Why these tools exist
Maps for the Rest of Us
Nobody wakes up wanting to master GIS software. But plenty of people wake up wondering: "How much land is in this plot?" "What's the straight-line distance between these two addresses?" "Where can I charge my EV before the battery dies?" These tools bridge the gap between "I have no idea where I am" and "I need to hire a consultant."
Built for Real Life, Not Classrooms
Drop a pin. Draw a circle. Upload a CSV of coordinates from your phone. Watch your hiking route appear with elevation charts that actually make sense. No semester-long course required — just answers to the questions you actually have.
The Small Joys of Clarity
There's something genuinely satisfying about converting scribbled coordinates into a real street address, or watching a spreadsheet of GPS points bloom into a shareable map. The timezone map that finally explains why your colleague is always early or late to calls. The solar angle calculator that might actually save you money.
Made by People Who Remember Frustration
The GPX viewer doesn't demand you learn what "GPX" even stands for — just drag, drop, and go. The area calculator handles your weird, lopsided polygon. The geocoder finishes your address as you type. Even the elevation tool's honest note about its 90-metre resolution feels refreshingly human: "It's approximate, but it's free, and it'll get you close enough."
Your Data, Your Way
Export as GeoJSON. Download as JPG. Take your shapefile and run. No vendor lock-in, no "upgrade to Pro" prompts, no sense that you're renting access to your own information. In an age of subscription fatigue and platform dependency, that kind of generosity stands out.
All 33 tools run entirely in your browser — no account, no installation, no cost. Pick the one that answers your question today.
