gdal

问题 I have .nc file sizing around 300MB with a couple of datasets ( TEMP , DEWPOINT ) forecast data. I need to convert ( TEMP ) dataset to multiple GEOTIFF (one .tif for each time slice). Here is how the .nc file looks like. Looked into this answer but it seems to be for the whole dataset. I tried GDAL but not sure how to make it work for each time slice. Any thoughts? netcdf4 -python? 回答1: gdal has a gdal_translate option that will allow you to do this to translate the file from .nc to .tiff .

问题 Is it possible to set the data type (Byte, Float32) when using gdal.Rasterize in gdal 2.1? Currently, I use gdal.Translate to convert to Byte, but this is inefficient. tif = my/target.tif shp = my/source.shp tiftemp = my/temp/solution.tif rasterizeOptions = gdal.RasterizeOptions(xRes=20, yRes=20, allTouched=True etc.) gdal.Rasterize(tiftemp, shp, options=rasterizeOptions) #translate to Byte data type (not supported by Rasterize?) gdal.Translate(tif, tiftemp, outputType=gdal.GDT_Byte,

问题 I am trying to install GDAL in virtual environment based on the various solutions out there. However the download itself already fails: $ pip install --no-install GDAL Here is the pip.log ------------------------------------------------------------ /Users/test/venv/bin/pip run on Sun Jun 2 15:35:15 2013 Downloading/unpacking GDAL Running setup.py egg_info for package GDAL running egg_info writing pip-egg-info/GDAL.egg-info/PKG-INFO writing top-level names to pip-egg-info/GDAL.egg-info/top

问题 System info: Ubuntu 16.04 64 bit I'm trying to install rgdal_1.2-16.tar.gz for a research project.

问题 I can't install the package "sf" on R. Seems there is an issue with gdal. No idea how to resolve it. > install.packages("sf") There is a binary version available but the source version is later: binary source needs_compilation sf 0.4-3 0.5-1 TRUE Do you want to install from sources the package which needs compilation? y/n: y installing the source package ‘sf’ trying URL 'https://cran.rstudio.com/src/contrib/sf_0.5-1.tar.gz' Content type 'application/x-gzip' length 4073881 bytes (3.9 MB) =====

问题 So I have at one point had this going via Beanstalk, using Amazon Instance (2013.09) ami-35792c5c . At the time this ebextension scripts worked great when placed in the root of your repo in .ebextensions/ 00_repo.config packages: rpm: pgdg-redhat93-9.3-1: 'http://yum.postgresql.org/9.3/redhat/rhel-6-x86_64/pgdg-redhat93-9.3-1.noarch.rpm' remi: 'http://rpms.famillecollet.com/enterprise/remi-release-6.rpm' files: "/etc/yum.repos.d/pgdg-93-redhat.repo": mode: "000644" owner: root group: root

问题 Clarification: I somehow left out the key aspect: not using os.system or subprocess - just the python API. I'm trying to convert a section of a NOAA GTX offset grid for vertical datum transformations and not totally following how to do this in GDAL with python. I'd like to take a grid (in this case a Bathymetry Attributed Grid, but it could be a geotif) and use it as the template that I'd like to do to. If I can do this right, I have a feeling that it will greatly help people make use of this

问题 I have a requirements.txt with python3 package that is used to deploy a webapp that uses GDAL. When I try to install the requirements.txt using pip3 install -r requirements.txt , it fails on per the below error. I'm on Centos 7. I've tried (all in sudo su -) pip3 install --global-option=build_ext --global-option="-I/usr/include/gdal" GDAL==2.2.4 pip3 install --upgrade setuptools pip3 download GDAL yum install gdal-devel gcc pip3 install GDAL ERROR: Collecting GDAL Using cached https://files
