- Abstract:
-
The Tidelands claims line depicts natural waterways now or formerly tide-flowed at mean high water. Since the mean high water line may change because of rises in sea level, the line does not represent the current mean high water line. Rather it depicts the mean high water line at the time of mapping and the historic mean high water line predating artificial alterations. Note: Users of this combined statewide tidelands layer are cautioned that this layer is to be used as a reference layer only. Only the actual promulgated tidelands maps, at the production scale of 1:2400, can be used to locate the legally valid tidelands riparian claim line.
- Purpose:
-
The data was generated to be utilized in a GIS to show the Tidelands claims line which depicts natural waterways now or formerly tide-flowed at mean high water.
- Supplemental_Information:
-
Users of this combined statewide tidelands layer are cautioned that this layer is to be used as a reference layer only. Only the actual promulgated tidelands maps, at the production scale of 1:2400, can be used to locate the legally valid tidelands riparian claim line.

- Process_Description:

To create this statewide tidelands layer, the following additional processing steps were undertaken: The riparian claims lines were first selected from each individual tidelands map and appended together using the ARCINFO APPEND command. A polygon layer was created from this appended layer by using the CLEAN command with the polygon option. This was done so that areas claimed under the riparian law could be easily identified in the composite layer. Once cleaned, an attribute, STATUS, was added to the .pat of the coverage. All areas being claimed under the riparian law, i.e. all areas mapped as being now or formerly flowed at below mean high water in each of the individual tidelands maps, could then be identified, and given the STATUS value of 'CLAIMED'. All other polygon areas were given a STATUS value of 'UNCLAIMED' to indicate that these areas were not flowed at or below mean high water, and are not part of the NJ riparian claim. Once all of the polygons in the appended riparian coverage were evaluated and attributed, the grid with all of the individual tidelands map boundaries and map identifiers was joined with the polygon claim coverage using the ARCINFO UNION command (JOIN option; .01 fuzzy tolerance). This coverage was checked to insure that all areas within the tidelands grid boundaries were properly attributed with the correct STATUS value. Following this check, the layer was converted to a shapefile for posting and distribution. Users of this combined statewide tidelands layer are cautioned that this layer is to be used as a reference layer only. Only the actual promulgated tidelands maps, at the production scale of 1:2400, can be used to locate the legally valid tidelands riparian claim line.

This layer was initially created as a composite of the individual tidelands maps at 1:2400 scale and the riparian claims lines. The topological errors from the tidelands grid layer were introduced into this dataset when the composite was made. Since the claimed and unclaimed areas broken up into grids, it was not possible to get an accurate measure of the area symbolizing data was cumbersome.
To update the statewide tidelands layer, the following processing steps were performed:
The dissolve geoprocessing tool was used to aggregate the claimed and unclaimed features into a single polygon. This successfully removed a majority of grid outlines. The integrate geoprocessing tool was used to initially fix the integrity of the feature boundaries due to gaps or overlapping features. Setting a small xy tolerance of 0.005 helped make feature boundaries coincident while preserving the original shape. The dissolve geoprocessing tool was used again to aggregate the claimed and unclaimed features into a single polygon. The remaining area's that were affected by the topological errors of the grid itself were manually modified by hand. In order to perform the manual changes, the topologically affected areas had to be clipped out and stored in a temporary polygon feature class. The corresponding clipped area was erased from the primary set. In order to fix the topological errors in the temporary feature class, additional vertices were added or existing vertices were removed to make boundaries coincident. Once all changes were made to the temporary feature class, it was appended back into the primary feature class and dissolved to aggreate claimed and unclaimed features.
Dissolving the features based on claim status introduced additional errors due to the max number of vertices that can be stored in a single feature. Features with too many vertices are automatically split into multiple parts. This was resolved by breaking the claimed and unclaimed areas into regions. The regions are based on the tidelands regions map which can be found here: https://www.state.nj.us/dep/gis/digidownload/images/tidelands/tide_regions.gif. The regions feature class was created using the topologically fixed tidelands grid layer and dissolving grids based on region name. The union geoprocessing tool was used to compute the geometric union of the regions layer and tidelands area. The dissolve tool was run an additional time to dissolve features based on region and status.
The layer was checked to insure that all topological errors were removed. The integrity of the claimed boundary was checked against the original layer to ensure that no major changes were made to the boundary shape.
