Process description:
The State of Washington's aquatic land ownership records have been maintained on marine index maps or index plates.  These are hand drafted maps some of which are over 100 years old.  They are vulnerable to decay and there has been a lot of interest in having the agency's aquatic ownership incorporated into DNR's GIS.  The initial step was to have over 4000 of the index plates scanned and vectorized into ARC coverages.  One step in incorporating these coverages into the agency's GIS is to transform them into state plane feet (south zone 5626, Nad27). Control points on each individual index plate must be established, using meander corners, PLSS section corners and other points.  These control points are added to the vector coverages and empty coverages created with a stateplane south BND, as tic-ids.  Using ARC/INFO transformation a matching coverage in state plane feet is created (T_covers).  Arcs from the T_covers are selected and put into an Aquatic land parcel coverage.  The arcs and polygons are coded with desired attributes.

The first step in this process was to have all of the index maps scanned.  The scanned tif images were then digitized into ARC/INFO vector coverages.  The scanning and digitizing processes were performed by contractors.  The vector coverages are in digitizer inches with no coordinate system and need to be georeferenced into state plane coordinates to match DNR's other GIS data sets.  For each vector coverage there need to be a minimum of four control points established with known state plane coordinates.  With these control points it is possible using an ARC/INFO process to transform the vector coverages into coverages with state plane coordinates.  These vectors or lines can then be used to build polygons or areas which represent every parcel of aquatic land.  Each vector is individually coded and needs to be carefully assembled to create a coverage with no gaps or seams.  Each polygon or area is then coded with up to 32 attributes, converting all of the needed information from the index maps into a GIS data set.  These coverages are refereed to as landparcel coverages.  When a geographic area is completed the work is reviewed by the aquatic surveyor.  The finished coverage is then given to the aquatic computer programmer who runs the coverage through some error checking programs and prepares the coverage for conversion into the agency's cadastral framework project.

INPUTS

Vector coverages of marine index plates, plats and harbor areas.
Three types:
1.  Second class tide and shore lands plates, the originals.
2.  Digitized second class tide and shore land plates.
3.  First class plates.

Tif images of the marine index plates, plats and harbor areas.

POCA (Public Ownership and County Administration coverage) coverage provided in a township tiling format which provides section lines.

PLS-PT also in township tiling format, contains the section corner and quarter quarter points.  This is where the meander corners should be added to.

GLO plats.

NAMING CONVENTION FOR COVERAGES

The vector covers for the indexes, plats and harbor area plats are numbered with three parts.  The first part, two letters, the first of which, is a "t" or an "s", means tideland or shoreland and the second letter, an "f" or an "s", means first or second class.  After the two letters there are two numbers which identify the county.  This is followed by a dash and a three digit unique number for that type of land in that county.  The format is for example ts29-032, and would be read as tidelands, second class in Skagit county, plate 032.  The empty coverages that the vector coverages are transformed into carry the same name with a "T" suffix (the T_covers).  So.....tf25-014 would be tf25-014t.  The tif images also use the same naming convention with the .tif extension.

QUALITY CONTROL ON VECTOR COVERAGES

Produce an edit check plot of the vector coverage overlayed on the tif image.  Identify and highlight any missing arcs from the vector coverage that are necessary.  Necessary arcs include meander lines, platted tidelands, lease lines and deed lines.  Upland lot lines and PLSS lines are not needed. In arcedit digitize any of the missing arcs.  Edit tolerances for vector coverages:

editdistance 15.0
nodesnap off 2.0
weedtolerance .05
grain .05
arcsnap off
snapping off 2.0
intersectarcs off

CONTROL POINTS

Control points with known locations must be established for each vector coverage.  A minimum of six control points are needed.  The control points are identified and marked on check plots, and added as tic IDs in the vector coverages.  Matching tic IDs are added to the empty T_covers. There are three types of index maps and each requires different processes.  The three types are: second class plates, digitized second class plates and first class platted areas.  Meander corners are the highest priority control point and every meander corner available should be used as a control point.  Other control points will be described later.

ADDING MEANDER CORNERS TO EXISTING STATE PLANE TOWNSHIP COVERAGES

Meander corners were originally set by the General Land Office (GLO) during the surveying process of the PLSS township and range grid system.  A township is divided into 36 one square mile sections.  When  a water body was encountered along the one mile section line a meander corner was set and the distance was recorded from the section corner or the last meander corner, and recorded on the GLO plat for that township.  The recording distance is in chains and one chain equals 66 feet (80 chains equals one mile).  DNR has two coverages that are needed to add meander corners so they can be used for control points.  Once the meander corners are in an existing DNR coverage that coverage can be drawn up in arcedit as a back cover and tic IDs can be added at the meander corner locations.

CURRENT PROCESS FOR BUILDING MEANDER CORNERS

1.  Plot out township edit check plot with the arcs from POCA and the points    from PLS-PT.

2.  Mark approximate meander corner location on the check plot and record the distance in chains (and feet is optional).

3.  Edit work done in COGO in ARCTOOLS. Go into ARC and ARCTOOLS and open the township workspace and the POCA cover with arc as the editfeature. Set the draw environment to include arc, arrows and nodes.  Set tolerances. Select COGO and open the PLS-PT cover for the same township.  Select the COGO Environment button and within this menu select COGO POINT ITEM and move the cursor to select Point.id and make the next number to be 2000.  By selecting an arc and breaking the arc at the specified distance a point will be    generated in the PLS-PT coverage with a Point.id beginning with 2000.  Any number greater than 100 can be used, 2000 works well because it is 4 digits long and shows up well in arcedit next to other point values.

Edit tolerances:

Fuzzy    = 1.0  feet
Dangle   = 20.0  feet
Edit     = 100.0   feet
Nodesnap = 20.0   feet
Weed     = 1.0  feet
Snap     = 20.0   feet
Grain    = 1.0  feet

4.  Point.id is the type of point in PLS-PT.  The types are:

1 = Coordinate
2 = USGS projected
3 = USGS found
4 = Meander corner
7 = Pin Corner
10 = Closing North
11 = Closing East
12 = Closing South
13 = Closing West
14 = Protracted
99 = Stable

If a meander corner is within .25 chains (16.5 feet) of another point do  not add an additional point.  If the Point.id is greater that 10, change  that Point.id to be 4.  If the existing Point.id is less than 10 do nothing, this
Point.id value takes priority over a meander corner, but remember to  include this as a point for the statewide meander corner coverage and use it as a control point.

5.  Draw up the PLS-PT cover as a back cover with a symbol of POINT.ID. Redraw the screen.

6.  Determine if a proportion is needed on the line.  Find the total distance for the section line from the GLO notes,  compare this distance to the total distance on the POCA cover.  If the difference is greater than 15    feet then proportion the meander corner distances by dividing the Poca distance by the GLO distance and multiply this result by the meander corner distances.  If the section line is not a complete line in either    the POCA coverage or the GLO plats then a comparison can not be made and no proportion can be made.

7.  Select the arc to break and break at the distance or the proportion    distance and a point will be generated in PLS-PT.

8.  If the meander corner needs to extend further than the POCA line, then with the traverse option build an extension on the line.  Use two points along the line as the backsight point and extend the line 180 degrees with the necessary footage. This will also establish a point at the end of the line.

9.  Save the work.  Exit and select the PLS-PT as the edit cover and select all the Point.id's greater than 1999 and calc them to equal 4.  Select these as well as any of the  original points that had a Point.id less than 10 that will be used as meander corners and put the into the statewide meander corner coverage (STATEMC).

In a few cases the distance across a small stream was not recorded on the plat. Check the index plates and see if there is a distance recorded, and use that distance, if not and the distance is less than 200 feet then measure the distance from the index plate and use that to set the meander corner.  If the distance is greater than 200 feet contact DNR staff. There will be meander corners that can not be set.  The majority of these will be on peninsulas and islands, where the meander corners have no recorded distance from any section corners, only a distance between the meander corners. When this situation is encountered note on both the township edit check plot and the index check plot that the meander corners were not set.  Highlight the locations of the meander corners and the notes.

ESTABLISHING CONTROL POINTS FOR SECOND CLASS INDEX PLATES, ORIGINALS

The original second class plates are scanned and vectorized from linen paper maps (plates) that usually cover 4-8 sections.  On the majority of these there are enough meander corners to use for control.  If there are more than six, use them.  In arcedit delete existing tics and add tic IDs in the vector coverage at the meander corner locations using the tif image as a back image. Matching tic IDS can be added at meander corner locations in the empty T_covers using the STATEMC coverage or PLS-PT coverages as backcovers.  Zoom in very close to add tics or snap them to the backcover features to assure the most accurate position.  This accuracy is important in the transformation process which will be described latter.

ESTABLISHING CONTROL POINTS FOR SECOND CLASS INDEX PLATES, DIGITIZED

For some counties the originals were digitized on mylar.  The majority of the plates cover one section, so usually do not have enough meander corners to provide control.  They do have four tics that have state plane coordinates. With the four tic locations and two or more meander corners there are enough points.  Add tic IDs at the tic locations and meander corners locations.  The meander corners can be added to the T_covers as described above.  The coordinates for the four tic locations can be generated as tics in the T_covers. The coordinates for the digitized maps are zone appropriate so some of them are in state plane north zone and they will have to be projected to south zone first and then generated as tics.

ESTABLISHING CONTROL POINTS FOR FIRST CLASS INDEX PLATES, PLATS AND HARBOR AREAS

The basic process is the same as the original second class plates and if there are at least six available meaner corners then the process is the same. If there are not six meander corners then PLSS corners can be used.  If PLSS corners are used the matching tic IDs can be added in the T_covers from the POCA coverages.

If the minimum number of control points can not be met with meander corners and PLSS corners another approach is necessary.  First class plates are of a large scale and some cover only a part of a section which is why finding six control points is difficult.  The solution is to transform the plat for the area.  The plat is of a smaller scale and there will be plenty of control points.  Once the plat is transformed into state plane feet, then any easily identifiable point on the plat that is also on the plate can be used as control points.  Begin first with any meander corners and PLSS corners and then use angle points on the meander line or the harbor line, and last use block or lot corners.  Identify these control points on the edit check plot and then add them as tic IDs to the vector coverage and then the matching tic IDs to the T_covers. Harbor area plats can also be used like the plats to provide control for the index plates.

SUBDIVISION INSETS ON INDEX PLATES

Some of the index plates have subdivision inset that are a different scale than the index.  A separate vector coverage will have to be made with the subdivision lines, and then control points for it will have to be established.  The minimum of six will be difficult to obtain.  Three or four control points will be acceptable, and some of these will lack precision. It may be necessary to place control points at measured distances from known points, such as 150 feet east of the section corner, or 80 feet north and 40 feet west of the meander corner.  The idea here is to get these lines as close as possible and then adjust them to fit the rest of the index plate.  Name the new coverages the same as the index plate number followed by an underscore (_)and the letter "A" for the first one, letter "B' and so on.  If there are more than one insets begin letter "A" in the northwest corner and proceed with the remaining insets in a clockwise direction (with north at the top), around to the southwest.

TRANSFORMATION PROCESS AND RMS ERROR ACCEPTABILITY

In Arc, transform the vector coverages to the T_covers.  Note the RMS error for the output and record this value on the edit check plot of the index.  Desired RMS is 40 feet or less for all areas except second class shorelands (index maps that begin with the letters "ss") where 80 feet is the acceptable limit.

An example:

Arc: transform tf25-032 tf25-032t
Transforming coordinates for coverage tf25-032

Scale (X,Y) = (79.123,81.385)  Skew (degrees) = (-3.419)
Rotation (degrees) = (-139.841)  Translation = (1174995.241,506081.030)
RMS Error (input, output) = (0.138,11.265)

Affine  X = Ax + By + C
Y = Dx + Ey + F
A =          -60.471   B =           56.202   C =      1174995.241
D =          -51.028   E =          -59.064   F =       506081.030

1173114.722       505462.820           -9.166           -0.433

On this transformation the output RMS error is 11.265 feet.

If the RMS output error is greater than 40 first look at the x and y error for each individual tic id.  If the error is large (over 100 feet)it may indicate that Tic-id in either the vector coverage or the T_cover was located in the wrong place, i.e. along the wrong section line.  Occasionally a meander corner location is bad and it may be best to not use the corner for control.  Remove that Tic-id from one of the coverages and rerun the transform process.  If attempts to improve the RMS error fail notify DNR staff about the problem before going to the next step. We are aware that some coverages will have an RMS error greater than 40 feet.

ADJUSTING THE COVERAGES

After the transform process, go into arcedit and set up links to fine tune the positions of the arcs.  Set links to the meander corners, control points, PLSS lines and corners.  Run an adjust.  Save the coverage and build it with the line option.

The original definition use while building the aquatic ownership data was any parcel boundary line that is coincident with the shoreline as mapped in the DNR GIS coverage 'WTRLVLN' or 'Hydro'.  A better definition is that shoreline in marine areas is coincident with "mean high tide" and along non-tidal rivers and lakes is coincident with either the "line of vegitation" or the "line of ordinary high Water."

Enumerated domain value definition:
Estimated Tidal Extent Line.  The line which defines the limit of the area of tidal influence in a river, where this line has been estimated for purposes of the GIS.  For the aquatic boundary dataset, the type of aquatic index plate determined the upstream limit of tidal influence. The transition from a tideland index plat (TF or TS) to a shorelands index plat (SF or SS) was used as a guide to place an estimated tidal extent line. On a rare occasion, an Army Corp of Engineers report provided and indication in river miles how far upstream a river would be tidally influenced.

Enumerated domain value definition:
3 mile State/Federal Line.  Article 24 of the Constitution of the State of Washington defines the Pacific Ocean Boundary to be "one marine league off shore."  The ACSM Definitions of Surveying Terms defines a marine league a "a measure of distance commonly employed at sea, being equal to one-twentieth part of a degree of latitude, or three geographical or nautical miles."  The same book, in the definition of a nautical mile says that "because of various lengths on the nautical mile in use throughout the world, due to differences in definition and the assumed size and shape of the earth, the International Hydrographic Bureau in 1929 proposed a standard length of 1,852 meters, which is known as the international nautical mile.  The U.S. Departments of Defense and Commerce adopted this value in July 1, 1954."  Adopting this definition of a nautical mile the U.S. Department of Interior Minerals Management Service has calculated the State of Washington Pacific Ocean boundary to be 5556 meters seaward of the most westerly points of land along the coast and from the most westerly point of any islands within one marine league of the coast.  These most westerly points are referred to as "salient points."  The DNR has adopted the U.S. Minerals Management calculated boundary for purposes of the GIS.

Mean River Level.  A tidal datum.  The average height of the surface of a tidal river at any point for all stages of the tide observed over the National Tidal Datum Epoch.  It is usually determined from hourly height readings.  In rivers subject to occasional freshets, the river level may undergo wide variations and, for practical purposes, certain months of the year may be excluded in the determination of the tidal datum.  For charting purposes, tidal datums for rivers are usually based on observations during selected periods when the river is at or near a low water stage.

12 Mile Territorial Line.  On December 27,1988, U.S. President Ronald Reagan signed proclamation 5928, which claimed a 12 mile territorial sea for the U.S. As established by the United Nations Convention on the Law of the Sea (UNCLOS), the territorial sea is a belt of ocean which is measured seaward from the baseline of the coastal nation and subject to its sovereignty. This sovereignty also extends to the airspace above and to the seabed and subsoil. It is exercised subject to UNCLOS and other rules of international law relating to innocent passage, transit passage, archipelagic sea lanes passage and protection of the marine environment.
