Finding the data you need for your project is one thing, but keeping track of it inside a project with dozens of maps and hundreds of layers can be difficult. You can filter what you don\u2019t need to see from the Contents<\/strong> pane, but maps are a visual experience\u2014sometimes you just don\u2019t want to see a layer right now. And you don\u2019t want to keep having to make manual adjustments. What\u2019s not currently drawing in the view still takes space in the pane and uses your system’s resources.<\/p>\n To solve that dilemma, ArcGIS Pro 3.1 introduces a new layer type\u2014something we don\u2019t get to say very often. Catalog layers may be useful for those who work with ArcGIS Pro maps or scenes that contain a large amount of data. Today we will share an example of how catalog layers<\/a> can be used.<\/p>\n It\u2019s called a catalog layer because its purpose is to help you organize, or catalog, your datasets. A catalog dataset is created and stored in a geodatabase and establishes item references with the data it includes. The item references point to various data sources\u2014from local or network file shares, or your Enterprise portal.<\/p>\n With catalog layers, data management tasks are minimal. You\u2019re not breaking existing data connections or duplicating anything. Think of it this way: the catalog dataset is a file cabinet. Each item reference to a dataset, feature class, or service is a file in the cabinet. You\u2019ll frequently pull out the files you want to see, and the ones you don\u2019t need right now are put in the back of the cabinet\u2014but they are still<\/em> in the cabinet. I\u2019ll come back to this analogy throughout the blog because it can simplify what is going on behind the scenes.<\/p>\n There are core aspects to creating catalog layers, such as item type filters, that I don\u2019t cover in this blog post. If you\u2019re curious about how you can create a catalog dataset and establish item references, you can read the web help documentation<\/a> and follow the instructions provided.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":1890112,"id":1890112,"title":"ex1_FileCabinet","filename":"ex1_FileCabinet.png","filesize":1140948,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/03\/ex1_FileCabinet.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/mapping\/build-analyze-and-filter-catalog-layers-in-arcgis-pro\/ex1_filecabinet","alt":"Hurricane Harvey and Hurricane Irma geographic data","author":"9702","description":"","caption":"","name":"ex1_filecabinet","status":"inherit","uploaded_to":1873902,"date":"2023-03-29 18:04:04","modified":"2023-03-29 18:43:19","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":1487,"height":794,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/03\/ex1_FileCabinet-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/03\/ex1_FileCabinet.png","medium-width":464,"medium-height":248,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/03\/ex1_FileCabinet.png","medium_large-width":768,"medium_large-height":410,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/03\/ex1_FileCabinet.png","large-width":1487,"large-height":794,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/03\/ex1_FileCabinet.png","1536x1536-width":1487,"1536x1536-height":794,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/03\/ex1_FileCabinet.png","2048x2048-width":1487,"2048x2048-height":794,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/03\/ex1_FileCabinet-826x441.png","card_image-width":826,"card_image-height":441,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/03\/ex1_FileCabinet.png","wide_image-width":1487,"wide_image-height":794}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":" Now, imagine you work for a natural disaster agency that collects data for an incoming Category 3 storm.
