Get current scale of map

MattiasWesterberg — Fri, 17 Feb 2023 12:11:10 GMT

hi,

I set the scale of my map like this:

this.MyMapView.Map.MinScale = 2500000;

But how do i get the current scale of my map after i have zoomed to another scale?

Thanks in advance.

Hello,

I think you want to try:

double scale = this.MyMapView.MapScale;

To set the scale, I would use:

await this.MyMapView.SetViewpointScaleAsync(scale);

Best regards,

Volker

To get current scale of the map use `GeoView.GetCurrentViewpoint` and with ViewpointType as `CenterAndScale`

What I want to do is to add a Graphic object and give it ZIndex 1.

Then I want to add a FeatureLayer for a shapefile and set its ZIndex to 2.

And then i want to add another Graphic object and give it ZIndex 3.

I'm not quite following the relationship between mapview scale and ZIndex on features on your features and graphics, but having said that, you can only control the ZIndex within a single graphics overlay, and graphics always goes on top of feature layers, so there's no way to have a feature in-between two graphics.
