i am trying to create tiles/Layers like this demo website.
http://www.clflightplanner.de/demos/dterra/
but I am new to this googlemaps. Are these tiles or layers?
Any book suggestion or tutorial link to kick off.
these are polygons drawn by google.maps.Polygon which is passed an array of latitude and longitude coordinates

I have a Flutter project using flutter_map and tiles from Mapbox. I also have a very large list of coordinates to create polylines on the map. The coordinates are worldwide geographical boundaries. It's working fine but when displaying the polylines the map gets a bit unresponsive due to the amount of polyline data.
How would I be able to create a custom map with the coordinates/polyline data already embedded in the map to avoid having to draw polylines separately?
Thanks
You could use Mapbox Studio to create a map style with sources and layers referencing these coordinates/polyline data. This tutorial on creating a custom style is a great place to get started.
I need a Google Map with marked up areas with different colors.
GADM data
The first article I came across was this one:
https://ourcodeworld.com/articles/read/830/how-to-highlight-an-area-city-state-or-country-in-google-maps-with-javascript
It links to this service for getting coordinates:
https://gadm.org/download_country_v3.html
The problem is that there are too many points so it would end up with 3MB for an embedded map.
Google Maps draw
Then I tried Google Maps service to draw a shape. While it works, I could not find any export function to get the longitude and latitude.

Question
How can I draw an area on a map and then get longitude and latitude for the points? On Google Maps, a tool or something else does not matter.
I solved my problem very differently. I simply used an svg file of just the country and highlighted areas there.
I used this site:

I would like to use a layer on top of a google map and map the streets on this layer.
Specifically - I have autocad design and would like to implement it somehow into a map, using tiles (maybe MBTiles) and provide info on the design.
I'm familiar with google maps but not on how I can add this layer and information. I don't want to create polygons and polylines in code - I want to use to vector design, place it on the map and add data like street names and such.
How would I approach this?
I'm thinking you'll need to use AutoCAD Map 3D or AutoCAD Civil 3D to extract the layer as a shape file which you can then use with Google Maps.
I'm not sure where to start looking in the documentation, but I'm trying to load map images of cities with their boundaries outlined.
Like this...
Any help getting started would be greatly appreciated, I'm pretty new to the maps api.
Thanks
There is currently no way to request a map with boundaries automatically rendered on it. Your best bet is to pull the polygon information from another system and render using an encoded polyline if you're using the Static Map API or regular overlays in the JavaScript API.
Google Static Map API
Here it is

Ability to draw boundaries on Google Maps
I'm looking looking for a tool that will allow me to make a map exactly like this:
http://datasearch.uts.edu.au/about/mapsdirections/map.cfm
Basically I need to put shapes around buildings in the satellite view and then slap a marker and information window on them so that I can specify the building name and contents.
So the main issue is that I need the ability to draw shapes directly onto the maps as I don't fancy taking down the lat lng of each corner of the polygon.
Ideally what I'd like to do is have an online application that exports those points to KML, and then I would display google maps on my site and import that kml to display it.
Other suggestions welcome!

Found a polygon creator
http://www.the-di-lab.com/polygon/
It's simple to use and allows you to copy and paste straight into your code. Would be nice if it had a button that said sent to kml though..
