Re: [spdlib-develop] where is the function of hemisherical projection

Hi Dan, Pete, Thanks a lot for all the helps! I now run the spdtranslate correctly. But may I suggest one thing about the -x option, index method? As multi-spectral lidar emerging, we can classify each point potentially. Even with single-wavelength full-waveform data, we can classify with pulse sh

Re: [spdlib-develop] where is the function of hemisherical projection

Hi Zhan, You need to define a scheme when importing ASCII data using the ‘—schema’ flag. There are some examples in the schemas folder of the SPDLib source. You can modify the xyzi.xml one, changing the delimiter to “ “. Thanks, Dan > On 4 Feb 2015, at 15:41, Zhan Li wrote: > > Sorry for b

Re: [spdlib-develop] where is the function of hemisherical projection

Sorry for bugging again... I got segmentation fault error. My ascii file is formatted as x y z I (they are separated by a space, no header line). Is it because there might be some funky points in my data? Our point cloud data has some noise so far we haven't figured out a good way to remove. If hel

HI Zhan, If you open the SPD file in hdfview then you can save out the quicklook image. Cheers, Pete > On 4 Feb 2015, at 13:05, Zhan Li wrote: > > Oh oh this is embarrassing that I missed my typo error... Hectic day... But > good to to know the indexing should export to SPD. I was wonderi

Re: [spdlib-develop] where is the function of hemisherical projection

Oh oh this is embarrassing that I missed my typo error... Hectic day... But good to to know the indexing should export to SPD. I was wondering if ASCII to ASCII could work... Is there a way to export the quick view image in SPD to a tif or other imag file? If not I think I'll read the quick view f

Re: [spdlib-develop] where is the function of hemisherical projection

Hi Zhan, Going from ascii to ascii won’t do anything in terms of an index. If you want an indexed file it needs to be an SPD file. So you should have --if ACSII --of SPD. Cheers, Pete > On 4 Feb 2015, at 07:30, Daniel Clewley wrote: > > HI Zhan, > > I think the problem is you’re only usin

Re: [spdlib-develop] where is the function of hemisherical projection

HI Zhan, I think the problem is you’re only using single dashes for -if and -of it should be: —if ASCII —of ASCII To get the latest version of SPDLib you can check out the development version: hg clone https://bitbucket.org/petebunting/spdlib Thank

I got error from running spdtranslate in my installed version. Maybe there is a updated version I need to reinstall? Thanks, Zhan. $ spdtranslate --output "HFHD_20140919_C_1064_cube_bsfix_pxc_update_atp2_sdfac2_sievefac10_ptcl_points_ascii_hsproj.txt" --input "HFHD_20140919_C_1064_cube_bsfix_pxc

Re: [spdlib-develop] where is the function of hemisherical projection

Hi Dan, Thanks for the help. I was checking out the wiki page and it still lists spd2spd. But I just checked spdtranslate, there is no option for hemispherical projection. There are "polar", "spherical", and "scan". What is the definition of polar system here? Does it mean hemispherical projection

Re: [spdlib-develop] where is the function of hemisherical projection

Hi Zhan, In the latest version of SPDLib spd2spd has been replaced with spdtranslate, you can use this to project data to a hemispherical system using the same flags. Thanks, Dan > On 2 Feb 2015, at 19:28, Zhan Li wrote: > > Hi I installed spdlib with a "version" label 20130504. I didn't see

[spdlib-develop] where is the function of hemisherical projection

Hi I installed spdlib with a "version" label 20130504. I didn't see the spd2spd command that can project TLS data to a hemispherical projection. Is this version not complete or the projection function is moved to another command? Has anyone had the same issue and known how to get the spd2spd back?
