    Description

    This feature class displays the State data for the dataset that represents the GIS Version of the Public Land Survey System including both rectangular and non-rectangular surveys. The primary source for the data is cadastral survey records housed by the BLM supplemented with local records and geographic control coordinates from states, counties as well as other federal agencies such as the USGS and USFS. The data has been converted from source documents to digital form and transferred into a GIS format that is compliant with FGDC Cadastral Data Content Standards and Guidelines for publication. This data is optimized for data publication and sharing rather than for specific 'production' or operation and maintenance. This data set includes the following: PLSS Fully Intersected (all of the PLSS feature at the atomic or smallest polygon level), PLSS Townships, First Divisions and Second Divisions (the hierarchical break down of the PLSS Rectangular surveys), and the Bureau of Census 2015 Cartographic State Boundaries. The Entity-Attribute section of this metadata describes these components in greater detail.

    Please note that the data on this site, although published at regular intervals, may not be the most current PLSS data that is available from the BLM. Updates to the PLSS data at the BLM State Offices may have occurred since this data was published. To ensure users have the most current data, please contact the BLM PLSS Data Set Manager.

    Description

    This feature class depicts the boundaries of Land Survey features called sections, defined by the Public Lands Survey System Grid. Normally, 36 sections make up a township. The entire extent of each of these units should be collected, not just the portion on National Forest System lands. This dataset is derived from the USFS Southwestern Region ALP (Automated Lands Program) data Project. This is one of six layers derived from ALP for the purpose of supplying data layers for recourse GIS analysis and data needs within the Forest Service. The six layers are Surface Ownership, Administrative Forest Boundary, District Boundary, Townships, Sections, and Wilderness. There were some gapes in the ALP data so a small portion of this dataset comes from CCF (Cartographic Feature Files) datasets and the USFS Southwestern Region Core Data Project. ALP data is developed from data sources of differing accuracy, scales, and reliability. Where available it is developed from GCDB (Geographic Coordinate Data Base) data. GCDB data is maintained by the Bureau of Land Management in their State Offices. GCDB data is mostly corner data. Not all corners and not all boundaries are available in GCDB so ALP also utilizes many other data sources like CFF data to derive its boundaries. GCDB data is in a constant state of change because land corners are always getting resurveyed. The GCDB data used in this dataset represents a snapshot in time at the time the GCDB dataset was published by the BLM and may not reflect the most current GCDB dataset available. The Forest Service makes no expressed or implied warranty with respect to the character, function, or capabilities of these data. These data are intended to be used for planning and analyses purposes only and are not legally binding with regards to title or location of National Forest System lands.

This data defines a catchment for every stream segment containd within the Geofabric Surface Network product according to the GEODATA Nine Decond Digitial Elevation Model (DEM-9S) Version 3. These stream segment level boundaries may be used individually or in aggregation. The product is designed to represent geographic surface boundaries that have a hydrological relationship to surface water features. The NCB Level 1 and NCB Level 2 features are the top two levels in the NCB Catchment hierarchy and have been provided as polygon boundaries. This product contains one Geofabric feature type called Catchment. It also contains three NCB feature types including: NCBLevel1Drainage Division, NCBLevel2Drainage Basin and NCBPfafstetter. Purpose This product is intended to support the creation of or definition of topologically consistent and hydrologically enforced streamflow aggregation boundaries. The catchment attributes can be extending by linking the NCB Pfafstetter table to include the Pfafstetter reference system for identifying and aggregating catchments. This product is intended to supplement the Geofabric Surface Cartography and Geofabric Surface Network data products. This product is also used to as the basis for building contracted catchments in the Geofabric Hydrology Reporting Catchments product and provides a spatial framework for analysis and assessment of streams and their catchments. Dataset History Geofabric Surface Catchments is part of a suite of Geofabric products produced by the Australian Bureau of Meteorology. The geometry of this product is largely derived from the National Catchment Boundaries (NCB) V1.1.4. It consists of catchments, NCB Level 1 Drainage Divisions, NCB Level 2 Drainage Basins and the NCB Pfafstetter table. The feature class terminology for Geofabric Surface Catchment components has been modified to distinguish it in terms of the products underlying data model. The AHGFCatchments are based upon polygons converted from a regular 9 second grid delineating the NCBs for the Australian continent. The NCBs delineate hierarchically-nested catchments derived using an automated drainage analysis procedure based on a multi-flow extension of the version 3.1 flow direction grid associated with the 9 second DEM (GEODATA National 9 Second Digital Elevation Model (DEM-9S) Version 3, ANZLIC unique identifier: ANZCW0703011541). At the highest levels in the hierarchy the NCBs aggregate the 9 second drainage basins (9 second Basins product name and ANZLIC identifier to be inserted) into 12 topographically-defined Drainage Divisions (Level 1) and 191 Drainage Basins (Level 2) approximating the Australian Water Resources Council (AWRC) River Basins (Australia's River Basins, Geoscience Australia, 1997 ANZLIC identifier: ANZCW0703005427) where possible. At lower levels, the Level 2 units are sub-divided into successively finer sub-catchments using a modified version of the Pfafstetter procedure (Verdin, K. L. and Verdin, J. P. (1999) A topological system for delineation and codification of the Earth's river basins. Journal of Hydrology, 218(1-2), 1-12). This layer delineates the lowest level catchment units being the sub-catchments draining directly to a stream segment in the ANUDEM stream layer or, where there are no ANUDEM Derived Streams (ANUDEM Streams), the 9 second drainage basin. The higher level catchment membership of each of these sub-catchments is derived from its NCB code. Changes at v2.1 - SegnoLink updates. ! updates to NCB level 2 names to conform with HR_Regions. Changes at v2.1.1 ! Updates to NCB level 2 names to conform with HR_Regions. - SegnoLink attribute update to fix single catchment feature in Tasmania. - Correction to spelling of Numeralla river in AHGFCatchment (formerly Numaralla). - Correction of name for NCBLevel2DrainageBasinGroup, 'Moorabool River' Basin Group renamed to 'Little River'. - Fixed a series of NoFlow catchments (small internally draining catchments not related to a stream segment) in Murray-Darling were incorrectly attributed as externally draining via the ExtrnlBasn field in AHGFCatchments. - Fixed Basin attribute values in NCBPfafstetterm, which were incorrectly populated with BasinLevel field. Processing steps: ANUDEM v1.1.4 National Catchment Boundaries (NCBs) dataset is received and loaded into the Geofabric development GIS environment. feature classes from ANUDEM NCBs are recomposed into composited Geofabric Framework Dataset feature classes in the Geofabric Maintenance Geodatabase. re-composited feature classes in the Geofabric Maintenance Geodatabase Feature Dataset are assigned unique Hydro-IDs using ESRI ArcHydro for Surface Water (ArcHydro: 1.4.0.180 and ApFramework: 3.1.0.84) feature classes from the Geofabric Maintenance Geodatabase Feature Dataset are extracted and reassigned to the Geofabric Surface Catchment Feature Dataset within the Geofabric Surface Catchment Geodatabase. A complete set of data mappings, from input source data to Geofabric Products, is included in the Geofabric Product Guide, Appendices.

    Abstract

    This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

    This product, Australian Statistical Geography Standard (ASGS) Volume 1 - Main Structure and Greater Capital City Statistical Areas (cat no. 1270.0.55.001), is the first in a series of Volumes that will detail the various structures and regions of the ASGS. Its purpose is to outline the conceptual basis of the regions of the Main Structure and the Greater Capital City Statistical Areas and their relationship to each other.

    Volume 2 - Indigenous Structure (cat no. 1270.0.55.002), is the second in a series of Volumes that detail the various structures and regions of the ASGS. Its purpose is to outline the conceptual basis for the design of the Indigenous Structure. This product contains several elements including the manual, region names and codes and the digital boundaries.

    The Non-ABS Structures bring together those regions which are not defined by the ABS, but which are important to users of ABS statistics. ABS is committed to providing a range of statistics for these areas. They generally represent administrative regions and are approximated by Mesh Blocks (MBs), Statistical Areas Level 1 (SA1) or Statistical Areas Level 2 (SA2). As the Non-ABS Structures represent regions that are subject to ongoing change, the ABS will release a revised publication for ASGS Non-ABS Structures in July each year. The individual structures will only be updated where significant change has occurred in the past year.

    Full metadata is available at the feature class level by selecting the 'Description' tab in ArcCatalog.

    This dataset contains three Geodatabases:

A Bureau of Land Management (BLM) Administrative Unit is a geographic area in which an organizational unit of the BLM has distinct jurisdictional responsibility for land and resource management activities occurring on the public lands, the maintained rights of the United States (i.e. mineral estate) and actions relating to the Trust responsibilities of the U.S. Government as stipulated in Law or Treaty.The State Office is the top layer of the three-tier organization, with District Offices being the middle layer and providing coordination, oversight and support to the lowest level, the Field Office. Idaho has one State Office, four Districts and twelve Field Offices. This feature class documents the physical boundary of an administrative unit. In some cases, the administrative unit may manage areas outside of the boundary for other programs’ purposes - this datset does not show these areas. BLM Idaho administers a little land in Nevada also, which is included here. For more information contact us at blm_id_stateoffice@blm.gov.

    Description

    It has long been established that earthquake ground motions may be amplified by weak deposits such as soils and other unconsolidated sediments. Seismic microzonation aims to identify these amplification effects through the classification of subsoil classes or local ground shaking properties and appropriate engineering design.In New Zealand, the current building code NZ1170.5 (Standards New Zealand 2004) specifies discrete subsoil classes ranging from A (hard rock) to E (very soft sediment). This project has developed new subsoil class maps for the Wellington City Territorial Authority area managed by the Wellington City Council.The maps were generated from new geological mapping available for the area, an updated borehole database, a database of site period measurements and a 3D geological model constructed for this study.The updated maps use the 2004 NZS1170.5 standard subsoil classification.The area mapped in this study extends from Tawa southwards, encapsulating Johnsonville, Newlands, Khandallah, Wilton, Karori, Ngauranga, Horokiwi, Thorndon, Te Aro, Newtown, Island Bay, Kilbirnie, Miramar and Seatoun. These areas all have accumulations of looseto dense Quaternary sediment deposited on indurated and variably weathered Rakaiaterrane basement rock. The sediment in these areas varies in thickness from a few metres to several hundred metres.The soft sediments are prone to amplification of ground motion during earthquakes, particularly where significant thicknesses are preserved.The subsoil classifications mapped in Wellington City are NZS1170.5: B, C, D and E.To create the boundaries and subsoil class maps, a 3D geological model has been constructed,drawing on databases of site period measurements and borehole data. In total, 931 site period measurements from previous studies are compiled in the database, with some reprocessed for this study. Records from 2422 boreholes are also compiled into another database from sources such as the New Zealand Geotechnical Database (NZGD), GNS Science and private records available to GNS Science for research purposes. A 3D geological model was created from these data and from existing geological mapping to model the sub-surface geometry of11 geological units and create depth to basement and thickness maps. All of these data were utilised to create a map of the subsoil classification in Wellington City and improve on previous studies through the integration of new data compiled and advanced modelling techniques.Several areas around Wellington are data-poor and lack borehole information or geophysical measurements to constrain the subsoil classes and their boundaries. We recommend that additional data is collected in important zones, such as those in Kilbirnie and Miramar where subsoil classes D and E are modelled, allowing their extent to be better determined.

    Description

    The National Hydrography Dataset Plus (NHDplus) maps the lakes, ponds, streams, rivers and other surface waters of the United States. Created by the US EPA Office of Water and the US Geological Survey, the NHDPlus provides mean annual and monthly flow estimates for rivers and streams. Additional attributes provide connections between features facilitating complicated analyses. For more information on the NHDPlus dataset see the NHDPlus v2 User Guide.Dataset SummaryPhenomenon Mapped: Surface waters and related features of the United States and associated territories not including Alaska.Coordinate System: Web Mercator Auxiliary Sphere Extent: The United States not including Alaska, Puerto Rico, Guam, US Virgin Islands, Marshall Islands, Northern Marianas Islands, Palau, Federated States of Micronesia, and American Samoa Visible Scale: Visible at all scales but layer draws best at scales larger than 1:1,000,000Number of Features: 3,035,617 flowlines, 473,936 waterbodies, 16,658 sinksSource: EPA and USGSPublication Date: March 13, 2019Prior to publication, the NHDPlus network and non-network flowline feature classes were combined into a single flowline layer. Similarly, the NHDPlus Area and Waterbody feature classes were merged under a single schema.Attribute fields were added to the flowline and waterbody layers to simplify symbology and enhance the layer's pop-ups. Fields added include Pop-up Title, Pop-up Subtitle, On or Off Network (flowlines only), Esri Symbology (waterbodies only), and Feature Code Description. All other attributes are from the original NHDPlus dataset. No data values -9999 and -9998 were converted to Null values for many of the flowline fields.What can you do with this Feature Layer?Feature layers work throughout the ArcGIS system. Generally your work flow with feature layers will begin in ArcGIS Online or ArcGIS Pro. Below are just a few of the things you can do with a feature service in Online and Pro.ArcGIS OnlineAdd this layer to a map in the map viewer. The layer is limited to scales of approximately 1:1,000,000 or larger but a vector tile layer created from the same data can be used at smaller scales to produce a webmap that displays across the full range of scales. The layer or a map containing it can be used in an application. Change the layer’s transparency and set its visibility rangeOpen the layer’s attribute table and make selections. Selections made in the map or table are reflected in the other. Center on selection allows you to zoom to features selected in the map or table and show selected records allows you to view the selected records in the table.Apply filters. For example you can set a filter to show larger streams and rivers using the mean annual flow attribute or the stream order attribute. Change the layer’s style and symbologyAdd labels and set their propertiesCustomize the pop-upUse as an input to the ArcGIS Online analysis tools. This layer works well as a reference layer with the trace downstream and watershed tools. The buffer tool can be used to draw protective boundaries around streams and the extract data tool can be used to create copies of portions of the data.ArcGIS ProAdd this layer to a 2d or 3d map. Use as an input to geoprocessing. For example, copy features allows you to select then export portions of the data to a new feature class. Change the symbology and the attribute field used to symbolize the dataOpen table and make interactive selections with the mapModify the pop-upsApply Definition Queries to create sub-sets of the layerThis layer is part of the ArcGIS Living Atlas of the World that provides an easy way to explore the landscape layers and many other beautiful and authoritative maps on hundreds of topics.

    Description

    This polygon feature class shows the spatial extent and boundaries of Areas of Critical Environmental Concern that have become officially designated by the BLM. These polygon features were previously in a pre-designated status (i.e. being considered as areas to be eventually designated as official ACEC designated polygons). Once these polygon feature left the Pre-Designated phase (transitioned from a Considered to Designated status), they were removed from the ACEC Pre-designated polygon feature class and placed in this ACEC Designated polygon feature class. This dataset is a subset of the official national dataset, containing features and attributes intended for public release and has been optimized for online map service performance. The Implementation Guide represents the official national dataset from which this dataset was derived.
