Geospatial data comes in many forms and formats, and its structure is more complicated than tabular or even nongeographic geometric data. It is, in fact, a subset of spatial data, which is simply a data that indicates where things are within a given coordinate system. The stoppage posts on a highway, an engineering drawing of an automobile part, and a rendering of a building elevation all have coordinate systems and can be represented as spatial data when properly digitized. Such coordinate systems, however, are local and not explicitly tied or oriented to the Earth's surface; thus, most digital representations of mileposts, machine parts, and buildings do not qualify as geospatial data. There are many ways to define a terrestrial coordinate system and also to transform it to any number of local coordinate systems, for example, to create a map projection. However, most are based on a framework that represents a planet as a sphere or spheroid that spins on a north-south axis, and which is guided by an equator,which is an imaginary plane midway between the poles and perpendicular to the rotational axis.
An electronic map, whose operation is based on a combination of graphic elements assigned to it in the form of electronic information can be termed as digital map.The digital maps are available in many forms including mobile apps, georeferenced PDFs and TIFF images, online map tiles, and vector data for use in geographic information systems (GIS). Now a day’s people can access digital maps via their cell phones, tablets, and GPS systems. They can also use search engines like Google to view mapping data faster online. Mostly they rely on digital maps to find local restaurants, hotels, gas stations, and other amenities. Judging by the speed of progress, tomorrow’s graduates will take this technology even further.In addition to standalone applications, mapping software comes integrated with many cars. The power behind digital maps has inspired the automakers to make a play for Nokia’s mapping software. However, even thelogistics companies can also benefit tremendously from digital maps.
3D interactive maps of snow and mountain destinations with a high level of realism for a better planification, orientation and security. A 3D realistic map is a map which attempts to simulate a real location or a realistic place as closely as possible. Realistic 3D maps make searching for recreational and tourist information-a fun online experience. 3D realistic maps are an innovative and alternative to topographic maps and traditional mountain panoramas. Visicom produces digital 3D realistic maps for any territory providing customized solutions for each client. These 3D realistic maps are createdfrom stereo pairs of high-resolution, most up-to-date satellite imagery and very in accuracy and details. Realistic 3D maps make searching for recreational and tourist information-a fun online experience. This offers a different platform for digital mapping with the development of a new type of interactive mapping. It allows:
- The contextualization and the highlight of the information in its environment
- Interactivity and collaboration
- Aggregation, search and visualization of all types of data
- Awesome representation of local heritage and territories
