What’s New in ArcGIS Online (December 2017)

What’s New in ArcGIS Online (December 2017)

ArcGIS Online has just been updated with the following new features and enhancements. This release includes a more flexible user experience for managing and discovering content, Insights for ArcGIS, administrative enhancements, and other improvements throughout the site.
For additional information see the What’s new help topic or ArcGIS blog posts specific to this release.

*
User experience

Start Page
You can specify the start page that you first see when you sign in to your account. The setting is managed in your Profile.
The specified page appears each time you sign in to your site. For example, set your start page to Gallery to go directly to your organization’s gallery page, or set your start page to Map to open the Map Viewer automatically after signing in. See Start page for details.
*
App Launcher
Administrators can now make web apps available to organization members by adding apps to the app launcher. The app launcher appears in the upper right next to Search after signing in.
Members can personalize their view of the app launcher by dragging and dropping apps to change the order in which they are displayed.
*
Item Status
Items can now be marked as authoritative or deprecated in the item settings. Administrators and content curators in your organization—those with privileges to update organization content—can now designate items as Authoritative. Users can deprecate items they own. Setting the status makes it easier for members of your organization to find reliable, authoritative items while discouraging the use of items that are not as reliable or becoming out-of-date. Items with these status indicators are identified by a corresponding badge on the item page.
The Status filter can be used when members search or browse for content. Organization members can also restrict layer searches to authoritative layers when authoring maps using the Map Viewer. The Authoritative status is currently only visible within your organization, Deprecated status is also visible outside your organization.
*
Item information
A new status bar and interactive checklist on item pages help item owners and administrators improve item information, making it easier for others to find, understand, and use their items.
As item details are completed, the status bar shows the current item information completion status, and offers suggestions for improvement. See Item information for more details.
*
Mobile devices
ArcGIS Online has been enhanced to better support mobile devices. Open layers in Map Viewer using the new open link on the layer’s item page. Sign in with your enterprise or social network credentials and get help with your password and user name.

*
Insights for ArcGIS

Insights for ArcGIS is a web-based, data analytics workbench that allows you to perform iterative and exploratory data analysis. A new version is now available for ArcGIS Online, previously Insights was only available with ArcGIS Enterprise.
Using interactive linked cards, you can gain new discoveries about your spatial and nonspatial data. Linked cards allow you to click on a map or chart and see related data light up on another card. In the example above, crimes are explored by type, volume, and density to see if patterns change over time.
For more information, see the Insights for ArcGIS website or Insights for ArcGIS help.

*
Map Viewer

Map Viewer is a built-in app that enables you to view and author maps, navigate, see map details, edit, perform analysis, and more (depending on your privileges). New for this release:
Analysis tools include a new Find Centroids, allowing you to find the geometric center of multi-point, line, or area features.
Aggregate Points and Summarize Within have a new option to generate custom square or hexagon bins instead of summarizing your data within an input area layer.
Light up your map with a new Firefly symbol set. A firefly point symbol is a dot with a colorized glow effect, useful for creating dramatic thematic maps. These symbols are especially effective when used with the World Imagery (Firefly) basemap.
See more Firefly symbols and basemaps in the Living Atlas of the World.
You can now use geometric operations in Arcade expressions defined for smart mapping styles, labeling, and pop-ups. Use advanced functions to normalize by area, test spatial relationships, compute distances between defined areas, and more.
You can now update the URL of layers in your map from HTTP to HTTPS, or from staging versions of your ArcGIS service layers to production versions. This is available via the Settings tab for the map item. ArcGIS Online inspects each layer in the map. If any layers use HTTP, ArcGIS Online attempts to make a request to the same layer using HTTPS, and then updates the map and any associated layer items you own or administer. If a layer does not support HTTPS, you are notified and the layer URL is not updated. See Layer Settings for more details.
Arrows are now available to indicate direction when styling line features. See Change symbols for more information.
You can now add GeoJSON files to your map. GeoJSON is a widely used open standard format for encoding a variety of geographic data structures in JavaScript Object Notation (JSON) format. See Add layers from files.

*
Scene Viewer

Scene Viewer is an app built into ArcGIS Online for creating and interacting with 3D scenes. New for this release:
You can now measure distances in 3D between two points in Scene Viewer. Choose different measuring units and leverage interactive laser lines to calculate the direct and vertical distances in your scenes. See Measure your scene.
Scene layer performance has significantly improved in this release. Buildings and integrated mesh scene layers now load faster using the correct priority order. Additionally, when zooming to scene layers, data is temporarily cached enabling the layers redraw much faster.
3D symbols from ArcGIS Pro can be used in your scene via style files published from Pro. In addition, organization Administrators can now configure custom web styles for Scene Viewer.
Other enhancements in Scene Viewer include the inclusion of 3D ArcGIS Marketplace subscription content, and 3D mobile support (still in experimental phase).

*
Data collection & management

You can now use CSV and Microsoft Excel files stored in Microsoft One Drive and Dropbox to publish hosted feature layers. If you update the the data in the file on the cloud drive, you can overwrite the data in the hosted feature layer using the updated cloud data. Google Drive, including Google Sheets, will be supported soon after this initial release. For more information, see Add and publish files from a cloud drive.
Administrators and owners can now append data to layers in existing hosted feature layers without needing to overwrite the entire hosted feature layer.
You can now define an area of interest for hosted feature layer views to limit access to features within a particular area.
New editing options are available for hosted feature layers and hosted feature layer views, providing more fine-grained control over what operations editors can perform.
After enabling editing, choose the editing capability allowed on the feature layer. See Manage editor settings for details.

Point cloud smart mapping in 3D with Scene Viewer

Point cloud smart mapping in 3D with Scene Viewer

Today, I want to discuss how you can use Scene Viewer to style and configure point clouds directly in your browser, interactively, and intuitively, leveraging the power of smart mapping smart defaults and color ramp sliders. Cities across the world are leveraging the power of point clouds to visualize and present their 3D data, and the smart mapping styles in Scene Viewer give you the ability to customize your visualizations of point cloud data to suite the unique needs of your projects. All you need to do is sign in to ArcGIS Online and you’re on your way.


Explore point cloud styles

To visualize point cloud scene layers, I can choose one of the different smart mapping drawing styles available based on the point cloud attributes: True Color, Class, Elevation, and Intensity. Each style has its own strengths and value depending on the scene I’m trying to create. For example, I can use the Elevation style to explore and understand the changing elevation of the structures and terrain in my scenes.

Hint: The smart mapping styles also include an easy-to-use slider that lets me manually change the point size from smaller to larger and vice versa. Furthermore, if my point cloud layer doesn’t match the terrain, I can apply an offset to my point cloud layer to align it better.

Show your true colors

If I’m interested in displaying the realistic look and feel of my city or landscape, I would choose the True Color style because it displays point cloud data with the true RGB values collected in the LiDAR remote-sensing process. For example, this scene of Mile High Stadium in Denver, Colorado really got my attention. The scene showcases point cloud data created by Merrick and with the True Color style chosen, I can even clearly see the team name “BRONCOS” spelled out in the end zone!

Can I see my point cloud data classified?

With the Class style, I can assign a specific color to the classes in the point cloud data defined in the collection process.  This is helpful when I want to emphasize and distinguish the most important elements of my scene, such as buildings, plants and vegetation, and ground.  When I open the Class style, I can see what classes are available by looking at the list and also in the legend.

Hint: If I turn the “Modulate using intensity “option on, I can shade the color of the points based on the intensity value (see the Intensity style below). This improves depth perception and perspective of my point cloud scene when many nearby points have the same color. By adding this option and playing around with the class colors, I can see much more detail, such as the roads and roof structures.

Also, in case you’re wondering what those trees are doing on the highway, please don’t call the forest service. They’re actually cars. However, LiDAR scanning is not a perfect science and sometimes automated classification fails and puts some points in the wrong category.

What I’d really like to see is the elevation of my points

I chose the Elevation style to visualize this Helsinki scene I created to emphasize the higher areas and structures. Knowing the elevation of buildings and terrain throughout Helsinki is very important from an urban planning, environmental, or industrial perspective. For example, if I am in the shipping or utilities industries, I may want to focus on structures higher than a certain height, such as cargo cranes or power lines. I can adjust the Elevation style sliders to make the higher areas and structures stand out more.

What is intensity in point clouds?

Using the Intensity style is another great way to see the fine details and textures of Helsinki’s urban landscape. Intensity is a measure of the return strength of the laser pulse that generated the points in the point cloud data collection process. With the Intensity style on, I can get even more detail and contrast in my scene by adjusting the slider to match the distribution of point values.

First, I drop down the top slider bar to 190 intensity value. Then I set the maximum value to 200 to reset the distribution of the color ramp.

Now I can really see the contrast between the buildings, streets, trees, and canals. All that’s left for me to do is pick out a pleasing color ramp and my scene is finalized.

I encourage you to explore for yourself the power of smart mapping with point clouds in Scene Viewer. To learn more about point cloud smart mapping styles, see style point clouds. And feel free to share your own cool scene creations and comments.
