Export Point Results (TXT/SHP) and Batch export point results (SHP) now include the Item ID field.– EXPORTED_H: indicates which height is exported, relative or absolute. – GRND_VALID: indicates whether the item’s ground level values are valid / calculated Additional fields when exporting items to Shape.Open model dialogue: Improved layout and direct edit option for area/version/model descriptions by clicking twice on the description.

In case of a larger model a separate menu-item ‘3D full model’ is available.
By default the 3D view shows the current 2D model view with a maximum of 10x10km. 3D View now uses the display settings of items. Increased usability and user experience. Improved performance generating noise contours. Items outside this concave poygon will get the default terrain height that is given in the calcuation settings. The terrain model is now calculated within a concave polygon around the entered height lines and height points. Memory usage has been reduced up to a factor of 2 and speed has been increased up to a factor of 100. Increased performance of terrain model calculation for large noise mapping models. A specific property/field of a selected number of items can now be modified by using a numeric or textual expression that can use other properties/fields of the same item. This allows the user to enable or disable the showing of backgrounds, results and/or contours and to start a calcuation with a single click. Additionally several new countries and local coordinate systems have been added for the African, Asian, Australasian, European, North American, Central American/Caribbian and South American continents. This option fully replaces the Georeference tool. Background Maps can now be calibrated/georeferenced with 2 known global GPS coordinates and sellecting the local coordinate and reference system.

(only for Pro and Enterprise configurations) The highest point on the rotor is calculated by taking the turbine height and adding half of the rotor diameter. For this purpose an additional property ‘Rotor diameter’ has been added to the Wind turbine item. This option limits the topographic screening effects of the terrain to a reduction of no more then 2 dB and then only if there is no direct line of sight between the highest point on the turbine rotor and the calcuation point.

Wind turbine screening limit option according to IOA-GPG in calculation settings for ISO 9613.1/2 and ISO 9613.1/2 (1/3 Octave) models. Changes in iNoise 2021 compared to iNoise 2020 New and improved functionality
