Miller County is unmistakably agricultural in the supplied 2025 data. Agriculture covers 60.15% of the county, followed by wetlands at 17.72% and forest at 12.96%. Developed land is only 6.19%, with the strongest built concentration near the county center around Colquitt. This Miller County Georgia Land Cover Map shows how a small county seat, extensive cropland, wet lowlands, and scattered wooded blocks fit together.
The article uses four WebP previews: current land cover, a forest-and-farmland view, fractional impervious surface, and a 1985–2025 endpoint comparison. Four original 2480 × 1754 JPG maps are packaged in one ZIP for reports, lessons, county profiles, and presentations.
Table of Contents
Cropland dominates almost every part of the county
Yellow agricultural cover is continuous enough to set the visual character of the map. Large field blocks occupy much of the northeast, east, south, and west, and even the more wooded sections remain surrounded by cropland. At 60.15%, agriculture covers more than three-fifths of the county, so the other classes mostly appear as islands, bands, and corridors within a farm-dominated background.
Wetlands are the second-largest class at 17.72%. Teal areas are especially broad in the west and northwest, continue through the center toward the south, and reappear in a large southeastern patch. In several places they follow branching shapes between fields. Those patterns are useful for recognizing wet lowlands within the agricultural landscape, although the map does not label streams or establish regulatory wetland boundaries.
Forest covers 12.96%. The largest green block sits west of the center, with other wooded areas in the northwest, southeast, and smaller pieces throughout the farm country. Developed land accounts for 6.19% and is visually concentrated enough that the central settlement stands out even though its countywide share is small.
Colquitt is the main built center in an otherwise dispersed rural landscape
Miller County’s official history identifies Colquitt as the county seat and the county’s only incorporated city. On the impervious map, the largest cluster of dark red and orange values sits close to the center, making Colquitt the most useful reference for the principal built footprint. Thin lighter traces extend outward along several road-shaped corridors before fading into the agricultural matrix.
Smaller hard-surface groups appear north of the main center and at a few eastern and southern locations. They are separated by large areas with little or no impervious cover. This distribution fits a county where settlement is concentrated in one small city and scattered rural communities rather than a continuous suburban belt.
Mean impervious cover is 1.08%, and 0.23% of Miller County reaches 50% impervious surface or more. Developed land is 6.19%, a wider category that can include lawns, trees, yards, and bare ground around roads and buildings. Fractional impervious cover focuses on roofs, pavement, parking areas, and other hard surfaces that resist infiltration.
The vegetation map confirms that agriculture overwhelms the smaller natural classes
Removing the strong developed colors makes the size of the agricultural footprint even clearer. The eastern half contains long stretches of nearly continuous cropland, while the western-central portion has a larger mix of forest and wetlands. Southeastern Miller County also contains a distinct wetland-and-forest complex within the surrounding fields.
Miller County’s official background notes a long history of cotton, peanut, and corn production. Current UGA Extension materials continue that agricultural emphasis and describe local work on peanut variety testing, while recent county impact data list peanuts, cotton, and corn among the top commodities. These sources help explain the agricultural setting, but the raster cannot identify a particular crop in an individual yellow cell.
Shrubland is 1.45% and grassland 1.42%, while open water is only 0.09%. Those small percentages mean the countywide story is better explained through agriculture, wetlands, and forest than through minor classes. Small ponds, narrow drainage channels, and grass strips can also be generalized at the 30-meter source resolution.
The 1985–2025 difference map shows more than development change
The total class difference between the two endpoint years is 15.58%. This is the share of raster cells assigned different categories in 1985 and 2025. It is not the amount of Miller County that became urban, and it should not be subtracted from the current 60.15% agriculture figure to estimate historical farmland.
The printed summary lists 5.57% other difference, 3.99% forest loss, 3.71% agricultural loss, and 1.07% classified to developed. Developed-change red is concentrated around the central settlement and a smaller northern cluster. Forest-loss orange, agricultural-loss yellow, and other-difference purple are scattered much more widely through the county.
Wetland difference appears in the legend without a separate printed percentage. The missing value should not be reconstructed by subtraction and presented as an official rate. The map also notes that classification variation may be present, so imagery date, seasonal conditions, mixed pixels, and classification decisions can contribute to some endpoint differences.
Agricultural importance is real, but mapped acreage and farm economics are different measures
UGA Extension’s recent Miller County impact report gives a farm-gate value and identifies peanuts, cotton, and corn as leading commodities. Those economic measures answer a different question from the land-cover map. The 60.15% agriculture figure measures mapped surface area, not crop value, yield, or the share of local income generated by farming.
The Georgia Department of Community Affairs maintains a joint comprehensive plan for Miller County and Colquitt. Planning documents deal with growth, infrastructure, resource management, and future land use. Annual NLCD instead classifies what covers the ground in a given observation year. A yellow cell is not a zoning district, and a red cell is not a permit boundary.
Annual NLCD uses 30-meter raster cells, so a single square can contain a field edge, trees, a road, and part of a building while receiving one predominant class. That is why these maps are useful for county patterns but not parcel surveys. Exact ownership, wetland jurisdiction, property lines, and building decisions require current local or federal records.
Choose the map according to the question you need to answer
Start with the 2025 countywide map when the goal is to explain Miller County’s agricultural dominance and the location of wetlands, forest, and the Colquitt settlement. The vegetation view is better for comparing cropland with wooded and wet areas. Use the impervious map for roofs and pavement around the main settlement, and reserve the endpoint map for a separate discussion of 1985–2025 classification differences.
Each original JPG measures 2480 × 1754 pixels and works well for reports, lessons, and presentations. The package does not identify the files as meeting an A3 high-resolution reference, so test a proof before relying on them for large-format printing.
Frequently Asked Questions
What is the dominant land-cover class in Miller County?
Agriculture is the largest class in the supplied 2025 summary at 60.15%. Wetlands follow at 17.72% and forest at 12.96%, making the county strongly agricultural with substantial wet and wooded areas.
Why is developed land 6.19% while mean impervious cover is only 1.08%?
Developed classes can include lawns, trees, yards, and bare ground around buildings and roads. The impervious product isolates the harder surfaces such as roofs, pavement, and parking areas.
Does the 15.58% endpoint difference show how much farmland disappeared?
No. It counts cells with different class labels in 1985 and 2025. The summary separately lists 1.07% classified to developed, 3.99% forest loss, 3.71% agricultural loss, and 5.57% other difference.
