Intermap uses aircraft equipped with interferometric synthetic aperture radar technology to capture elevation data. This supplements satellite-acquired data to produce detailed 3D digital models and geometrically correct (orthorectified) imagery of terrain.

Digital surface models under the Nextmap product range include vegetation and cultural features such as buildings and roads, while its digital terrain models have these features digitally removed to aid other project planning requirements.

Geoimage will also distribute Intermap's orthorectified radar images of the earth's surface which remove geometric distortions caused by the terrain.

The distribution of the Nextmap range will complement Geoimage's existing offerings which include high resolution orthoimage mosaics and digital elevation models created from optical satellite imagery.

Geoimage said IFSAR data was especially useful for acquiring elevation data over cloud affected regions such as South East Asia.

"Having access to good quality elevation data in Southeast Asia that is not cloud-affected is a significant advantage for our clients," Geoimage chief executive officer Wayne Middleton said.

"This is an important agreement for Geoimage and we are very excited to form a relationship with a renowned data supplier like Intermap."

Geoimage has already created the first low-cloud Landsat image of PNG and this product is expected to aid a variety of industries, especially in the realms of project infrastructure planning.
