Referenced layer types include the following:<\/p>\n<ul>\n<li>Map service<\/li>\n<li>Feature service<\/li>\n<li>Image service<\/li>\n<li>KML<\/li>\n<li>OGC WMS<\/li>\n<li>CSV<\/li>\n<\/ul>\n<p>You can also import local data from files on your computer, and create editable layers (e.g. map notes) that let you add data interactively to your map. These layer types are stored within your map, and include the following:<\/p>\n<ul>\n<li>Delimited text file (.csv and .txt)<\/li>\n<li>Shapefile (.zip)<\/li>\n<li>GPS file (.gpx)<\/li>\n<li>Editable layers created in the\u00a0ArcGIS.com\u00a0map viewer (map notes)<\/li>\n<\/ul>\n<p>While there are common properties, each layer type also has unique properties and capabilities, including the order in which they appear in the map contents.<\/p>\n<p>See\u00a0<a title=\"View help topic\" href=\"http:\/\/resources.arcgis.com\/en\/help\/main\/10.1\/01w1\/01w10000006v000000.htm\" target=\"_blank\" rel=\"noopener\">About working with layers<\/a>\u00a0for more details.<\/p>\n<p><strong>Drawing order<\/strong><\/p>\n<p>Layers above others in Contents draw on top of layers lower down in the list.\u00a0 This is important when you are designing your map so that you provide your audience with the best possible experience.\u00a0 You\u2019ll want to minimize the chance that important symbols or labels are obscured by less important aspects of your map.<\/p>\n<p>Though there isn\u2019t a visual indication, the web map\u2019s layers are are separated into several sections in Contents based on the layer type.\u00a0 While you can reorder layers within each section, it\u2019s not possible to move layers between sections or change the order of the sections themselves.

sources) are drawn by the browser you can adjust their symbols in the web map.\u00a0 Other capabilities for feature layers include setting the transparency and visibility range and changing the layer name.<\/p>\n<p>Because feature layers are managed by the browser, it\u2019s important to be conscious of the number and complexity of features being drawn.\u00a0 You may want to set a visibility range so that these layers only draw at scales where a reasonable number of features are being drawn at once (also reducing map clutter).\u00a0 You can improve performance of feature layers by using scale dependencies, and \u00a0also by simplifying the geometries for line and polygon layers when you import them or before you publish them.<\/p>\n<p>Note that the management of features is dependent on the browser, and different browsers will yield different performance results.<\/p>\n<p>For more information see:<\/p>\n<ul>\n<li><a title=\"View help topic\"

information.<\/p>\n<p><strong>Adding individual layers from a map service<\/strong><\/p>\n<p>If you have a map service with several layers, you can add a single layer from the service to your web map. This works by adding the sublayer directly from the service as a feature layer rather than adding the entire map service (meaning feature geometries are sent to the client and the browser draws them on the map).<\/p>\n<p>Since the server is no longer drawing tiles you have some different visualization options for map service sublayers such as being able to modify the symbols in the web map.\u00a0 Also, the layer will appear in the section with feature services and file-base sources, so it will be on top of all your other map\/image services.<\/p>\n<p>It\u2019s important, however, to note that any labels defined on the sublayer will not be visible when it is added as a feature layer.\u00a0 Also, you may experience a performance drop since the browser is now drawing the features instead of a server.\u00a0 As stated above, consider the use of a visibility range to counteract this effect.<\/p>\n<p><strong>The Basemap<\/strong><\/p>\n<p>The bottom layer in your web map is always the basemap.\u00a0 The basemap must be an ArcGIS for Server map or image service or a hosted tile service from ArcGIS Online. It\u2019s recommended that you use a cached map service or hosted tile service for the basemap.\u00a0You can rename the basemap layer, hide it in the legend, and adjust its transparency (useful to\u00a0<a title=\"View blog post\" href=\"http:\/\/blogs.esri.com\/esri\/arcgis\/2011\/08\/11\/using-basemap-transparency\/\" target=\"_blank\" rel=\"noopener\">make other layers stand out<\/a>).<\/p>\n<p>While there can be only one basemap layer in a web map, some ArcGIS Online basemaps include multiple reference services.\u00a0 These additional services usually contain labels and\/or boundaries that are drawn on top of your other map layers.\u00a0 The reference layer will not appear in the Contents list but will be drawn at the top of the map and image service layers section.<\/p>\n<p>An example of an ArcGIS Online basemap with a reference service is the\u00a0<a href=\"http:\/\/www.arcgis.com\/home\/item.html?id=8b3b470883a744aeb60e5fff0a319ce7\">Light Gray Canvas basemap<\/a>, which is composed of the\u00a0<a href=\"http:\/\/www.arcgis.com\/home\/item.html?id=ed712cb1db3e4bae9e85329040fb9a49\">World Light Gray Base<\/a>\u00a0and\u00a0<a href=\"http:\/\/www.arcgis.com\/home\/item.html?id=87fcdf91a0f14e4a9fda40a763c6f2b8\">World Light Gray Reference<\/a>\u00a0layers.<\/p>\n<p>Besides choosing your own basemap, you can add your own basemap from ArcGIS services and WMS layers.
