![]() Once the webmap is open and the source feature layer and feature layer view have been added to the map, you can begin modifying symbology for one or both layers. In many cases, it may be more desirable to create a new webmap strictly for displaying information and tracking the collection of data. This can be different than the map in which data collection is being performed, or the same one. Open an existing webmap, or create a new webmap to display the data in. You will notice to the right there are several options, select Create View.Īssign a unique title, description, tags, and a location to save the view and click OK. To begin creating and utilizing feature layer views, open up the feature layer which you would like to create a view for in the My Content section of ArcGIS Online by clicking on the layer name. ![]() As previously mentioned, this functionality is called “Feature Layer Views”, and a basic diagram of its usefulness can be seen below. This is a great way to reduce duplication of efforts when creating maps, while at the same time visualizing information from more than one attribute.Īround the beginning of the new year, ESRI released new functionality to ArcGIS Online which facilitates this. Each instance of the spatial file can have its own unique symbolization settings and templates applied to it. In a desktop GIS application, a single spatial file can be represented in a dataframe one or more times. Called “Feature Layer Views”, this new type of data storage allows a commonly utilized symbolization method in desktop GIS to be applied to ArcGIS Online feature layers. ![]() The book is available through and other booksellers, and is also available at for free.ESRI recently implemented new functionality into ArcGIS Online which greatly expands the ability of the webmaps that are created and hosted there. The twin goals of this book are to open your eyes to what is now possible with Web GIS, and then spur you into action by putting the technology and deep data resources in your hands. This post is excerpted from The ArcGIS Book: 10 Big Ideas about Applying Geography to Your World. Once you create your map, you can configure an app that will use your web map for delivery to your audience. Share your map by using it to configure a whole range of apps. Every map, especially a map that you will share, needs a good item description, thumbnail, and name.ĥ. Save your map, then document it with an eye-catching thumbnail, a good description, and a thoughtful name. Create pop-ups that enable users to explore the clicked-on features.Ĥ. Simply share the hyperlink, embed it in a website, or share the configured app.ģ. In this case, we’ll add point layers for specific San Diego destinations, line layers for the trolley lines, and neighborhood polygons. Add your data layers and specify how each will be symbolized and displayed. We’ll use the Light Gray Canvas basemap.Ģ. Select a basemap and zoom into your city of interest. Suppose you want to make a map that allows you to explore the food, architecture, and design destinations for San Diego.ġ. Let’s start by going through a short example. Make and Share a Web Map in Five Easy StepsĪnyone can make, share, and use web maps. You simply provide a hyperlink to the web map you wish to share and embed it on websites or launch it using a wide range of GIS apps. Web maps are how you deploy your Web GIS. ![]() This web map asks a simple question: how many Americans live within a reasonable walking or driving distance to a supermarket or other sources of healthy food? Web maps are how users work with and apply ArcGIS, and can be used anywhere-in web browsers, on smartphones, and in desktop GIS applications. Web maps work online and on any smartphone, and along with your supporting GIS work, are accessible anytime. Virtually anything you do with GIS can be shared using web maps. Then add additional tools that support what you want your users to do with your web map: tell stories perform analytical studies collect data in the field or monitor and manage your operations. Start with a basemap and mash it up with your own data layers. The tools can do simple things like open a pop-up window when you click on the map, or more complex things, like perform a spatial analysis and tell you the relative proximity of healthy food options by neighborhood.Īt their heart, web maps are simple. Each web map contains a reference basemap along with a set of additional data layers, plus tools that work on these layers. They are shared on the web and across smartphones and tablets. Web maps are online maps created with ArcGIS that provide a way to work and interact with geographic content organized as layers.
