The city of Frisco, TX located in Collin and Denton county.(A) Land cover map for 1992 based on 1992/2001 Retrofit Land Cover Change Product. (B) NLCD 2001. (C) NLCD 2011. (D–F) Land cover data reclassified into 3 categories. (G–I) Block level population data. (J–L) Population density shown in 30 m resolution grids.NLCD 2001, 2011: 11 – open water; 12 – ice/snow; 21 – developed, open space; 22 – developed, low intensity; 23 – developed, medium intensity; 24 – developed, high intensity; 31 – barren land; 41 – deciduous forest, 42 – evergreen forest, 43 – mixed forest, 52 – shrub/scrub; 71 – grassland; 81 – pasture/hay; 82 – cultivated crops, 90 – woody/wetlands, 95 – emergent wetlands.LC1992: 1 – open water; 2 – urban; 3 – barren; 4 – forest; 5 – grass/shrub; 6 – wetlands; 7 – wetlands; 8 – ice/snowAncillary data: 0 – uninhabited; 1 – urban areas; 2 – nonurban areas.
