Waterway Polygon, NY, NJ, PR, VI, 2018, Navteq, Region 2
NAVTEQ Waterway Polygons for the United States. The Waterway Polygons and Waterway Segments layers contain polygonal and linear features that represent water features within a NAVSTREETS coverage area. These include Rivers, Water Channels, Lakes, Bays/Harbours, Rivers, Intermittent Rivers and Canals/Water Channels that can be represented as either polygons or linear features, while other water features are typically represented as polygons. These layers are used for map visualisation. This dataset is a subset of the full NAVTEQ NAVSTREETS database.
ESRI Shape File and supplemental documentation packaged as sets of .tar and .tar.gz compressed coverage area folders. For data packaging and delivery, these NAVTEQ coverage areas are organized using 3 world areas including: Americas, Asia Pacific (APAC), and Europe, Middle East, Africa (EMEA).
requiring username and password as issued to customer by NAVTEQ. Immediate, easy, and secure download access for data and documentation through NAVTEQ's B2B website is the preferred data delivery method. NAVTEQ customers also receive email notification when new releases or updates become available for data and documentation.
NAVTEQ Product Folder: americas\usa_dca1\2011q2\D1AM09202ND1ADX, File: WaterPoly, in ESRI Shape File format. NAVTEQ data folders are organized using a 4-5 level hierarchy. The 1st level consists of 3 global areas including 1) The Americas, 2) Asia-Pacific (APAC) and 3) Europe, The Middle East, and Africa (EMEA). These 3 global areas are then divided into approximately 60 2nd level areas as countries, e.g., Argentina, regions within a country, e.g., North America DCA7, or several countries together, e.g., Spain and Portugal. The 3rd level folders correspond to a specific year and quarter release date, e.g., 2011q2. The 4th and 5th level folders use NAVTEQ's standard product file naming. The standard product file folder name will comprise up to 17 capitalized alphanumeric characters in the following format: RRCCYYQVVAAABBB.ZZ where RR = Sub Region Code, CC = Clipping/Merge Code, YY = Year Code, Q = Year Quarter, VV = version, AAA = Region Identification, BBB = Product Identification Code, and ZZ = compression method. In some cases, the data files for a NAVTEQ coverage area will be packaged in a single country folder, e.g., Thailand, in other cases, multiple sets of data files for a country will be packaged as multiple sub region folders under a single top level grouping folder, e.g., France. NAVTEQ NAVSTREETS is comprised of approximately 40 GIS layers and 30 related dbf tabular datasets. Prior to Q2 2011, the related tabular datasets were packaged as empty shapefiles with only the dbf files containing data. As of Q2, 2011, these related tabular datasets are no longer packaged as empty shapefiles and are now delivered as single dbf files. For fully describing the entity and attribute information contained in these dbf only tabular datasets, NAVTEQ does provide FGDC metadata files, and describes them using an FGDC Vector Type of Point. For areas of the world using non Latin-1 (ISO-8859-1) character sets for local language representation, NAVTEQ provides supplemental matching Unicode (UTF-8) based or "look-aside" files for many dataset attributes. When Unicode based data is available for a NAVTEQ coverage area, it will be packaged into a separate and complete NAVTEQ coverage area folder using a different Product Identification Code. This folder will contain both the main Latin-1 based and the supplemental Unicode files. The Unicode based data files will be found in the LAT subfolder, and named with .uni file extension. Empty Layers Note: Layers such as WaterWys, Adminbndy3, Adminbndy4, and MajHwys, MajHwyShield, various POI layers, etc., could potentially be empty, depending on the coverage and regional inclusion of the data. In addition, depending upon the situation, the layersAdminBndy1 and AdminBndy2 can be empty as a result of cases where regional divisions of NAVTEQ products do not align with real-world geo-political boundaries. To help users get started with viewing and using layers and data tables, as of Q2, 2011, NAVTEQ also provides an ArcGIS/ArcMap.mxd, and an MXD_Readme.txt file, located in the Region folder containing the ESRI Shapefiles. NAVTEQ data can also be used with other GIS software including MapInfo and is available in a variety of other formats including RDF (Relational Data Format), GDF (Geographic Data Format), SIF+ (Standard Interchange Format), POI XML, and ODF (Oracle Delivery Format).
