Glossary

Term Description
WGS84 Latitude/Longitude Coordinates Coordinates enabled by WGS84 spheroid: spherical coordinates to latitude or longitude
TW Coordinates Coordinate system on Thinware maps (ThinkWare coordinates)
TM Coordinates With the location of a random area as origin point of coordinate, the meridian traversing the origin point on the plane is displayed as axis X while the parallel between the east and west as axis Y, so that each location can be marked by m under the rectangular coordinate system.
Map Cycle Data exposing information on the background map: information which is exposed properly so as to recognize information on each location, such as administrative names, business names, public institutions, water system, and road name.
General/Aerial Maps General Map: Maps with general background data which are optimized for PC web maps
Aerial Maps: Maps that are photographed on airplane
Administrative Codes Codes that are stipulated in accordance with procedures from standardized administrative codes which are required for tasks of each institution so that information can be shared between institutions
Old Address System (based on land-lot numbers) Land-based address system, like Dong, Li + lot number
Road Name Address System Building-based address system, like road name + building number
Space Search Search within area or radius
Extent Search: Search within areas on top-left coordinates (X,Y)/bottom-right coordinates (X,Y)
Range Search: Search within radius from central coordinates
POI Short for Point of Interest, which refers to buildings or stores which are marked on electronic maps, like navigation
Sub-facilities Facilities included at each POI (e.g. Sub-facilities of Everland: Parking lot 1A , Parking lot 1B)
Stopover A location which is passed by between departure and destination
Keyhole Markup Language, or KML XML standard-based file format to mark geographical data
Developed for Google Earth and now supported for many services, such as Google and HERE Map.
GPS Exchange Format, or GPX XML-based file format to exchange GPS data between Internet application and web services
Classified into waypoint, route, and track, to indicate points and path information
