In this clinic I will give an overview of lsdtopotools so that, by the end of the session, you will be able to run and visualise topographic analyses using lsdtopotools and lsdviztools. I will show how to start an lsdtopotools session in google colab in under 4 minutes, and will also give a brief overview for more advanced users of how to use our docker container if you want access to local files. I will then use jupyter notebooks to give example analyses including simple data fetching and hillshading, basin selection, simple topographic metrics and channel extraction. Depending on the audience I will show examples of a) channel steepness analysis for applications in tectonic geomorphology b) calculation of inferred erosion rates based on detrital CRN concentrations c) terrace and valley extraction d) channel-hillslope coupling. In addition I will show our simple visualisation scripts that allow you to generate publication-ready images. All you need prior to the session is a google account that allows you to access colab, and an opentopography account so you can obtain an API key. The latter is not required but will make the session more fun as you can use data from anywhere rather than example datasets. If you are not an advanced user please do not read the next sentence, as you don’t need it and it is nerdy compu-jargon that will put you off the session. If you are an advanced user and wish to try the docker container you should install the docker client for your operating system and use the command “docker pull lsdtopotools/lsdtt_pytools_docker” when you have access to a fast internet connection.
