Map projection More generally, the surfaces of planetary bodies can be mapped even if they are too irregular to be modeled well with a sphere or ellipsoid; see below. Even more generally, projections are the subject of several pure mathematical fields, including differential geometry and projective geometry. However "map projection" refers specifically to a cartographic projection. Background[edit]

MapServer Demonstration Installation Instructions Pericles S. Nacionalespnaciona@gis.umn.edu02 February, 2002 Traduction : F.A VAN DEN BUSSCHE (Club des Utilisateurs Linux de Toulouse et des environs - CULTe Relecture : Nathalie VIELMAS (Club des Utilisateurs Linux de Toulouse et des environs - CULTe) Ce document donne les instructions de base pour paramétrer l'application de démonstration de MapServer. Il est considéré ici que le programme CGI de MapServer ( mapserv ou mapserv.exe) a été installé sur le serveur oueb dans le répertoire cgi-bin.

Geographic information system - Wikipedia, the free encyclopedia A geographic information system (GIS) is a computer system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data. The acronym GIS is sometimes used for geographical information science or geospatial information studies to refer to the academic discipline or career of working with geographic information systems and is a large domain within the broader academic discipline of Geoinformatics.[1] What goes beyond a GIS is a spatial data infrastructure, a concept that has no such restrictive boundaries. In a general sense, the term describes any information system that integrates, stores, edits, analyzes, shares, and displays geographic information. GIS is a broad term that can refer to a number of different technologies, processes, and methods.

GPS eXchange Format GPX, or GPS eXchange Format is an XML schema designed as a common GPS data format for software applications. It can be used to describe waypoints, tracks, and routes. The format is open and can be used without the need to pay license fees. Its tags store location, elevation, and time and can in this way be used to interchange data between GPS devices and software packages. Such computer programs allow users, for example, to view their tracks, project their tracks on satellite images or other maps, annotate maps, and tag photographs with the geolocation in the Exif metadata.

NTICS: Que son las Ntics La Ntics en Colombia un importante aporte para nuestras generaciones. a. Que se conoce como NTIC´s Las tecnologías de la información y la comunicación (TIC) son un conjunto de servicios, redes, software y dispositivos que tienen como fin la mejora de la calidad de vida de las personas dentro de un entorno, y que se integran a un sistema de información interconectado y complementario. Las nuevas tecnologías de la información se refieren a todos los nuevos medios que, en los últimos años, han facilitado el flujo de información (internet, el videodisco digital [DVD], los computadores portátiles y todos los aparatos tecnológicos que sirven para producir, desarrollar y llevar a cabo la comunicación). Las Tecnologías de y Comunicaciones ofrecen una oportunidad única para que los países en vía de desarrollo den un salto en su evolución económica, política, social y cultural, disminuyendo la brecha que los separa de los países desarrollados.

Diving Into GIS: A Starter Guide The premise of a GIS is this: You take a basemap with features to help you visualize the geographic location, then add data layers, called "Feature Layers," that are delivered from a database. The records in the database include values and labels, as well as fields with X and Y values to geospatially tie the data into the map. More elaborate geospatial tie-ins are created with "Shapefiles." Hidden fields can be used too. If you were looking at television weather maps during last week's U.S. tornado activity, you were looking at a GIS, or Geographic Information System. Those red and purple splotches racing across the screen represented intensity levels of rotating storm cells.

Basic Uses of GIS Guest GIS Contributor Justine Nofal writes about some of the basic types of spatial analysis using GIS. A GIS (geographic or geospatial information system) allows you to record a base map with a geospatial referencing system such as longitude or latitude and then to add additional layers of other information. Importantly that information is identified using the same geospatial referencing. The GIS then allows the individual layers, or themes as they are called to be linked. Analysis of the information can then be undertaken using the statistical and analytical tools that are provided as part of the GIS. By providing spatial analysis of suitably coded data it is possible to provide striking, visual representations of data.

If I Were a Small City GIS Manager By Adam Lodge on January 03, 2012 If I were a small city GIS manager ...I would deploy significant portions of the City's GIS infrastructure using free and Open Source technology. Why?... why not? GIS Glossary - GIS Wiki From abbreviation A shortened form of a word or phrase which represents the whole.
