Users may wish to download larger sections of data spanning multiple tiles, flight paths, or data types. Such bulk downloading can be done using freely available tools such as Wget. For example, to download all the point cloud data structured by tiles, users can execute the following wget command in a terminal window.
wget -nc https://serv.cusp.nyu.edu/projects/ALSDublin15/json/all_bitstreams.json && grep '\<.*pc.*T.*\>' all_bitstreams.json | tr -d ',' | xargs wget -nd --no-check-certificate
The wildcard \<.*pc.*T.*\> in the command defines the data subset to be downloaded. Namely, pc restricts the results to point cloud data only, and T restrict the results to data structured by tiles.
Below are some other wildcards for common download patterns:
\<.*pc.*F.*\> |
Point cloud structured by flight paths |
\<.*fwf_las.*T.*\> |
Full waveform data in LAS format structured by tiles |
\<.*fwf_las.*F.*\> |
Full waveform data in LAS format structured by flight paths |
\<.*fwf_plswvs.*T.*\> |
Full waveform data in PulseWaves format structured by tiles |
\<.*fwf_plswvs.*F.*\> |
Full waveform data in PulseWaves format structured by flight paths |
\<.*oblique.*\> |
Oblique images |
\<.*rgb.*\> |
Geo-referenced RGB images |
\<.*cir.*\> |
Geo-referenced CIR images |
\<.*orthophoto.*\> |
Ortho-photos |
\<.*MOV.*\> |
Video data |
\<.*misc.*\> |
Miscellaneous data |
\<.*T_316000_234000.*\> |
All data of tile T_316000_234000 |
\<.*F_150326_123922.*\> |
All data of flight path F_150326_123922 |
\<.*manifest.*\> |
SHA-256 checksums |
