GDAL Tutorial #2: Converting, Resampling, Reprojecting, Clipping

This second GDAL tutorial explains the processing of geospatial raster data using GDAL and the command line interface. The following commands are introduced:
- gdalinfo to obtain information on a given raster dataset
- gdal_edit to manipulate this information
- gdal_translate to convert between different raster formats and resample data to a different resolution
- gdalwarp to change the coordinate reference system, resample, and/or clip the input data to a vector layer or coordinate extent

Chapters:
0:00 Introduction
0:52 Command Line Interface
3:54 Data and gdalinfo
6:07 gdal_edit
6:50 gdal_translate
11:42 gdalwarp

Thank you very much for all your effort. I have spent hours searching for a Get Started tutorial and this is absolutely fantastic.

[MsTooteh]

These tutorials are so incredibly helpful. Thank you!!!

Thanks so much for these videos -- I'm just getting into using CLI for geodata after using ArcGIS for years.

just what i needed as a newby in commandline work :-)

[maneeshpk]

Please keep making more videos. Your vids are really helpful!!

I (as a windows user, not familiar with the command line) spent some time finding the proper command line terminal. It worked for me when i opened the terminal from the Qgis browser (right click on a folder or even quicker: your working folder>> open in terminal). The windows terminal (maybe i used the wrong one) did not work properly. But from the browser in Qgis i had no problem at all to execute the commands.

Thanks for the tutorial, very awesome! Just wondering where to download your data for reproducing your demo? Thanks.

🙂

first of all congratulations for the content!!!

would you know how to inform how the code would be to convert a raster (orthomosaic) tiff into ecw???

[DiantiFarhana]

Hi. Thank you so much for this video it helps me alot. I plan to transform many Tiff data to Asc data. Do you know how to change it directly at the sametime? since if we use Gdal_translate one by one that would really hard work for me. Thank you.

Hello! Thank you for the great videos! I have a question: how to set a path to GDAL installation folder in terminal, cause when I try to run GDAL, i`m getting next message: error while loading shared libraries libpoppler.so.91 cannot open shared object file no such file or directory
Thank you!

[mdkashif]

Hi there, thank you for this nice tutorial! Would you please tell how can the output path be specified?

[mdkashif]

Excellent! Your videos have proven to be immensely helpful to me.
I've a small question. How can I clip an image when I've corner coordinates, and the clip has to be done in spyder (or in jupyter notebook) not in terminal? Would you please help me. This is my assignment task. Thank you!

[youseffirouz]

Hello, many thanks for your nice tutorials. A question: I have a '1' band geotiff, and i have a list of targets (in RGB codes) which i need to find on the geotiff file. How can i correlate those rgb codes to single band geotiff.
Many thanks in advance.

[sangmaneewutthip]

Please tell me about the beginning of the project on how to do the steps. I still do not understand how to access gdal or start learning gdaltutorial like shapefile, store it or get it from. Thanks.

What if at reprojecting the data, the original data had a certain compression (like lzw) and predictor? If I do not set it, the data might change in size and even in some pixel values

[comeinwiththerain]

Hello, I downloaded an hdf file from the MODIS LP DAAC website but it doesn't show me the subsets when I use the gdalinfo command with it. The error just says that the format is not supported. Can anyone tell me what the issue might be?
