0 - 1m Elevation Contour for the Central Texas Coast

Summary

County- wide DEMs at 5m resolution were provided by TNRIS and mosaicked clipped to the study area. This DEM was then used to develop 1- and 2- meter contours to assist in evaluating potential sea level rise scenarios in areas not covered by the SLAMM model run. A low-pass filter was first applied to the DEM to remove any major outliers within the elevation raster. The DEM was then reclassified according to elevation, separating the DEM into 4 classes: minimum elevation up to 0 m, between 0 m and 1m, between 1 m and 2m, and above 2 m. This reclassified raster was then converted to a polygon feature class. Polygons representing 0-1 m and 1 – 2 m were then exported separately, and these were used as 1 and 2 meter elevation contour lines. [...]

Purpose

This polygon feature class was generated by the Harte Research Institute for the purpose of investigation potential sea level rise impacts on the central Texas coast for the project ICF2012 (CGP LCC 2012-002 Employing the Conservation Design Approach on Sea-Level Rise Impacts on Coastal Avian Habitats along the Central Texas Coast).
