Hi,

The task is to restrict user to go to zoom out.

I wondering if ESRI has "official" zoom level/resolution/scale defined in some documentation. I understand - LODs are settings (could be changed). But what are "out-of-the-box" LODs settings?

The official help provides only 5 levels (are they the same as for default map (if we do not put LOD in Map constructor))

Map (legacy) | API Reference | ArcGIS API for JavaScript 3.18 

I found also How can you tell what map scales are shown for online maps? | ArcGIS Blog 

lods: [
{ "level": 0, "resolution": 9783.93962049996, "scale": 36978595.474472 },
{ "level": 1, "resolution": 4891.96981024998, "scale": 18489297.737236 },
{ "level": 2, "resolution": 2445.98490512499, "scale": 9244648.868618 },
{ "level": 3, "resolution": 1222.99245256249, "scale": 4622324.434309 },
{ "level": 4, "resolution": 611.49622628138, "scale": 2311162.217155 },
{ "level": 5, "resolution": 305.748113140558, "scale": 1155581.108577 },
{ "level": 6, "resolution": 152.874056570411, "scale": 577790.554289 },
{ "level": 7, "resolution": 76.4370282850732, "scale": 288895.277144 },
{ "level": 8, "resolution": 38.2185141425366, "scale": 144447.638572 },
{ "level": 9, "resolution": 19.1092570712683, "scale": 72223.819286 },
{ "level": 10, "resolution": 9.55462853563415, "scale": 36111.909643 },
{ "level": 11, "resolution": 4.77731426794937, "scale": 18055.954822 },
{ "level": 12, "resolution": 2.38865713397468, "scale": 9027.977411 },
{ "level": 13, "resolution": 1.19432856685505, "scale": 4513.988705 }

Piterson,

   The way I always use is to copy this url into the addressbar of a browser and copy the lods of the results:
