By Jim Herries and Tamara Yoder, ArcGIS Content Team Every item in ArcGIS Online has a thumbnail image to give a visual cue as to what the item is or contains. Have you noticed that items in the Living Atlas, StoryMaps website, and the Esri Marketplace have large thumbnails? With the latest update to the Living Atlas Contributor App, you can now upload both a small and large thumbnail for each item you wish to nominate. Every item in ArcGIS Online can have a small thumbnail that is 200 x 133 pixels in size, and a large thumbnail that is 286 x 190 pixels in size. These thumbnails help people remember your layer, web map, scene, map package, story map, so it’s important that they look good, and that they communicate what the item is or contains. So what makes a good thumbnail? Well, it depends on the type of item you want to share. A thumbnail for a web map will most likely differ from that of a web scene, because you want the web scene’s thumbnail to communicate that this item contains a 3D scene of the subject. Let’s start with the most common item type: layers and web maps. Many layer items and web map items in ArcGIS Online have a thumbnail that emphasizes the extent of the data rather than what that data looks like at a useful scale. If your layer contains locations of code violations around the city, make a thumbnail that shows that at the neighborhood scale. The layer title might be “Peoria Code Violations” – let the title communicate that the layer’s extent includes all of Peoria, and let the thumbnail show what the data looks like at its best scale. Of course, there are good reasons to show the whole geographic context in the thumbnail. Do what works best for your audience. A web map has many layers, so its thumbnail might include an area that shows those layers working together to deliver the desired information, whereas the thumbnail for a single layer might emphasize what that layer looks like at its best scale. Applications benefit from thumbnails that depict what the application looks like (in miniature form of course), or depict a particular piece of information the app is good at delivering (e.g. a dashboard element, a chart, a graph, a popup, etc.). Story maps are often given thumbnails that look like the first page of the story map. Many people incorporate corporate logos and icons into the thumbnails. Why is that? Once you start creating items, eventually you realize that what you have is a family of related layers, maps, scenes, apps, story maps, etc. You may want to include a little indicator on each thumbnail so that it’s obvious who stands behind it, or how it can be used. If you’ve never created your own thumbnail, you’ll find the instructions below useful. It’s easy to create thumbnails. Step 1: Get something onscreen that looks the way you want it to look. Step 2: Take a screenshot. Step 3: Crop, or resize, to fit the desired large or small size. Step 4: Upload your custom thumbnail and press Save. Please find below basic steps for capturing thumbnails on either a PC or a Mac. PC Open the item page in ArcGIS Online. Click on the item to open it in its default viewer (layers and web maps open in ArcGIS Online viewer, web scenes open in Scene Viewer, web apps open in a browser, etc.). Zoom and pan until you find a view that displays the item and its content at its best. When ready to take a screenshot, press the Windows logo key-PrtScn for a screen shot of your entire screen. This key might appear as PrtSc or another similar abbreviation. Some devices may not have a PrtScn key or could use a different key combination to capture the screen. It is recommended you check the manual or complete a quick internet search to find specific screen capture shortcuts for your device. Screenshots are saved as .png files in the Pictures > Screenshots folder in Windows v8.1/8.1 RT and later. They’re automatically named “Screenshot (number).png.” Go find your screenshot, right-click on it and choose to Open with > Paint to edit it. If you have Windows 7 please reference this Microsoft article and Windows Vista take a look at this article. Crop the map image to focus on an interesting area that is 286×190 or 200×133 pixels. Save the image. For thumbnails of apps and story maps, maximize your browser, get the app to look the way you want, maybe click on the map to show a popup or chart, and press the Windows logo key-PrtScn to capture the entire screen. Go find your screenshot, right-click on it and choose to Open with > Paint to edit it. Crop the image to cut out any extra stuff outside the browser window, and resize that image to 286×190 or 200×133 pixels. This can be completed by using the Resize button located on the Home tab. Save the image. Go back to your item page and upload the image. Mac Open the item page in ArcGIS Online. Click on the item to open it in its default viewer (layers and web maps open in ArcGIS Online viewer, web scenes open in Scene Viewer, web apps open in a browser, etc.). Zoom and pan until you find a view that displays the item and its content at its best. When ready to take a screenshot, press Command-Shift-3 for a screen shot of your entire screen, or, if you prefer, Command-Shift-4 for a screenshot of a rectangle you draw. See this Apple article for other useful options. https://blogs.esri.com/esri/arcgis/files/2016/06/MacImage.png For thumbnails of layers and web map content, use Command-Shift-4 and draw a rectangle of 286×190 pixels, or 200×133 pixels. Screenshots are saved as .png files on the desktop in Mac OS X v10.6 and later. They’re automatically named “Screen Shot date at time .png.” Go find your screenshot, double-click on it to edit it in the Preview app. For thumbnails of apps and story maps, maximize your browser, get the app to look the way you want, maybe click on the map to show a popup or chart, and press Command-Shift-3 to capture the entire screen. Go find your screenshot on the desktop, and double-click on it to edit it in the Preview app. Crop the image to cut out any extra stuff outside the browser window, and resize that image to 286×190 or 200×133 pixels. Save the image. Go back to your item page and upload the image. For inspiration on what makes for a good thumbnail, just look around the thousands of items in the Living Atlas, StoryMaps website, and the Esri Marketplace.

The Living Atlas Contributor App has recently been updated with enhancements! The app now supports vector tile layers and rule packages. On the Details page, two thumbnails are required for nomination (a standard size, 200 x 133 thumbnail, and a high resolution, 286 x 190 thumbnail). Some apps that access Living Atlas items display the standard size thumbnail, while others show the high-resolution thumbnail. This is in an effort to make Living Atlas items visually pleasing, regardless of the application used to access the item. Please see this blog post for more information on creating thumbnails for your items. The Tags page has been updated to use the same tags used by ArcGIS Online and the Living Atlas Web App. Also, the tags are not case-sensitive. Typing “oceans” or “Oceans” will both place a check mark in the box beside “Oceans” in the tag tree on the left. The name of the “Performance” page has been changed to “Settings”, to better reflect the criteria that is being scored in this section. This page now checks for the sharing capabilities, number of layers, and security settings of an item, along with displaying the item’s extent (if applicable). Draw time, pop-up, and delete protection scoring have all been removed. Delete protection was previously scored under Sharing. Even though scoring has been removed for draw time and pop-ups, curators will still be reviewing these criteria when an item is nominated for Living Atlas inclusion. Finally, the scoring has been revised to reflect the updates to the app. For more detailed information on using the app to nominate items for the Living Atlas, please visit the Nominate topic on the Living Atlas website.

In the latest release of Esri Demographics, sixty services have been updated with new content! This includes over one hundred new map image layers! All of the web maps and map image layers are available through the Living Atlas of the World on ArcGIS Online. Most countries will feature two web maps; average household size or total population and purchasing power per capita. Twelve European countries including Belgium, the Netherlands, Poland, and the United Kingdom now have more granular levels of geography, enabling more detailed analysis. In some cases, the data goes down to the block level, allowing for more meaningful comparisons between locations that ultimately lead to better decision making. All new maps will feature country level geography, enabling easy comparisons between two or more countries at the national level. Some countries also have new attribute names, so be sure to check the release notes associated with the countries you use. The Living Atlas of the World is the authoritative, curated, ready-to-use content available through ArcGIS Online. Contributed user and partner content, along with Esri content, compose the Living Atlas. This content can be used alone or in conjunction with additional data to help you complete your work more efficiently. To learn more, please visit our website and follow us on Twitter.

The new 2015 National Wetlands Inventory layers have been released! This includes both an imagery layer and a map image layer. The layers can also be seen in this web map. These layers are available through the Living Atlas of the World on ArcGIS Online. The pop-ups for each layer have been vastly improved and now include wetland classifications such as the system, subsystem, class, subclass, code, and even typical species where information is available. Water regime modifiers, special modifiers, water chemistry modifiers, and soil modifiers are also part of the pop-up and available as attribute fields. Wetlands provide a habitat for plants and animals while regulating water and building soil. The information contained in these layers is valuable to land use planning and efforts to conserve wetlands. This layer can be used alone or with other layers from the collection of landscape layers to complete a wide variety of mapping and analysis tasks, and the Extract Landscape Source Data tool can be used to download the layer’s source data. The Living Atlas of the World is the authoritative, curated, ready-to-use content available throughout the ArcGIS platform. Contributed user and partner content, along with Esri content, compose the Living Atlas. This content can be used alone or in conjunction with additional data to help you complete your work more efficiently. To learn more, please visit our website and follow us on Twitter.

The Living Atlas of the World Web App has been updated with enhancements! In addition to the theme filter, you now have the ability to filter by item type and region, too. You’ll also notice new categories and subcategories under the themes filter. Oceans is no longer a part of Landscape and is now a separate category in the Living Atlas of the World. You can now sign-in to the app. If you are already signed-in through another tab or window the app will recognize this and sign you in to the app. The region filter will be updated based on your ArcGIS Online profile. Items have been updated with badges that indicate the item type and if it’s premium or subscriber content. Also, the app is now part of the Living Atlas of the World website, providing you with a one stop shop for all things related to the Living Atlas. It can be accessed by clicking the Browse tab on any of the Living Atlas web pages.

Alicia, The Community Maps Program is a free program, where organizations that maintain basemap layers can have those layers published as part of our ArcGIS Online basemaps. Not only does this improve the quality of the maps, but it also provides the users and their stakeholders with a free, high performance, always available online map of their area of interest, which they can then use as the foundation for useful applications. The first step in the Community Maps Program is to identify the layers that you can contribute to the program. Do you have large scale data layers such as those listed here? Then you will apply to become a contributor through the Community Maps Contributor App. You’ll need an ArcGIS Online organization account to apply. You will only need to complete this step once.You will be notified when your application is approved. Please let me know if you have any questions, and I look forward to working with you! Thank you, Tamara Yoder Tamara Yoder | Training and Support Coordinator | Living Atlas of the World & Community Maps Program Esri | 380 New York Street | Redlands, CA 92373 | USA Work 909-793-2853, ext. 5028 | Cell 814-442-0579 | tyoder@esri.com | esri.com

Brady, Thank you for your question! While the Community Maps Program used the Local Government Information Model in the past for contribution, we've since evolved that model to better fit the needs of the program. We've made changes to optimize tasks such as data loading and map creation. If your data is already in the Local Government model it should be quick and easy to run the Community Maps Data Prep Tools. Sincerely, Tamara Yoder Tamara Yoder | Training and Support Coordinator | Living Atlas of the World & Community Maps Program Esri | 380 New York Street | Redlands, CA 92373 | USA Work 909-793-2853, ext. 5028 | Cell 814-442-0579 | tyoder@esri.com | esri.com

Walaa, I'm sorry, but I don't understand your question. Do you want to create scenes in ArcGIS Online and use them in ArcGIS Pro? Thank you, Tamara

Hi Jamison, The only obvious issue I can think of is that the tool only accepts polygons, so if your municipalities' limits are lines, then the tool will not work. If you send your source data and screen capture of the Admin3Polygons tool to tyoder@esri.com, I can troubleshoot it for you.

Malcolm, It would be best if you removed the point of interest label for that feature to eliminate the possibility of the feature being labeled twice. Thank you, Tamara Yoder

This is a great question, and the one that the ArcGIS Content Team hears most often. This is most likely due to the fact that the organization name entered in the second parameter is too long. The name can only be 20 characters in length, including spaces. This restriction was implemented to prevent the geodatabase from becoming too large. You can feel free to use an acronym or abbrevation for this parameter. We ask for this parameter in the Run Me First tool so we can easily reference the organization that contributed the feature(s) when working with the data in-house.
