In some cases it is useful to simulate swept paths on other sources than Google Maps satellite pictures. In HeavyGoods you have two options to upload plans from other sources:
Upload CAD plans in DXF format
Upload drone pictures, satellite pictures from other data bases in common image formats (JPG, PNG).
To upload a CAD file (DXF) just go to your simulation view and drag & drop it onto the map:
The CAD plan is scaled automatically. You can choose between the units 'mm' and 'm' if the scaling does not fit. Once the plan is uploaded it appears on the map and you now need to position it correctly:
To get a better visualization of the CAD plan, change the oppacity of the Google Maps satellite picture here:
Once you're done you can do simulations just as you are used to!
You want to export the calculated swept path? No problem, just click here:
Notice:
Currently HeavyGoods only supports CAD files in DXF format. To use a DWG file or other format, first convert it to DXF.
Make sure that the unit of measurement of your plan is millimeters (mm) or meters (m).
CAD files should contain only relevant data:
Road markings of the actual narrow section
Building outlines in the immediate area of the narrow section
Delete drawing elements (e.g. legends, frame lines) that are outside of the narrow section area.
Delete layers with 3D information. If you use a 3D device for scanning the road clearance profile (e.g. a 3D laser scanner), use your 3D software to extract the 2D polygon outlines. Remove any point clouds of your 3D measurements from the CAD.
Delete any further layers that are not relevant for the trafficability analysis.
Delete any embedded raster / bitmap images (such as screenshots, photos or logos) or irrelevant CAD layouts / viewport views.
