‘Spatial Manager’ includes an option to manage the Z coordinate when importing spatial data (Shapefiles, Google Earth KML, ASCII, Excel, LiDAR, etc.) into AutoCAD, BricsCAD or ZWCAD drawings. It is a configuration little known by many of the application users... more
LiDAR (Light Detection And Ranging) is a surveying method that measures distance to a target by illuminating the target with pulsed laser light and measuring the reflected pulses with a sensor. Differences in laser return times and wavelengths can then... more
A set of objects imported by applying its coordinate Z=0 leads to a “flat” map which allows us often to perform operations that are more “uncomfortable” when using 3D maps: 2D references, measurements of distances in the plane, etc. ... more
When reading Shapefiles (SHP) which include terrain Contour lines, it is very common to find that the Z coordinate of each Contour is set as being a numerical data in a Field of the associated data table Object Elevations... more
Some 2D Shapefiles (SHP) may include 3D information inside its associated alphanumeric data table. For example, it is quite common to find the values of the elevation and height of the polygon features inside some fields of the data table 3D and pseudo-3D Shapefiles... more
The KML or KMZ files of Google Earth can include some little-known parameters which apply to the Features they contain. One of these parameters is the Altitude of the Features By using the Altitude parameter, the Features can be placed... more
