A Note about BIM and GIS Coordinates
A Note about BIM and GIS Coordinates
The ONUMA|System is unique because it uses the local 2D coordinate systems of BIM and the polar coordinates of Geographic Information Systems (GIS).
Due to the complexities of transformations of polar coordinates as used in Google Earth to rectangular (2D Cartesian) coordinates as used in the ONUMA|System, SketchUp, or other CAD applications, the mapping of points becomes more inaccurate, the further the points are away from the origin (0,0) of the site. In addition, the distortions of the satellite and map images from Google and ESRI that are displayed in the ONUMA|System make the correctly placed site objects seem to be even more displaced. The tolerance for these inaccuracies depends largely on what needs to be accomplished.
An area of 5,000 by 5,000 feet with the origin in the center shows discrepancies of approximately 5 feet towards the edge. In an urban context, this is usually about the limit but in a rural environment, this might not be of much concern. Some sites that have been used for planning purposes are covering areas of 25,000 by 25,000 feet successfully but this is probably pretty much the limit of what area can be covered in a single site in the ONUMA|System.
Please note that the size of the site is determined by any object that is placed in a site plan, i.e. the site polygon itself, buildings, background images, etc. Sites larger than this limit will not show the scales along the edge anymore and zooming out is limited as well (with the scroll wheel or zoom button).
The good news: In the ONUMA|System, users can divide an area into smaller subareas and work on each sub-area with much greater accuracy. These sub-areas can then be combined by selecting the sites in the project list and then clicking on the Report on Selected Schemes or Compare buttons. On the page with the reports, there is also a Network Link which allows viewing of all the selected sites/schemes in Google Earth.
