"Invisioning a Perfect Pellucidar Map" Topic

Take a map somewhat like this one…

Flip it east-to-west to get the mirror image… remember, if you are on the inner surface looking down you'd be looking at a reverse view of the land/sea masses.

Find a really cools software program that allows you to reverse the ocean depths and mountain heights (I wish!!!)… what was high is now low and vise-versa.

Flood the low areas and faster than you can say "Dian the Beautiful"… you have Pellucidar.

I might be tempted to not flood the coastal plains to make the continent/ocean outlines less familiar to the players/gamers.

It might look a lot like this one…

I just wish there were more detail to ti.

You could take a 100m DEM and calc the cellsize by -1 which would reverse mts and valleys. What elevation would you want the water to fill up to (ex: any +/- to the 0' elevation).

I would use the Spatial Analyst extenstion to ArcMap to do this. This is a GIS/cartographic software I use at work. I will see if I can try something as this could be cool.

er…. Redroom… ah….

What language was that?

;-)

Does this help a bit?

yeah redroom, I have a feeling there was something of interest in your post…but I don't understand it.

Lets see if my translation helps:

DEM – Digital elevation model or how to store a map on a computer

ArcMap is a program for showing map data and letting you manipulate it and draw maps. Spatial Analyst is an add-on to the core programs ( link )
The -1 is a function to flip mountains to be valleys and valleys to be mountains.

0' elevation is where you could draw sea level by default – this can be raised or lowered as needed.

Before you ask – nope I am not a cartographer but am married to an amateur archaeologist and father to a practising one – both of whom want a GIS for Christmas (no hope – the cost of these things is more than I spend on wargaming in a life time).

That first map Warrenss2 linked to looked good but Australia and India were a bit of a give away. Maybe a little artistic licence should be employed to brake up the more obvious coast lines.

That method of producing a Pellucider map would of course made the use of burrowing machines extremely hazardous. Whatever land mass you start from you'd always brake through onto the ocean floor!

I'm trying to remember… did Burroughs ever give the idea in the books that the land masses were the reverse of the ones on the 'outside'?
If not I'd be inclined against the 'reversal' idea.

Sorry, GIS techno-babble. Andrew has it correct; DEM is a Digital Elevation Model which is basically a collection of X,Y,Z points where Z is the elevation. I am Geology/Computer Science developer-type more than a cartographer.

Andrew – globalmapper.com is a really nice, relatively cheap product (~ $300). You might also get them to look at ArcExplorer (free) link

Venusboy3, I not sure what aspect of land masses being reversed you're meaning so I'll cover both.

In the Pellucidar series Burroughs wrote that the Earth's crust was only, if I remember correctly, 700 or 1000 miles thick. Since it's so "thin" what are mountains on the outer crust would be trenches in the inner world's oceans and what's trenches in the outer world's oceans would be mountain ranges in the inner world.

As for reversing the east/west orientation of the land masses… Hold up a regular map to the light (the outer world)… imagine digging thru that sheet of paper until you reach the other side (the inner world)… turn the map around and look at the back side of the paper while holding it up to the light… This will give you the proper orientation of how the land masses would be reversed.

Commodore Wells 2, the hazard of burrowing into the bottom of a Pellucidarian sea is something all explorers of the Inner World must face. Perhaps if we launched our Ironmole from a ship at sea (sinking straight down… nose first) would improve our chances? Or we might take advantage of the polar opening?

;-)

Redroom, I'm going to check out that free software!

Thanks for the link!

"In the Pellucidar series Burroughs wrote that the Earth's crust was only, if I remember correctly, 700 or 1000 miles thick."

Even thinner, actually:

I really can't see how this is the "negative" of the surface land forms:

CC…

Me neither.

I guess there must be more coastal leeway than we thought.

The Earth's crust is only 500 miles thick? I'd almost be too afraid to stomp my foot for fear of punching through it! LOL!

Science aside, Pellucidar has always been something I've wanted to game, if someone comes up with suitable Sagoths, that is.

Warren,

Did you do anything further with your map quest?

If I could find some software that would allow me to not only flip the map in an east/west orientation, but reverse the elevations and flood the new low lands…

Burroughs maps could not have been accurate (I realize it's only sci-fi/fantasy/pulp/adventure)… there is no place that even remotely has a contour interval setup like this…

Even if you flood the continental plain or recede the water off the continental shelf.

Plus they started in Connecticut, went straight down to enter Pellucidar. One the return trip, back to the outer crust, but the Iron Mole tilted to an angle when it drilled into the earth… Had to be on H#LL of an angle for Innes and the Mahar to come up in the Sahara.

Like I said, it's all just fiction. But I'd like to see and get a better idea of what Pellucidar would look like as if it really existed.
