Overview

Network planning and modelling tools require data defining terrain, buildings and vegetation to enable the construction of radio path profiles and analysis of predicted wanted and unwanted signals. Projects need data covering towns and cities, roads, railway lines, postcode sectors so that performance can be mapped to requirement. ATDI can supply all types of map data for every country in the world.

Map data types:

DEM: a three-dimensional digital elevation (or terrain only) model defining the environment. SRTM is a good example of terrain data

Clutter data: specifying ground usage as buildings and vegetation in the environment

Buildings model: specifying the actual buildings and tree heights across the terrain

Raster images: variety of scales to link planning to reality

Vector data: defining railway lines, roads, points of interest, fibre, cable or any non-radio artefacts

Subscriber definitions: population, businesses, dwellings and other points or clusters describing centres of service demand

Data are defined primarily by scale (one datum point per linear distance on the ground) and extent (town, county, territory or region).
