Description:
Abstract:
A spatial tiling index designed for storage of file-based image and other raster (i.e., LiDAR elevation, landcover) data sets.
Purpose:
This index is primarily a data processing, data storage level index which allows all raster and image data stored at this level to be maintained in a common, consistent tile and naming scheme. It is based on the original IDXP7500 layer, but has been extended to cover a signficantly larger area than just King County. Where it overlaps the original IDXP7500 grid, the two grids are identical.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The attributes from the original IDXP7500 were conflated to the new grid. Where new attributes were required, they were calculated in. All attributes were evaluated to ensure sequentiality and uniqueness.
Logical_Consistency_Report:
The grid defines cells with an alpha column identifier cocantenated with an integer row identifier. Because the grid was extended south and west of the original origin (AA01), a reverse progression of the column identifer was applied going west. Going south of the original origin, a decreasing integer sequence is applied. So although from the new origin, the progression of column and row identifiers is not linearly continuous, each cell is uniquely identified and there are no duplicates.
Completeness_Report:
The grid is complete for the extent of its bounds. No areas are omitted.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: The vertices of each cell corner are accurate to 1 foot.

Process_Step:
Process_Description:
The fishnet tool was used to create the grid so that it aligned with the original IDXP7500 grid. Where coincident the attributes were populated with a spatial join. New attributes were added for those cells outside of the original grid. Due to the naming convention, the extension to the west generated two columns that were duplicative of existing columns to the east of the original origin. These two western-most columns were delete to ensure uniqueness. This did not significantly affect the useable extent of the grid.
