Second post but first large map using the techniques of Grassrootsmapping.org for LA Bucket Brigade – thanks guys for putting this wonderful DIY technology together. So! In the late morning 22nd of July 2010, Hunter Daniel and myself went to map out of Port Sulphur, on these funky boats :

With 2 boats we took this route (see google map) :

I traced this route with my mobile phone Google Nexus One and the fantabulous Open GPS tracker for Android – 4 stars rating!
This is what we could see from the boat, kinda boring :

Soon after I launched a balloon and Hunter a kite out there, kinda exciting :

we captured nice pictures, here 6 details :

These 6 pictures were made using 270 stills… that was a 12 hours work on photoshop sincehugin (an open-source photo mosaic software) didnt do the trick – yet :/ Still working on it to automate the process and spend more time sipping mango juice 
In addition to what we had a bad GPS trace – my bad, I mean, it is good but I did’nt know where we started taking pictures on that route… Also the GPS time-stamp and the camera time-stamp did not match… So, here is the trick I found:

Ok, so now we have this huge empty map :

That’s another 6 hours work adjusting 700 pics layer by layer on photoshop ; hey, 270 images in 12 hours VS 700 images in 6 hours => see, it is much faster with a support map! We got that :

Don’t forget to put a scale and cardinal orientation + legal mentions.
So, under your eyes that’s a 17000 x 17000 pixel map, made of 970 pictures taken at 1000ft altitude, depicting about 5 linear km of damaged coastline. Combining the 6 details views and the general map we could observe that the south side was much more exposed to the spill (more dark brown brrrrr). Using this map we could also establish that on the exposed side, even the inland waterways are strongly affected by the spill : we can use these maps to quantify the surface affected by the oil spill, and the mass of crude attached to the surface coastline. Now even cooler, you can see these maps on google earth, download the KMZ file here (dont worry it is a tiny file – all the content is online). FLY !

Apart from mapping this catastrophe – which is very useful for scientific study and for lawsuits against BP- why am I personally learning aerial photography? Well, because I am currently designing an oil collecting robot called “protei“.

Protei is a sailing semi-autonomous robot with a long oil absorbing tail. Surface oil drifts downwind, so Protei sails upwind, taking and taking, intercepting oil sheens. Imagine many many of these cheap machines out there in the ocean collecting oil 

After some research …

I built a steampunk test machine that is pretty promising with a flexible hull front-steering :

We are also testing at sea the behavior of a long tail, and same, going pretty well …

See these little balloons on the surface of the water? And this is when aerial photography comes handy : to evaluate the efficiency and behavior of Protei, seeing everything from above helps a lot, I can see the trajectory, the movement of the tail, the interaction with oil.  Also having a highly visible “flying flag” in the sky is amazing to optimize safety and long range communication (flying antenna)… Exciting no? And the challenge is here, millions of liters of crude oil gushing in the Gulf of Mexico, in the Niger Delta, in Latin America, the middle east, in Asia… Protei_Oil_Spill has a busy future!

Of course, just like grassroots mapping, Protei is developed open-source and collaboratively, so I hope that sometimes soon, Protei will come back to land with a lot of amazing pictures for LA Bucket Brigade and its amazing oil  spill map, GrassrootMapping,Cartagen and Open_Sailing! I received most electronic parts for the next prototype of Protei_Oil_Spill this morning (YAY!), I am building in New Orleans, so if you are around, or if you want to help the project remotely, do get in touch – cesar@protei.org – thanks!

Also I must disagree on the discourse that says Industrial revolution will make us free. This is what we have been attempting since 300 years, the same old ideal future that we never reach, a future for a free "updated new" class (a rich minority of "visionaries") that the rest of humanity must labour and pay for it... Our society is industrial, I am not sure getting rid of 90% of human labour with new supertechnological means is the good underlying priority in the agenda...

In other words, the Jaques Fresco "Venus Project" is an interesting and inspiring Utopian project. Someone has to dream, and show a bundle of possibilities to the majority, and the rest of us, as actor-consumers, can buy into it, more or less. Jacques Fresco is doing his job being the figure of the grand visionary architect for a glorious future, I respect that ; but I think to deeply impact the world, every single human needs to have the freedom, capacity and desire to the the architect of his/her own life. And that might not be possible in a world where resources are limited.

So it goes back to the beginning of the Venus project : "a Resource Based Economy". On this everyone can agree, we need to start by considering the resource before making grand plans. The architect should publicly employ his creative mind to fabricate this fabulous tool that will give an entire new perception of our actual system, a tool with which a new -probably much less fancy than described- future can be built.

Also, you cannot be ethically at both ends of the chains : you cant be judge and jury, and if you are : don't expect any credibility.
It is scary for other to have one grand vision that incorporates all the aspects of a NEW life, it is too intimidating and normative.

To conclude : to work out this "not-new" resource limited word, let's do it in the right order : first, let's set up the "sensors" to measure this limited and changing world.
Before we invent super great grand designs and strategies, let's simply get to know what is happening, and make that knowledge available to everyone.
- There is an open-source project that enables people to do that today : http://pachube.com
- There is a global observatory system : http://earthwatch.unep.net/data/g3os.php
