Monde World Editor

The program Monde is the ENVI-met Suite world editor allowing you to digitize your model area vector based before exporting it to a raster based *.INX file.

World Setup

As a first step, similar to most other programs of the ENVI-met Suite, you should select the project you are working in (1). Before creating a new map in Monde, you will need to setup your geographic location. You can do this via the World Setup button (2) in the MyWorld Tab. Here, you can assign a name to your map and define a location in UTM coordinates. This is important if you e.g. load OSM data into your map and for the simulations later on. When importing shapefiles which already have a geographic reference, you do not need this step.

Obtaining Area Data

There are different ways of obtaining area data for this program. You can digitize your area in the program itself, import OpenData, or import Shapefiles.

Digitizing in Monde

In order to create your own modeling layers in Monde, you can simply add a modelling layer in the Layers tab. Here, you can choose the type of modelling layer you would like to digitize (1). These types coincide with the ENVI-met layers buildings, simple and 3D vegetation, surface, point, line, or area source, and receptor.

If you e.g. decide to create a building layer, the layer will appear as a modelling layer on the left-hand side (1). With the respective layer selected, you can start editing the layer (2) and digitize your building (3).

For a detailed overview on how to digitize in Monde, please watch our first Monde Expert Lesson.

Importing OpenData

The option to import area information from open data sources might be a convenient way of obtaining data for your simulation. Please find some further information about this data type in our OpenData Overview. Monde currently allows the download of OpenStreetMap (1) and OpenTopography (2) data .

Importing Shapefiles

If you already have shapefiles (*.SHP) of your model area, you can simply import those by using the “Import from Shape File” option in the Add GIS Layer option of the Layers tab. This will open a new dialogue where you can load the shapefile you would like to import. Before adding the layer to your map, you can define some import options and the coordinate system/UTM zone.

Export Data to ENVI-met Format

Before you can run your simulation with the model area information from Monde, you will need to convert them to the ENVI-met format. There are two steps that, depending on your layer information. If the layer already contains the information needed for the ENVI-met layers (e.g. your building layer already contains the height information or the surface layer already contains the ENVI-met Surface ID), you can directly export it to a modelling layer. If such information is not yet included in the layer, you will need to classify the attributes first.

Classify Attribute

If you right-click on e.g. a GIS layer and choose “Classify Attribute…”, the below dialogue will open up. Here, you can choose source attribute you would like to use to assign the ENVI-met attribute to. You also need to define what type of attribute it it (e.g. surface) and can give your layer a name (1). You can then move the attributes you would like to define from your Attribute List to the list of Attribute Classification Rules on the left-hand side (2). Here, you can open a view of all materials included in the database (3) and assign the respective material (4). When you have repeated this with all attributes, you can click “Classify Attribute” and the allocation will be saved.

Export to Modelling Layer

In order to export the layer with your classified attributes to an ENVI-met Modelling Layer, you can again right-click on the layer and choose “Export to Modelling Layer…”. Here, you need to once again declare the modelling layer type and can assign the values using the attribute data you just created. Once you repeated those steps with all your layers, you can then create a ENVI-met model area.
