Lidar Survey Ancient Maya City

Scene Viewer showing 3D city model overlaid on DTMPage 16-19: The ancient Maya site of Copan, Honduras, has been captured during an airborne Lidar survey in May 2013. The resulting products are accessible through 2D and 3D WebGIS tools and enable archaeologists to collaborate online.

Crowdsourcing Reconstruction

Interview: Arnulf Christl, president emeritus OSGeo

Arnulf ChristlPage 12-15: Title: Open Geospatial Source Deserves Open Geospatial Minds. At FOSS4G, the annual global event of the Open Source Geospatial Foundation (OSGeo), GIM International met with Arnulf Christl, president emeritus of OSGeo and geospatial systems architect, to discuss the role of the open source community within the geomatics world, the outlook for the long run and the opportunities open source offers to less developed countries.

Technology in Focus

The port of Rotterdam, The NetherlandsPage 24-25: Title: Low-power Wide-area Networks: Enabling geo-IoT.The true potential of IoT has started to unfold beyond the interest of pioneers in the last couple of years. One of the reasons IoT is now booming is the emergence of more low-power wide-area networks. this article explains the concept of LPWANs and the link to geographic information.

Mobile Road Mapping
