GeoField — Browser-Native Geospatial Toolkit
Browser-native geospatial toolkit — field calculator, geometry simplifier, and format converter. Zero accounts, zero uploads, data never leaves your machine.
The Challenge
GIS professionals need simple operations but existing toolbox is fragmented. Desktop GIS is overkill, CLI tools are intimidating, online converters are privacy dealbreakers.
Our Approach
Core Tools: Field Calculator (live preview), Geometry Simplifier (teal overlay animation), Format Converter (7 output formats). Visual Language: "Field Paper" — warm off-white + survey-orange accent, topographic grid pattern, geometric display face + clean sans-serif. Privacy: No install, no login, works offline. No file ever leaves the user's machine.
The Results
A fully open-source tool that replaces desktop GIS for common data-wrangling tasks. Supports 7 geospatial formats, 40+ field calculator functions, 2 simplification algorithms with live preview, and 5 data tools — in a browser tab.
