Zoom in at 1:5 000 at x : -73,512864 and y: 45,659871

Jean-SimonLevert — Mon, 20 Feb 2017 20:02:23 GMT

I have

x : -73,512864

and

y: 45,659871

What is the code i need to put in ArcGIS Pro Python to zoom in directly at that GPS place and to zoom it at 1:5 000?

Anyone can help?

Creating a point can be done easily, even by adding a gps point waypoint. If you want to do this using python, then the arcpy module is what you need but there is little there to enable zooming, so it sounds you will need to decide what root you want to go and whether the zooming bit is critical especially if you can set the map frame extent apriori

Is there anyone that could show me a code that I could use to achieve my task?

You need to work with the Camera class. When working with the Camera class, it is very important to read and remember:

The ArcGIS Pro application integrates 2D and 3D display and, therefore, the Camera object is used to control both the scale and extent for 2D maps and the camera position for 3D maps in a MapFrame.

Since MapFrames only exist as Layout elements, the majority of the Camera class properties and methods don't do anything when working in a Map.

So, you will need to have a MapFrame in a Layout, and then you can use the MapFrame camera to control center (X, Y), scale, etc...

-----------------------------------------------------

import arcpy
aprx = arcpy.mp.ArcGISProject("CURRENT")
m = aprx.listMaps()[0]
lyr = m.listLayers()[0]
lyt = aprx.listLayouts()[0]
mf = lyt.listElements()[0]
mf.camera.setExtent(mf.getLayerExtent(lyr, False, True))

-----------------------------------------------------

I found that this will zoom out until i see everything.

Im still looking for a way to get to x : -73,512864 and y: 45,659871 and to zoom to 1:5 000.

Have you looked at the Camera object properties?

Are you using a 2d or 3d view... there is some discussion within the help topics on camera particularly the sections on 'extent'

Jean-SimonLevert — Wed, 22 Feb 2017 01:40:49 GMT

I am using 2d view. Even with the topic on camera, i can't find the best way to make it possible with Python. Normaly i code with WinAutomation. Its so simple, it took me 10 min to set up an Automation that add the x,y on the search zone and scale zone in ArcGIS Pro without any click within 3sec and the zone is printed in pdf in that time... Im just looking to learn how to do things with Python.

Yes... It think the python access is probably designed with analysis in mind. Navigating the whole properties object can be a bit much. For example in the MapFrame topic there are vague references to the setting of local and global view. I suspect you are in a global view since you are probably off the coast of Africa, south of Ghana as you seem to reference, which suggests that you are in some sort of web projection, like web Mercator and not in a coordinate system that is using decimal degrees. Your coordinates are indeed just east of me and not in Kazakshtan as would an omission of the -ve in longitude. I wouldn't expect python to perform your required task as simply as other interfaces since I suspect it is not designed for this. Good luck

Try this:

import arcpy

aprx = arcpy.mp.ArcGISProject("CURRENT")
lyt = aprx.listLayouts()[0]
mf = lyt.listElements()[0]

SR = mf.camera.getExtent().spatialReference
pt = arcpy.PointGeometry(arcpy.Point(-73.512864, 45.59871),
                         arcpy.SpatialReference(4326))
pt = pt.projectAs(SR)

mf.camera.scale = 5000
mf.camera.X, mf.camera.Y = pt.firstPoint.X, pt.firstPoint.Y

This is the answer!

Thx alot! Work perfectly!

Those code lines work perfectly when I want to zoom in my layout.
I try to work the same code lines to zoom in in the map instead of the layout.

I tried to replacelyt = aprx.listLayouts()[0]

for

lyt = aprx.listMaps()[0]



But nothing works... anyone can help me?

It isn't possible to do what you want. You need to control the camera, and you can only access the camera from a map frame. A Map let's you access the Default Camera, but it is the Default Camera and not the active camera.

The explanation for this behavior/limitation lies in the Migrating from arcpy.mapping to ArcGIS Pro—ArcPy | ArcGIS Desktop documentation:

New Map, MapFrame, and Camera objects replace the role of the data frame
The ArcGIS Pro framework has introduced new capabilities that affect how you interact with map displays and therefore new objects are being introduced. These new Map, MapFrame, and Camera objects each serve a specific role and are tightly integrated with one another.
A Map in ArcGIS Pro represents a collection of tabular and symbolized geographic layers and also persists information such as coordinate system, default views of the data, and various other metadata. The only way to visualize the contents of a map is in a map view, as a tab in the application with its own table of contents, or in a mapframe on a page layout. The same map can be displayed in multiple map views or map frames. If a layer is added to a map, all map views and map frames that reference that map will display the added layer. If you want a different collection of layers or tables to be displayed in different views, you will need to build and use different maps.

The key line is, "The same map can be displayed in multiple map views or map frames." I believe it is this reason that Esri has used to not allow access to the camera in the Map object.
