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).
