The Problem
A field team collects GPS coordinates and needs to show a client the results by end of day. The options: install QGIS (30-minute learning curve), spin up a Mapbox account (API keys, billing), or email a raw file nobody can open. Sharing one map should not take longer than making it.
The Solution
MapDrop eliminates every step between having a GeoJSON file and having a styled, shareable map. Drag the file onto the page, pick colors and a basemap, hit share. The recipient opens a link and sees the styled map instantly — no account, no install, no API key on either side.
Feature Deep Dive
Every part of MapDrop is designed for speed and simplicity, from the drag-and-drop uploader to the one-click share links.
Drag & Drop Upload
Drop any GeoJSON file up to 10MB directly onto the page. Parsed, validated, and rendered on the map in under 2 seconds with automatic viewport fitting — so you see your data immediately, not a loading spinner.
Interactive Style Editor
Customize fill, stroke, opacity, line width, and point radius with live preview. Color-by-property with categorical palettes turns raw data into presentation-ready maps — no GIS expertise needed.
Multiple Basemaps
Switch between light, dark, satellite, and streets basemaps to match context — satellite for field work, light for presentations, dark for dense point data. One click to change the entire feel of the map.
Shareable Public Links
Every styled map gets a unique public URL. Recipients see the exact styled map without creating an account or installing anything. Edit tokens let the creator update styles after publishing without breaking the link.
