This GIS grid reference was used for each of the herds that were sampled and tested in this study.
All Irish herds have a GIS grid reference, which is based on the centre point of the largest parcel of land associated with the herd in question.
The work was conducted using geographic information systems (GIS), with all data referenced to the position of relatively stable islands.
In our digital world it should be fairly easy to cross reference GIS mapping, crowd sourced information (using mobile technologies) and online accountability to create a more transparent system of aid.
Subsidence at the surface points is calculated from the 3D polygon panels as geometrical excavation areas, and each panel of the polygon is referenced to the global coordinate system in GIS.
GIS allows a user to represent data (also called "attributes") referenced by their geospatial coordinates.
GIS facilitates monitoring underground safety by allowing the use of spatially referenced data, in which the system functions through its database and management tools, processing and analysis tools, and featured display tools (Dijk, PM van et al. 2004).
Using spatial and tabular tools within GIS, modeled emissions from the ISC dispersion models were aggregated into spatially referenced data sets and combined with underlying census demographic data.
Advances in GIS and statistical methodology together with the availability of high-resolution, geographically referenced health databases present unprecedented new opportunities to investigate the environmental, social, and behavioral factors underlying geographic variations in disease rates at small-area scale.
GIS are computer systems that allow the collection, storage, integration, analysis, and display of spatially referenced data.
