      Defining GIS

      A GIS is a computer system capable of capturing, assembling, storing, manipulating, analyzing and displaying geographically referenced information. With GIS, users can create interactive queries, analyze spatial information, edit data, integrate maps, and present the results of these tasks. GIS can be used to solve the location-based questions such as “What is located here” or Where to find particular features? GIS user can retrieve the value from the map, such as what proportion is the vegetation cover in a land use/ land cover (LULC) map. This can be done using query builder tools.

      Three views of GIS

      Many have characterized GIS as one of the most powerful of all information technologies because it focuses on integrating knowledge from multiple sources and creates a crosscutting environment for collaboration. In addition, GIS is attractive to most people who encounter it because it is both intuitive and cognitive. It combines a powerful visualization environment with a strong analytic and modeling framework that is rooted in the science of geography.
      This combination has resulted in a technology that is science based; trusted; and easily communicated across cultures, social classes, languages, and disciplines.

      To support this vision, GIS combines three fundamental aspects or views:

      The geodatabase view: A GIS manages geographic information. One way to think of a GIS is as a spatial database containing datasets that represent geographic information in terms of a generic GIS data model— features, rasters, attributes, topologies, networks, and so forth.
      GIS datasets are like map layers; they are geographically referenced so that they overlay onto the earth's surface. In many cases, the features (points, lines, and polygons) share spatial relationships with one another. For example, adjacent features share a common boundary. Many linear features connect at their endpoints. Many point locations fall along linear features (e.g., address locations along roads).

      The map view: A GIS is a set of intelligent maps and other views that show features and feature relationships on the earth's surface. Various map views of the underlying geographic information can be constructed and used as windows into the geographic database to support query, analysis, and editing of geographic information. Each GIS has a series of two-dimensional (2D) and three-dimensional (3D) map applications that provide rich tools for working with geographic information through these views.

      The geoprocessing view: A GIS is a set of information transformation tools that derive new information from existing datasets. These geoprocessing functions take information from existing datasets, apply analytic functions, and write results into new derived datasets. Geoprocessing involves the ability to string together a series of operations so that users can perform spatial analysis and automate data processing—all by assembling an ordered sequence of operations. There are numerous spatial operators that can be applied to GIS data. The ability to derive new information within a GIS analysis process is one of the fundamental capabilities in GIS.

      Raster data

      Difference Between spatial and no spatial data

      Geographic data types

      Two kinds of data are usually associated with geographic
      features:
      1. Spatial data
      2. Non- spatial or attribute data
      Spatial data refers to the shape, size and location of the feature. Spatial data sets are primarily defined as those which are directly or indirectly referenced to a location on the surface of the earth. The spatial data sets, however has primary data type as point, line or polygon and may be referenced to some specific grid system.
      Non- spatial data/ attribute data refers to other attributes associated with the feature such as name, length, area, volume, population, soil type, etc. When a dataset cannot be related to a location on the surface of the earth is referred as non spatial data. The non spatial data are numbers, characters or logical type.

      Data storage in GIS

      In contemporary geographic information systems, geospatial data are stored as digital data. This binary representation allows a high level of flexibility and accuracy in the representation and processing of data.
      The most important feature of GIS is that spatial data are stored in a structured format referred to as a spatial database. The way spatial data are structured will determine how easy it is for the user to store, retrieve and analyze the information.

      What is GPS?

      The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial users around the world. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver.

  • Map Scale

    • Map Scale File

      Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground.

      Map scale is often confused or interpreted incorrectly, perhaps because the smaller the map scale, the larger the reference number and vice versa. For example, a 1:100000 scale map is considered a larger scale than a 1:250000 scale map.
      Geoscience Australia has complete 'small scale' reference map coverage of Australia at scales of 1:2.5, 5, 10 and 20 million. We maintain a complete national topographic map and data coverage at 1:1 million and 1:250000 scale. We have an incomplete map and data coverage at 1:100000 and 1:50000 scales. We also produce digital products for several of these categories as well as a number of themed maps.
