Purpose

from #7

this algorithm seeking process has to do with policies related to land take in France. I cannot share too many details because this is an ongoing paper : I am a PHD student in France. We will make sure to credit you if we get the chance to publish an article related to this issue later this year and I'll send you the work. Regardless of what algorithm we end up choosing, the speed at which this processes groups is far better than what we've had so far using Python.

Thanks.

I do not know what 'land take' means.

Land take is the conversion of natural land to sealed soil as a result of urbanization. An european policy aims to halt land take by reducing it by 50% by 2030. This data is a series of surplus/deficits measured in hectares based on localities needs for the next decade. Surplus means the locality has excedentary hectares compared to the 50%, deficits means they have less. Localities can share hectares, and the algorithm does it.

Land take is ...

Thanks. That makes a lot of sense.

Neat project.

The purpose is to reduce the amount of natural land taken by urbanization by 50%.

Sounds like a great idea!

I wonder what the 50% means. Say a locality has a de value of 0. This means, AFAIK, that its planned land take from now till 2030 is 50% of something. What is the something?

Makes me think of the Joni Mitchell song 'Big Yellow Taxi'

They paved paradise, put up a parking lot With a pink hotel, a boutique, and a swingin' hot spot Don't it always seem to go That you don't know what you've got 'til it's gone They paved paradise, put up a parking lot (Ooh, bop-bop-bop-bop, ooh, bop-bop-bop-bop) They took all the trees put 'em in a tree museum And they charged the people a dollar an' a half just to see 'em Don't it always seem to go That you don't know what you've got 'til it's gone They paved paradise, put up a parking lot (Ooh, bop-bop-bop-bop, ooh, bop-bop-bop-bop) Hey farmer, farmer put away that DDT now Give me spots on my apples, but leave me the birds and the bees Please Don't it always seem to go That you don't know what you've got 'til it's gone They paved paradise, put up a parking lot (Ooh, bop-bop-bop-bop, ooh, bop-bop-bop-bop) Late last night I heard the screen door slam And a big yellow taxi took away my old man Don't it always seem to go That you don't know what you've got 'til it's gone They paved paradise, put up a parking lot (ooh, bop-bop-bop-bop) I said don't it always seem to go That you don't know what you've got 'til it's gone They paved paradise, put up a parking lot (ooh, bop-bop-bop-bop) They paved paradise, put up a parking lot (ooh, bop-bop-bop-bop) They paved paradise Put up a parking lot

Using cadastral files, the government is able to tell how much land a municipality has consumed over the previous decade. Using a simulation, we calculate how much a municipality actually needs. "De" is the result of this operation.

This song is indeed quite relevant. You can imagine this law does not make everyone happy ! But for now, it stands.

I do not understand how that works, but I don't need all the details. Enough that I know what this is all about in general terms. Thanks.
