Gulf of Maine - Land and Water Masks (as rasters and polygons) for the Remotely Sensed Data

This personal geodatabase contains land and water masks (as rasters and polygons) for the remotely sensed data. It also contains a polygon feature class named: Spatial_Extent_Remote_Sensing_Data, which denotes the outer boundaries of all of the remote sensing data. All of these masks were derived directly from the remotely sensed imagery using geoprocessing functionality in ArcGIS 9.1.

本个人地理数据库包含了土地和水域的掩膜（以栅格和多边形形式），以及针对遥感数据的。此外，还包含一个名为 Spatial_Extent_Remote_Sensing_Data 的多边形要素类，该类表示所有遥感数据的边界。所有这些掩膜均直接从遥感影像中利用 ArcGIS 9.1 的地理处理功能生成。
