  • Online map services of Slovenia


    Online map services of Slovenia are based on data provided by the Surveying and Mapping Authority of the Republic of Slovenia, such as orthophoto covering entire territory of Slovenia with detailed imagery taken from a plane rather than satellite, and combine them with additional contents that are of interest to tourists and residents of Slovenia. Orthophoto images are taken every second year and provide more detailed aerial view of entire territory whereas satellite imagery shown by Google Maps only use detailed images for city areas and along major roads, but not for the entire territory. This is why orthophoto images are cited by geographers to show environmental change, rather than images taken by satellites that are shown on Google Maps.Najdi.si combines orthophoto maps (despite its aerial view tab being named "satellite") with other contents, such as traffic info, city bus lines for Ljubljana and Maribor, and current info on the number of available bikes at BicikeLJ stations in Ljubljana.Geopedia.

  • Rubbersheeting


    In cartography, rubbersheeting refers to the process by which a layer is distorted to allow it to be seamlessly joined to an adjacent geographic layer of matching imagery, such as satellite imagery (most commonly vector cartographic data) which are digital maps. This is sometimes referred to as image-to-vector conflation. Often this has to be done when layers created from adjacent map sheets are joined together. Rubber-sheeting is necessary because the imagery and the vector data will rarely match up correctly due to various reasons, such as the angle at which the image was taken, the curvature of the surface of the earth, minor movements in the imaging platform (such as a satellite or aircraft), and other errors in the imagery.

  • Web mapping


    Web map app in smart phoneWeb mapping is the process of using the maps delivered by geographic information systems (GIS) in World Wide Web. A web map on the World Wide Web is both served and consumed, thus web mapping is more than just web cartography, it is a service by which consumers may choose what the map will show. Web GIS emphasizes geodata processing aspects more involved with design aspects such as data acquisition and server software architecture such as data storage and algorithms, than it does the end-user reports themselves. The terms web GIS and web mapping remain somewhat synonymous. Web GIS uses web maps, and end users who are web mapping are gaining analytical capabilities. The term location-based services refers to web mapping consumer goods and services . Web mapping usually involves a web browser or other user agent capable of client-server interactions. Questions of quality, usability, social benefits, and legal constraints are driving its evolution. The advent of web mapping can be regarded as a major new trend in cartography.
