Bitmap to raster

Question

Hi I am using ArcGIS Maps SDK 200.4.0.

I have a requirement to display in-memory bitmaps as rasters on the map.

How can I convert the in-memory bitmap images to raster images so they can be displayed on the map?

I have tried to save the bitmaps as .tif files and then loading them into a raster layer - this did not work.

I have tried to add georeferencing information using GDAL and then loading them into raster layer - this also did not work.

I do not have access to ArcGIS Pro.

I have access to local server - can i use this?

Any help is appreciated.

Thank you.

Look at the MosaicDatasetRaster:
https://developers.arcgis.com/net/api-reference/api/net/Esri.ArcGISRuntime/Esri.ArcGISRuntime.Rasters.MosaicDatasetRaster.Create.html#Esri_ArcGISRuntime_Rasters_MosaicDatasetRaster_Create_Esri_ArcGISRuntime_Data_Geodatabase_System_String_Esri_ArcGISRuntime_Geometry_SpatialReference_

It has methods for adding rasters to it.

Thank you both for your responses.

I have managed to get a bitmap to display on the map by fixing my GDAL conversion, now the in-memory bitmaps are saved locally as .tif files and then I use GDAL to set the projection to WGS84 and set geo transform information like lat/long.

My question now is now I have multiple raster files, how can I mosaic them together? The mobile mosaic dataset seems like an option but I do not have ArcGIS pro and these raster files are created on the fly - I don't see how I could create the mobile mosaic dataset on the fly either.

I have looked into geoprocessing tools of local server but it seems they all require something like a .gdb file from Arcgis pro - again I don't have access to ArcGIS Pro so I'm unsure how to proceed from here.

Any help is appreciated.

Nick gives great info above. I would only add that Local Server doesn't really add much here, you should be able to use the direct raster support as outlined above.

Also, depending on what your bitmaps represent, it may be worth considering the mobile mosaic dataset to which you can add individual rasters and apply mosaic rules to effectively treat them as a single image. For more info see Add raster data | ArcGIS Maps SDK for .NET | Esri Developer.
