ArcGIS Online - Besoin d'empêcher les utilisateurs de zoomer trop près ou trop loin

RayCrew

<\/HEAD>

Ni les applications de cartographie Web ArcGIS OnLine ni les cartes Web ne permettent aux auteurs de limiter jusqu'où les utilisateurs peuvent zoomer en avant ou en arrière. C'est possible s'il y a une carte de base mise en cache, mais pas autrement. Définir des dépendances d'échelle et des limites sur les services REST et les couches ne supprime pas ce besoin. Cela empêchera l'affichage des couches, mais permettra toujours des échelles qui peuvent causer de la confusion, de la frustration et des problèmes aux utilisateurs. Définir une échelle et une étendue par défaut ne résoudra pas non plus ce problème. Cette fonction était possible dans une ancienne plateforme ESRI, ArcGIS for Flex, en spécifiant des LODs.<\/P>

Exemple 1 : Une carte mondiale montrant la population totale par pays permet à un utilisateur de zoomer jusqu'à 1:1,000. À cette échelle, l'utilisateur sera très probablement profondément à l'intérieur du polygone d'un pays, ce qui l'obligera à faire plusieurs panoramiques et zooms pour voir un autre pays à comparer.<\/P>

Exemple 2 : Une carte montre les taux de pauvreté infantile par blocs de recensement dans trois comtés du sud-ouest de la Virginie. Un utilisateur peut dézoomer jusqu'à 1:73,000,000 pour voir tout le pays. À cette échelle, les données du recensement affichées ne seront pas visuellement évidentes et difficiles à retrouver.<\/P>

<\/P>

Ceci est similaire à une autre idée soumise en 2013<\/A>, cependant, cette demande est plus simple. Je demande juste des limites d'échelle sans verrouillage du panoramique, une fonctionnalité plus difficile à implémenter.<\/P><\/BODY><\/HTML>

I also started a discussion on GeoNET about this:

It would be good to have this kind of publishing control for specific services, especially if the data behind the service was developed at scale and should be viewed the same way. Visible scale levels may not always be appropriate. However, I can see this presenting a problem for a web map consuming multiple services each with their own level constraints.

Otherwise scale level navigation can be controlled at the application level.

Yes, please. I'd also like to prevent people from panning to irrelevant areas. We're about to publish some proposed zoning changes in Knox County, TN via ArcGIS Online. There's no need for the map viewer to visit North Carolina, Washington State or even Japan.

We have a story map in which the data is unsuitable to be viewed beyond a certain zoom level. While we can make the layer disappear at certain zoom levels , the ideal would be to not allow the user to zoom in past a certain point.

This would be very useful as well as limiting the panning area.

I agree it would be great to be able to add this ability to lock the min and max zoom level in the map viewer of arcgis online and portal or have this as an option in ALL mapping applications. I currently have a cached base map with 10 scale levels that I use on other maps and I have a map that I only want to show the scale levels 2 through 4. After that the data becomes unusable. I am now forced to set up another cached service of the EXACT SAME base map that I already have with 3 of the exact same scales that I already have, eating up more resources on my server. If there was just another simple setting on in map viewer of arcgis online right under set visibility range on base maps to set max zoom extent and min zoom extent this would save a lot of additional configurations.

I'm glad to see this is "Under Consideration". It seems like a really basic feature, I'm surprised it's not available. Most maps show data that only makes sense in certain scales and for one specific area.

In my case I have a web map with a custom base map (cached tiles and hosted layer) with three zoom levels. So my basemap has edges and ideally the user wouldn't be allowed to go past those. So locking panning extent would be really useful as well. Visibility range is not enough, because if the user goes outside of that they are left with a blank map, which is disorienting and easy to get lost in.

Esri, why is this taking so long? Why was it not implemented from the beginning? Will this be added soon?

Is there any update to this feature that is supposed to be "Under Consideration"? I need it for my park amenity map because I don't want the map user to pan out of the park area.

NaomiCampoy

Any updates? It's been 8 years since this post.

Hi All,

Now, for 2D maps, you can limit the scale range that users can zoom to. It has been released on ArcGIS Online in February 2025, will be released on ArcGIS Enterprise 11.5 and ArcGIS Experience Builder Dev Edition 1.17.

The map bar shows the level of detail(LODs) of the basemaps in the connected maps.

Thanks,
