Version 2.0

• In some cases, tiles were not correctly completed using subprocess calls to the GDAL executables. Replaced the subprocess calls with the GDAL API.
• Updated the tile output to remove overlapping areas.
• Simplified the output structure.
• Updated the terrain multiplier algorithm as per AS/NZS 1170.2 (2011) and recent amendments.
• Updated the topographic multiplier algorithm to include the Tasmania factor as per AS/NZS 1170.2 (2011).
• Updated the topographic multiplier algorithm to remove the conservatism associated with the topographic multiplier as described in this Record, with a modification to the treatment of shallow topographic features such as shallow hills and escarpments. In the case where Mt < 1.4, a linear interpolation is constructed so that the percentage of reduction is gradually increased from 0 at point (Mt = 1) to 10 at point (Mt = 1.4))
• Updated the shielding multiplier convolution mask to exclude the grid point being evaluated.
