Web Mapping and GIS Final Exam 2022 with complete solution concept of standards and their use both outside of and for the geospatial industry Why have them? Be able to explain why important for ... web mapping and GIS - Standards makes things more efficient and effective by establishing norms 19500 standards International Standards Organization Goals of standards is to communicate, execute programs, or transfer data with user having little or no knowledge Software engineered to work with different formats major standards organization for the geospatial industry and how it is comprised - Open Geospatial Consortium Data, systems, and process standards Specific standards for many industries (aviation, energy, sensor webs) specific geospatial standards - Geo(JSON) (Javascript Object Notation)- lightweight data interchange format KML (Keyhole Markup Language)-points,rasters,lines,polygons, defines visualizations WMS (Web Map Service)-standard for requesting and serving georeferenced map images over internet..how HTTP requests and responses are handled between client/server. rendered on the fly, WMTS (Web Map Tile Service)-predefined image files WFS (Web Feature Service)-standard for reading/writing vector geographic data WCS (Web Coverage Service)-retrieval of actual geospatial data GML (Geography Markup Language)- exchange standard, modeling language for geographic systems GPX (GS eXchange Format)- stores GPS data XML (eXtensible Markup Language)-standard for exchanging and storing data/documents there are data formats that are widely used but not necessarily adopted by standards organizations - their specifications are published and open so software can be built to use them WMS and WFS - Web Mapping Service and Web Feature Service WMS-standard for requesting and serving georeferenced map images over internet..how HTTP requests and responses are handled between client/server. rendered on the fly, WFS-standard for reading/writing vector geographic data contrast WMS with WMTS - Web Mapping Service- around longer, more flexible for returning custom georeferenced map images, clunky with potential for slower responses Web Map Tile Service-standard for delivering tiles, potentially reduces data and thus bandwidth...more efficient [Show More]
