 If you are familiar with QGIS or GIS software in general as well as ENVI-met, the plugin will be easy to use. Simply follow the prerequisites on the Welcome page of the plugin. If you are familiar with QGIS or GIS software in general as well as ENVI-met, the plugin will be easy to use.

-The sub area layer should be a polygon layer featuring a single rectangular polygon. This rectangular polygon is then used as the border for the ENVI-met model area.+The sub area layer should be a polygon layer featuring a single rectangular polygon. This rectangular polygon is then used as the border for the ENVI-met model area. Please note, that the edge between the first and second vertex of the polygon defines the lower x-axis of the ENVI-met model area.
  
 After selecting the sub area layer, the user can set the horizontal resolution of the model area. The resulting number of grids is calculated on the fly. Typical horizontal resolutions range from 2 meters to 10 meters. Please note that smaller number of grids will result in a faster microclimate simulation. After selecting the sub area layer, the user can set the horizontal resolution of the model area.

 ===== Additional Gridding settings ===== ===== Additional Gridding settings =====
 +In the "[Additional Gridding settings]", further adjustments to the resulting model area can be made.
  
 +== Default Roof / Wall Material ==
 +Here, the user can define, which roof / wall materials shall be used for buildings. This field is only been read, if a building wall / roof material was not defined earlier in the Geodata section.
  
 +== Clear building cells close to the model border ==
 +The lateral boundaries of the model area should be clear of structures roughly half the height of the adjacent buildings. This option will clear the lateral border cells from buildings. The user can define the number of cells that should be cleared from buildings
  
-  * Lateral boundary should be clear of structures roughly half the height of the adjacent buildings (see Additional Gridding options)+== Use leveled building heights for buildings in DEM == 
 +Since roof heights of buildings are defined based on the local ground level, buildings, that are placed on a slope, or any kind of changing terrain level might show altering roof heights, that follow the terrain. This option ensures a level roof even when using DEM, by interpreting the building height from the lowest terrain height underneath a building.
  
 +== Start gridding of surfaces with ==
 +This option might save considerable time of the digitization process. By defining a start surface type, first all surfaces are gridded with that ENVI_ID. Only areas where more information about the surface type is available from the "[Surfaces]" tab, are then altered. This can save time, since one surface type does not have to be digitized at all and is simply taken as the surface type if nothing else is defined.
  
 +== Remove vegetation from Buildings ==
 +This option will remove all vegetation that might end up on top of building due to gridding. In case you want to use roof top greening, please consider the fields in the "[Buildings]" tab, or disable this option
