Study GeoSpatial Data Science!

GeoSpatial Mapping

In simple terms, geospatial information is geography and mapping. It is “place based” or “locational” information. It is data tied to and portrayed on a map. Whether it is MapQuest, Google Maps, or the in-dash navigation system in your car, everyday citizen use geospatial data more than they know it. - sourced by mapp.org

Geospatial Analytics : Geospatial analytics gathers, manipulates and displays geographic information system (GIS) data and imagery including GPS and satellite photographs. They are used to create geographic models and data visualizations for more accurate modeling and predictions of trends.

Application of Geospatial
Geospatial technology refers to equipment used to measure and analyze Earth's land and features. Systems such as Global Positioning System (GPS) and Geographical Information System (GIS) are used in geospatial work. ... GPS can also be used in outdoor recreational activities such as hiking, fishing, kayaking, and boating

Geospatial Technology types
Geospatial technology involves GPS (global positioning systems), GIS (geographical information systems), and RS (remote sensing).

Geospatial technology takes several forms: remote sensing, geographic information systems (GIS), the global positioning system (GPS), geographically referenced land process models, and 3-D landscape visualization.  Remote sensing is an excellent tool for rangeland managers.



Examples of Geospatial Data
Geospatial data, or spatial data (as it's sometimes known), is information that has a geographic aspect to it. In other words, the records in this type of information set have coordinates, an address, city, postal code, or zip code included with them. The most obvious example is a road map.

GeoSpatial data collected
Collection of coordinate information in the field: Coordinate information can be collected in several ways in the field, such as by using a global positioning system (GPS) device or GPS built-in devices, by using high-resolution satellite images, and by address matching/geocoding (conversion of addresses to X, Y .

Difference between spatial and geospatial
As adjectives the difference between geospatial and spatial
is that geospatial is of or pertaining to a geographic location, especially data while spatial is of or pertaining to space.

Geospatial Industry
The geospatial industry comprises of government organizations, private companies, non-profit organizations, and academic and research institutions that develop, manufacture, research and employ geospatial technology.

Geospatial data has been used by law enforcement agencies to predict and prevent crime in several ways: Mapping. Police or other agencies can utilize data from multiple sources and visualize it on layered maps.

Why is Geospatial Data important?
During natural disasters, geospatial data plays an important role in risk management regarding transportation routes. Use of geospatial data informs strategic planners of potential routes that could be impacted due to the risks inherent to geography. These data also help identify evacuations routes.

Methods for Creating Spatial Databases
  1. Manual Digitizing. This is traditionally the most common way to convert paper-based sources of spatial information (e.g. maps) to digital data.
  2. Heads up digitizing.
  3. Coordinate Geometry (COGO) 
  4. Geocoding. 
  5. Global Positioning Systems (GPS) 
  6. Image Processing.
  7. Related GIS Data Resources.
There are many tools that geographers use including maps, which are two-dimensional drawings of the earth, rendered by cartographers; GPS or global positioning system, which uses satellites to locate latitude and longitude and get directions; and GIS or geographic information system, which is a database that collects .

Geographic information systems (GIS) have been used for many years to integrate social and territorial information in quantitative research, but only recently have they been used in qualitative research.

What makes Geospatial Science different? 
What differentiates the discipline from other sciences is that the conclusions include a spatial component. This makes for stronger conclusions and a better understanding of the world, thus allowing decision makers from multiple disciplines to be better informed.

Yes, spatial data is special. Location does matter. Nearby events are more correlated to one another. Spatial data calls for special techniques to tackle autocorrelation problems.

Geospatial analysts examine a range of data from the geographical record including aerial photographs, GIS data, the cartographic record (which includes old maps, new maps, specialist maps such as soil and geology maps), satellite data, soil analysis and other environmental samples, and any academic literature.
Google Earth provides search capabilities and the ability to pan, zoom, rotate, and tilt the view of the Earth.  Google Earth is not a Geographic Information System (GIS) with the extensive analytical capabilities of ArcGIS or MapInfo, but is much easier to use than these software packages
