Landserv’s specialist mapping capabilities are overseen by our Geospatial Manager, Paul Bazalicki. Paul has over 30 years of experience in the three inter-related disciplines of Cartography, Geographic Information System (GIS) and Surveying. These services add value for our clients by mapping the data captured out in the field and producing a visual representation on maps and figures for our deliverables using specialist software packages.
Landserv operates a Trimble GNSS/GPS Survey system. The use of Global Navigation Satellite System (GNSS) and GPS Survey equipment and capabilities ensures extremely accurate data capture of sampling locations, site features and delineation of potentially contaminated areas. Our system uses industry standard data collection techniques backed up with robust field and office survey data quality control. We operate in industry standard data formats so there is no loss of data between field capture to GIS and final product output.
Also adding value to our client’s projects are our Geographic Information System (GIS) capabilities, which we use to store and collate the data captured from our GNSS/GPS in a geo-referenced database. Our GIS allows us to overlay the mapped opportunities and constraints such as:
- Soil contamination;
- Groundwater plumes;
- Flora, fauna, habitat and biodiversity;
- Cultural heritage sensitive areas; and
- Planning Scheme and cadastral property boundaries.
For environmental sampling (soil, groundwater, surface water, soil gas / landfill gas) our analytical data is processed, validated and analysed to identify exceedances of guideline criteria using the ‘ESdat’ specialist environmental database system. Using our GIS we are then able to map and depict our analytical results and criteria exceedances in 2-dimensional maps or 3-dimensional diagrams to estimate volumes of contaminated material.
