Accuracy refers to how close a measurement is to the 'true' value, and precision, often called reproducibility or repeatability, is the agreement of repeated measurements. Hitting the center of the target means you are accurate. Read Accuracy & Precision in Data | Definition, Formula & Examples...
High-Precision Static Gnss Surveying:Horizontal:2.5mm+0.1ppm RMS|Vertical:3.5mm+0.4ppm; Static and Fast Static:Horizontal:2.5mm+0.5ppm RMS|Vertical:5mm+0.5ppm RM; Internal Battery:Internal 7.4V/6800mAh Lithium-Ion Rechargeable Bat; Water/Dustproof:IP68; ...
Sources of error have to be recognized and a level of accuracy assigned to the data. Often data layers are combined to produce new data with little regard to the accuracy of the input data. Data in a GIS are often represented as having a much higher precision than that at which they ...
When I say there is a "revolution" going on in GIS, I am referring to the change in the fundamental accuracy and precision kernel of commonly used geographic data brought about by new technologies previously mentioned. For many ArcGIS users, this kernel used to be about 10 meters or 40 fee...
A discussion on different techniques for GIS data collecting, precision, accuracy and quality of database Nowadays, is a common sense the importance of geotechnologies in urban planning, transportation engineering and other different areas of knowledge. The Geographic Information System (GIS) is one ...
Geographical information systems (GIS) are commonly used to evaluate wildlife habitat availability and extent. However, the value of this approach is dependent on the quality of the data being used. We present the results of an effort to assess the accuracy of commonly used spatial data. Historic...
GPS/INS precisionAirborne radio occultationRetrieval accuracyAn airborne radio occultation (RO) system has been developed to retrieve atmospheric profiles of refractivity, moisture, and temperature. The long-term objective of such a system is deployment on commercial aircraft to increase the quantity of ...
