The OpenStreetMap function of MithraSIG allows to download data from internet on a specified area, and convert them automatically into MithraSIG objects. So, no need to use the process integration/convertion of data.

Warning: OSM data is open source and is not the property of Geomod. Geomod cannot be held liable of the data. It remains to the user to verify the data used for his project.

Import data

Before to use the automatic integration, it's necessary to add a backdrop, then zoom in on the area to import. The maximum extents allowed is one fifth of a degree in longitude and latitude. Note that the OpenStreetMap server may also impose other load-based limits. When the area is too large, a message appears.

To import, from the ribbon Model, click on the button in the group Integration. Then in the drop down menu, select OSM Integration. The import window appears.

The window is composed of:

•Extend: X,Y coordinates min and max of the area. Coordinates are linked to the current projection.

•Items to import: select the type of items to import and integrate in MithraSIG.

•Add vertices at DTM intersections: option highly recommanded when using 2D data. For more details, read this chapter.

•Reset: check this option to reset the project and perform a new integration.
