Description

The idea is to have a single map available where users can add/remove layers, which are based on all shapefiles that are available for that particular city. This is the template that Guus made a while age on which to base this work.

Yeah, master map! Is this only for the "content" of the city, e.g. water treatment plant, bus stations, or will this also be for various types of admin. boundaries (districts, neighbourhoods) that can be toggled? If the later, could/would it also go beyond the city and higher to regional, national or NUTS2, 3 etc?


Both infrastructure and boundaries will work. We can look into having higher item levels as well but there must be a logical explanation for including them. We can for instance show the boundary of the NUTS2 level that the selected city is part of, but not any of the other ones. Is that what you have in mind?


Okay so this is now taken to the next level:



  • The map loads all shapefiles that have been processed for this city

  • If official boundaries are established, they will be shown by default in the beginning

  • There is a new way to register official city boundaries (go to PROCESSING > CITY BOUNDARIES)


Example maps: Brussels or Melbourne


Some stuff to do in this version:



  • The official city boundaries are now duplicated (it's both active in the beginning and there is already a layer that can also be activated). Ideally we simply activate THAT layer in the beginning.

  • When the shapefiles contain points instead of polygons, they are not yet the right colors

  • Some of the layers contain a shapefile that has elements OUTSIDE of the city (e.g. all power plants in the province). Sometimes you want to see them, sometimes not. I suggest we have a checkbox somewhere that says LIMIT CONTENT TO WITHIN BOUNDARIES, which cuts off the shapefiles if it's ticked.

  • When in fullscreen mode, would be nice if scroll can be used for zooming in/out

  • Save as image option would be nice

  • We've got to embed all the copyright info on this page, given the NUTS licensing ridiculousness


Here a screenshot of Melbourne


Yes, that's what I had in mind. (It would be NUTS3, which is lower.) The logical explanation and also one that perhaps justifies using other higher levels (up the country level in CityLoops) is putting the city into context and better understanding the downscaling of data.


But, in any case, so cool to see how you have progressed with implementing this and future items that you have thought of! I'm really excited to see the master maps being filled with all kinds of data points as the data is processed 🤓😎


OK coolio, yeah that sounds doable then. When the time comes feel free to make a task for this and I'll then look into it. It works best if all the relevant shapefiles are already processed and available so we can work with the actual info. And I'm also looking forward to the maps filling up!
