  • There is research that shows that white coloured roofing causes increased heating elsewhere, so it’s not a fix-all solution.

    I live in Australia and during summer use a lawn sprinkler on the roof. Using a tap timer, it runs for 10 to 30 seconds every 10 minutes.

    Just enough to wet the roof, so that the water evaporates and cools it down.

    Other things you can do is growing creeper vines over a wall where the sun hits in the afternoon to keep direct sunlight off the wall.

    If you have sash windows, you can open it at the top and bottom, creating a thermal airflow that will cool the house.

    Adding sunshades and building housing with awnings makes a massive difference.

    Lots of research associated with passive solar temperature regulation.


  • Anything that has a physical location or relationship can be mapped.

    If you can find existing datasets you can add those to the map without needing to manually collect the data.

    You can also consider things like floodplains, historical flooding records, traffic flows and anything else will a geographical bent.

    This will never be finished because things are always in flux.

    One thing that you should consider is what maintenance looks like. Keep track of where datasets came from and when you retrieved them. Some countries, regions and municipalities maintain public data that you might be able to use. Make sure you comply with any licences attached to the data.

    You can also use things like the local cadastre which tracks land and building boundaries and ownership.











  • I’ve seen similar weird stuff previously which turned out to be a database compatibility issue of some sort. I haven’t investigated, but is that instance running the current version of Lemmy?

    Also, at the time it was not clear if the issue was related to the instance where the post was, or the instance where my account was, so check the version on your own instance too.
