Louisiana Administrative Code › Title 43 - NATURAL RESOURCES › Part XXVII - State Lands › Subpart 1 - Land Information Mapping and Map Records System › Chapter 9 - Photo Laboratory Procedures › Section XXVII-905 - Photo Index

Current through Register Vol. 50, No. 6, June 20, 2024
A. The contractor
				  shall prepare a photo index for each scale and coloration (i.e., black and
				  white or color) of aerial photography flown by stapling together the contact
				  prints (or reduced size prints), trimmed to the image area. The prints shall be
				  carefully matched so that the corresponding images overlap and all photo
				  numbers are visible. This original composite of contact prints shall be
				  photographically copied, reduced in scale, and reproduced in uniform size
				  sheets not to exceed 42 inches high by 42 inches wide. The reduction of the
				  photo index scale may be to any appropriate size, but in no case smaller than
				  four times the scale of the contact print or 1" = 1 mile, whichever is the
				  larger scale. The index shall contain the names of prominent geographic
				  features for orientation purposes. Each index shall also include title
				  information identifying the project, date and scale of the project, name of the
				  contractor, date and scale of the aerial photography, type of camera and focal
				  length of its lens, the scale of the photo indexes, and a north arrow. In the
				  event two or more photo indexes are required at any one scale, a diagram will
				  be drawn in each photo index's margin. Photo indexes shall be oriented to the
				  north, and the title information should appear in the south or east margin of
				  each index. A photo index negative, three mylar-based screen positives and
				  three photographic double weight semi-matte paper copies will be required for
				  each scale of aerial photography.

A. Aerial
				  triangulation shall be performed in a Local Space Rectangular System based on
				  the Geodetic Reference System 1980 (GRS 80) ellipsoid. Geoid separation from
				  the ellipsoid shall be established for each project area and referenced to NAD
				  83 for photogrammetric purposes. The Local Space Rectangular System shall be
				  configured as secant at its origin and shall have a negative ellipsoid height
				  at origin as established for the specific project area.
B. Elevations shall be referenced to the
				  National Geodetic Vertical Datum of 1929, or subsequent NAVD 88 datum, as
				  applicable, and shall be assumed to be in perfect coincidence with the
				  ellipsoid surface (no geoid slope). The input and output coordinate systems
				  shall be in geodetic coordinates (NAD 83) of Latitude, Longitude and
				  Orthometric Height to ensure proper utilization of the Local Space Rectangular
				  (LSR) System for the aerial triangulation computational solution. Separate
				  transformations shall then be performed on the triangulated positions to index
				  elevations back to NGVD 1929 or NAVD 88 datum and to express horizontal
				  coordinates in the Louisiana State Plane Coordinate System, NAD 83, North or
				  South Zone, as applicable.
C. For
				  each aerial triangulation block solution performed, the contractor shall take
				  extraordinary care to record and preserve the LSR system origin used for the
				  solution. Variance-covariance matrices should be referenced to the LSR system
				  for both camera stations and triangulated ground points if supplied with the
				  aerial triangulation report. However, an error propagation of the bundle
				  adjustment will not be required. The responsible contracting authority may
				  perform an error analysis independently to validate the contractor's
				  work.

Current through Register Vol. 50, No. 6, June 20, 2024
A. Passpoint
				  locations will be manually selected by reviewing the control photographs in
				  stereo. Selected passpoints shall be located, symbolized and labeled on the
				  image side of the control photographs. All selected locations will lie on
				  unobscured level ground whenever topographic conditions permit. Particular care
				  shall be taken in selection of passpoints so that in built-up urban areas (and
				  rural when possible), points shall be selected that are field recoverable.
				  Field recoverable points are defined as discrete intersections of linear
				  features such as two sidewalks, sidewalks and curbs, slab corners (parking
				  lots, driveways, etc.), and discrete point features such as manholes, storm
				  drain gratings and other small manmade features.
B. For analytical aerial triangulation,
				  individual frames will carry a minimum of nine passpoints, with the exception
				  of end frames of flight lines which will carry a minimum of six passpoints. One
				  point will lie in the corner of each neat model, and one point will lie near
				  each nadir position of each neat model. It is recognized that deviation from
				  the ideal distribution may be necessary for those photographs covering bodies
				  of water and/or areas of heavy ground cover. Tie points between strips will
				  occur with a frequency of at least one per frame. As a general rule, wing
				  passpoints within lines of flight will also serve as tie points between

Louisiana Administrative Code › Title 43 - NATURAL RESOURCES › Part XXVII - State Lands › Subpart 1 - Land Information Mapping and Map Records System › Chapter 13 - Digital Mapping Requirements › Section XXVII-1301 - General Requirements

Current through Register Vol. 50, No. 6, June 20, 2024
A. The
				  purpose of this Section is to establish guidelines and requirements for
				  computerized digital mapping in accordance with these standards. These
				  guidelines and requirements provide descriptions of terminology, data
				  structure, accuracy and data exchange specifications.
B. In order to capture information for use in
				  a digital mapping system, it is necessary to store X and Y Louisiana State
				  Plane Coordinates (North or South Zone), including applicable vertical
				  coordinate data, for every point that is used to define the graphic aspects of
				  the map. Thus, a road would be represented in digital format by a number of
				  points (X and Y coordinate pairs) that define its location. The digital mapping
				  system would then be able to depict the road by plotting straight or curved
				  lines between the points. The process of capturing the coordinate points and
				  storing them in a computer or computer-readable format is called digitizing.
				  Digitization may be accomplished by the use of coordinate geometry, by using
				  electronic tables that record coordinate points, by manually tracing over
				  source map information, or by using automatic scanning (digitizing)
				  devices.
C. The digitization of
				  planimetric and topographic base maps shall be accomplished by digital
				  stereo-compilation of controlled aerial photography. The digitization of parcel
				  ownership maps will be based upon existing map sources and record information
				  combined with cartographic features derived from planimetric and topographic
				  base map imagery.

B. Map Grid
				  System. The map grid system established by these standards is based on a 1" =
				  400' basic regional map which is designated the "Basic Modular Unit." The Basic
				  Modular Unit concept provides for a series of maps corresponding to each
				  respective area classification at four separate scales which are defined as
				  follows.
1. 1" = 400'. The boundaries of each
				  Basic Modular Unit shall be the grid lines of the Louisiana State Plane
				  Coordinate System (North or South Zone) evenly divisible by 10,000 feet in
				  north-south and east-west directions.
2. 1" = 200'. Each map shall be one quarter
				  of a Basic Modular Unit (see §1517. B.1 and accompanying §1529,
				  Appendix B). The neat image area of this map unit shall be bounded by the
				  Louisiana State Plane Coordinate System (North or South Zone) grid lines, with
				  values of easting and northing evenly divisible by 5,000 feet.
3. 1" = 100'. Each map shall be one sixteenth
				  of a Basic Modular Unit (see §1517. B.1 and §1529, Appendix B). The
				  neat image area of this map unit shall be bounded by the Louisiana State Plane
				  Coordinate System (North and South Zone) grid lines with values of easting and
				  northing evenly divisible by 2,500 feet.
4. 1" = 50'. Each map shall be one
				  sixty-fourth of a Basic Modular Unit (see §1517. B.1 and §1529,
				  Appendix B). The neat image area of this map unit shall be bounded by the
				  Louisiana State Plane Coordinate System (North or South Zone) grid lines with
				  values of easting and northing evenly divisible by 1,250 feet. The orientation
				  of all maps will be such that the north boundary of any map sheet is parallel
				  with the top border of each sheet.

Current through Register Vol. 50, No. 6, June 20, 2024
A. In order to
				  verify base map compilation and facilitate subsequent parcel map preparation,
				  rectified vertical aerial photographic negative and positive photo atlas sheets
				  shall be produced for each scale of planimetric or topographic base maps to be
				  developed. Photo atlas sheets will be positioned so that each 1" = 50', 1" =
				  100', 1" = 200' or 1" = 400' base map plot will have a corresponding photo
				  atlas sheet of the same scale, size and orientation as the companion base map.
				  The total sheet size will be 28 inches high by 30 inches wide and will be
				  printed within the same border area as the companion base map imagery. The
				  photo image area of each sheet will be 25 inches by 25 inches and will extend
				  past the edges of the base map plots by 1 inch, which results in a 2-inch
				  overlap between adjacent photo atlas sheets. All photo atlas sheets will be
				  properly rectified so that the edge match between the base map plot and the
				  corresponding photo atlas sheet will be within 1 percent of the total sheet
				  distance (i.e., the match borders will not be off by more that 0.25 inches). A
				  typical photo atlas sheet layout is included within §1535, Appendix
				  E.
B. All rectified aerial photo
				  atlas sheets shall be made directly from the aerial photography negatives. The
				  rectified positives shall have fine grain quality and uniform density, shall
				  preserve the clarity and detail of the original negatives to the maximum extent
				  possible, and shall be free of dust, marks, scratches, fog, streaks, stains and
				  blemishes of any kind. The photo atlas sheets may be screened or unscreened at
				  the discretion of the responsible contracting authority.
C. One set of photo atlas sheets shall be
				  provided on dimensionally stable double-matted 4 mil film material formatted to
				  each companion base map sheet. All sheets will be printed with the right
				  reading side opposite the emulsion side. Each sheet shall have grid ticks which
				  appear as 1/2 inch (0.50") long black intersecting lines on the final imagery
				  at 5-inch intervals.
