Abstract:
Texas landcover grid created from counties landcover coverages. The steps used to create the grids are as follows: 1. The projection system of Input Counties Landcover Line Coverage was changed from Geographic to Albers. 2. The polygon coverage was build using Build command in Arc prompt. 3. Then the grid was made using Polygrid command in Grid. An AML program was used to create the merged grid. grid: Tempgrid2 = merge(andrew, tempgrid1) This work was divided in two parts, i.e. all the grids starting from a to m were merged to make "am" and the remaining grid as "nz". Then "am" and "nz" were merged to make the grid "az". grid: az = merge(am, nz) 4. The output grid "az" has the null values at the intersection of their boundaries. To fill those null value the following statement was used: grid: az_foc66 = con(isnull(az), focalmajority(az, rectangle, 6, 6, data), az) The final output grid "az_foc66" renamed to "TxLandcover" still contains few null valued cell, but within the acceptable range.
Purpose: Texas landcover grid
