Project Description

Main objectives:

Update existing digital surficial compilation to include all line and point features. Important for studies that include any aspect of ice-flow, glacial history, lake history, age relationships, and land-use.

Methodology:

• Digitize all line and point features from pre-existing surficial maps.
• Augment dataset with SPOT 4/5 satellite imagery and newly-released LiDAR.
• Ongoing interpretation of ice-flow history, focused on northern Manitoba but eventually the entire province.

 

Benefits:

A strong public geoscience knowledge base is recognized internationally as a key competitive advantage in profiling a jurisdiction’s geological potential and attracting investment in mineral exploration and development. The products from this project will provide input to a number of ongoing environmental, infrastructure and mineral exploration initiatives.

 

Plans for fiscal year 2022–2023:

• Digitization of additional features from remotely-sensed imagery; 6 NTS sheets remaining
• GeoFile 1 and website updates to reflect ongoing updating of point and line features to compilation
