File Import ECW

ECW - (Enhanced Compression Wavelet)is a proprietary wavelet compression image format which are georeferenced and optimised for aerial and satellite imagery. The image can be updated as the viewer zooms in to effectively display a higher LOD (Level of detail).

Draping over a surface - Once imported, a raster image conversion can be exported, or draped onto a surface. This image is a standard type of bitmap and doesn't have the same LOD capability as the original ECW file - i.e. when zooming in, the image can't increase detail

1. On the Labs ribbon tab navigate to the Import group and select Import ECW.

2. Select whether to import a file or download a file from a URL. The image is saved in the images container.

3. Click OK to finish.

Draping an ECW image over a surface

1. Tile and tie image window and surface window

2. Drag ECW image onto surface. A panel will open titled Export image.

3. Adjust settings accordingly - whether to scale the image and / or crop the image.

4. Click OK or Apply to finish.

Note: The draped image is a plain bitmap - it is no longer capable of increasing definition when zooming in.

Tile and tie windows then drag image onto surface.
