RCE – wie man den Ausdehnungsbereich für die esri World Imagery Basiskarte konfiguriert

Question

Ich habe RCE Basiskartenebenen in der Beispiel-webmap.json-Datei konfiguriert. Die Ebenen umfassen meinen lokalen, auf Bundeslandebene angepassten Basiskartendienst und die esri World Imagery Ebene. Beide laden in der RCE-Karte, aber die Ansicht ist standardmäßig auf den weltweiten Ausdehnungsbereich der esri-Bilder eingestellt, wenn die Karte geöffnet wird. Wie kann ich den Ausdehnungsbereich so konfigurieren, dass beim ersten Laden der Karte auf meine Bundeslandansicht gezoomt wird? Ich habe bereits einige Dinge in der map.js-Datei versucht, aber bisher ohne Erfolg. Außerdem habe ich versucht, die Karte zuerst im Portal mit dem richtigen Zoomlevel zu konfigurieren und dann das JSON in eine neue benutzerdefinierte webmap.json-Datei zu kopieren, aber der von mir im Portal festgelegte Ausdehnungsbereich wird nicht beibehalten. Vielen Dank für jegliche Vorschläge.<\/P>

Hi Amit,

I was able to solve the problem. Even though I could not add a web map to the Editor through the portal interface, I was able to simply add the item id to the config.json file and the extent problems were corrected. It is interesting that adding the json for the exact same webmap as a local webmap has a different result and will not preserve the extent of the portal map. Thanks again for your help.

Hi Amit,

Thanks for your reply. The Event Editor is version 10.7.1. A problem seems to be that although the editor item is registered on the portal and can be launched from the portal item by clicking the "View Application" button, there is no GUI edit button or any other option for adding a map to the application through the portal tools. When the application launches, the "Basemap" gallery dropdown is empty. Also, clicking the "Web Map" button on the left side of the ribbon does show existing folders that have been created on portal but it will not show any web maps that have been created within those folders. This may answer your question as to why we have used the method of adding local webmaps to the webmap.json file. Can you offer a suggestion as to why we do not seem to have a full connection to the portal interface with the application? In the config.json we have supplied the portalUrl and the portalAppId. By the way, our LRS service and LRS functionality works fine. We have our own LRS service as well as our own basemap service. However the local basemap service does not supply imagery, so we also include the esri world imagery service as a second basemap layer. Although the coordinate systems of the imagery service and our local services are different, they overlay with no problems. The only user issue is the annoying need to zoom into the state level from the whole world imagery view every time the app opens.

Thanks,
Elizabeth

Hello Elizabeth,

It sounds like you've chosen to author your Event Editor webmap using a local file on the web server where the app is deployed. May I ask what version of Roads and Highways you are using? It also sounds like you have portal running so I might also ask whether there is any specific business reason to use the local webmap as opposed to simply authoring your webmaps on portal?

Outside of those questions, the LRS service you are using for webmap configuration usually defaults to the zoom scale the MXD you published from was set to. You might want to check on that MXD. Additionally, do you have any feature layers in your map without a spatial extent set? Sometime empty event layers can cause this if you set the initial extent to the full map extent:

You've likely already found our resource document for this topic but I'm adding it to this thread just in case. Authoring Webmaps for Event Editor

Incidentally, extent (among other things) in Event Editor can also be controlled via URL parameters. https://enterprise.arcgis.com/en/portal/latest/use/use-url-parameters.htm

And finally, our resource document on smart launching Event Editor through URL parameters: https://enterprise.arcgis.com/en/roads-highways/latest/event-editor/smart-launching-event-editor-through-url-parameters.htm

Hope that gives you a good starting point to resolve your extent issue.
