Introduction

Many geographical datasets, municipal boundaries, and project site plans are locked inside PDF files, making them difficult to use in modern mapping applications. Our PDF to GeoJSON Converter allows you to extract vector coordinates and spatial geometry directly from your documents. Whether you are building an interactive web map or conducting spatial analysis, this tool transforms static document “drawings” into actionable geographic data.

What is this Tool?

This tool is a specialized spatial utility that parses the vector paths (lines, polygons, and points) within a PDF and translates them into the GeoJSON standard. As part of Sufyan Arman’s “Vision 2030” project at Creshy, we prioritize the security of your sensitive project data. All coordinate extraction happens locally in your browser—your maps and plans are never uploaded to our servers.

Why Use This Tool?

Manually digitizing a PDF map in GIS software is a slow and tedious process. This tool automates the extraction of geometry, allowing you to quickly move from a document to a live map layer. It is perfect for developers working with Leaflet.js, Mapbox, or Google Maps who need to display custom boundaries or paths found in official reports.

Common Problems Solved

• GIS Interoperability: Bridges the gap between traditional PDF reports and modern web-mapping technologies.
• Manual Digitization: Saves hours of “tracing” over PDF backgrounds to get coordinates.
• Coordinate Extraction: Converts document-space coordinates into a structured JSON format for easy programmatic use.

Features & Benefits

Key Features

• Path-to-Polygon Conversion: Automatically detects closed loops in your PDF and converts them into GeoJSON Polygons.
• Metadata Preservation: Attempts to keep labels and basic attributes associated with the geometry.
• 100% Client-Side: Your proprietary site plans and infrastructure maps stay on your machine for maximum privacy.

Benefits for You

• Developer Friendly: Get a clean JSON output ready to be dropped into your JavaScript code.
• Zero Cost: Professional-grade GIS conversion provided for free by DIHOD Software House.
• No Software Required: Perform complex spatial extractions without needing QGIS or ArcGIS installed.

How to Use: Step-by-Step Guide

1. Select Your PDF Map: Click “Choose File” and upload the vector-based PDF containing the boundaries or paths.
2. Process Geometry: Press the “Extract GeoJSON” button. The tool will scan the document for vector coordinates.
3. Download: Your .geojson file will download automatically once the conversion is complete.
4. Map Integration: Upload the file to your GIS software or use it in your web-mapping project.

FAQ (Frequently Asked Questions)

Q: Does this tool provide real-world GPS coordinates (Lat/Long)? A: The tool extracts the relative coordinates from the PDF. If your PDF is “georeferenced,” the coordinates will be accurate. If not, you may need to apply a “scale and shift” in your GIS software to align it with a global map.

Q: Can it extract data from a scanned paper map? A: This tool is optimized for Vector PDFs (exported from AutoCAD, ArcGIS, or Illustrator). Scanned maps are images (pixels) and do not contain the mathematical coordinate paths required for GeoJSON.

Q: Is it compatible with Mapbox or Leaflet? A: Yes! The output is a standard GeoJSON file, which is the native format for almost all modern web-mapping libraries.
