[Ger-Poland-Volhynia] help with navigating the sggee site please

[kitchur at mymts.net]

A Google search for Heraldowka Zhyomyr Ukraine takes me to an Sggee page of 

https://www.sggee.org/research/Gazetteer_Volhynia.pdf 

from there I'm lost, how do I find this map of Frank Stewner's? 
I've gone to research, maps and villages. 
https://sggee.org/SGGEE2009/research/village_maps.html 
searched various links there can't find g-4 map or Heraldowka 

What am I doing wrong? 

thanks
