Releasing modified mosquitoes precisely

Tue, 16 Feb 2021 03:49:51 +0000

At PyCon Indonesia, I spoke about a project we worked on with the World Mosquito Program.

The World Mosquito Program (WMP) modifies mosquitoes with a bacteria – Wolbachia. This reduces their ability to carry deadly viruses. (It makes me perversely happy that we’re infecting mosquitoes now 😉.)

Modifying mosquitoes is an expensive process. With a limited set of “good mosquitoes”, it is critical to find the best release points that will help them replicate rapidly.

But planning the release points took weeks of manual effort. It involved ground personnel going through several iterations.

So our team took high-resolution satellite images, figured out the building density, estimated population density based on that, and generated a release plan. This model is 70% more accurate and reduced the time from 3 weeks to 2 hours.

Chennai on Google Earth in high resolution. Mylapore and other areas near the coast are not yet in hi-res, though.

Google Maps traffic violation

Google Maps gets Edwin Soto out of a traffic violation. He was able to use his laptop and wi-fi connection at the court to show the judge that Cathedral Parkway, where he ran a red light, was a two-way street and not a one-way as the cop indicated.

S Anand 4 Jul 2005 5:00 am: It gets better than SimCity. You can tilt the view of a city and fly by the skyline on Google Earth.

Surprises in satellite maps

Surprises lurk in satellite maps. Like the tsunami hitting Sri Lanka, an erupted volcano, bombing at Baghdad, etc.

Blue marble. NASA’s incredibly detailed pictures of earth. Downloadable.

Kumbh mela from sapce

Kumbha Mela from space. If they can do this for free, I suppose Frederick Forsyth’s and Tom Clancy’s description of satellites catching individual’s faces can’t be far from the truth. They’ve got a pretty good gallery.
