Summary

Ambulance data were updated for Maine as part of a data stewardship agreement with the USGS to provide infrastructure data for the National Structures Dataset. These data are intended for use in general mapping alone or with other data themes to produce general reference maps. Maps may serve as base maps for special purpose mapping

Description

Structures data contains name and location data for selected manmade facilities. These data are designed to be used in general mapping and analysis of structure related activities using a geographic information system (GIS) For mapping purposes, structures can be used with other GIS data themes to produce general reference maps as a base map dataset.

Version ARC Version 9.x
Specification ArcView Shapefile Format
File decompression technique Data available from this website is in .zip compressed format.
Format information content MEGIS publishes all vector layers in the Maine GIS Internet Data Catalog in ESRI's 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 and 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.

Overview Description
Entity and Attribute Overview The specific attributes for ambulance were provided by the Maine Office of GIS along with many other authoritative sources that were contacted for verification.


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.

Attribute Accuracy
Attribute Accuracy Report
                            Attribute accuracy is tested by manual comparison of the source with hard copy printouts and/or symbolized display of digital files. The dataset attributes have been carefully examined for accuracy based on existing source materials. Attribute information was collected from various individual sources. Please report errors to Maine Office of GIS.
                          
Logical Consistency Report
                        Logical consistency checks were conducted during preparation of the spatial features and attributes. The point data corresponds to building locations based on address location and orthoimagery interpretation. Spatial topology meets "Data Standards for Maine Geographic Information Systems", June 2002.
