## What is Kocaman Pro?

Geospatial engineering calculations for surveyors and land surveying professionals. Record, stake out and measure areas with GPS in the field; run high-precision coordinate transformations at the office.

GPS MODULES
■ Detailing with GPS — record positions from your device's GPS sensor in ED50 and ITRF96, in 3- and 6-degree zones.
■ Stakeout with GPS — navigate to a target coordinate with compass and map guidance.
■ Area Calculate with GPS — walk the boundary to compute area and perimeter.
■ Open Project with GPS — view your DXF, Shapefile and KML drawings over satellite imagery and plot your points on top.

CALCULATION MODULES
■ Bearing and distance, angle and distance, polar stakeout
■ Side point, waypoint, station and offset calculation
■ Simple curve calculation
■ 2D coordinate transformation — similarity transformation from two common points
■ WGS84 ↔ UTM and WGS84 ↔ ED50 UTM transformations
■ Official tolerance calculation
■ Degree conversion (degrees, gradians, radians)

COORDINATE SYSTEMS
■ Türkiye: ITRF96 and ED50, in 3- and 6-degree zones
■ Global: search and use thousands of systems from the EPSG dataset
■ When opening a Shapefile, the coordinate system is detected automatically from the PRJ file

DATA EXCHANGE
■ Import: CSV, DXF, Shapefile, KML/KMZ
■ Export: CSV, DXF, Shapefile (ZIP), KML/KMZ and text report
■ Share your projects by message, e-mail or cloud storage

DEVICES AND LANGUAGES
■ iPhone and iPad — full resolution and landscape use on iPad
■ 12 languages: Turkish, English, German, French, Spanish, Italian, Portuguese, Russian, Arabic, Japanese, Korean, Chinese
■ Right-to-left layout support, including Arabic

ABOUT ACCURACY
All transformations performed by the app are high-precision calculations. However, the accuracy of the result is limited by the accuracy of the WGS84 geographic coordinate your device receives from the satellites: a transformation cannot produce an output more precise than its input. Today, neither handheld GPS units nor the GPS sensors in mobile devices can deliver sub-metre positions directly from satellites. For this reason, Kocaman Pro is recommended for general positioning work rather than high-precision positioning work.

## Frequently asked questions about Kocaman Pro

### What is Kocaman Pro used for?

Kocaman Pro is used for performing positional engineering calculations and converting GPS location data into UTM coordinates for field operations like data acquisition and area calculation.

### What coordinate systems does Kocaman Pro support?

Kocaman Pro supports conversion to 3 and 6-degree UTM systems, providing ED50 and ITRF coordinate values.

### How accurate are the UTM coordinates generated by Kocaman Pro?

The UTM coordinates are derived from the device's GPS sensor and are consistent with the accuracy of the raw WGS84 geographical coordinates obtained by the device. For highly precise work, it's recommended to consider the limitations of mobile GPS sensors.

### What devices is Kocaman Pro compatible with?

Kocaman Pro is available for iPhone and iPod devices.

### How much does Kocaman Pro cost?

Kocaman Pro is a paid application priced at $4.99.

### When was Kocaman Pro last updated?

Kocaman Pro was last updated on September 30, 2024, with version 1.92.

### What is the age rating for Kocaman Pro?

Kocaman Pro has an age rating of 4+.

### Does Kocaman Pro have ads?

No, Kocaman Pro does not contain advertisements.
