A predominance map helps us see new geographical patterns by comparing multiple attributes from our data. By showing us the largest value between many attributes, we gain new insights\u00a0about how data might be grouped geographically.<\/p>\n

For example, an election map is an example of a predominance map where each area is red or blue based on if there are more Republicans or Democrats voting for something.

You asked, and we listened!<\/h2>\n

With the April 2018 release of ArcGIS Online, you can now compare up to ten attributes<\/strong> within your dataset using the predominance mapping style<\/a>. This broadens the possibilities of maps that you can create with your data.<\/p>\n

There are also new color ramps<\/strong> available specifically for predominance. For example, there is a new sequential color ramp designed to show a progression. In the map below, this color ramp is used to highlight the level of education for the population, where yellow is the lowest level of education and red is the highest level of education.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":146381,"id":146381,"title":"BlogScreenshot","filename":"BlogScreenshot.png","filesize":257394,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/BlogScreenshot.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-online\/mapping\/whats-new-in-predominance-mapping-april-2018\/blogscreenshot","alt":"","author":"6461","description":"","caption":"","name":"blogscreenshot","status":"inherit","uploaded_to":142591,"date":"2018-04-11 23:30:11","modified":"2018-04-11 23:30:11","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":1488,"height":966,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/BlogScreenshot.png","thumbnail-width":213,"thumbnail-height":138,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/BlogScreenshot.png","medium-width":402,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/BlogScreenshot.png","medium_large-width":768,"medium_large-height":499,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/BlogScreenshot.png","large-width":1488,"large-height":966,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/BlogScreenshot.png","1536x1536-width":1488,"1536x1536-height":966,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/BlogScreenshot.png","2048x2048-width":1488,"2048x2048-height":966,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/BlogScreenshot.png","card_image-width":716,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/BlogScreenshot.png","wide_image-width":1488,"wide_image-height":966}},"image_position":"center","orientation":"horizontal","hyperlink":"https:\/\/www.arcgis.com\/home\/webmap\/viewer.html?webmap=17e9e85b565f472c83eb8041eb0a035a"},{"acf_fc_layout":"image","image":{"ID":142641,"id":142641,"title":"PredominanceRamps","filename":"PredominanceRamps.png","filesize":3084,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/PredominanceRamps.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-online\/mapping\/whats-new-in-predominance-mapping-april-2018\/predominanceramps","alt":"","author":"6461","description":"","caption":"","name":"predominanceramps","status":"inherit","uploaded_to":142591,"date":"2018-04-10 23:27:56","modified":"2018-04-10 23:27:56","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":380,"height":409,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/PredominanceRamps.png","thumbnail-width":186,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/PredominanceRamps.png","medium-width":242,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/PredominanceRamps.png","medium_large-width":380,"medium_large-height":409,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/PredominanceRamps.png","large-width":380,"large-height":409,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/PredominanceRamps.png","1536x1536-width":380,"1536x1536-height":409,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/PredominanceRamps.png","2048x2048-width":380,"2048x2048-height":409,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/PredominanceRamps.png","card_image-width":380,"card_image-height":409,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/04\/PredominanceRamps.png","wide_image-width":380,"wide_image-height":409}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

These new enhancements will allow you to create new types of predominance maps, and broaden your cartographic options.<\/p>\n

To make a predominance map, simply select the attributes you want to compare within the \u201cChange Style\u201d option, and smart mapping will automatically draw the largest attribute within the map. Check out this Story Map<\/a> for an introduction and tutorial for getting started with predominance. You can also check out this short video<\/a> to see how it\u2019s done.<\/p>\n
