BLM OR Culverts Point Hub

공공데이터포털

CULVERTS_PUB_PT: This dataset defines attributes for major and minor culvert structures. According to BLM Manual 9100, a culvert is “a conduit or passageway, not classified as a bridge, under a road, trail, or other facility usually consisting of a round pipe, a pipe-arch, or an open or closed bottom box or arch.” Major culverts are defined as “a culvert having a clear opening of more than 35 square feet or multiple installations of culverts placed adjacent or contiguous as units and having a combined clear opening of more than 35 square feet.” This dataset only reflects the most current condition of the culvert as of the last visit and does not track the history of the culvert over time. Historic (removed) features may be retained in the parent Structures dataset.

The purpose of this dataset is to provide structural culvert locations along highways . The definition of a Structural Culvert is a culvert with span of 2 metres or greater. Drainage culverts have a diameter less than 2 metres and are not included in this dataset. Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

STRCT_ARC: Structures are discrete, physically existing things that are built. Structures are things created to support treatment, recreation or other management activities. STRCT_ARC contains, but is not limited to, features such as pipelines, fences, and trails.

BLM OR Wild and Scenic River Corridor Polygon Hub

공공데이터포털

wsrcorr_poly: This layer is the polygon representation of the Wild and Scenic River Corridors on BLM managed lands within Oregon. The National Wild and Scenic Rivers System was created by Congress in 1968 to preserve certain rivers with outstanding natural, cultural, and recreational values in a free-flowing condition.

BLM OR Cadastral PLSS Standardized Data PLSS Point Hub

공공데이터포털

PLSSPOINT: PLSS Point data created by the Bureau of Land Management for the states of Oregon and Washington. This feature class is part of the Cadastral National Spatial Data Infrastructure (NSDI) CADNSDI publication data set for rectangular and non-rectangular Public Land Survey System (PLSS) data set. The metadata description in the Cadastral Reference System Feature Data Set more fully describes the entire data set (http://www.nationalcad.org/). These are the corners of the PLSS. This feature class contains summary information about the coordinate location and reliability of corner coordinate information. alternate names or aliases for corners are also included in this feature class.

BLM OR Water Quality and Quantity Cross Section Sample Publication Point Hub

공공데이터포털

CROSS_SECT_SAMPLE_PUB_PT: Cross-sectional surveys capture the shape of the stream channel at a specific location by measuring elevations at intervals across the channel. Cross-sections are used to determine bankfull width, mean bankfull depth, and entrenchment of a channel at a specific point. Cross-sections are usually installed and monitored to track geomorphic change in a stream before and after a physical alteration to the channel; these surveys can detect erosion and deposition of stream sediment as well as changes to the shape (profile) of stream bed and banks. The cross-section table defined in this data standard stores the summary measurements. Raw data can be stored in a spreadsheet or document and related to the record.

BLM OR Wild and Scenic Rivers Line Hub

공공데이터포털

wsr_arc: This layer is the line representation of the designated Wild and Scenic River segments under BLM management within the boundaries of Oregon and Washington. The National Wild and Scenic Rivers System was created by Congress in 1968 to preserve certain rivers with outstanding natural, cultural, and recreational values in a free-flowing condition.

BLM OR Water Quality and Quantity Stream Discharge Sample Publication Point Hub

공공데이터포털

DISCHARGE_SAMPLE_PUB_PT: Sample points recording stream discharge. Stream discharge is the volume of water passing a location per unit of time, and is generally expressed as cubic feet per second (cfs). The discharge table defined in this data standard stores the summary measurements. Raw data can be stored in a spreadsheet or document and related to the record.
