Is a novel tool that combines both data and uncertainty in a unique and intuitive visual to convey the spatial quality of data (2D and 3D), thus communicating spatial data distribution in a holistic way and allowing decisions to be made with substantially greater confidence.
The VGM uses varying grid cell sizes to visually communicate and constrain the uncertainty; smaller grids representing less uncertainty, and larger grids representing greater uncertainty.
The VGM is a user-driven tool. It gives the user flexibility in the selection of uncertainty criteria and grid resolution, which enables optimal visualization of relevant opportunities versus knowledge gaps.
Information on the quality of your data is underestimated across geospatial visualization tools. As the use of big data and data analytics continues to play an increasing role across virtually all industries, it is crucial that uncertainties are appropriately quantified and represented in final products used to support those decisions. This serves to reduce risks and improve the value of the information presented.
The VGM offers an efficient and effective tool for assessment of spatial data quality and provides an effective validation of the true value of spatial data on hand.
