Hi everyone, I was trying out the surface plots using plotly in dash lately and the example code using the mt bruno elevation csv worked fine. However, I was wondering how the csv file was generated, as I would like to do something similar for local peaks within my region.
The dem data you are referring to are not obtained by scannning scanning Mount Bruno. There are publicly available dem data online, like this one: https://gisgeography.com/free-global-dem-data-sources/
I’m not aware of a tool that giving a mountain name it returns the corresponding DEM data.
Thank you for your response. I managed to obtain raster DEM for my areas of interest via the jaxa website. I then tried using gdal2xyz in qgis in an attempt to get an xyz export as that of mt bruno but only got three columns in the export. I have tried looking up other means of obtaining the file as mt bruno but I have not been successful. Do you have any advice of converting the raster DEM to the mt bruno type of format?
To plot a DEM you need an array of shape (m, n), to be passed as the Surface z.
Do you have any information on what your columns represent? I suppose they are x, y, z coordinates. Inspect the x-range and y-range and try to deduce how the z-column converted to an array can be reshaped to get the right z for a Surface.
