LandWatch detects and helps avoid land activities that may pose risks within defined areas. LandWatch is a versatile web-based application to monitor and manage land activities in and around customer-defined areas-of-concern. LandWatch continuously monitors selected land activity occurring at or near monitoring zones. LandWatch alerts pro-actively to enable our customers to control at-risk events before the damage occurs. For over fifteen years, large corporations and government agencies have used LandWatch to monitor and manage portfolios of properties. This is a test.


If it can be mapped, LandWatch can monitor it. The targeting process identifies the areas of concern and tailors the monitoring sources to match the risks at a site. LandWatch can be deployed for small single properties, large multi-property sites, pipeline or rail corridors, regional groundwater plumes, meandering marshes, and other areas of concern or sites. For defined sites, a tailored monitoring approach can be deployed for each site or even within many zones within a single site.


Monitoring covers land activity monitoring, field inspection monitoring, and remote device monitoring. Land activity monitoring involves the automatic collection, filtering, and review of numerous land activities via a combination of automated and manual data collection. With a growing library of over 500 land activity data sources, LandWatch monitors excavation via a national network of Call-Before-You-Dig systems, land development, ownership changes, water wells, building permits, new day care, a new tenancy, zoning, among others.

LandWatch can also help manage property inspections and other on-site “affirmative obligations” with scheduling tools and mobile applications for collecting site inspection data. Finally, LandWatch Remote can monitor remote sensors, such as vapor intrusion mitigations sensors, to detect system anomalies or malfunctions. Our LandWatch operators continuously review monitoring data and when pre-designated criteria are exceeded, then send alerts via e-mail or text.

Alert and Manage

The alert and manage process involves flexible tools that notify and alert when monitoring data detects risks, business processes to help address the risks, and a powerful web application that stores monitoring data and alerts, and provides evaluations and reports of past activities. The alerting tools can send customized private alerts only to clients or their consultants, and/or send an e-mail or text notifications and advisories to 3rd parties.

Often LandWatch users elect to send e-mail or mailed advisories to new owners or excavators, notifying them of residual contamination or sensitive habitat. When monitoring triggers an alert, LandWatch tools both continue to monitor and help support the resolution of the alert. Finally, a secure web portal allows managing a single land activity alert, or observing and evaluating current and past activities across a global portfolio of sites.

LandWatch can generate monthly reporting that summarizes key metrics, maps and then tabularize the month's alerts. Clients can device automated workflows where land events trigger advisories to third parties, and opt-out of alerting, thereby have outsourced land stewardship to the Terradex team.

Versatile to Multiple Land Use Control Scenarios

LandWatch can be applied to mutliple use cases. Classically, LandWatch has been applied at nearly 4,000 facilities to help assure the effectiveness of institutional and engineering controls around areas of land contamination. Working with partners, Terradex has introduced EcologyLand Watch. With Ecology LandWatch an land trust manager or openspace manager can be aware of encroachment on future damage to managed habitat. Furthermore, to protect linear pipelines, Terradex has introduced Pipeline LandWatch. Pipeline LandWatch has enabled effective stakeholder communication upon detection of property sale as well as future development. In all cases, advance awareness by the client controls liability, protects the environment and helps assure complaince.
