  • Drinking Water; water quality and public water system inventory database for use by small regulatory programs such as regional tribal drinking water programs, the Navajo Nation, or American Samoa.

  • Major hydrological basins and their sub-basins. This dataset divides the African continent according to its hydrological characteristics. The dataset consists of the following information:- numerical code and name of the major basin (MAJ_BAS and MAJ_NAME); - area of the major basin in square km (MAJ_AREA); - numerical code and name of the sub-basin (SUB_BAS and SUB_NAME); - area of the sub-basin in square km (SUB_AREA); - numerical code of the sub-basin towards which the sub-basin flows (TO_SUBBAS) (the codes -888 and -999 have been assigned respectively to internal sub-basins and to sub-basins draining into the sea)

  • 2009 water sample results of unregulated livestock water sources on the Navajo Nation. These unregulated water sources were sampled as part of EPA's work on the multi-agency Five-Year Plan to address uranium contamination on the Navajo Nation.

  • This dataset was created by Land Information New Zealand to be used in conjunction with the [Fire and Emergency NZ Localities dataset](https://data.linz.govt.nz/layer/104830-fire-and-emergency-nz-localities/) to identify and provide official locality names where a name exists in the New Zealand Gazetteer. The Fire and Emergency NZ Localities dataset currently contains many names that are not the official names for those features, suburbs or localities. The New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa) Act 2008, [Section 32](http://www.legislation.govt.nz/act/public/2008/0030/30.0/DLM1065412.html) requires all official documents to identify names which are not the official place names as recorded in the [New Zealand Gazetteer](https://gazetteer.linz.govt.nz/). As such this table identifies locality names and the matching official name where an official name in the Gazetteer exists, but Locality name differs from it. It does not take into account any differences in Locality boundaries and the boundary definition of place names in the Gazetteer. This table is a best endeavour and not comprehensive, but will improve over time. Feedback can be sent to linzdataservice@linz.govt.nz

  • This dataset provides river name polygons for mainland New Zealand. It is part of a pilot to understand the benefit of combining river names and location, and making these openly available through the LINZ Data Service. Unnamed rivers are also included in this dataset. **How this data can be used** Together with the [NZ River Name Lines (Pilot)](https://data.linz.govt.nz/layer/103632) dataset, these are the first openly available datasets with NZ river names attributed to geometry features (lines and polygons). This data can be used for searching for a named river and zooming to its extents, extracting geometries of a named river, creating digital cartographic products displaying river names, and analysing other features against named rivers (e.g. identifying buildings or properties within a specified distance of a particular river). **Data vintage** The river names and extents in this dataset are based on the cartographic text shown on NZ Topo50 maps as of December 2018, and are an approximation and should not be taken as official. Further details are included in the 'Naming Extents Methodology' section in the 'Lineage' of this metadata. Please refer to the [NZ River Name Lines and Polygons (Pilot) Data Dictionary](https://nz-river-names.readthedocs.io/en/latest/introduction.html) for detailed metadata and information about this dataset. **Related data** [NZ River Name Lines (Pilot)](https://data.linz.govt.nz/layer/103632) - contains smaller rivers captured as line features instead of polygons. We recommend using the two river name datasets with the following NZ Topo50 layers for connectivity and visualisation of inland hydrographic features. - [NZ Coastlines (Topo, 1:50k)](https://data.linz.govt.nz/layer/50258) - [NZ Island Polygons (Topo, 1:50k)](https://data.linz.govt.nz/layer/50288) - [NZ Lagoon Polygons (Topo, 1:50k)](https://data.linz.govt.nz/layer/50292) - [NZ Lake Polygons (Topo, 1:50k)](https://data.linz.govt.nz/layer/50293) - [NZ Pond Polygons (Topo, 1:50k)](https://data.linz.govt.nz/layer/50310) - [NZ Swamp Polygons (Topo, 1:50k)](https://data.linz.govt.nz/layer/50359) The [NZ River Name Lines and Polygons (Pilot) Data Dictionary](https://nz-river-names.readthedocs.io/en/latest/introduction.html) provides details on how to download the matching time period snapshots of this data. **Please note** - Official geographic names as listed in the [New Zealand Gazetteer of place names](https://www.linz.govt.nz/regulatory/place-names/find-place-name/new-zealand-gazetteer-place-names) must be used in all official documents as per the New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa) Act 2008. - This pilot dataset is unlikely to be updated, however feedback will be used for future enhancements to LINZ river datasets. --- **APIs and web services** This dataset is available via ArcGIS Online and ArcGIS REST services, as well as our standard APIs.

  • [The Place Names Gazetteer](http://www.linz.govt.nz/placenames/find-names/nz-gazetteer-official-names/nzgb-gazetteer) contains **official** and **unofficial** place names under the jurisdiction of the New Zealand Geographic Board Ngā Pou Taunaha o Aotearoa (NZGB). Official place names are those that have been assigned, altered, adopted, approved, and validated under the NZGB Act 2008 or through other statutes that assign official names, for example, Treaty settlement legislation. Unofficial place names are those that have not been processed under the NZGB Act 2008 or through other relevant statutes. Data is extracted from Land Information New Zealand’s (LINZ) ‘New Zealand Gazetteer of Official Geographic Names’, which is maintained by the NZGB Secretariat. Geographical coverage encompasses New Zealand, the Ross Dependency of Antarctica, and the Continental Shelf of New Zealand. The NZGB has naming jurisdiction over: - natural features such as mountains, peaks, valleys, glens, forests, lagoons, swamps, creeks, streams, rivers, fords, lakes, glaciers or ice features, bays, islands or harbours (including man-made features of the same type) - railways or railway stations, but not railway features such as marshalling yards, transfer sites, or track point locations - places, i.e. cities, towns, villages, sites, areas, or similar places, including suburbs and localities - undersea features - Crown protected areas - Districts and regions (altering only if requested by the local authority) Each name is provided with a location represented by a point. More complex geometry (e.g lines for rivers or areas for suburbs) is not currently available. Each geographic feature has one or more place names associated with it. Place names usually comprise two components – ‘specific’, being for the proper noun, and ‘generic’, being a description of the geographic feature type. Information provided for each place name may include: name; name status (whether official or unofficial); geographic feature type; authority by which an official name became official; district within which the name is located; geographic location; reference information; history/origin/meaning; and additional notes. Not all information is available for all names. Positional accuracy is generally the same as 1:50K mapping. Information accuracy reflects information at the time of original capture.
