ArcGIS Arcade<\/a> is an expression-based scripting language for data in your maps. You can use it to do basic calculations, convert field types, and configure symbols, labels, transparency, and pop-ups\u2014all without leaving the map. And you don\u2019t have to be a developer or GIS expert. Arcade is for anyone who wants to transform their data values on-the-fly.<\/p>\n

A common use case for Arcade is changing the total number to a percentage.<\/p>\n

For example, imagine you\u2019re supporting an evacuation effort in Houston, Texas for an incoming hurricane. You need to pinpoint areas that may have difficulty evacuating in time.\u00a0 You have data in a map that shows the total number of households without a vehicle in each census tract. It would be more meaningful to identify the tracts with a high percentage of households without a vehicle based on the total population.<\/p>\n

By writing a basic Arcade expression, you can easily change the total number to the percentage of households with a vehicle. And don\u2019t be intimated by the idea of creating expressions! Arcade guides you along the way.<\/p>\n"},{"acf_fc_layout":"storymap","title":"","description":"","static":false,"storymap_url":"https:\/\/www.arcgis.com\/apps\/Minimalist\/index.html?appid=a1e32b7eb6d14154928b164df0b32e11<\/a>"},{"acf_fc_layout":"content","content":"
