Motivation: Multiple coronavirus genomes are normally organized by genomic information in a phylogenic tree to illustrate evolutionary variations. A novel scheme is represented to arrange various coronavirus genomes by two genomic indexes as 2D maps. Results: For a genome, two unique invariants of genomic indexes provide an absolute position on a 2D region in real measurements. Clustering effects are provided complementary from Phylogeny technology. Samples of seventeen coronavirus and twenty-six SARS-CoV-2 genomes from various countries are selected. This provides an efficient scheme to identify variations of SARS-CoV-2 strains for better identifications on both complicated coronavirus clusters and SARS-CoV-2 group of viral evolution in intermediate and original hosts on selective environments.
