Limitations of Tools
• Precision of results• Validity of assumptions?• Reliability of modeling?
• Tools need• Initial design proposal• Fundamental ideas• Creative thinking• User's intelligence
• There are no “self-configuring” tools• “garbage in - garbage out” rule applies strictly
Tools are just tools intelligence is yours!

• Global Positioning System• Based on a constellation of orbital satellites• CDMA coding of the signal, different codes for
civilian or military use• Precision:
• Accuracy of ca. 18m technically feasible• For civilians deliberately (!!) decreased to approx.
• 100m accuracy at 95% probability• 300m at 99.9% probability
• Used to get coordinates of visited sites during site surveys and locating measurements
• Watch out!!! Map datum and GPS datum must be THE SAME, otherwise bigger errors come out

Digital Maps
Layers of one block
One pixel / unit
34 © NOKIA 6-60731/ RADIO NETWORK PLANNING TOOLS/ v 2.0
Digital Map Data
• Pixel (map unit) is the smallest detail of a digital map
• Pixels are squares, defining the resolution of data
• The value of a pixel is an average over the area covered
• Typical resolution 2m... 500m
• All layers of a block have the same resolution
• A map can contain blocks with different resolutions
35 © NOKIA 6-60731/ RADIO NETWORK PLANNING TOOLS/ v 2.0
Geographical Information Systems
• Computer system capable of assembling, storing, manipulating, and displaying geographically referenced information
• Layers of information
• Before the digital data can be analyzed, they may have to undergo other manipulations - projection conversions, for example - that integrate them into a GIS

36 © NOKIA 6-60731/ RADIO NETWORK PLANNING TOOLS/ v 2.0
Datum (1/2)• Geodetic datum (e.g. World Geodetic System 1984, WGS-84) defines
an ellipsoid to transform potato-shaped earth surface to a plane surface. Any rectangular coord. system can then be used on a plane surface.
• Coord. transformation Lat/Long -> rectangular system: a combination of the Ellipsoid used + coordinate system used on plane surface. Most common combination (e.g. in GPS) is WGS-84 ellipsoid + UTM rectangular coord. system.
• Flat-earth models • used for plane surveying
• Complex ellipsoidal models • used for international applications• describe the size, shape, orientation, gravity field, and angular
velocity of the earth.
37 © NOKIA 6-60731/ RADIO NETWORK PLANNING TOOLS/ v 2.0
Datum (2/2)• Referencing geodetic coordinates to the wrong datum can result in
position errors of hundreds of meters
• Different nations and agencies use different data
• The Global Positioning System is based on the World Geodetic System 1984 (WGS-84)
• Requires careful datum selection and careful conversion between coordinates in different data
• Complete datum conversion is based on seven parameter transformations
• translation parameters• three rotation parameters and • scale parameter
38 © NOKIA 6-60731/ RADIO NETWORK PLANNING TOOLS/ v 2.0
Earth Models
• Ellipsoidal earth models are required to• accurate range and bearing calculations over long distances• compute position and waypoint information (Loran-C, and GPS
navigation receivers).
• Reference ellipsoids are defined by major (equatorial radius) and minor (polar radius) semi-axes.
• Other reference ellipsoid parameters such as flattening, and eccentricity are computed from these two terms.
• The best of these models can represent the shape of the earth within about one-hundred meters.

39 © NOKIA 6-60731/ RADIO NETWORK PLANNING TOOLS/ v 2.0
Lat/Long Coordinate System
• Latitude, Longitude, and Height system• the most commonly used coordinate system • reference planes: Prime Meridian and the Equator
40 © NOKIA 6-60731/ RADIO NETWORK PLANNING TOOLS/ v 2.0
UTM Coordinate System
• Universal Transverse Mercator system• defines two-dimensional, horizontal positions.
• UTM zone numbers • designate 6 degree longitudinal strips • extending from 80 degrees South latitude to 84 degrees North latitude.
• UTM zone characters • designate 8 degree zones extending north and south from the equator.
