BLM OR Chemical Treatments Polygon

Frequently-asked questions:


What does this data set describe?

Title:
BLM OR Chemical Treatments Polygon

Abstract:
CHEM_POLY: This dataset represents completed chemical land treatments on BLM managed lands in the states of Oregon and Washington. Chemical treatments are applications of herbicide or pesticide, to control or kill pests and invasive plants, or fertilizer to enhance plant growth.

Supplemental information:
Treatments are human alterations to the landscape for the purpose of natural resource management, including use, enhancement, and protection. A treatment creates something new; it creates a new physical entity on the landscape. This distinguishes treatments from attributes or information about treatments. Treatments are areas (polygons), zones of alteration. Chemical treatments have complex reporting requirements. Thus, additional attributes are necessary such as chemical application, quantity, active pounds applied, and target species for each chemical in the mix

    Calendar date: 20141020
    Currentness reference:
    ground condition

  5. What is the general form of this data set?

    Geospatial data presentation form: vector digital data

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):
      • GT-polygon composed of chains (5302)

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 2e-008. Longitudes are given to the nearest 2e-008. Latitude and longitude values are specified in Decimal Degrees.

      The horizontal datum used is D North American 1983.
      The ellipsoid used is GRS 1980.
      The semi-major axis of the ellipsoid used is 6378137.0.
      The flattening of the ellipsoid used is 1/298.257222101.

  7. How does the data set describe geographic features?

    OSODBA.CHEM_POLY_new
    OBJECTID
    Internal feature number. (Source: ESRI)
                      

    Sequential unique whole numbers that are automatically generated.

    SHAPE
    Feature geometry. (Source: ESRI)
                      

    Coordinates defining the features.

    TRT_ID
    Unique number identifier for the treatment entity.  Multiple "units" of a treatment are given unique TRT_IDs and TRT_ID is unique across all treatment feature classes.  Multiple units or phases of a treatment project are tied together by TRT_NAME, PLANID, NFPORS_PROJID or CONTRACTID as applicable. (Source: BLM)
                      

    TRT_NAME
    Free text name that identifies the treatment entity, preferably with a place reference and treatment type reference.  The name is one-to-one with TRT_ID and the two together provide more reliable identification as long as neither is changed.  Naming conventions need to be standardized by programs and/or offices and enforced in order to avoid confusion and loss of information. (Source: BLM)
                      

    PROJ_NAME
    District-assigned name for a project that encompasses several treatment types and/or treatment units.  It is not the same as the plan or project authorizing the action (PLANID) and there may be many PROJ_NAME for one PLANID. (Source: BLM)

The OR/WA BLM may have administrative responsibility over some area that is physically located in Nevada, Idaho, and California, and vice versa.  Similarly, the treatment may cross Resource Area or District boundaries and the administrative responsibility is assigned to one or the other.  The unit can be identified only to the district or even state level. (Source: BLM)

    TRT_ACRES
    These are actual acres treated or estimated acres proposed for treatment.  Not derived from GIS but can be set to GIS_ACRES, if the entire polygon is considered treated. The TRT_ACRES may be substantially less than the total polygon acres, particularly for CHEM_POLY where treated acres (TRT_ACRES) is calculated as total gallons applied (GAL_MIX_AP) divided by MIX_RATE.

    TRT_MONI

Was consumption of the targeted fuels inadequate, adequate, or excessive? 2.	Were targeted mortality levels inadequate, adequate, or excessive? 3.	Was soil heating acceptable or unacceptable? 4.	Did any unacceptable damage to non-targeted resources or  resource values occur?  For chemical treatment of weeds (CHEM) the question might be "Are there any weeds left?"  For exclosures (PROT), the question might be whether the targeted animals were effectively excluded.  For seedings (REVEG), the questions might include: 1.	What was the germination percentage? 2.	What percent survived 1 year? 3.	What was the coverage? (Source: BLM)

    ACCURACY_FT
    How close, in feet, the spatial GIS depiction is to the actual location on the ground.  There are several factors to consider in GIS error: scale and accuracy of map-based sources, accuracy of Global Positioning System (GPS) equipment, and the skill level of the data manipulators.  A value of "0" indicates no entry was made.  This is the correct value when the COORD_SRC is another GIS theme (Digital Line Graphs (DLG), Geographic Coordinate Database (GCD), Digital Elevation Model (DEM)) because the accuracy is determined by that theme.  However, if COORD_SRC is MAP (digitized from a paper map) or GPS, a value of "0" indicates a missing value that should be filled in either with a non-zero number or "-1."  A value of "-1" indicates that the accuracy is unknown and no reliable estimate can be made. (Source: BLM)

Why was the data set created?

This dataset is used for district, state, and regional needs for management and query of land management treatment.

How was the data set created?

  1. Where did the data come from?

  2. What changes have been made?

    Date: unknown (change 1 of 2)
    Legacy data may be introduced to the dataset by manuscripting on maps and digitizing, GPS, on-screen digitizing using a DOQ or DRG backdrop, duplicating lines from ownership, roads or stream layers, or a combination of these. Treatment boundaries that are based on identifiable physical features such as roads, ridgelines, streams, or on ownership changes should utilize those source line features to illustrate the cartographic relationship. New treatment polygons and edits of existing polygons will be added and noted by district staff.

    Date: 20120209 (change 2 of 2)
    Compared the Pesticide Application Reports with the CHEM feature class. Added 52 new treatments across the district ranging from SWAT, BLM, Contract, and MMS sites. Made corrections, deleted duplicates, and modified some polygons.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Many features were imported from the legacy data and the attributes are very incomplete. However, newer features will have more complete information and over time the dataset will become more accurate.

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    Treatments are dynamic themes that are subject to frequent edits and changes.

  5. How consistent are the relationships among the observations, including topology?
