Abstract
BOATLNCH depicts state-managed and state-assisted boating facility locations throughout Maine at 1:24000 scale or better recorded by the Boating Facilities Division of the Bureau of Parks & Lands. Maine's Bureau of Parks and Lands, Maine's Department of Inland Fisheries & Wildlife and land owners provide access to lakes, ponds, rivers, and the coast at 456 locations. Sites may have gravel or hard-surfaced ramps and may include boarding floats, rest rooms and picnic tables. A few sites have canoe or carry-in access only. Some ramps on tidal waters may be useable only at high tides and are designated "part-tide" facilities. A brochure listing all the boat launches is available by calling (207) 287-4952 or you can view an online version at http://www.state.me.us/doc/parks/programs/boating/index.html .
Purpose
BOATLNCH provides digital mapping of Maine boating facilities on both coastal and inland waters, and shows the locations of state-managed and state-assisted boat launches in Maine.
Supplemental Information
Use scale appropriate to 1:24000 to map most of these features. Those attributed with CONFIDENCE equal to 1 are known to be within 3 meters of their actual location and can be mapped at a larger scale of approximately 1:2500. Those attributed with CONFIDENCE of 2 are known to be within 12 meters of their actual location. Those attributed with CONFIDENCE of 3 are known to be within 24 meters of their actual location.

Attribute Accuracy Report
Attributes have been drawn from tabular data maintained by the Boating Facilities Division, Bureau of Parks and Lands, Maine Department of Conservation. Some town names by the originator do not correspond to standard common names, as listed in "Standard Geographic Codes for Maine Minor Civil Divisions", 1971. MIDAS numbers have been compared for accuracy to MDIFW/MEDEP MIDAS update 2003. MEDEP and other hydrography names can be related using the MIDAS number. Hydrography feature names in BOATLNCH are those assigned by MEDOCBPL Boating Facilities Division and do not necessarily correspond with either USGS GNIS names or MEDEP hydrography names.
Logical Consistency Report
Spatial topology is clean and free of errors. Some of the points have been offset from the collected location, in order to achieve a visual compilation with basemaps and available imagery.
Completeness Report
Data set is complete.
Horizontal Positional Accuracy Report
Horizontal accuracy for the GPS collection is not documented at this time. Horizontal positional accuracy for the collected data has been spot checked by visual comparison to digital raster graphics of the U.S. Geological Survey 7.5 minute series maps. Sampling suggests 90% of the points are expected to compile correctly to this data at 1:24000 scale. The CONFIDENCE field indicates the level of accuracy one could expect from a specific location. Those features with a CONFIDENCE of 1 are known to be within 3 meters of their actual location and so can be mapped at a larger scale, approximately to 1:2500. Those features with a CONFIDENCE of 2 are known to be within 12 meters of their actual location. Those attributed with CONFIDENCE of 3 are known to be within 24 meters of their actual location.
Horizontal Positional Accuracy Value
3
Horizontal Positional Accuracy Explanation
CONFIDENCE 1-GPS data were differentially corrected using base station data. Parameters set for GPS collection typically provide accuracy ranges of 2 to 5 meters.

Other Citation Details
This citation is for the first official Standard Geographic Code endorsed and adopted by the Governor of Maine, on July 1, 1971. Geocodes have undergone subsequent revisions, all of which were "officially" rolled back to this 1971 list by Maine's Information Services Policy Board (ISPB), as of January 2000. In 1971, all Maine state agencies were requested to implement these five digit geocodes, in agency information systems, to build a base of data for Maine's Minor Civil Divisions (MCDs) and to promote data sharing. Data coded by MCD may subsequently be summarized by any other type of region, administrative district, natural area, etc. The first two digits of the geocode represent the federal code (FIPS) for Maine counties, the remaining three digits uniquely identify each of Maine's MCDs and Reservations. As an information service to state agencies and the public, geocodes for Maine, are now maintained, updated and made available for download, in comma delimited text and .dbf format, through the Maine Office of Geographic Information Systems (MEGIS) Data Catalog

Process Description
Updated BOATLNCH data set, a quick check of MIDAS numbers with a recent MIDAS update (MEDEP/MDIFW) turned up the following that were corrected in a MIDAS text format field, and a MIDAS number field prior to publicationMEDOC/MEDEP notified of the updates 03/15/2004.Most are related to the MIDAS standard four digit format, but here are two numbers that I believe need correction.Grace Pond was 0150 should be 0152Crystal(Beal) Pond was 3226 should be 3626MIDAS numbers have a standard four digit format and all leading zeroes should be preserved up to four digits, so you may want the correct format on the following:Great East Lake was 03922 should be 3922Jones Pond was 05466 should be 5466Little Ossipee Pond was 05024 should be 5024Penman Pond 113 sb 0113Porter Lake 12 sb 0012Spednic Lake 121 sb 0121Mountain View Pond 269 sb 269Lake Hebron 301 sb 0301Little Pennesseewassee Pond 367 sb 0367Flagstaff Lake 38 sb 0038Moosehead Lake 390 sb 0390Arnold Brook Lake 409 sb 0409First Roach Pond 436 sb 0436Wesserunsett Lake 70 sb 0070Fahi Pond 74 sb 0074Center Pond 760 sb 0760Embden Pond 78 sb 0078Sebec Lake 848 sb 0848Lake Onawa 894 sb 0894Seboeis Lake 954 sb 0954Upper Narrows Pond 98 sb 0098Ambajejus Lake 982 sb 0982South Twin Lake 982 sb 0982Carry MIDAS in a text field. It is correct to carry any numbers not used for calculation as text. Also this preserves the MIDAS standard four digit format with leading zeroes.Some agencies carry MIDAS as a number field. Often this happens unintentionally when TEXT data type isn't specified on import of tabular data. A number field strips off the leading zeroes which makes comparisons and relationships problematic, and causes quite a bit of confusion. For Maine GIS data publications, we use an option to cover both data types, that is to carry the MIDAS identifiers in a four digit format text field, and also as a numeric field. Both of these fields have been added to BO

Entity and Attribute Overview
BOATLNCH contains attributes that describe location, waterbody, access, and facilities at the boat launch. These include: LONGITUDE, LATITUDE, GEOCODE, MCD, COUNTY, WATERBODY, TYPE of RAMP surface, width, length and grade, TYPE, FLOATS, FEES, FACILITY, MIDAS number, FILE_No, OWNERSHIP, S_Or_L, TIDE COMBO, RIGPARKING, VEHICLE PARKING, ADA, YEAR IN USE,LAT/LONG SOURCE, and LAT/LONG CONFIDENCE. Some town names used by the originator do not correspond to standard common names, as listed in "Standard Geographic Codes for Maine Minor Civil Divisions", 1971. The field MCD was added to list the standard common names used in Maine GIS data sets. MIDAS numbers have been compared for accuracy to MDIFW/MEDEP MIDAS update 2003. MEDEP hydrography names can be related using the MIDAS number. Hydrography feature names in BOATLNCH are those assigned by MEDOCBPL Boating Facilities Division and do not necessarily correspond with either USGS GNIS names or MEDEP hydrography names.
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_length. 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.

These include: LONGITUDE, LATITUDE, GEOCODE, MCD, COUNTY, WATERBODY, TYPE of RAMP surface, width, length and grade, TYPE, FLOATS, FEES, FACILITY, MIDAS number, FILE_No, OWNERSHIP, S_Or_L, TIDE COMBO, RIGPARKING, VEHICLE PARKING, ADA, YEAR IN USE,LAT/LONG SOURCE, and LAT/LONG CONFIDENCE. Some town names used by the originator do not correspond to standard common names, as listed in "Standard Geographic Codes for Maine Minor Civil Divisions", 1971. The field MCD was added to list the standard common names used in Maine GIS data sets. MIDAS numbers have been compared for accuracy to MDIFW/MEDEP MIDAS update 2003. MEDEP hydrography names can be related using the MIDAS number. Hydrography feature names in BOATLNCH are those assigned by MEDOCBPL Boating Facilities Division and do not necessarily correspond with either USGS GNIS names or MEDEP hydrography names.
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_length. 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.
