Coastline
Description
Seamless dataset for Antarctic coastline applicable to all zoom levels. Data is a compendium of three line/polygon datasets which should display well at all zoom levels. Highest resolution data prepared Cooper A.P.R BAS 2011 from various sources. For the line data, each segment is attributed with metadata concerning its source, updater and update time. Last updated January 2013, Fretwell P, BAS from remote sensing imagery dating from 2011.
Main areas of update: Antarctic Peninsula and South Orkney Islands. This is the most accurate vector data for land south of -60. Medium resolution data has been generalised from the high resolution dataset using ArcGIS generalisation tool with maximum offset of 100m. Low resolution data has been generalised from the high resolution dataset using ArcGIS generalisation tool with maximum offset of 1km. This dataset has been styled with the polygon data having transparent fills. This enables the overlaying of the coastline on other data.
