[gdal-dev] Convert WGS84 geodetic coordinate to local ENU(local Cartesian coordinates coordinate system)

Hello. Is there any method in GDAL that can convert WGS84 geodetic coordinate to local ENU(local tangent plane)？ First: GDAL can transform point coordinate from WGS84 geodetic coordinate system to WGS84 XYZ (or ECEF ). Second: but WGS84 XYZ (or ECEF ) to local ENU can not be transformed. I can fix

[gdal-dev] Coordinate transform from coordinate reference systems with different datum error in GDAL3.0.0

Hello, I would like to ask: When I use GDAL 2.3.3 with proj4_4.9.3, I can convert the coordinate from EPSG:4326 to EPSG:4326+5773(egm96_15.gtx) correctly with elevation value. But when I use GDAL 3.0.0 with proj4_6.1.0, the elevation value of coordinate unchange (Proj.db and egm file are found). Th
