Attributes

[Harshpanday]

Hello everyone,
How can I access the attributes of the Geodataframe that I use to add the agents?
In the project, I am working on I want to access the coordinates of each agent and use them. Is there a way I can do that?
I already did "set_attributes = True", but I am confused as to how can I access their attributes.

I will be very grateful if anyone can point me in the right direction.

With kindest regards,
Harsh Panday

I guess the attributes should be part of the GeoAgent object that you create, with the same name as the GeoDataFrame columns (except the geometry column which renames to shape)?

For example if your GeoDataFrame looks like this:

	name	geometry
0	Alice	POINT (1.00000 2.00000)
1	Bob	POINT (2.00000 1.00000)

Then the name should be available as agent.name and the geometry is agent.shape.

Yes you are correct. agent.shape is named due to historical reasons, since originally everything was based on shapely shapes. But definitely should be renamed to agent.geometry.

Thanks for your clarification, it helps a lot. I was always wondering why agent.shape was used instead of agent.geometry, and whether to just change it back.

I'll send a PR to rename to agent.geometry.

With #57, geometry is no longer renamed to shape. As I mentioned in #57 (comment), The current behavior is:

1. If we have the following data:

	name	geometry
0	Alice	POINT (1.00000 2.00000)
1	Bob	POINT (2.00000 1.00000)

then it gets loaded as agent.name and agent.geometry respectively.

2. If the active geometry of the GeoDataFrame is of other name, then it's also gets loaded as geometry. For example:

	name	home	work
0	Alice	POINT (1.00000 2.00000)	POINT (3.00000 4.00000)
1	Bob	POINT (2.00000 1.00000)	POINT (4.00000 5.00000)

If home is the active geometry column, then gdf.geometry and gdf.home are essentially the same thing. And it'll be loaded as agent.name, agent.geometry, and agent.work respectively.

Thank you for the clarification and changes.
