Abstract:
Five foot contour elevations for the St. Johns River Water Management District, lines only. In some areas, the elevation increment is 10 feet rather than 5.

The topography layer was digitized from 238 USGS 24K quad mylar separates, which are available in Central Files. The work was done in the late 80s and early 90s, under two different contracts covering different sections of the district. The first contract was for linework only; polygons were not created or attributed. A subsequent contract specified that polygons were to be created and attributed in addition to the arc attribution.

The topography database currently does not include a sea level shoreline. As a result, land mass between sea level and five feet is not represented. No inland shorelines are represented. No water bodies are delineated. some quads have ten foot instead of five foot contours. USGS Quad boundary ARCS are not coincident with contiguous Quad boundary arcs.

Purpose:
Vectorized elevation information for SJRWMD in feet in 5 or 10 foot increments.

Process_Description:
Some quads on the Georgia border were in meters. The topos in METERS have been converted by Marvin Williams: added an item called zcoord2 defined as 4,12,f,2 calc zcoord2 = elev and multiplied by 3.28, added 1.0 to all zcoord2 and calc back to elev (3,3,i) truncating all numbers right of decimal, resulting in closest feet-to-meter relationship. METRIC: to161 Gross, to162 St. Mary's, to163 Fernandina Beach.
