Lineage 

Process step
When the process occurred 2014-10-07 00:00:00
Description US Board of Geographic Names (GNIS) was used to extract 57 lighthouses for the Maine coast.. These lighthouse location points were verified using orthoimagery and NOAA nautical charts. Some of the points were moved to represent a more accurate position and were placed on or as close to the lighthouse structure as possible. A list from Wkipedia was used to locate 6 additions llighthouses that were not included in the GNIS data. These additional points were added to the dataset. Live links to lighthouse images were included from the Wkipedia site and were also coded active/inactive using data available at the time of publication.
Rationale To create a dataset that contains lighthouses of Maine.

Format information content MEGIS has all vector layers in the Maine GIS Internet Data Catalog available in ESRI's ArcGIS shapefile format. A shapefile is a simple non-topological format that stores the geometry and attribute information for a set of geographic features as a set of vector (point, line, polygon) coordinates. Shapefiles draw quickly and directly in ArcView, ArcGIS, ArcExplorer. Shapefiles are a compatible data type for many other types of GIS software. Three files are fundamental to each shapefile: .shp stores the feature geometry (shape and location information); .shx stores the index of the feature geometry; .dbf a dBASE (TM) file stores the attribute information for the features. Other index files may be created to help speed analysis and query: these file formats are .sbn .sbx .ain .aix .fbn and .fbx. In addition you may find projection .prj, and metadata .xml, files associated with shapefiles.
