Geomatica Exploration and Geology Preamble

• The exploration and exploitation of oil and

minerals is an important industry that shapes our

everyday lives

Geomatica Exploration and Geology Preamble

• Geomatica offers a vast array of

algorithms, tools, and workflows for

exploration and geological applications

Geomatica Exploration and Geology Preamble

Geomatica Exploration and Geology Examples

• Lineament Extraction

• Dip and Strike (mineral exploration)

• Event Mapping and Monitoring

Lineament ExtractionWith Geomatica

What is Lineament Extraction

Lineament extraction is the process of delineating

linear features from imagery or elevation models

Linear features that are an expression of the underlying

geological structure(Faults, etc.)

Why Extract Lineaments

• Site selection (roads, bridges, etc.)

• Structural mapping

• Groundwater exploration

• Mineral exploration

• Oil and gas exploration

• Hot spring detection

• High to low resolution data that can either be a

digital elevation model, optical satellite image,

radar satellite image, or an aerial photo.

What Data is Required
