영국의 비오는 날에 대한 데이터가 포함 된 NetCDF 파일이 있습니다. GeoTIFF로 변환하고 싶지만 GDAL을 올바르게 지리 참조 할 수는 없습니다. 아래 gdalinfo의 덤프를 참조하십시오.
"raindays_tmean_abs"변수를 보여주는 단일 밴드 TIFF가 필요합니다. "lat"및 "lon"변수는 영국에 데이터를 저장하기 위해 합리적인 최소 / 최대 값을 갖는 것으로 보이지만 gdal_translate로 변환하면 아프리카 서해안에서 끝납니다.
첫 번째 차원이 "시간 또는 수직"차원이 아니라는 경고가 표시됩니다. gdal은 데이터가 특정 순서로 나타날 것으로 예상하므로 이것이 문제 일지 모르지만 수정 방법을 모르겠습니다.
이 데이터를 어떻게 변환 / 재 투영합니까?

... 안타깝게도 아직 50 평판이 없으므로 의견을 남기지 않고 '응답'합니다. Windows cmd-line을 사용하는 gdal 솔루션에 매우 관심이 있습니다! R을 사용하여 gdal_translate 명령을 cmd 라인에 넘겨줍니다. 내가 지금까지 시도한 것은 다음과 같습니다.```data_source <- 'D : /user1/01_data/input.nc'data_output <- 'D : /user1/01_data/output.tif'system (command = paste ( 'gdal_translate- GTiff -sds -a_srs epsg : 4326 ', data_source, data_output))```이 작동하지만 crs 정보를 잃어 버리고 있습니다 ! crs 정보를 유지하는 방법을 아는 사람이 있습니까?
