Advice on how to display plumes of smoke

    I have been asked to generate a map for an emergency planning exercise. There is no data as such but essentially I need to generate a file to be printed out which shows smoke/fumes over a small area from a certain point. It's outside of what I normally do and I wondered if anyone had any visual examples and/or suggestions about how best to achieve it and make it look visually correct (or just appealing). I could just display a polygon over the area and shade it but just wondered if there is a better solution.

    Many thanks
    Martin

    Hi Martin,

    Interesting!  I guess the main issue would be wind-direction, but if this isn't being considered in this exercise then your suggestion of using a polygon to represent the 'cloud' would be best.  I would make it irregular, rather then just a circle, and make it grey with transparency, so the base mapping can be seen.  Here's a couple of examples I've just knocked up using the eclipse tool and then merging objects together.


    I guess you could add a symbol to show the point of escape, if that was relevant.

    Interesting to see what others come up with.

    You can also download any of these fancy plumes of smoke images and insert them as images on the layout on top of your map.

    It might however be a bit harder to locate these images correctly in the map and maintain that location if you zoom or pan the map.

    These images were found here: https://ya-webdesign.com/explore/smoke-plume-png/
    But you might be able to find other similar images on other sites. The site above seems to provide free images but I haven't studied the licenses closely.

    Plume modelling Martin? Plume modelling...

    There is some free software from the US called Aloha​ (been around donkeys years and used to pay for it).
    It is mostly used for chemical spills/emergencies and has a huge database behind it of every concoction that
    would represent a problem if accidently spilled or released. It then takes in parameters of volume and wind speed
    and direction to produce a Plume. Export to KML and pop it into MapInfo...
    https://www.epa.gov/cameo/aloha-software

    Could be handy?

    ​Thanks all of you for the answers. I simply now have to decide how much time I have to spend on the project!. The plume images look good and they are copyright free (useful site!) and the Aloha software also looks a useful tool with some good supporting documentation.

    Hi Martin

    You may want to look at the CHEMET data provided by the Met Office.The data they supply usually consists of a dispersion point and a several polygons generally detailing high and low risk areas and an associated time period the data is valid for. Have a look at this for an example CHEMET leaflet
