Pricing
from $3.85 / 1,000 results
Screens coordinates against BLM Section 368 West-wide Energy Corridors using BLM current designations plus the Argonne mirror. Returns corridor name, width, permitted use, whether a later plan amendment deleted it, distance to the nearest corridor and a ROW streamlining signal.

Asset label
asset_label
Optional
Label of the screened site (as provided, or 'lat,lon').
Asset latitude
asset_lat
Optional
Latitude of the screened site (WGS84).
Asset longitude
asset_lon
Optional
Longitude of the screened site (WGS84).
Search radius (mi)
radius_miles
Optional
Radius in miles used for this asset (per-asset override or global default).
In corridor
in_corridor
Optional
True when the point falls inside a designated Section 368 energy corridor polygon in the BLM current layer. Null when that layer did not answer - never a confident false in that case.
Corridors within radius
corridor_count_within_radius
Optional
Distinct BLM current corridors whose boundary lies within the search radius, including any the point is inside. Null when the primary source did not answer.
Nearest corridor ID
nearest_corridor_id
Optional
Source FID of the nearest (or containing) corridor polygon.
Nearest corridor name
nearest_corridor_name
Optional
Corridor segment identifier from the Argonne dataset (a route-segment code, e.g. '78-138', not a place name).
Designated use (raw)
nearest_designated_use
Optional
Raw DesigUse code from the source: e.g. 'Electric-only', 'All' (multi-modal), 'Pipeline'.
Designated use (label)
nearest_designated_use_label
Optional
Plain-English label for the designated use.
Width (feet)
nearest_width_feet
Optional
Designated corridor width in feet. Null when the source published the -1 sentinel rather than a real width; nearest_width_feet_is_unpublished flags that case.
Managing agency
nearest_managing_agency
Optional
Federal agency managing this corridor segment (BLM or USFS).
Section 368 status (raw)
nearest_sec368_status
Optional
Raw free-text Sec368Stat field from the source, e.g. 'Designated'.
Formally designated
nearest_sec368_designated
Optional
True when the nearest corridor is currently a designated Section 368 corridor, false when a later land-use plan amendment deleted it or statute prohibits its designation, and null when the published status text is outside the recognised vocabulary.
Nearest distance (mi)
nearest_distance_miles
Optional
Distance in miles to the nearest corridor polygon boundary within the radius; 0 when the site is inside a corridor.
ROW streamlining flag
row_streamlining_flag
Optional
True only when the point is inside a corridor that is currently designated. False when it is outside a corridor or the corridor was deleted or prohibited. Null when the corridor status is unrecognised or the primary source did not answer.
ROW streamlining note
row_streamlining_note
Optional
Plain-language routing signal. Reports the nearest corridor and its distance when the point is outside one, says explicitly when a corridor has been deleted, and reads NO DETERMINATION when a source did not answer.
Error
error
Optional
Error message for an unparseable coordinate or a per-asset failure; null otherwise. Per-source failures are reported in the *_source_status and sources_failed columns.
Disclaimer
disclaimer
Optional
Informational-use disclaimer, including which corridor dataset is primary and its vintage.
Checked at
checked_at
Optional
ISO 8601 UTC timestamp of the screening run.
Source URL
source_url
Optional
The Argonne mirror service URL, retained for continuity. See source_urls for both services.
Primary source
primary_source
Optional
Which corridor dataset produced the primary in_corridor answer. BLM Section 368 Designated Corridor - Current, the dataset BLM itself maintains.
Source URLs
source_urls
Optional
Both corridor services queried, keyed by source name.
BLM layer last updated
blm_current_layer_last_updated
Optional
Date the BLM current corridor layer was last edited, read live from the service metadata on every run rather than hard-coded.
Argonne layer last updated
argonne_layer_last_updated
Optional
Date the Argonne mirror was last edited, read live on every run. The previous version of this actor documented 2017-12-12; the service reports 2020-11-30.
Corridor source
corridor_source
Optional
Which dataset produced the corridor hit for this row. Null when the point is not inside a corridor.
Status category
nearest_sec368_status_category
Optional
Normalised category of the nearest corridor published status: designated, designated_width_addition, designated_added_later, designated_use_restricted, deleted, prohibited, or unknown.
Status label
nearest_sec368_status_label
Optional
Plain-language meaning of the status category, including whether a later land-use plan amendment deleted the corridor or restricted its permitted use.
Status recognised
nearest_sec368_status_recognised
Optional
False when the published status text is outside the vocabulary this actor decodes. The designation answer is then null rather than a guess.
Deleted or prohibited
nearest_corridor_deleted_or_prohibited
Optional
True when the nearest corridor was deleted by a later land-use plan amendment or its designation is prohibited by statute - it is NOT an available Section 368 corridor. Null when the status text is unrecognised.
Width unpublished
nearest_width_feet_is_unpublished
Optional
True when the source published the -1 sentinel instead of a real corridor width, in which case nearest_width_feet is null rather than a negative number.
Locally designated
nearest_locally_designated
Optional
Whether a locally designated alternative corridor exists for the nearest corridor, as published.
Corridor comments
nearest_corridor_comments
Optional
Free-text comment published on the nearest corridor polygon, which sometimes records a locally adjusted width or status.
In corridor (BLM current)
in_corridor_blm_current
Optional
Point-in-polygon result against the BLM current corridor layer - the primary answer. Null when that layer did not respond.
In corridor (Argonne mirror)
in_corridor_argonne
Optional
Point-in-polygon result against the Argonne 2020 mirror, reported for continuity with earlier runs of this actor. Null when that layer did not respond.
Sources disagree
corridor_alignment_disagreement
Optional
True when the BLM current layer and the Argonne 2020 mirror disagree about whether the point is inside a corridor. Both alignments are real and both are reported; the BLM current answer governs.
Corridors in radius (BLM current)
corridor_count_within_radius_blm_current
Optional
Distinct BLM current corridors within the search radius.
Corridors in radius (Argonne)
corridor_count_within_radius_argonne
Optional
Distinct Argonne mirror corridors within the search radius.
BLM source status
blm_current_source_status
Optional
Outcome of the BLM current corridor query: ok, unavailable, or not_applicable.
BLM source error
blm_current_source_error
Optional
Error message when the BLM current corridor query did not answer; null on success.
Argonne source status
argonne_source_status
Optional
Outcome of the Argonne mirror query: ok, unavailable, or not_applicable.
Argonne source error
argonne_source_error
Optional
Error message when the Argonne mirror query did not answer; null on success.
Sources that failed
sources_failed
Optional
Names of the corridor sources that did not answer for this asset. Null when both answered.
Partial result
partial_result
Optional
True when at least one corridor source did not answer for this asset, so the row is not a complete screen.
