Frequently Asked Questions

General Questions

What is TopoXY?

TopoXY is a professional coordinate conversion and terrain analysis app for surveying professionals across 6 EU countries: Romania (Stereo 70), Poland (PUWG 1992), Czechia and Slovakia (S-JTSK Křovák), Italy (Gauss-Boaga) and Germany (ETRS89 / UTM). It converts between each country's national CRS and WGS 84, provides elevation profiles and terrain analysis, plus ANCPI ortophoto and cadastre for Romanian users.

Is TopoXY free?

TopoXY is free to download with core features available at no cost. A Pro subscription unlocks unlimited conversions, removes ads, and provides access to all premium features.

What iOS version do I need?

TopoXY requires iOS 17.0 or later and is compatible with iPhone.

Coordinate Conversion

Which national CRS does each country use?

How accurate are the conversions?

Sub-centimetre for PL/CZ/SK/DE (libproj with national grids), sub-metre for RO (hand-rolled Stereo 70 Helmert math) and engineering ±1–3 m for IT (NTv2 grid not yet bundled — disclaimer is shown in the app before purchase). For official cadastral submissions, results must be verified by a licensed surveyor under each country's regulations.

Can I convert multiple coordinates at once?

Yes! TopoXY supports batch conversion. You can import multiple coordinates from clipboard and process them in bulk.

Privacy & Security

Does TopoXY upload my data?

No. All coordinate conversions and calculations happen locally on your device. Your coordinates are never stored on external servers.

What data does the app collect?

TopoXY uses Firebase Analytics for anonymous usage statistics and crash reporting. No personal data or coordinates are collected. Read our full Privacy Policy.

Can I use TopoXY offline?

Coordinate conversions work offline since all calculations happen on your device. Features like elevation profiles, terrain analysis, and map imagery require an internet connection.

Subscriptions & Payments

How do I manage my subscription?

You can manage or cancel your subscription at any time through your iPhone Settings → Apple ID → Subscriptions.

How do I restore my purchase?

Open TopoXY → Settings → Tap the support card → Tap "Restore Purchases" at the bottom of the screen.

Will my subscription automatically renew?

Yes, subscriptions automatically renew unless cancelled at least 24 hours before the end of the current billing period. You can cancel anytime in iOS Settings.

Troubleshooting

The map or ortophotos are not loading

Ensure you have a stable internet connection. Map tiles and ANCPI ortophotos require connectivity to load. Try force quitting and reopening the app.

Elevation data is not showing

Elevation profiles and terrain analysis require an internet connection to fetch data from Mapbox. Check your connectivity and try again.

The app is slow or crashes

Try closing other apps and restarting TopoXY. If the issue persists, restart your device. Make sure you're running the latest version from the App Store.

My location is not accurate on the map

Location accuracy depends on your device's GPS signal. Ensure location services are enabled for TopoXY in iOS Settings → Privacy → Location Services.
