For Australia, elevation data can be downloaded from here: https://elevation.fsdf.org.au/. However the data comes as ASC files without hdf files, so I assume that the files are not ESRI ascii grid files. Prj files are provided. If you zoom into Canberra, DTM data of 1 m ground resolution is available. I would love to be able to import this data into manifold 9 but it comes in as table data with one table for each file. What I am after is a raster that covers my area of interest. If I could get the data in as a raster, I would be able to try out that nifty curvature filter to try and find old tracks through the hills. How hard can it be!

I was able to import one of these without any issues. I clicked File/Import and navigated to the .ASC file and opened it. It imported quickly and after setting the Style displayed. I didn't try and select from the drop-down list of file formats anything. I just chose the file and it took off.

(I tried to download and import an example file to see what is going on and with the site above hosting multiple data sets I did not know which data set to pick. I picked a couple and none of them came as ASC. If you continue having issues with a particular file, maybe post it on the forum - I guess you can select a smaller region and post the result returned for that smaller region to make the file size fit the forum restrictions.)
