GNSS for Underwater

/ / Knowledge, Research, Teaching / , , , / 1 minute of reading

The optimal arrangement of buoys is determined in terms of accuracy and availability depending on the number of available buoys and targeted water depth for an efficient operation. For example, at a targeted depth of 30 m in fresh water, a maximum horizontal position root-mean-square (RMS) error of less than 3 m can be achieved with a set of five buoys providing a service radius of up to 72 m. https://doi.org/10.3390/rs12213636 The formal transfer of […]

Common people, often, get confused with the terms Geographic(al) Information System, GIScience, Geomatics, Geoinformatics, Geoinformation Technology and Geospatial Technology. To understand the differences or similarities among them we need to fine-tune our understanding about these frequently used and interchangeable terms. Geographic Information System (GIS) is a computer-based information system used to digitally represent and analyze the geospatial data or geographic data. The GIS has been called an ‘enabling technology’, because it offers interrelation with the wide variety of disciplines which must deal with

Spatial vs Geospatial [2]

/ / Knowledge, Public, Research, Teaching / , , / 3 minutes of reading

Mike Goodchild believes that we should make a distinction between spatial and geospatial believing that if spatial is special then geospatial is even more special! The way he sees it is that geospatial is a subset of something much larger that encompases any spatiotemporal frame, any spatial resoultion, non-Cartesian spaces and metrics and so on.  Spatial represents the big picture while geospatial carves out its own area of interest at on on the earth’s surface  He goes

Spatial vs Geospatial [1]

Often my students ask about the difference(s) between spatial and geospatial. These two words appear very frequently in remote sensing and GIS literature. The word spatial originated from Latin ‘spatium’, which means space. Spatial means ‘pertaining to space’ or ‘having to do with space, relating to space and the position, size, shape, etc.’ (Oxford Dictionary), which refers to features or phenomena distributed in three-dimensional space (any space, not only the Earth’s surface) and, thus, having

Location Privacy

/ / Uncategorized / , , , / 1 minute of reading

Beresford and Stajano define location privacy as “the ability to prevent other parties from learning one’s current or past location.” This definition specifies that the data subject—or the person whose location data is affected—should have control over the use and subsequent use of their data, which can be viewed as an extension of the previously presented definition of privacy. The device’s physical location can be determined using one of three methods: (1) satellite navigation systems
