About GEOSLN
GEOSLN provides geospatial APIs and consulting services. GEOSLN is dedicated to democratizing access to critical hazard risk and vulnerability data to non-GIS professionals. There is a large rift between geospatial and other business sectors, especially real estate. As a small business, we seek to serve often undeserved small businesses and individuals. It is our goal to enable our users to understand GIS data without the need for GIS professionals. If you still need a geospatial professional, we can provide consulting as well. Our consulting helps you get on your feet and back to your business.
Our Mission
We transform inaccessible public hazard data into actionable insights. Global datasets for flood risk, wildfire vulnerability, and other natural hazards are freely available. However, they remain difficult for non-geospatial professionals to use. We aim to make it easy for real estate professionals, property owners, small business operators, and community planners to access geospatial hazard information. With our expertise in geospatial data, we aim to use our knowledge efficiently. We hope to save you some time, effort, and money.
The Problem We Solve
Critical hazard risk information is often published in formats that are difficult to understand. They require specialized GIS software and expertise to interpret. Real estate offices, property managers, and individual homeowners face a costly choice. They must either invest in expensive enterprise solutions or operate without essential geospatial information. This information gap leaves communities vulnerable and potential decision-makers uninformed.
Our Solution
Through our API-driven platform, we make hazard risk assessment as simple as inputting or uploading a location. With our most basic service: you simply provide the location and we deliver comprehensive hazard risk reports. Our core service is limited to flood based hazards right now but we are working to incorporate:
- Flood inundation and wildfire hazard assessments (core service)
- Custom upload and assessment of bulk location list (premium service)
- Conversion of geospatial data types (premium service)
- Enhancement of geospatial data -> Integration of census and hazard information into your existing GIS dataset (premium service)
Accessible Pricing for Real Impact
We believe hazard risk intelligence shouldn’t be limited to large enterprises. Our tiered approach ensures accessibility:
- Free tier: Individual location searches -> Up to 5 free reports per day with AI Flood Risk Summary
- Premium services: Bulk location processing, legacy data integration (spreadsheets, shapefiles, etc.), and custom analysis. All services are priced reasonably to reflect actual processing costs, not enterprise markup
We charge mostly where we incur significant cloud processing and storage expenses, keeping our service economical and mission-focused.
Leadership & Expertise
GEOSLN is led by experienced GIS staff with extensive background in geospatial data analysis, hazard modeling, and risk assessment methodologies. As a small business, we provide direct client relationships and provide personalized support for every project and inquiry. At GEOSLN you get a personal touch.
Service Roadmap
Our phased rollout prioritizes the most critical hazard types:
- Phase 1: Flood inundation risk analysis (launching soon-> Core free service)
- Phase 2: Global wildfire risk integration (December 2025 -> Enhanced free service)
- Phase 3: Additional hazard datasets and enhanced analytical tools (January 2025, rollout of most premium tools)
Why This Matters
In an era of increasing environmental uncertainty, understanding location-specific hazards is essential for informed decision-making. Whether you’re evaluating property investments, planning business continuity, or protecting your family’s safety, geospatial risk intelligence provides the foundation for better choices.
