The interface is for the entire state within a 10 mile buffer. There are 4 layers: a 3 acre filter layer, a 5 acre filter layer, a 25 acre filter layer, and a 1 acre filter raster layer. Purpose: This dataset was created in order to define the shoreline and to provide a classified feature use in GIS systems and modeling. This data is not to be used for legal, property description, navigation, or other site specific applications. Supplemental_Information: A filtering threshold of 3-acres was used to create this land-water interface. Land and water polygons smaller than 3-acres are not visible in this data layer.

Subset scenes to bands 3, 4, 5.2. 2. Mosaic scenes in same path. 3. Classify land and water. 4. Create land/water mask. 5. Mosaic land/water mask paths. 6. Create 10 mile buffer from state boundary. 7. Cut land/water mask mosaic using buffer. 8. Eliminate land and water areas less than 1 acre, 3 acres, 5 acres, and 25 acres, creating 4 filtered land/water mask files. 9. Convert raster masks to polygon vectors. 10. Smooth the vectors. 11. Create shapefiles. 12. Add land/water class column based on grid code. 13. Reproject to Geographic NAD83 Datum The steps taken to create the 1acre filter raster layer is as follows: 1. Subset scenes to bands 3, 4, 5.2. 2. Mosaic scenes in same path. 3. Classify land and water. 4. Create land/water mask. 5. Mosaic land/water mask paths. 6.
