Add support in ArcGIS Urban Online and Enterprise for on-the-fly re-projections using US Standard units in local Urban Models
Hello ArcGIS Urban Team,
For the option: Urban now supports coordinate systems other than Web Mercator
https://www.esri.com/arcgis-blog/products/urban/announcements/new-coordinate-systems-support-in-arcg...
Can you please explain a little more about these technical limitations listed below from you blog post and when they will be resolved for the Online and Enterprise versions of ArcGIS Urban?
For our case Urban will be using these US Standard units like you mentioned in your recent what's new in Urban February 2024:
EPSG:2228 NAD83 California Zone 4 ftUS
EPSG:6360 NAVD88 Height ftUS
"In a local urban model, you cannot use certain functionality due to technical limitations. The following are not available in local urban models:
Default 3D base layers (for example, 3D OSM buildings and trees)
Default basemaps
Default elevation layer
Street-level imagery
ArcGIS Living Atlas indicators"
Some functionality is unavailable in local Urban Models because Esri's 3D web platform only supports on-the-fly projection between coordinate systems for non-cached layers (e.g., hosted feature layers).
The 3D base layers, the default basemaps, the default elevation layer, and the Living Atlas indicators are provisioned as cached layers in either the Web Mercator or the WGS84 coordinate system. They can only be displayed in global scenes.
The street-level imagery feature builds upon the Mapillary platform, which only supports WGS84 coordinate systems.
All of the above data items display well in global scenes and urban models, regardless of whether the data is in the Web Mercator or WGS84 coordinate system. However, these items don't work in local scenes and urban models. This is an overall limitation of Esri's web 3D platform, and I'm unaware of any plans to change this behavior.
There is no difference between Urban on ArcGIS Online and Urban on Enterprise regarding on-the-fly reprojections between global and (projected) coordinate systems, web scenes, and urban models. This is an overall platform limitation.
There definitely exist workarounds, like publishing your own 3D base layers, base map, or elevation layer. For a more profound analysis of your use case, including possible workarounds, I'm happy to connect you with one of our urban planning consultants. Just send me a direct message if that would be of interest to you.
If you'd like to give the need for on-the-fly reprojections more weight, please feel free to submit an Idea on either the ArcGIS Online or ArcGIS Enterprise Place, here in the Esri Community.
I talked with @SilviaCasas and @MichaelVanDenBerg on the exhibit hall floor at the 2023 UC in San Diego and sat in on Silvia's session listed below.
Silvia let me know about a potential option to use Urban in Enterprise 11.3
ArcGIS Urban: An Introduction and What's New
https://registration.esri.com/flow/esri/23uc/uc-2023-ps/page/proceedings/session/1671557778574001Ky2...
We are working with our local esri team in the very beginning/training stages with our licenses of ArcGIS Urban and City Engine. (prep-prep-prep).
We are using Enterprise 11.1 to process our Nearmap aerial imagery products (DEM/DSM/LAS/SLPK) in our local projected coordinate systems to use with urban as you mentioned for our own sources.
- 3D Base Layers
- Base maps
- Elevation Layers
Will do on the idea item.
Thank you,
-Bill
