Elevation and sampled terrain profile (USGS EPQS / 3DEP)

Returns USGS EPQS transects plus NC or USGS 3DEP elevation, slope, and aspect where available, for agents checking terrain at an address. Each raster estimate carries its source and vintage; missing data stays unavailable. Not a survey, drainage analysis, or engineering conclusion. National. Direct flat-body route for this one free resource; no API key, payment, or catalog wrapper. Return only the cited bounded evidence described here; this route never produces a paid brief or full report.
