know how to do. But it doesn’t sound as bold when I describe it as one minute<\/em> fraction of your day, right?<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":628282,"id":628282,"title":"OMMH_Logo","filename":"OMMH_Logo.png","filesize":37220,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/10\/OMMH_Logo.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/mapping\/one-minute-map-hacks-1-5\/ommh_logo","alt":"","author":"6971","description":"","caption":"","name":"ommh_logo","status":"inherit","uploaded_to":628272,"date":"2019-10-07 13:59:13","modified":"2019-10-07 13:59:13","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":201,"height":108,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/10\/OMMH_Logo.png","thumbnail-width":201,"thumbnail-height":108,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/10\/OMMH_Logo.png","medium-width":201,"medium-height":108,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/10\/OMMH_Logo.png","medium_large-width":201,"medium_large-height":108,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/10\/OMMH_Logo.png","large-width":201,"large-height":108,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/10\/OMMH_Logo.png","1536x1536-width":201,"1536x1536-height":108,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/10\/OMMH_Logo.png","2048x2048-width":201,"2048x2048-height":108,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/10\/OMMH_Logo.png","card_image-width":201,"card_image-height":108,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/10\/OMMH_Logo.png","wide_image-width":201,"wide_image-height":108}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"
