I have two raster files, A and B (see Table below). I am looking to reproject B to the same projection as A, and also resize (aggregate) pixels in B to the same size as A (0.5 x 0.5 degrees) so they can be stacked. I have been trying to reproject raster B to the same gcs as A using the "Reproject Raster Tool" and selecting the coordinate system to reproject to using the "import from existing data set icon". This works fine, but I've noticed that when B is projected into degrees the pixels are no longer square ---- x: 0.00905151988556 and y: 0.00904189581054. When I go to resize the reprojected B to 0.5 x 0.5 pixel size, the resize tool auto-corrects my desired pixel size to x: 0.50000110 and y: 0.49999425. How can I solve this problem? Many thanks for the assistance! Metadata A B Projcs NA Sinusoidal Geogcs GCS_WGS_1984 GCS_WGS_1984 Datum D_WGS_1984 D_WGS_1984 Spheroid WGS_1984, .637... WGS_1984, .637...
