1. What is an ESRI world file?
A world file is a plain text file containing information about the geographic reference of an image or a map. With this information, a ZKI map can be imported into a geographic information sytem (GIS).
2. What is a KMZ file and how do I open it?
A KMZ file is a compressed collection of files which allow for the visualization of a ZKI map with the Software ‘Google Earth’. If you have installed Google Earth on your computer, you can open the file by clicking on the link “KMZ file for Google Earth”. Alternatively, you can download the file first (right mouse button -> “Save target as…”) and open it in Google Earth afterwards.
3. Why is the high resolution map not displayed in the web browser?
Some Browsers have problems with displaying very large images like the high resolution versions of our ZKI maps. In this case, please download the image file first (right mouse button - “Save target as…”) and open it with an image processing or visualization software on your computer.
4. Can I get the satellite imagery?
Unfortunately, we can’t provide you with the original satellite imagery used in our maps due to licensing issues.
5. May I use the map products of ZKI in a presentation or a publication?
