GIS Development

GIS is a technological tool for assembling, organizing, distributing, analyzing, and visualizing spatially distributed features and the associated attributes for people to make more intelligent decisions. It helps capture, input, transform, store geographic data into layers, linking spatial data with tabular attribute data, provides a common geo-referencing system, and then allows us to view, query, model, analyze, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, images, globes, reports, charts and various on-screen responses to interactive queries.

Here you will find technical articles, developer guides, webinars, and training videos created by NAVTEQ subject-matter experts and members of the NN4D community on GIS development topics.

Mapping, (Reverse) Geocoding, Routing are among most used GIS functions.

Mapping: For many types of geographic operation the end result is best visualized as a map or map images as maps are very efficient at storing and communicating geographic information.

(Reverse) Geocoding: Simply put, geocoding is a process that takes address(es) and assigns estimated location(s) usually in the form of coordinate values to the address(es). Reverse geo-coding, just as what the name suggests, is the reverse process of geocoding, i.e., find the most matched address for a given pair of latitude and longitude.

Routing: Route calculation is to determine the best route between two or more places. Routing function needs a connected network, for example road network, and routing algorithms.  The most commonly seen routing is road routing. It takes x,y coordinate inputs for two or more locations, along with routing preferences, road and traffic conditions, and returns a route map and textual driving directions for the suggested route.


LBS is a growing technology field that focuses on providing GIS and spatial information via mobile phones or other PDA devices. NAVTEQ has been a pioneer and veteran in promoting LBS through NN4D LBS challenge and create and deliver the best LBS eco systems to the developers.
