Horry County Government 07/31/2008 gisdev.GISDBA.Structures2010 vector digital data withheld gisdev.GISDBA.Structures2010 Fugro Earthdata, Inc. was tasked by Horry County, SC with a 2D planimetric update of their existing structure, transporation, impervious surface, and hydro polygon datasets. This was accomplished through utilizing the new 2010 6 inch GSD orthophotography. The purpose of the update was to provide Horry County with an up to date planimetric data set representing impervious surfaces throughout the county. The structure data was one feature class updated as part of the of impervious planimetric update. en 02/15/2010 unknown ground condition Complete Annually -79.347322 -78.555954 34.297231 33.561739 2503285.499850 2738132.890062 637505.789953 900514.250156 Water Hydro All data is the property of Horry County, SC and cannot be used with permission.

This validation ensures correct formating and attribute values. The hydro planimetric update was completed by identifying areas of change when the 2009 data was placed over the 2010 orthophotography. When identified new data was collected and attributed, features with additions were updated, and missing features were deleted. Areas obscured by dense foliage were not updated.

The existing 2009 Horry County planimetric data was converted to a dgn file format for use with MicroStation V8. The attribute information contained in the 2009 data was converted to a seed/symbolgy file for use with MicroStation. Addtional information was added to the seed file to ensure new attributes were captured when data was updated. In Microstation the planimetric data was brought in over the 2010 orthophotography. A technician manually reviewed the existing data against the orthos and made upates, additions, and/or deletions were needed to align the planimetrics to the orthos. Attribute information was updated if data was updated or added. Once the entire project area was completed in MicroStation the data was run through some automated QC checkes to check for data collection errors. If found errors were corrected. Once the data passed the the automated QC the data was converted to a polygon ESRI compatible format. A QC check was performed in ArcMap. A final deliverable was prepared in the customer specified geodatabase format. 06/01/2010 Vector Simple FALSE 0 TRUE FALSE coordinate pair 0.000328 0.000328 international feet D_North_American_1983_HARN Geodetic Reference System 80 6378137.000000 298.257222 GCS_North_American_1983_HARN NAD_1983_HARN_StatePlane_South_Carolina_FIPS_3900_Feet_Intl 1.000000 Explicit elevation coordinate included with horizontal coordinates gispublic_DBO_Structures2020 Feature Class 0 OBJECTID Internal feature number.
