GIS file for 4 scenarios #1
Comments
@agrignard, this is a great, clear data request! Thank you! |
First iteration with GIS for the 4 scenarios + Population (still some adjustment that will be discussed later together but the file look pretty promising) e4449b8 |
Ok so after checking the last commit it seems that we are close to close this issue I let this issue open for now just in case there are some slight change to do especially according to #9 |
@agrignard I agree. I will do in the next issues. |
@agrignard can you elaborate your idea about "reducing number of point"? Maybe some quick sketches about it? |
By number of point I mean tha a polygon is made of a list of points. Depending on the definition you can have 100 hundreds points to define only one polygon whereas you might need less. In this case the original form in yellow is made of many points I don't know exactly but something like 30 points I guess and it could be replace by the white shape which is only made of 4 points. This example is volontary drastically different and made by hand so that you get the concept. There are many tools to simplified a geometry by keeping its topology. Of course you don't want to do it by hand I suggest to have allow at this kind of methodology or this one in QGIS https://qgis.org/api/2.2/classQgsTopologyPreservingSimplifier.html |
@agrignard thank you. We will look into it. |
@LAAP: after working with Front_End, I figured out we will have 3 interaction models (plate) presenting 3 urban structures (landuse). So to control the year (2021/2030) (which will control the population), we must use tablet to send that signal. In that case, what will happen if audience select the year 2021 and load physical model as scenario 2? Technically we will have 6 scenarios: {scenario 0: 2021+interaction plate 1, scenario 1: 2030+ interaction plate 1, missing: 2021 + interaction plate 2, scenario 2: 2030 + interaction plate 2, missing: 2021 + interaction plate 3, scenario 3: 2030 + interaction plate 3}.
Please lets me know your thinking. Thank you in advance |
I see we can simplify this GIS file, however we have already printed our 3D model base on this GIS file. It may create a certain differences. |
Dear @Hai-Hoang-88 , I have moved the Question about the 3, 4 or 6 scenarios into a new issue |
For the simplification of the shape ,IT IS NEEDED as CityScope doesn't allow to push so highly definite files and even for any modules it doesn't make sense to have to high level definition . Even if the 3D model is already in process actually (it would have been great to agree on this together before and it might have also simplified the construction of the model) it's ok to simplify the shape that you will display on it if they are not too simplified non one will be able to notice (remember that the definition of your screen is not infinite either so even super precise shape will be simplified by default on the rendering) Do you have a first iteration of a simplified version? |
Dear @Hai-Hoang-88 , @agrignard et al. A- Keeping the 4 scenarios as it is, and making a "Twin" 3D plates for scenarios 0 and 1. The Twin plates can have a label with the name of the scenarios, and even, different level of transparency or color. B- Having only 3 scenarios scenarios, so we remove the scenario number 1, and we have 3 completely different 3D plates for the 3 different scenarios |
This is strongly link to issue #9 so we close it |
We will need to provide for each of the 4 scenario 3 differents shapefile: landuse, building and road
So far a first step has been made in this commit 1526e60 where th Scenario2/LandUSe_Scenario2 has been pushed.
So what we miss now is:
Scenario 0 : District 4 as it really is in 2021
Scenario 1: District 4 as it is but with the 2030 population (Increase of density)
Scenario2: Vision towards 2030. Accepted 2014
Scenario 3: Utopian Vision Autonomous resilient communities. Human scaled cities (SDMC + ARC + CS MIT ML) - 2021.
