Export GeoTiff image

Hi!

I'm new to Qt C++ . i want to build a program to export a GeoTiff satellite image and save it in my computer.

I find that writing GeoTiff files myself is too complicated and difficult for a newbie. So I searched for a tool that would help me export GeoTiff image files.

Is there anything from C++ ArcGis that can help me with that?

Hello -

Can you provide some more details - do you have your own data source, or are you needing to obtain the data? ArcGIS Runtime SDK doesn't have an export GeoTiff API, but it can read and render GeoTiffs.

ArcGIS also has the ability to export raster tiles from online basemaps. This allows you to use basemaps offline, but the data format would be a raster tile package, not a GeoTiff. https://github.com/Esri/arcgis-runtime-samples-qt/tree/main/ArcGISRuntimeSDKQt_CppSamples/Layers/ExportTiles

Thank you!!!

Yes, i want to export GeoTiff file from an online map and save it. But with the raster file output, i think GDAL can help me write GeoTiff file.
Do ArcGIS raster tile package export raster file that GDAL can read?
