You need to install the github version of link2GI. There are some major changes in comparison to the CRAN version.

please send your sessioninfo please check also that GRASS7.x SAGA QGIS and OTB are installed

ahmedshovon commented 6 years ago

Do I need to install OTB as QGIS tool? Under the 'Available QGIS Data Provider Plugins' (Help--> About), OTB is not showing. Is there any way I can download it as a stand-alone software?

gisma commented 6 years ago

Please follow as mentioned in the readme the installation instructions of the RQGIS team

ahmedshovon commented 6 years ago

The OTB provider was removed from QGIS 3.0

gisma commented 6 years ago

I know. It is not a question of OTB in QGIS but OTB on your system. You may install them with QGIS or standalone it should word. Please note I did not make any thests with QGIS based installations of QGIS 3.x. link2GI´ is a wrapper for the standalone binaries and it is also tested forQGIS` version <3.0

Package seems working now. When I tried to produce dsm from given las data I have this error:

dsm1 <- uavRst::pc2dsm(lasDir = "lasdata.las",

  • gisdbase_path = projRootDir,
  • type_smooth = "gauss",
  • otb_gauss_radius = gauss,
  • grid_size = actual_grid_size,
  • GRASSlocation = "dsm",
  • grass_lidar_method = "mean",
  • giLinks = giLinks)[[1]] Error: 'pc2dsm' is not an exported object from 'namespace:uavRst'

I have a CHM generated from lastools and lidR. I got this error.

tPos <- uavRst::treepos(chmR,

:: start crown identification... :: run pre-segmentation... :: filter results... :: find max height position... :: calculate chm statistics Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv, : Cannot open data source
