Line 57: ==Generate IDW Interpolation== Generate aan IDW (Inverse Distance Weighted) interpolation of the Z shape points layer (points layer containing elevation data), using the QGIS processing tool 'IDW Interpolation'. For more information about this tool, please refer to <u>[https://docs.qgis.org/3.3440/en/docs/user_manual/processing_algs/qgis/interpolation.html#qgisidwinterpolation QGIS Documentation - IDW Interpolation]</u>. <ol> <li> In QGIS, load all Z shape points layers within the polygon extent (e.g. '''TUFLOW\model\gis\2d_zsh_M02_landscape_002_P''').
