GeoSpark

The Open-Source Geospatial Intelligence Protocol & Engine

Give any AI model a spatial mind. Open source. Run anywhere.

---

Current LLMs fail at spatial reasoning — achieving 0% on geodesic distance computation and ~48% (random chance) on topological reasoning across five model families in our benchmarks. GeoSpark fixes this.

The Problem

Ask any LLM: "Is the Louvre inside the 7th arrondissement of Paris?"

It will confidently guess — and get it wrong most of the time. LLMs have no geometric engine, no coordinate system awareness, and no way to verify spatial claims. They hallucinate distances, confuse containment with proximity, and silently swap lat/lon.

The Solution

GeoSpark gives AI models ground-truth spatial reasoning through a standardized protocol:

from geospark import Engine
from geospark.protocol import SpatialQuery, SpatialOperation

engine = Engine(tools=["geocoder", "terrain"])

# Geocode a location (not guessing — real coordinates)
result = engine.execute(SpatialQuery(
    operation=SpatialOperation.GEOCODE,
    metadata={"query": "Eiffel Tower, Paris"}
))

# Check spatial relationships (100% accurate, not LLM guessing)
from geospark.engine.spatial_reasoner import SpatialReasoner

park = {"type": "Polygon", "coordinates": [[[2.29, 48.85], [2.30, 48.85], [2.30, 48.86], [2.29, 48.86], [2.29, 48.85]]]}
point = {"type": "Point", "coordinates": [2.295, 48.855]}

SpatialReasoner.check_relationship(park, point, "contains")  # True — ground truth

Key Features

• Autonomous Spatial Agents — Give a goal, get a complete analysis. No manual step-by-step. Three built-in agents:
  • GeoAgent — Multi-step spatial analysis from natural language ("Find hospitals near the Eiffel Tower")
  • SpatialReport — One-command location intelligence dossier (amenities, accessibility, elevation, narrative)
  • SiteSelector — Optimal location finding with multi-criteria scoring ("Best pharmacy spot in Zurich near hospitals and schools")
• Spatial Reasoning Engine — Topology, geodesic distance, CRS transforms, buffering, area. All geometrically correct, not LLM-guessed.
• MCP Server — 6 tools for Claude Desktop and any MCP-compatible AI assistant. pip install geospark-ai[mcp] && geospark-mcp
• GeoSpark Bench — 535 benchmark questions, 5 LLM families evaluated. LLMs score 0% on distance; with GeoSpark tools, 70%. Results →
• GeoSpark Protocol (GSP) — Standardized JSON protocol for spatial queries and results.
• Pluggable Tools — Geocoding, satellite imagery (STAC), terrain/elevation with vertical datum awareness (NAVD88/EGM96/WGS84), routing, spectral indices.
• GeoSpark Flows — DAG-based workflow automation with CLI and REST API.
• Spatial Knowledge Graph — Entity-relation graph with OSM admin boundaries, BFS traversal, and natural language queries.
• Zero-Cost Stack — Local Ollama (primary, no limits) + OpenRouter free tier (fallback, ~200 req/day) + Supabase free tier (500MB). When rate-limited, GeoSpark returns clear error messages with fallback suggestions.

Quick Start

pip install geospark-ai

Autonomous Agents (the fastest way to use GeoSpark)

from geospark.agents import GeoAgent, SpatialReport, SiteSelector

# Autonomous spatial analysis — plans and executes multi-step workflows
agent = GeoAgent()
result = agent.run("Find all hospitals within 2km of the Eiffel Tower")
print(result.summary)  # "Within 2km of the Eiffel Tower, there are 3 hospitals..."

# Location intelligence dossier — one command, complete analysis
reporter = SpatialReport()
report = reporter.analyze("Federation Square, Melbourne")
print(report.accessibility)  # Nearest hospital, school, pharmacy with distances

# Optimal site selection — multi-criteria spatial scoring
selector = SiteSelector()
result = selector.find(within="Zurich", near=["hospital", "school"], facility_type="pharmacy")
print(result.best)  # Best-scoring location with explanation

As a Python library

from geospark.engine.spatial_reasoner import SpatialReasoner

# Distance calculation (geodesic, not Euclidean)
SpatialReasoner.calculate_distance(
    {"type": "Point", "coordinates": [2.2945, 48.8584]},   # Eiffel Tower
    {"type": "Point", "coordinates": [2.3376, 48.8606]},   # Louvre
)
# Returns: ~3,300 meters (actual geodesic distance)

# Spatial relationship check (ground-truth, not LLM-guessed)
SpatialReasoner.check_relationship(polygon_a, polygon_b, "intersects")

As an MCP Server (for Claude Desktop)

pip install geospark-ai[mcp]
geospark-mcp  # Starts stdio MCP server with 6 spatial tools

Add to your Claude Desktop config (~/.claude/claude_desktop_config.json):

{
  "mcpServers": {
    "geospark": { "command": "geospark-mcp" }
  }
}

Natural language spatial questions

from geospark import Engine

engine = Engine(tools=["geocoder", "terrain"])
result = engine.ask("How far is the Eiffel Tower from Big Ben?")
print(result.spatial_context.summary)
# Automatically geocodes both locations + computes geodesic distance

Tries local Ollama first (free, fast), falls back to OpenRouter.

CLI

# Autonomous agents
geospark agent "Find all parks within 2km of Big Ben"
geospark report "Federation Square, Melbourne"
geospark site-select --within "Paris" --near "metro,schools" --facility restaurant

# Spatial tools
geospark geocode "Tokyo Tower, Japan"
geospark elevation 35.6586 139.7454
geospark distance 48.8566 2.3522 51.5074 -- -0.1278  # Paris → London
geospark ask "Is Tokyo closer to Seoul or Beijing?"

Benchmark Results

GeoSpark Bench v1.0 — 535 questions across 5 benchmarks, evaluated on 5 LLM families (Qwen, Llama, Gemma, Mistral, Phi) via Ollama.

Baseline: LLM Alone (No Tools)

Benchmark	Qwen 2.5 7B	Llama 3.1 8B	Gemma 2 9B	Mistral 7B	Phi-3.5 3.8B	Mean
GeoDistance	0%	0%	30%	0%	0%	6%
GeoTopo	45%	50%	50%	50%	45%	48%
GeoChange	90%	65%	80%	85%	75%	79%
GeoReason	85%	65%	90%	75%	70%	77%
GeoMultimodal	30%	35%	30%	35%	35%	33%

With GeoSpark Tool Augmentation

Benchmark	Qwen 2.5 7B	Llama 3.1 8B	Mistral 7B	Improvement (best)
GeoDistance	70%	10%	0%	+70%
GeoReason	100%	65%	80%	+15%
GeoTopo	50%	50%	50%	+5%

Key findings:

• 0% on distance across 4/5 models — LLMs cannot compute geodesic distances from coordinates
• 48% on topology — random chance on binary questions, confirming no spatial predicate capability
• 79% on change detection — knowledge-based spatial reasoning works; the deficit is strictly computational
• 70% with tools (Qwen 2.5 7B) — tool augmentation fixes the computational gap
• 100% on reasoning (Qwen 2.5 7B) — structured prompting solves multi-step spatial chains
