VDep is based on changes to species composition, structural stage, and canopy closure.\n\n### Bands\n\n\n**Pixel Size**\n\n30 meters\n\n**Bands**\n\n| Name | Pixel Size | Description |\n|--------|------------|---------------------------|\n| `MFRI` | meters | Mean Fire Return Interval |\n\n**MFRI Class Table**\n\n| Value | Color | Description |\n|-------|---------|-------------------------------------------|\n| 1 | #0b0080 | 0-5 Years |\n| 2 | #3800a1 | 6-10 Years |\n| 3 | #470087 | 11-15 Years |\n| 4 | #9300b0 | 16-20 Years |\n| 5 | #bf00ac | 21-25 Years |\n| 6 | #cf008a | 26-30 Years |\n| 7 | #de0059 | 31-35 Years |\n| 8 | #f00028 | 36-40 Years |\n| 9 | #e60000 | 41-45 Years |\n| 10 | #ff4d00 | 46-50 Years |\n| 11 | #ff8400 | 51-60 Years |\n| 12 | #ffbf00 | 61-70 Years |\n| 13 | #fffb00 | 71-80 Years |\n| 14 | #fff642 | 81-90 Years |\n| 15 | #fff782 | 91-100 Years |\n| 16 | #fffac4 | 101-125 Years |\n| 17 | #d4de8a | 126-150 Years |\n| 18 | #9dbf58 | 151-200 Years |\n| 19 | #64a132 | 201-300 Years |\n| 20 | #4b8c23 | 301-500 Years |\n| 21 | #146600 | 501-1000 Years |\n| 22 | #004700 | \u003e 1000 Years |\n| 111 | #0000ff | Water |\n| 112 | #c8ffff | Snow / Ice |\n| 131 | #4e4e4e | Barren |\n| 132 | #b2b2b2 | Sparsely Vegetated |\n| 133 | #e1e1e1 | Indeterminate Fire Regime Characteristics |\n\n### Image Properties\n\n**Image Properties**\n\n| Name | Type | Description |\n|--------------|--------|-----------------------------------------------------|\n| MFRI_classes | DOUBLE | Class values of the mean fire return interval. |\n| MFRI_names | STRING | Descriptive names of the mean fire return interval. |\n\n### Terms of Use\n\n**Terms of Use**\n\nLANDFIRE data are public domain data with no use restrictions, though if modifications\nor derivatives of the product(s) are created, then please add some descriptive modifier\nto the data set to avoid confusion.\n\n### Citations\n\nCitations:\n\n- The suggested way to cite LANDFIRE products is specific to each product,\n so the model for citation is provided, with an example for a particular product.\n Producer.
