Intelligence to specify
Given how much we can achieve in the field of geospatial science, there are of course areas of specialisation. What specialisation you decide to focus on will come down to your interests, and whether you’d rather work in a city, rural or coastal area.
Read on to find out a little bit about geospatial science’s specialisations.\
Geodesy is a science of the measurement and mapping of the earth’s surfaces. Geospatial scientists in this field track rising sea levels, measure earthquakes and continental drifts using instruments like GPS, laser technology and electronic distance devices to measure global parameters and locate positions accurately on the earth’s surface for global mapping, research and natural disaster prevention studies.
Topographic geospatial scientists measure elevation points on land and the environment. Topography is related to cartography and mapping, which involves plotting points as contours of the earth’s surface including; valleys, rivers and lakes on a map by making field measurements and taking aerial photographs to develop maps.
Geospatial scientists monitor changes on the earth’s surface using satellites and other digital technologies to monitor for trends in the environment. The data collected is then used for research and emerging environmental studies. Geospatial scientists in this field are involved in creating maps for Google Earth and Street View technologies.
Geographic information systems are used widely for planning decisions. A geospatial scientist in this field is involved in the visualisation, design and development of data content for online and mobile phone mapping and navigation. In-car navigation systems use maps which are provided by the work of geospatial scientists.
