How to have GDAL print layers of GeoPDF AND say which are raster vs vector

My Objective: I would like to use GDAL to convert a GeoPDF. I want the vector layers as shp files and the raster layers as tif files. I want to do this in a programmatic way.

Edit: In reality, I want to do this with many geospatial PDFs. I’m prototyping the workflow using Python, but it will probably end up being C++. (End Edit)

The Problem: Naturally, the command to convert a vector layer differs from a raster layer. And I don’t know (again in a programmatic way) which layers are vector and which are raster.

What I’ve Tried: First, here is my sample data https://www.terragotech.com/images/pdf/webmap_urbansample.pdf.

gdalinfo webmap_urbansample.pdf -mdd LAYERS

gives the layer names:

...
Metadata (LAYERS):                           
  LAYER_00_NAME=Layers                       
  LAYER_01_NAME=Layers.BPS_-_Water_Sources   
  LAYER_02_NAME=Layers.BPS_-_Facilities      
  LAYER_03_NAME=Layers.BPS_-_Buildings       
  LAYER_04_NAME=Layers.Sewerage_Man_Holes    
  LAYER_05_NAME=Layers.Sewerage_Pump_Stations
  LAYER_06_NAME=Layers.Water_Points          
  LAYER_07_NAME=Layers.Roads                 
  LAYER_08_NAME=Layers.Sewerage_Jump-Ups     
  LAYER_09_NAME=Layers.Sewerage_Lines        
  LAYER_10_NAME=Layers.Water_Lines           
  LAYER_11_NAME=Layers.Cadastral_Boundaries  
  LAYER_12_NAME=Layers.Raster_Images         
...

I know to look at the data which are vector and which are raster, but I don’t know how to parse this information to know whether to use ogr2ogr or gdal_translate to do the conversion.

Then I thought I could use ogrinfo and just diff all the layers to deduce which ones are raster, but ogrinfo gives me:

...
1: Cadastral Boundaries (Polygon)
2: Water Lines (Line String)
3: Sewerage Lines (Line String)
4: Sewerage Jump-Ups (Line String)
5: Roads
6: Water Points (Point)
7: Sewerage Pump Stations (Point)
8: Sewerage Man Holes (Point)
9: BPS - Buildings (Polygon)
10: BPS - Facilities (Polygon)
11: BPS - Water Sources (Point)

So there’s not a one-to-one correspondence with the way these are output.

So my question is: Does anyone know how to have gdal print the GeoPDF layers and indicate which are raster vs. vector? Or is there another way to infer this?

Thanks!
