RasterPixels are used to represent features. Nodes are the start and end points, vertices are the points where there is a change of direction. VectorConstructed by joining points with lines.

* Used by many Network Planning Software tools All projections have a degree of distortion A map projection can preserve area, distance, shape or direction but only a globe can preserve everything! MapInfo has a wide range of projections for displaying maps, it defaults to Latitude / Longitude.Įxamples of ProjectionsSome well known projections are: Mercator Produce maps suited for navigation Lambert Produce maps suited for visual analysis In MapInfo Latitude/Longitude NAD27 Bahamas, Cape etc.* Latitude/Longitude NAD83* Various other options Projections A Projection is a mathematical model that translates the location of features on the Earths surface to locations on a twodimensional surface. Lines of Longitude are farthest apart at the Equator and intersect at both poles, and are therefore not parallel.Ĭonverting Lat & Longs MapInfo uses Latitude and Longitude coordinates in the decimal degrees format.ģ0 minutes = half a degree 30 seconds = half a minute Latitude (+) 41 12 2341 Degrees 12 Minutes 23 Seconds 41 + (12 Minutes / 60 Minutes) + (23 Seconds / 3600 Seconds) 41.206 Latitude lines are the horizontal lines on a map Latitude lines increase from 0 degrees at the Equator to 90 degrees at both the North (+90.0 degrees) and South (-90.0 degrees) poles.Ĭoordinate SystemsLongitude Used to describe the East West position of a point The X-Axis It is reported as the number of degrees East (to 180.0 degrees) or west (to +180.0 degrees) of the Prime Meridian (0 degrees) Represented by vertical lines running from North to South. In GIS it is the graphic presentation and visual interpretation of data.Ĭoordinate SystemsLatitude The North-South position of a point The Y-Axis Measured in degrees or decimal degrees above or below the equator. * Cartography is the art and science of making maps. You create a coordinate system by supplying specific values for the parameters of a projection. In cartography*, coordinate systems are closely related to projections. Those numbers are the coordinates for that point. Each point in a geometric object is represented by a pair of numbers. Adobe Freehand or Illustrator) for creating presentation quality digital maps Questions such as Which county has the highest population? can be answered by a database Questions such as Which county has the highest density of potential customers within 5 miles of potential radio sites? use GISĬoordinate Systems A coordinate system is used to create a numerical representation of geometric objects. What GIS is NOT! GIS is not equivalent to digital mapping There are better programs available (i.e. Spatial relationships between data translate to mathematical expressions and can be evaluated by GIS tools This information can then be geographically identified and related What is GIS? GIS Refers to software tools which use spatial / geographic techniques to visualize and analyze data Typically, GIS is used to relate different types of geographic data.o Polygons (e.g. MapInfo Training Part 2: Advanced Thematic Maps Selections Queries Sample Application MapInfo Training Part 1: Basics Tables Maps Layoutsģ.
