One good and simpler alternative is to use "Internet in a Box" .
Installation is simple, it has most of the stuff you will need, check out the FAQ. You have 3 choices to select when you run the install script: Min, Med, or Big. Checkout the software in each bundle here. You need to scroll down. A screenshot of the list is below:
You can load up contents using USB thumbdrive or harddisk.
The entire world map can be downloaded from Openstreetmap from the admin console, you can select the region to download to save space. The entire world map is about 150Gb. Here is the rendering from the downloaded file for North America:
Here are various screenshots from Admin page and the various software:
curl d.iiab.io/install.txt | sudo bash
Here is the link to the site, as of this writing, the latest version is 7.1.
Here is the script from install.txt:

# To install Internet-in-a-Box (IIAB) 7.1 / pre-release onto Raspbian Buster,
# Ubuntu 18.04 or Debian 10, run this 1-line installer:
#
# curl d.iiab.io/install.txt | sudo bash
# 1. WARNING: NOOBS IS *NOT* SUPPORTED, as its partitioning is very different.
# On a Raspberry Pi, you need to INSTALL THE LATEST VERSION OF RASPBIAN:
# https://www.raspberrypi.org/documentation/installation/installing-images/README.md
# To attempt IIAB 7.1 on another Linux see the full/manual instructions:
# https://github.com/iiab/iiab/wiki/IIAB-Installation#do-everything-from-scratch
# 2. An Ethernet cable is HIGHLY RECOMMENDED during installation, as this is
# more reliable than Wi-Fi (and faster!) But if you must install IIAB using
# Wi-Fi not Ethernet, remember to run 'iiab-hotspot-on' AT THE VERY END, TO
# ACTIVATE RPi's INTERNAL WI-FI HOTSPOT, as this kills Internet over Wi-Fi!
# 3. Run 'sudo raspi-config' on RPi, to set LOCALISATION OPTIONS
# 4. OPTIONAL: if you have slow/pricey Internet, pre-position KA Lite's
# mandatory 0.9 GB English Pack (en.zip) within /tmp -- you can grab a copy
# from http://pantry.learningequality.org/downloads/ka-lite/0.17/content/contentpacks/en.zip
# 5. WHEN YOU RUN 1-LINE INSTALLER 'curl d.iiab.io/install.txt | sudo bash'
# YOU THEN NEED TO TYPE IN YOUR PASSWORD IF ON UBUNTU/DEBIAN/ETC (for sudo)
# ^^^ ^^^^ ^^^^ ^^ ^^^^ ^^ ^^^^ ^^^^^^^^
# 6. Follow on-screen instructions (TYPE 'sudo iiab' TO RESUME IF EVER NECESS!)
# 7. About 1-2 hours later, it will announce that INTERNET-IN-A-BOX (IIAB)
# SOFTWARE INSTALL IS COMPLETE, prompting you to reboot...TO ADD CONTENT!

set -e # Exit on error (avoids snowballing)
export DEBIAN_FRONTEND=noninteractive # Bypass (most!) interactive questions
# Save script to /usr/sbin/iiab (easy resume/continue mnemonic 'sudo iiab')
mv /usr/sbin/iiab /usr/sbin/iiab.old || true # Overrides 'set -e'
curl https://raw.githubusercontent.com/iiab/iiab-factory/master/iiab > /usr/sbin/iiab
chmod 0744 /usr/sbin/iiab
# Run install script!
/usr/sbin/iiab
An Ethernet cable is HIGHLY RECOMMENDED during installation, as this is more reliable than Wi-Fi (and faster too!) If however you must install over Wi-Fi, remember to run "iiab-hotspot-on" after IIAB installation, TO ACTIVATE YOUR RASPBERRY PI's INTERNAL WIFI HOTSPOT (thereby killing Internet connectivity!)
