This document acts as a started guide to HerTZ Mapper, the radiocommunication network planning tool for
V/U/SHF that is flexible enough to be used either in the office using desktop computers, or out in the field
using a portable PC. HerTZ Mapper uses specially adapted geographic information including a Digital Terrain
Model (DTM) and digitised map images, in order to facilitate the following tasks:
Line of sight calculation
GPS interface capabilities
Should additional information on specific areas be required please contact our Sales team at firstname.lastname@example.org
1.1 Installing the software
To load the software you must be using a Windows based personal Computer, i.e. Windows 95 or higher. The
software needs then be installed :
The free trial version, limited in its functionalities
The commercial release of HerTZ Mapper
In the next pages, the functions that are not available in the free version will be highlighted in grey.
1.2 Starting the software
From the Windows start menu navigate to the ATDI software selection within programs.
Click on HerTZ Mapper image/icon. :
In case the free trial is used, HerTZ Mapper will indicate the free mode option in the title bar :
Once the package has opened click on the middle of the screen.
Main screen of HerTZ Mapper Web (this screen might be different for the commercial release of HerTZ Mapper)
2 Project management
2.1 Cartographic environment To load a project, use the Files menu in the top left and select Create new file server.
File server menu (left : commercial release, right : Web trial release)
The user has then to specify a name for the project he is about to create.
svr file creation (left : commercial release, right : Web trial release)
Once done, click on Save.
Each cartographic files are then defined by double-clicking on the corresponding layer :
In order to go further, several files are mandatory :
Mode GEO file IMG file SOL file
Coverage & profile Mandatory Mandatory Not mandatory but improves the
accuracy of the simulation
NOT availab e in Free Mode lNot used Mandatory Not used
NOT availab e in Free Mode lNot used Mandatory Not used
Once the cartographic files have been defined, click on OK.
The rest of the document will focus on the Coverage and profile mode.
This shows 2 map layers an Image on the left and the Digital Terrain Model on the right. These are essential
features of the tool:
The Digital Terrain Model (DTM) is crucial to the calculation process; this contains the terrain height
information for each point on the map area. The number of points is determined by the resolution e.g.
using a 50m resolution map will result in heights at every 50m so a 1km square would have 200 x 200
squares & thus 40,000 measurement points. The selection of the appropriate resolution map is
important in assuring the required confidence in the calculation result, for example if 1km resolution is
used many terrain features may be missed.
The image layer does not form a part of the calculation process, but is really essential to visualise the
A Clutter layer can also be utilised with HerTZ Mapper, this is not available in the demo version but can be
used with the full version. This layer is useful in describing areas on the ground such as building, lakes, trees,
etc. such that they can be accounted for in the calculations. Below is a sample of the clutter layer:
Clutter Area with defined height. (Heights can be modified)
The map data layers described are not supplied as a part of HerTZ Mapper software, but ATDI can supply
various types for most parts of the world ready to use with HerTZ Mapper.
Free data can also be downloaded from the ATDI web site www.atdi.com (500m DTM with a 100m map for
the entire world, 100m DTM with 100m map for the USA).
2.2 Setting up a transmitter Clicking anywhere on the image in the image window causes the following floating menu. Move the mouse
down to Add Site.
There are then two options either to place the site using the cursor on the map or by entering the co-
ordinates of the site via the keyboard.
Selecting the co-ordinates option causes the following prompt box to appear. To position the site the Eastings
x/long and Northings y/lat must be typed in.
HerTZ Mapper handles all major coordinates systems and projection types :
Mainly used ellipsoids (WGS84, GRS80, NAD83)
Main coordinate units (Decimal degrees, Degrees Minutes and Seconds, Arc seconds, MGRS (Military
Main projections : UTM North and South, Geographic, Lambert
Once the position of the site is defined the other site parameters may be defined, including the transmit
frequency, antenna height, transmitter ERP and antenna pattern. This is available in the Station Parameters
Box that pops up once the site location is selected.
Clicking the H Diag. tab bring ups the antenna pattern (in the diagram below a specific pattern has already
The antenna H and V patterns can be changed manually or it is possible to load antenna patterns in simple
Once loaded the antenna pattern can be visualised using the 3D tab.
When the station set up is complete click OK and the site is then marked on the image with an icon of a red
square and site designator letter. To move, delete or change the parameters of a site click on its icon. Once
you have clicked on the site you are presented with the following menu.
Clicking on the transmitter in this case A Site number 1 brings up the following menu :
Clicking on Move Tx permits new coordinates to be entered. [In the DTM window using this permits you to
move the Tx using a cursor, use the enter key to accept a new location]
Clicking on Profile allows you to show a path profile and link budget (Link budget not available in Free
mode) from the site to any selected point on the map.
Clicking on Line of Sight shows areas on the mapping that you will have line of sight with from that
Clicking on Coverage start
