Abstract

SEED shows point locations of Maine mussel seed conservation areas at 1:24,000 scale. Data for this dataset were screen digitized on a 1:24000 scale base using descriptions contained in Maine Department of Marine Resources (MDMR) rules. Coastal arcs from Maine Office of GIS 1:24000 COAST coverage were used to close polygons where needed.

Purpose

SEED was created to show locations of Maine mussel seed conservation areas.

Process Description

The Maine Office of GIS completed the conversion of all final data layers from NAD27 to NAD83 in July 1999. All the data layers were converted using the ArcInfo (version 7.2.1) NADCON conversion and the "project" command. All data was copied to double precision, projected to NAD83, and then copied back to single precision. It was decided to keep the NAD27 quad structure instead of generating new quad boundaries from NAD83 coordinates - all indexes (quads) were projected to NAD83 by using the same process previously described. All MEGIS data libraries in ArcInfo Librarian were repopulated using the NAD83 indexes and data.

Entity and Attribute Detail Citation

The ArcView shapefile and ArcGIS geodatabase formats, commonly used for Maine GIS data, carry default identifiers and attributes that are software generated and/or important for internal recordkeeping. These are listed here to avoid repetition for every layer, and may not be repeated in the attribute descriptions and definitions of each layer. Common software generated identifiers and attributes in Maine GIS data include: FID (feature identifier), Shape (feature geometry), OBJECTID and SHAPE_lengt. In addition, most GIS formats will carry fields for PERIMETER, AREA and/or LENGTH according to feature geometry. These fields are typically available by default, with the units based on coordinate system or projection units of GIS data. Most GIS software packages also provide a means to calculate these values. It is important to test any columns containing PERIMETER, AREA or LENGTH values before using them for analysis purposes. These important values can be carried from format to format and become out-dated. Verify that the values are correct. Also, in your GIS software, please view the properties of data layers for the map units used to calculate these fields, and for the units set for display purposes.

Format Information Content

MEGIS has made all vector layers, in the Maine GIS Internet Data Catalog, available in ESRI's ArcView 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.
