Using digital technologies in the process of preserving the cultural heritage record is an integral part of all of our projects at ASI. Our geomatics team is comprised of experts in geographic data collection and spatial data analysis. We use some of the latest field techniques for data capture, including unmanned aerial vehicles for photography, total station theodolite (TST) survey and high precision GPS survey which allow us to create accurate data sets for the purposes of heritage management, predictive modeling and historical GIS analysis. This in turn aids in creating a more streamlined and efficient workflow that is capable of adapting to all types of cultural heritage projects.


Remote Sensing

Remote sensing is a cost-effective, non-intrusive and quick way of identifying archaeological and heritage features in advance of development. These techniques are especially relevant in sensitive and protected archaeological and heritage sites. The main techniques used are geophysical survey techniques such as magnetometry, ground-penetrating radar, electrical resistance and electromagnetic survey as well as aerial photography and LIDAR surveys. All require specialist equipment and expert analysis of the results which we can provide.

Our experienced survey teams are able to create an appropriate survey work plan for any property or site. Our staff use state-of-the-art technologies combined with the relevant software and can process all data on a GIS platform. All our geophysical work is carried out in accordance with the provincial standards and guidelines.



Accurate Survey

ASI can accurately map features, such as artifacts, with sub centimetre accuracy using total stations. These features can be plotted on development plans with sub metre accuracy using survey-grade GPS unit. By implementing these tools ASI can complete field surveys more accurately and more efficiently.

Spatial Analysis

From determining archaeological potential, exploring cultural landscapes to better understanding the relationship of cultural features spatial analysis is a key component of all of ASI’s projects.

Historical Mapping Analysis and HGIS

Historical mapping plays a major role in examining our past. Combining primary sources with GIS technologies gives us more analytical tools for historical research. From individual properties to entire communities historical mapping and GIS play a vital role in our research.
