* Only objects that have a certain attribute can be exported by checking the ''With Attribute'' option and selecting the desired attribute. For example if you only want [[Culvert_(Water_Overlay)|culverts]], you can select the category ''Underground'' (since the function culverts belongs to the category Underground) and check the ''With Attribute'' option and select the attribute name ''CULVERT_DIAMETER'' for example. This will export culverts, since only these objects have this attribute in common.

Vector data

The objects that make up the project area can be exported as 2D vector data in different formats/methods. In the Current Situation tab, each of the following menus has an export Geo data option:

With this data, further calculations or other analysis can be done in for example GIS software. See below for the steps.

How-to's

Raster data

Grid Overlays can be exported as raster data or as vector data. With the exported data, calculations from for example the Water overlay can be exported to be further processed for analysis in GIS software. See below for the export options for Grid Overlays.
