Purpose: Developed as a spatial representation of the hard-copy Historical Count Book, which is . SpeedGauge, a provider of business intelligence and location-based analytics for the trucking and insurance industry, announced a new GPS data accuracy and quality verification technique.

    Data Quality. The utility of spatial data in GIS depends directly on the quality of the spatial data used in the process. Geospatial data quality is measured along at least three different axes: space (location, places), time, and theme (content, characteristics). The space axis characterizes positional accuracy; the time axis indicates. Accuracy Transport, Inc will not be liable for loss or damage caused furs, jewelry, negotiable securities or other high value items etc., unless the item or items are declared at the time of placing the call, in order to afford Accuracy Transport, Inc an opportunity to adequately protect the shipment.

Global Navig Author: Joshua D Kent, Clifford Mugnier, J Anthony Cavell, Larry Dunaway. The correction can be immediately transmitted to the mobile GPS receivers (real-time Differential Global Positioning System [DGPS]) to compute a much more accurate position.

The receiver position can also be corrected at a later time during processing by GPS software. The use of DGPS can greatly increase positional accuracy within 1 m.

Data updates and data accuracy verification are discussed further in section Information Collection made substantial changes to the required NPMS submissions: Required that the pipeline data have a positional accuracy of ±5 feet of its known geographic location.

Jun 03,  · OpenStreetMap (OSM) has been successfully applied all around the world, especially in developed western countries, but this is the first study of the quality of OSM data in China.

Two data quality elements, completeness and positional accuracy, were chosen to conduct the assessment via a comparison against Baidu stevefrithphotography.com by: May 31,  · Extensive studies have focused on assessing the quality, especially the positional accuracy, of OSM data.

One method for assessing accuracy is the buffering approach where a buffer is created around a validated road network using a predefined buffer radius. The percentage of OSM road lengths that lie within this buffer is then stevefrithphotography.com by: 2. Accuracy will be determined and reported using the methodology specified in the FGDC National Standard for Spatial Data Accuracy.
