1) Introduction
A) Q. What is a Geographic Information System?
A. Geographic Information System (GIS) is a computer program for storing, retrieving, analyzing, and displaying cartographic data.
Vector Spatial Location Data = X, Y, Z
Attribute Data Base = Data Information
B) The Difference between Raster and Vector Maps
Maps in Geographic Information Systems are represented thematically. A standard topographic map will show roads, rivers, contour elevations, vegetation, human settlement patterns and other features on a single map sheet. In a GIS these features are categorized separately and stored in different map themes or overlays. For example, roads will be stored in a separate overlay. Likewise, rivers and streams will each be stored as a separate theme. This way of organizing data in the GIS makes maps much more flexible to use since these themes can be combined in any manner that is useful. The following illustration shows conceptually how maps are stored as themes in a GIS.
Each different theme is stored on a separate overlay. The overlays on the left represent a vector based GIS, where the information is stored as a series of points, lines and polygons. The overlays on the right represent a raster based GIS, where the information is stored as a series of discrete units called cells.

C) The Relation between Vector Spatial Location and Attribute Data Base
Each Spatial Layer is consist of many Spatial features
Each Spatial Feature consist of many vertexes (x, y, z)
Each Spatial Layer is related to one Attribute Data Base Table
Each Spatial Feature is related to one Attribute Data Base Record
Each Record consist of many fields (up to 255)
D) GIS Shape File types 2D & 3D (Point – Polyline – Polygon)
Shp file contain spatial Location data of each feature Which are:-
o Type 2D & 3D (Point – Polyline – Polygon)
o Number of Parts
o Number of Vertexes
o X,Y, and Z of each vertex
Dbf file contain Attribute Data
o Each Attribute Data table consist of many records
o Each record consist of many fields (up to 255)
Shx file is a relation file between the Shp file and Dbf fie
Point Layer consist of one vertex per Feature(x, y, z)
Polyline Layer consist of many vertexes per Feature
Polygon Layer consist of many vertexes per Feature and closed

2) Coordinates Systems
A) Lon and Lat Geographic Coordinate System
The geographic latitude (abbreviation: Lat., or phi) of a point on the Earth's surface is the angle between the equatorial plane and a line that passes through that point
The North Pole is 90° N; the south pole is 90° S. The 0° parallel of latitude is designated the equator, the fundamental plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres.
The Longitude (abbreviation: Long., or lambda) of a point on the Earth's surface is the angle east or west from a reference meridian to another meridian that passes through that point.
All meridians are halves of great ellipses (often improperly called great circles), which converge at the north and south poles.
B) Universal Transverse Mercator Coordinate System UTM
The UTM system divides the surface of Earth between 80°S and 84°N latitude into 60 zones, each 6° of longitude in width and centered over a meridian of longitude. Zone 1 is bounded by longitude 180° to 174° W and is centered on the 177th West meridian. Zone numbering increases in an easterly direction.
Each of the 60 longitude zones in the UTM system is based on a transverse Mercator projection, which is capable of mapping a region of large north-south extent with a low amount of distortion. By using narrow zones of 6° (up to 800 km) in width, and reducing the scale factor along the central meridian by only 0.0004 to 0.9996 (a reduction of 1:2500), the amount of distortion is held below 1 part in 1,000 inside each zone. Distortion of scale increases to 1.0010 at the outer zone boundaries along the equator.
