Getting Started

You can search IGS GeoLab using two methods. You can zoom into an area and click a site to bring up additional information. Or, you can search the database using the tools provided on the right. Details of each tool's function are found below.
IGS GeoLab does not allow all sites to display on the original, full-scale map. More samples may appear as you zoom in.

Missing samples

You may notice patches or gaps where samples should be. The closer you zoom in the more samples will appear in the area. If you still don't see your sample please report it.
