importing ASCII Grid file

[AndrewPerth]

hey guys,

I'm looking at some .asc files that appear to be ASCII Grid files. Is it possible to load these into cloud compare?

You can try to load it as a raster, but I don't know if this particular format will be recognized (by GDAL, the third party library that loads rasters). Otherwise you're doomed ;)

Hi Daniel, how would one load it in as a raster? A google search, reviewing previous board posts and just messing around with Cloud compare yielded no results.

[daniel]

Oh, you have to select the 'Raster' filter in the file opening dialog. Then try to load the file (GDAL will try to autodetect the format).

[AndrewPerth]

Ahhh, ok. I had been dragging the files directly into Cloud Compare which bypasses that dialog!

Works perfectly fine now, thank you for your assistance!

Only problem now is having to hit Yes over and over again when it's asking whether to remove NaN points and agreeing to the point translation due to the large amount of individual files i'm working with.

Yes, when you drag the file over the window, CC detects the format based only on its extension. And ASC is a standard cloud format (well, it's also a raster format, but CloudCompare is primarily for clouds ;).

For the Global Shift, you should be able to load all the files at once (with CTRL or SHIFT + select) and then click on the 'Yes to all' or something equivalent.

For the NaN points... we'll have to work on that ;)
