Loudoun County Soil Anomaly Points

Loudoun Soil Point Features are a geospatial subset of the county's soils map, detailing isolated areas like sinkholes, springs, and wet spots. The dataset is maintained by the Loudoun County Department of Building and Development and was last updated in April 2026. It includes point features for 13 distinct soil anomaly types, such as borrow pits and rock spots.

Use Cases

• Classify soil anomaly type (e.g., SP, SNK, WET) using point geometry for land suitability analysis.
• Identify locations of specific features like sinkholes (SNK) or springs (SPR) for hazard mapping and groundwater studies.
• Analyze the distribution of stony (STN) or gravelly (GRA) spots to inform agricultural land management plans.
• Integrate point features with other soils layers to create composite maps for environmental impact assessments.

Strengths

• Contains 13 distinct, coded soil point feature types (e.g., SNK, SPR, WET).
• Stored in a corporate ArcSDE Geodatabase ensuring structural integrity.
• Coordinates are in a precise state plane system (Virginia State Plane North, NAD83 HARN).

Limitations

• The row count and spatial completeness are unknown; features may have been eliminated due to scale.
• Data includes an 'Unknown' (SP) feature code, indicating potential label gaps.
• Update frequency is 'As needed', which may lead to temporal gaps for specific features.
