We\u2019re delivering important new functionality, including capabilities that are entirely new to mobile SDKs and enable a whole new category of GIS apps.<\/p>\n
As we move from 200.8 to 300.0, the focus is on expanding capabilities, with three major additions marking important milestones for the Native Maps SDKs: local scenes, building scene layers, and a brand new set of spatial analysis tools.<\/p>\n"},{"acf_fc_layout":"content","content":"
The Native Maps SDKs have supported 3D since 100.0 (some ten years ago), but always in a global context. This means using the WGS84 geographic coordinate system to display data, and for best performance, that generally means the data should also be published in WGS84 so it does not need to be reprojected on the fly. Reprojection consumes CPU resources, which on mobile devices can lead to faster battery drain. Publishing a separate copy of the data in WGS84 helps avoid that, but it often adds unwanted overhead.<\/p>\n
Enter local scene view<\/em>. This is a completely new UI component that you can add to your app, enabling you to work with a local scene, whether it comes from a web scene, an on-device mobile scene package, or created programmatically in code. A local scene can use any projected coordinate system, matching your published data and local workflows.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2963279,"id":2963279,"title":"A local scene,

The SDKs have long provided fast on-device analysis capabilities that work on local data, fully offline. These fit into four general categories:<\/p>\n To perform precise on-device spatial analysis you\u2019ve had two options: local server, or geometry engine. Geometry engine is perfect if you are simply working with discrete geometries. Local server enables more complex spatial analysis involving full datasets, elevation, and custom logic, but you need to be running Windows or Linux, and you need to install and maintain Local Server separately alongside your app.<\/p>\n To perform fast and\/or interactive analysis, you\u2019ve been able to use exploratory 3D viewshed and line-of-sight analysis overlays. These run on the GPU for excellent performance, but they have clearly defined limitations: crucially, they can only work on the data that\u2019s currently visible on screen, and only to the resolution of that data as rendered, plus the analysis is visual only (i.e. there\u2019s no output you can make decisions from). And they require a 3D scene view to be visible to use them.<\/p>\n That changes today. The new spatial analysis tools add a fifth category to the list above, combining the best of both worlds: precision and speed.<\/p>\n They work with your source data at its full resolution, and while they use the GPU for optimized lightning-fast execution, it’s an entirely dedicated GPU pipeline, separate from the one used to render data to screen. The APIs also output precise analysis results which you can use however you like: you can display them, use them for further analysis, interrogate them to make decisions, or simply save them to disk.<\/p>\n"},{"acf_fc_layout":"content","content":" At a high level, this is how you use the new APIs:<\/p>\n The analysis operations can be the Viewshed or Line-of-sight tools, or any of the map algebra operators, or some combination of these.

Crucially, that pipeline is not executed until you explicitly request the result. In technical terms, we are combining lazy evaluation<\/em> and operation fusion<\/em> on your analysis operations. This approach allows the APIs to optimize analysis by combining operations before execution, reducing both processing time and memory use by avoiding the need to calculate or store intermediate results.<\/p>\n One of the most noticeable aspects of this approach is that you can simply modify parameters that are used anywhere in your sequence of operations, and the changes are immediately reflected in the optimized pipeline. For example, if a line-of-sight observer moves, simply update the location you provided when you defined the analysis, and the next time you ask for the analysis result, it will reflect this updated location. If you\u2019re using the analysis overlay to display your analysis on a map, the overlay display will automatically update the moment you provide the updated location.<\/p>\n In this video below, we’re setting up a number of line-of-sight analyses from a single observer, and by updating that one observer location, all analyses are updated (and notice how quickly!).<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2963293,"id":2963293,"title":"Line of sight timings","filename":"LOS-Timings-cropped.gif","filesize":6851965,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/04\/LOS-Timings-cropped.gif","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/developers\/announcements\/whats-new-in-arcgis-maps-sdks-for-native-apps-300-0\/los-timings-cropped","alt":"Line of sight speed","author":"3811","description":"","caption":"Testing the performance of the line-of-sight analysis - 1000 sightlines calculated in 5ms.","name":"los-timings-cropped","status":"inherit","uploaded_to":2963262,"date":"2026-04-21 02:33:51","modified":"2026-04-21 02:35:00","menu_order":0,"mime_type":"image\/gif","type":"image","subtype":"gif","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":800,"height":460,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/04\/LOS-Timings-cropped-213x200.gif","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/04\/LOS-Timings-cropped.gif","medium-width":454,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/04\/LOS-Timings-cropped.gif","medium_large-width":768,"medium_large-height":442,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/04\/LOS-Timings-cropped.gif","large-width":800,"large-height":460,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/04\/LOS-Timings-cropped.gif","1536x1536-width":800,"1536x1536-height":460,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/04\/LOS-Timings-cropped.gif","2048x2048-width":800,"2048x2048-height":460,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/04\/LOS-Timings-cropped.gif","card_image-width":800,"card_image-height":460,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/04\/LOS-Timings-cropped.gif","wide_image-width":800,"wide_image-height":460}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":" Probably the best way to understand these new spatial analysis APIs is to see them in action.

You can still use the same 100.x license string with all 100.x and 200.x SDK releases, but to use the 300.x SDKs you will need new 300.x license strings.<\/p>\n If you\u2019re using the free Lite license, simply get a new 300.x Native Maps SDK Lite license string from My Esri<\/a>.\u00a0 You can retrieve your Lite license string from the “ArcGIS Maps SDKs for Native Apps License Strings” card on your My Esri dashboard’s Overview page.\u00a0 If you see a message that states “Your active ArcGIS Organizational account is not enabled for esri.com websites”, please contact your ArcGIS org’s administrator to enable access -or- determine an approach for distributing Lite license strings.<\/p>\n If you\u2019re using Basic, Standard, or Advanced license strings (or extension license strings), you will need to obtain 300.x license strings before you can deploy your apps using the 300.x SDKs. You can obtain these from Esri customer service or your local distributor. These new strings are issued at no cost if you\u2019re current on maintenance.\u00a0 If not, please contact your Esri account manager or Esri customer service.<\/p>\n"},{"acf_fc_layout":"content","content":" While local scene, building scene layer, and the new spatial analysis tools are the key new capabilities of the 300.0 SDKs, the team has been hard at work on a whole range of new and improved functionality.

Shared templates are commonly used in utility networks but can be useful in any number of data creation workflows. Preset templates let you place a number of new features in a predetermined pattern around a single location (for example, placing a fixed arrangement of picnic tables and trash cans around a point), while group templates let you apply complex predefined builder rules using a base geometry (for example, placing a trailhead, mileposts, and benches at preconfigured intervals along a polyline).
