Learn to use filters and the drop shadow effect to best highlight your data.","pdf":{"host_remotely":false,"file":"","file_url":""},"flexible_content":[{"acf_fc_layout":"content","content":"With massive amounts of data at your fingertips, it can be hard to bring focus to the maps you make daily. Resources like ArcGIS Living Atlas of the World bring a wealth of national and local datasets directly into your map with just a few clicks. But often, maps can easily become overwhelmed by data.\r\n\r\nInstead of throwing data at your intended audience, make a policy map that emphasizes the most important patterns in your data and clearly shows opportunities to intervene based on those patterns. You can make small changes to your maps that shift the focus to the most important parts of the narrative. In this tip, learn to highlight specific features within your thematic maps in the ArcGIS Online map viewer by narrowing your focus with filtering and drop shadow effects.\r\n\r\nHighlight Your Area of Interest<\/strong>\r\n\r\nThe most fundamental way to focus a map on your area of interest is to filter out data that isn\u2019t as important. Effects like drop shadow can enhance this technique to make specific features on the map stand out in order to create or shape a policy narrative.\r\n\r\nSign in to your ArcGIS Online account to follow along using\u00a0this web map<\/a>. It shows poverty percentages by census tract using American Community Survey (ACS) census data in the ArcGIS Living Atlas layer\u00a0ACS Poverty Status Variables \u2013 Boundaries<\/a>. The example in this tip will focus on the Houston, Texas area.\r\n\r\nBy opening the Layers pane on the left side of the map viewer, you\u2019ll notice that the example map includes both an original data layer and several grouped layers that are hidden by default. The hidden layers demonstrate multiple ways of highlighting specific features to achieve different effects. This tip will teach you to achieve some of the same results by manipulating settings on the original data layer. You can then replicate the results with other Living Atlas layers or your own data, turning your maps into effective policy maps."},{"acf_fc_layout":"image","image":539122,"image_position":"left","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"Step 1: <\/strong>With the Original Data Layer selected, open the Filter pane on the right side of the map viewer.

In this case, it is filtered to Harris County.\r\n\r\nSee this blog<\/a> for more about filtering without built-in fields and other information about emphasizing your area of interest.\r\n\r\nStep 2: <\/strong>Open the Effects pane on the right side of the map viewer.\r\n\r\nStep 3:<\/strong> Click Drop shadow.

To accomplish this, first make some small adjustments to the settings you just configured.\r\n\r\nStep 4: <\/strong>On the Filter pane, click the trash can icon next to Remove Filter.
