I have a very large raster layer (67g uncompressed) that was merged from multiple tif files in ArcGIS Pro. However, I have not been able to get it in the correct location (USA) and it is displaying over Africa.
I first merged the original tif files using the 'Mosaic to New Raster Tool' For these settings, I ensured that the 'Spatial Reference for Raster' matched (NAD_1983_Albers), 'Pixel Type' (16 bit unsigned), 'Cell Size' (30), 'Number of Bands' (1), 'Mosaic Operator' (Last), 'Mosaic Colormap Mode' (First).
Since this did not work, I tried merging the original files again with the 'Mosaic to New Raster Tool' using 'WGS_1984_Web_Mercator_Auxiliary_Sphere' for my 'Spatial Reference for Raster'. No luck.
I then used a few different tools applied to the raster layer or map layer instead but I haven't had any luck. What I have attempted thus far:
'Define Projection Tool' to match the raster layer (NAD_1983_Albers) to the base map layer ('WGS_1984_Web_Mercator_Auxiliary_Sphere').
'Project Raster Tool' to match the raster layer (NAD_1983_Albers) to the base map layer. 'Output Coordinate System' set as 'WGS_1984_Web_Mercator_Auxiliary_Sphere', 'Geographic Transformation' set as 'NAD_1983_To_WGS_1984_5', 'Resampling Technique' set as 'Nearest neighbor', 'Output Cell Size' set as the merged raster layer, 'X and Y' as 30.
I then tried transforming the base map layer's Coordinate System by right clicking the map layer > Properties > Coordinate Systems to see if the base map would align with the raster layer. I tried Geographic Coordinate Systems (a) changing to 'NAD 1983 Albers', (b) changing to 'NAD 1983', (c) changing to 'NAD 1983 (2011); I tried Projected Coordinate Systems (d) changing to 'NAD 1983 (2011) Contiguous USA Albers', (e) changing to 'NAD 1983 Contiguous USA Albers'.
I then tried to manually enter the Coordinate system by hitting Properties > Coordinate Systems > Add Coordinate System > New Geographic Coordinate System and inputing the information embedded in the raster data.
I then tried to manually enter the Coordinate system by hitting Properties > Coordinate Systems > Add Coordinate System > New Projected Coordinate System and inputing the information embedded in the raster data.
The information for the raster layer provided by the author of the layer:
Projection type: Projection transform: List (6 elements) wkt:
SPHEROID["GRS 1980", 6378137.0, 298.2572221010042,
The Spatial Reference information for my merged raster layer from ArcGIS is as follows:
Projected Coordinate System: NAD 1983 Albers,
Linear Unit: Meter (1.0),
false easting: 0.0,
false northing: 0.0,
central meridian: 0.0,
standard parallel 1: 29.5,
standard parallel 2: 45.5,
latitude of origin: 0.0,
Geographic coordinate system: GCS North American 1983,
Angular unit: Degree (0.0174532925199433),
Prime Meridian: Greenwich (0.0),
Datum: D North American 1983,
Spheroid: GRS 1980,
Semimajor Axis: 6378137.0,
Semiminor Axis: 6356752.314140356,
Inverse Flattening: 298.257222101,
As you can see, the only differences in Spatial Reference information is the 'Central Meridian' and 'Latitude of Origin'. I have attempted to move the base map layer to match these values in the Properties > Coordinate Systems > Add Coordinate System > New Projected Coordinate System but that did not work. I have tried to find resources online on how to change the 'Central Meridian' or 'Latitude of Origin' of a raster layer specifically but haven't had any luck. I am at my wits end trying to solve what seems to be a very simple fix. This roadblock is stalling progression for a dissertation chapter.
