## What is Techduto Maps?

Techduto Maps is the offline map for people who work outdoors: drainage, surveying, construction and agriculture.

Download your area before you leave. Out in the field the app keeps working with no signal at all — with your GPS position always on screen.

OFFLINE MAP OF ALL BRAZIL
A vector map of the whole country, ready to use without internet. Download only the piece you need, satellite imagery included, and work all day without a bar of signal.

OPEN THE PROJECT YOU ALREADY HAVE
Import KML, KMZ, GPX and GeoPDF. The drainage design, the survey, the field boundary map — everything shows up over the satellite image, with each feature name visible on the map. Export to KML to send to your crew or back to the office.

MEASURE DISTANCE AND AREA
Tap the map to measure right away, or walk the perimeter with GPS on. Results in feet, miles and acres — or meters, hectares and km² if that is how you work.

PINS WITH PHOTOS, NOTES AND ELEVATION
Mark the culvert, the outlet, the erosion spot. Attach photos, write your note and keep the elevation of the point. Everything stays on the device.

PRECISE POINT BY GPS AVERAGING
Stand still over the point and let the app average several GPS readings. A far steadier coordinate than a single fix.

RECORD YOUR TRACK
Turn on recording and the app logs where you walked or drove, with your own distance and time thresholds between points.

NAVIGATE TO A POINT
Pick a pin or type a coordinate and follow distance and bearing until you arrive. No mapped road required.

ALERTS WHEN YOU ENTER OR LEAVE AN AREA
Set a radius around a point and get alerted when you cross the line. Useful for preservation areas, easements and property boundaries.

PHOTOS IN THE RIGHT PLACE
Pick photos from your gallery and the app drops each one at the coordinate where it was taken, using the GPS inside the image itself.

REAL ORGANIZATION
A library with folders per job or per farm, search by name, filter by file type, and layers you switch on and off as you need them.

YOUR WAY
Decimal degrees, degrees and decimal minutes, degrees/minutes/seconds. Metric, imperial or nautical. Scale bar, marker size and colors the way you like. Search by address or by typed coordinate.

Techduto Maps is free, asks for no sign-up and keeps your data on your own device. The free plan holds up to 10 imported maps.

Built by Techduto, which does agricultural drainage in the Brazilian field every day. More at techduto.com.br.


## Version history (last 5 releases)

### 1.0.5 — 2026-09-08

You can now delete a measurement or track right on the map: press and hold it, then choose Delete shape.

A track interrupted by the system can be recovered when you reopen the app. KML export now carries altitude, color, icon and measurement data. Fixes when repositioning pins, plus performance improvements.

### 1.0.3 — 2026-08-17

Pinos com ícone personalizável e opção de arrastar para reposicionar. Melhorias na cópia de coordenadas em múltiplos formatos (UTM, DD, DMS, DDM, MGRS).

### 1.0.2 — 2026-08-16

Fixes in this version:

• Pins you create now show up properly, right where you placed them.
• Your GPS position keeps updating with an imported plan open — it used to freeze and look like GPS had dropped.
• Feature names from KML exported out of a shapefile now show on the map: every outlet and every line comes out labeled, instead of a pile of identical unnamed points.
• Creating a pin now records the elevation of the point.
• Pins now have a description field for what you saw there.
• Each distance or area measurement becomes its own item in the library, so you can find and delete them one by one.
• Fixes to deleting layers.

### 1.0.1 — 2026-07-15

Correção de imagens da ficha do app na loja.

### 1.0 — 2026-07-14

No release notes.
