Importing JPG/JGW Files into Bentley MicroStation V8i (SELECTseries 3)
These instructions apply to Bentley® MicroStation® V8i (SELECTseries 3) and describe how to load JPG and JGW files exported from Nearmap without losing the georeferencing information.
- Upon opening Microstation, create a new drawing by clicking the New tool.
- Choose a filename to create.
- Select your file and click Open to open the newly-created file.
- Click File -> Raster Manager.
- In the Raster Manager window, click File -> Attach -> Raster.
- Select the JPG file of interest and click Open. The Raster Attachment Options window should appear.
- Under Geometry, change Geo Priority to Sister File and click Attach.
- The image should now appear as a raster in Raster Manager. Right-click the raster and choose Coordinate System -> Select From Library.
- In the Select Geographic Coordinate System window, click the Search tab.
- Enter the map projection the saved image was downloaded in (if you did not choose this during download, it is likely 3857) and click Find Now.
- Select the appropriate map projection and click Ok.
- Click the Fit View button to adjust the View window to the boundaries of your image.
- At this point, you are done if the image was already in your desired map projection.
If you instead want to work with the image using a different, more local projection, first click Tools -> Geographic -> Select Geographic Coordinate System. Note this is different from changing the coordinate system used to interpret the loaded image; there is a coordinate system for the import, and a different coordinate system for how the rasters are projected onto your drawing space.
- Click the From Library button.
- Search for and select the projection you prefer.
- Click Ok. You are now working with Nearmap imagery in the projection you selected. Upon clicking Fit again, you should see a reprojected version of your image.
- The currently active projection should appear in the Geographic Coordinate System window. A useful way to check whether your images are displaying in an appropriate projection is to find a circular object on the ground (a roundabout, for example) and verify that it appears as a perfect circle.
