dfs file
You must prepare a data file containing an item with the zone numbers. For building zones, the file must also contain an item with height or level when "From file" is specified for the height format. For road zones the file must also contain an item with the offset when "From file" is specified for the offset format. The file must be a 2D unstructured data file (dfsu) or a 2D grid data file (dfs2). The area in the data file must cover the model area. For both a dfsu-file and a dfs2 file piecewise constant interpolation is used to map the data. The input data file must contain only a single time step.
xyz file
The data in the file must be formatted as ASCII text in five columns with the two first columns giving the x-and y-coordinates of the points. The third column represents connectivity. The connectivity column is used to define arcs. All points along an arc - except the last point - shall have a connectivity value of 1 and the last point shall have a connectivity value of 0. The fourth column contains the z-value at the point. Finally, the fifth column contains the zone number. The z-coordinates is only used when the xyz file is used to define building zones. Here the z-value must contain the height of the buildings or the level of the top of the buildings.
You must select the map projection (Long/Lat, UTM-32, etc.) in which you want to specify the horizontal location of the points.
shape file
The shape file format is a geospatial vector data format for geographic information system (GIS) software. To use a shape file to define zones, the shape type must be either Polygon, PolygonZ or PolygonM. The zone numbers must be written as a field in the dbf-file. The zone numbers must be integers larger than 0 for each polygon. If the height or level of buildings are specified from file they must also be written as a field in the dbf-file. Any empty record value of a field will be read as 0. This means that all zone-values must be given and any building with an empty height or level record will have that height or level set to 0.
In the shape file selector you specify the map projection in which the data is given when you click on “Conversion”. If a .prj file is included in the shape file data, the projection is obtained from this file. If there is no .prj file available you need to specify the map projection.
