How do I load a catalog of RPF (CADRG) Map tiles?

Question

How do I load a catalog of RPF (CADRG) Map tiles using the Java version 10.2.4 or version 100? I was able to load a single tile using  RasterLayer rasterLayer = new RasterLayer(new FileRasterSource("filepath")) but I can't seem to find the API to load the directory full of RPF/CADRG/NITFS files as the base map similar to what I get when we use ArcGISTiledMapServiceLayer.

Geoff,

Actually, the basemap is in 102100 WKID and your data in 4326 WKID. Check what is happening when ensuring the same spatial reference for all layers. Just add as a basemap this service ESRI_Imagery_World_2D (MapServer)  which is in 4326 WKID. Do the RPFs appear on the map? Do the align correctly? If negative, coordinate system is not the issue you are looking for.

Adam,

Thanks again for your quick reply. I looked into creating a mobile mosaic data set, but I fear my users would prefer to just point my app to the RPF files and have them loaded up instead of having to do a conversion process with ArcGIS Desktop first. Unfortunately, I can't share the files with anyone. But I added a few lines to see what was going on with the spatial reference.

layer.addDoneLoadingListener(() -> {
   SpatialReference sr = layer.getSpatialReference();
   if (sr != null)  System.out.println(sr.getWKText());
});

and

map.addDoneLoadingListener(() -> {
   System.out.println(map.getSpatialReference().getWKText());
});

I get...
PROJCS["WGS_1984_Web_Mercator_Auxiliary_Sphere",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Mercator_Auxiliary_Sphere"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",0.0],PARAMETER["Standard_Parallel_1",0.0],PARAMETER["Auxiliary_Sphere_Type",0.0],UNIT["Meter",1.0]]

Which looks like the base map and the Raster Layers are both the same projection? Am I reading that right? Should set the z-order of the raster images or something?

Geoff,

Regarding  mosaic datasets, please refer to ArcGIS documentation What is a mosaic dataset?—Help | ArcGIS for Desktop. Speaking about mobile mosaic dataset, you can create those using this tool Mosaic Dataset To Mobile Mosaic Dataset—Data Management toolbox | ArcGIS Desktop.

Referring to the issues with RPF files, I can only suspect it is related to their spatial reference, but without any sample data I cannot say anything 100% sure.

Adam
