Re: [maptiler] Using your map to illustrate the evolutionary tree

[Andre Mano]

Whoaaaaaaaa amazing!! 

Lovely work! Unfortunatelly I don't know how to help you, but I had to make a remark - amazing depiction!

BTW is this work free for use to educational purposes?

Best regards,

André Mano

Hey Petr,

Great software. I'm looking into a way to illustrate the evolutionary tree and I've been experimenting with your mapping software to  generate a map for the Hillis Plot to make it easier to navigate. I've got a couple of questions if you could spare a moment I'd be very greatful.

Here's the link

http://www.gavindonohue.com/200cm/openlayers.html

What's crazy is this plot only depicts 0.18% of all known living species! So the species in the centre represent our earliest common ancestors. You can see how these branched into 4 main groups (Animals, plants, fungi, protists). What you can't see are the names of each ancestor (only living species are depicted on this plot) because there would be far too much text to fit all these ancestors names. You also can't see pictures of any of the species which is a shame. BUT it is the best we've got at the moment and the creator David Hillis deserves much credit.

Question 1: It would be so awesome if there was some way of having different 'time levels'. It would require that instead of zooming into the image the user is zooming into different images. The 0 time level would be an image of our common ancestor. Time Level 1 would show the split into the 4 main groups and their names. Time Level 2,3,4,5.....etc 

I know this is very different to how your software works and perhaps I have not explained the concept very well but I would be very interested in anything you have to say on my project. 

Question 2: The link doesn't seem to work for mobile? Is there any way around this?

Hi Gavin,

While not to take attention away from the great software that MapTiler is, it seems that what you want to do is perfectly suited to CartoDB/TileMill... check them out...

Best,

Joe

Thank you Joey, I'll check it out.

And André, the image itself is not mine. I've merely made a map out of it. But the person who did make it has made it free to use for educational purposes. You can read more about it here

The enormity of life on earth is mind boggling. I'm just hoping to make it easier to visualize. 

Thanks again.

Hi Gavin,

The evolutionary tree looks truly great.

To answer your questions:

1) Prepare separate 4 images for the 4 different zoom levels (different details) in Photoshop or elsewhere. All these images should have the same resolution (width and height in pixels). You render these separately with MapTiler or other raster tiling software.

Once rendered, the main directory contains numerical subdirectories representing individual zoom levels. For images with the same size (as you have) you can move the zoomlevel directories into one resulting directory with the viewer. This way you can display your image no#1 on the zoomed out state, when you zoom slightly in then no#2, later no#3 and for most detailed no#4. It means from your image#4 with most details you will copy only the zoom level subdirectory with the biggest number.

2) Mobile and pinch zooming and dragging is fully supported if you upgrade the viewer to the latest OpenLayers stable 2.12 library. It should mean only changing the link to JavaScript library and maybe adding Navigation control with touch support, check:

http://www.openlayers.org/dev/examples/mobile-navigation.html

If you want, you can also switch to other JavaScript viewers, such as http://openseadragon.github.io/.

Then you would need to render the tiles with something like DeepZoom composer (or open-source alternatives): http://www.microsoft.com/en-us/download/details.aspx?id=24819

Best regards,

Petr
