shrug-l: Zoom map to the extent of a layer in Arcpy.mp

Fri Jun 2 14:53:18 EDT 2017

Thanks Jim and Janelle –

Yes, thanks i have come across those bits...

Migrating from arcpy.mapping to ArcGIS Pro
http://pro.arcgis.com/en/pro-app/arcpy/mapping/migratingfrom10xarcpymapping.htm

But that’s what is puzzling...

Why are certain layer-specific functions (Zoom To, Get Extent) NOT accessible from the Map object, but rather only from the MapFrame and Camera objects?

There is a context-menu function in the Contents tab to accomplish this and apply to the Map, but no ArcPy.mp approach to do the same.

Thanks again.

getLayerExtent (layer, {selection_only}, {symbolized_extent})

Returns a layer's extent for all features or only the selected features in a layer.

panToExtent (extent)

Pans and centers the MapFrame using a new Extent<https://urldefense.proofpoint.com/v2/url?u=http-3A__pro.arcgis.com_en_pro-2Dapp_arcpy_classes_extent.htm&d=DwMGaQ&c=-Q2oFtSeUeVdqcGrCCygxt6LResmVl0POOzRQwCZt0Q&r=FAqjIOx-pcrFksx2QCBU9vvFSJik7v39msusBaSUzSIdQZnp89FWM1k9-7mn_3ho&m=j8laF0QZ2eGrL5qrcVaTM5hoklOSiiFBYNAA4tBjBh4&s=ntDU_do_kyzcW-z5I1YbtKIta_BUoB7d85qVPW4mM_I&e=> object without changing the map frame's scale.

zoomToAllLayers ({selection_only}, {symbolized_extent})

Modifies the MapFrame view to match the extent of all layers or selected layers in a map.

Hi,  Saw this post from esri on geonet 5/3/2017.  Not sure if it’s what you’re trying to do.

“I just talked to an arcpy.mp developer and he said zooming on a Map View is not supported in arcpy.mp yet and probably will not be for awhile.”

Thanks Jeff –

But those apply to ArcGIS Desktop and ArcPy.mapping.

Looking for the equivalents in ArcGIS Pro and ArcPy.mp.

Thanks again.

Yes there is.

There's the getSelectedExtent method for a Layer<http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Layer/00s300000008000000/>:
•  getExtent ({symbolized_extent}) - Returns a layer's geometric or symbolized extent
•  getSelectedExtent ({symbolized_extent}) - Returns a layer's geometric or symbolized extent for selected features
A getSelectedExtent method <http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/DataFrame/00s300000003000000/> Dataframe<http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/DataFrame/00s300000003000000/>:
•  panToExtent (extent) - Pans and centers the data frame extent using a new Extent object without changing the data frame's scale
•  zoomToSelectedFeatures () - Changes the data frame extent to match the extent of the currently selected features for all layers in a data frame
Plus you can try these:
•  df.zoomToSelectedFeatures() - will zoom to the extents of the data frame to all selected features in the map frame
•  lyr.getSelectedExtent() - will zoom to to a selection set for a specific layer

Howdy SHRUG –

Anyone find a way to “zoom Map to the extent of a layer in Arcpy.mp” ?

There are many scenarios where this basic function, zooming to a layer or a selection, would be used, right ?
