The Esri Shapefile or simply a shapefile is a popular geospatial vector data format for geographic information systems software. It is developed and regulated by Esri as a (mostly) open specification for data interoperability among Esri and other software products. Shapefiles spatially describe geometries: points, polylines, and polygons. These, for example, could represent water wells, rivers, and lakes, respectively. Each item may also have attributes that describe the items, such as the name or temperature.
In Erdas virtual gis it is possible to extrude buildings when using 3d shape files. We create the 3D shapefile in Arc Gis basing the elevations off the surface we use in the visualization. We then add individual building hieghts to the shape file which will put the foot print in its correct elevation on the surface. This extrusion process will extrude the buildings into 3D. This process then includes all positive extrusions as a height field, extruding from the roof downwards.

Development of the OLI-2 and TIRS-2 instruments is progressing, and both are on target for integration with the spacecraft in mid-2019. The instruments are rebuilds of those onboard Landsat 8; however, TIRS-2 has improved stray light performance through improved telescope baffling and improved position encoder for the scene select mechanism, both issues on the Landsat 8 TIRS instrument. The Landsat 9 ground system and Mission Operations Center (MOC) are progressing through their respective milestones. Landsat 9 remains on schedule for a December 2020 launch from Vandenberg Air Force Base..

EarthOnDrive will be presenting its latest technologies and mapping software at the GeoBusiness, U.K. on May 22-23, 2018. The GEO Business show has grown every year since its inception, and the 2018 show looks set to be the most successful show to date with more exhibition space and a brand new seminar program. The event will return to the Business Design Centre, in London, UK, May 22-23.
Since its record-breaking 2017 event last year, which welcomed 2,386 geomatics and geospatial professionals from around the world (a 48 percent increase since the launch in 2014), the exhibition has expand..
Developers of the first real-time ray-tracing and global illumination Texturing Solution based on wavelet theory, WavGen Pro allows computer graphics users working with Maya 2017/18 and 3D Studio Max 2017/18 3D the abilithy to model, render, and animate literally terabytes of imagery and thousands of hypershade nodes. WavGen announces new and updated plugins for Linux, OSX, and Windows, that further integrate wavelet technologies with Autodesk’s line of 3D modeling, rendering, and runtime applications. We now have exporter plugins for work flows in gaming (Unity, Scene Graph, Unreal, Cry..
