TGC-Designer-Tools not reading lidar files #75

Closed north00001 closed 3 years ago

north00001 commented 3 years ago

Anyway I can send in the actual *.laz files for you to test with?

north00001 commented 3 years ago

Actual error is :

Processing: USGS_LPC_CA_Central_Valley_2017_10SFG750850_LAS_2019.laz Using metadata: USGS_LPC_CA_Central_Valley_2017_10SFG750850_LAS_2019_meta.xml Could not determine lidar projection, please report an issue and send this lidar and metadata Alternatively, look for something called EPSG Value in Metadata and provide EPSG.

Trying to send you the files per the text generated in your application.

" Could not determine lidar projection, please report an issue and send this lidar and metadata"

But the zipped file size is to big, 28MB, for sending through this open ticket application.

If it can not find projection its not in the meta data. If you are able download the *.LAS file. If thats not an option find another reading. Different year or so

Unzipped the .laz file to extract the .las file using LAStools's laszip.

This file was the result, USGS_LPC_CA_Central_Valley_2017_10SFG750850_LAS_2019.las. Ran it through your application and got the following : Processing: USGS_LPC_CA_Central_Valley_2017_10SFG750850_LAS_2019.las Using metadata: USGS_LPC_CA_Central_Valley_2017_10SFG750850_LAS_2019_meta.xml Could not determine lidar projection, please report an issue and send this lidar and metadata Alternatively, look for something called EPSG Value in Metadata and provide EPSG.

I've also tried a number of EPSG files for the central California area (Zone 3) with no success. Zone 3 includes the area where Escalon Golf is located.

EPSG:2227: NAD83 / California zone 3 (ftUS) EPSG:2768: NAD83(HARN) / California zone 3 EPSG:2872: NAD83(HARN) / California zone 3 (ftUS) EPSG:3493: NAD83(NSRS2007) / California zone 3 EPSG:3494: NAD83(NSRS2007) / California zone 3 (ftUS)

Any Thoughts?

Thanks for looking into this.

I did try Epsg is 32630 but that is not the area where the golf course is located,

EpSG 32630

This is the one I need to work , Epsg 2227 EpSG 2227

Do I need to open a new ticket or can this one be reopened?

north00001 commented 3 years ago

Let me say that I appreciate your work on this Designer Tool, I was and applications designer for 15 years though retired now for 7. I am contemplating downloading the app from GitHub and seeing if I can resolve this myself. I did a little python coding but my core was Java, PL/SQL. HAve a good day

north00001 commented 3 years ago

Gentlemen, thanks for your help. I eventually found the site http://epsg.io/?q=california&page=9

Here I tried many EsPG files till I found EsPG 6339, which worked :)

Your application correctly displayed both images with the left one having the highlighted golf holes.

Success!

Closing ticket, lol
