# LandOpps > California environmental site discovery platform. Full-text search across 20 million pages of GeoTracker and EnviroStor PDFs to find undervalued, mistitled, and overlooked land. LandOpps converts California's two main environmental regulatory databases — GeoTracker (water-resource records, including LUST cleanup sites) and EnviroStor (toxic-substances records, including Brownfields and Federal Superfund sites) — into a discovery engine. Users include real estate developers, environmental project managers, environmental attorneys, and insurance archeologists. The platform lets them search inside 2 million indexed PDFs to find brownfield acquisition targets, identify contamination patterns, shift legal liability, and locate state-funded cleanup opportunities before they become public. The pages below are LandOpps's public marketing and educational content. Authenticated product pages (search, document detail, site detail, dashboard, favorites) are not listed here — they require a paid subscription with a valid credit card and are not indexable. ## About the Company - [About LandOpps](https://landopps.com/about): Company background, what the platform does, and how it differs from traditional environmental due-diligence tools (validation tools vs. discovery engine). - [Contact](https://landopps.com/contact): Email and contact details for sales, support, and partnerships. - [Sign up — 7-day free trial](https://landopps.com/signup): Free trial sign-up.
