AERMAP Terrain Data

Elevation data specifications

Digital Elevation Model (DEM) data is used by AERMAP to determine source and receptor elevations and terrain characteristics.

Coverage Global*
Elevation Dataset SRTM DEM
Spatial Resolution 30 m / 90m
Data Format GeoTIFF / HGT

* SRTM coverage is generally limited to approximately 60°N to 56°S.

Terrain Processing

AERMAP terrain processing in one click

Sources and receptors already exist in the project. AERMOD One uses the modelling domain to determine exactly what terrain data is required and prepares everything else automatically.

Click once. The complete terrain processing workflow runs internally.

Have your own terrain data?
Upload it. AERMOD One checks the coordinate system, transforms it where required and prepares it for AERMAP.
AERMOD One Automatically
Calculates the required terrain extent
Downloads required elevation tiles
Mosaics and crops terrain data
Handles coordinate transformation
Generates AERMAP input
Returns processed elevations to AERMOD

Automation

Automated by
AERMOD One

AERMOD One streamlines terrain data acquisition and processing, reducing manual GIS preparation for AERMAP.

Automatic Data Retrieval

Identifies and retrieves elevation data covering the modelling domain.

DEM Processing

Downloads, mosaics and clips elevation tiles to the study area.

AERMAP Input Preparation

Manages coordinate transformations and prepares terrain inputs for AERMAP.

Project Data Retention

Retains the selected terrain dataset with the project for future use.
