    49 A new module, G74:r.geomorphon, to calculate geomorphons (terrain forms) and associated geometry using machine vision approach has been integrated (moved from Add-ons) into the core functionalities of GRASS GIS. A very nice addition to G74:r.out.gdal is the possibility to create overviews which enhances the compatibility with other GIS software packages.

    51  * fixed longitude wrapping for lat/lon locations
    52  * support import of raster maps exceeding 90N or 90S or with an EW extent larger than 360 degrees
    53  * lat/lon: automatically fix floating point precision errors in the grid geometry of imported raster maps created with GIS software that uses limited floating point precision (common problem).
     51G7:r.in.gdal and G7:r.external provide support for import of raster maps exceeding 90N or 90S or with an EW extent larger than 360 degrees. Moreover, for imported lat-lon maps created with GIS software that uses limited floating point precision (common problem), an automatic fix of floating point precision errors in the grid geometry was implemented.

    55  * G74:r.regression.multi: added RMSE and MAE estimation
    56  * G74:r.what: added new -v flag to return also vector category
     53G74:r.regression.multi provides RMSE and MAE estimations for the regression model. A new -v flag was added to G74:r.what to return vector category number.

    131126In the past year of development, there were several changes in different GRASS GIS libraries. The most relavant changes are described below:
    132  * In the rasterlib there is now NULL file compression by default.
     127 * In the rasterlib there is now NULL file compression by default and longitude wrapping has been fixed for lat/lon locations
    133128 * The temporal framework has now support for spatial topological operators to the temporal algebra, several tests were added as well as a new function to convert granularity to a smaller granularity, and raster region specific parallel processing has been enabled by means of the MultiModule new class in PyGRASS.
    134129 * projlib now provides improved integration of GDAL and streamlining of spatial reference system handling, as well as new functions (GPJ_grass_to_wkt2 and GPJ_grass_to_osr2)
