Field Marker is the essential geospatial utility for viewing, measuring, and analyzing your KML and KMZ data directly on your Android device. Perfect for surveyors, farmers, engineers, and anyone needing quick, accurate field analysis, our app combines robust file handling with powerful measurement capabilities on an interactive Google Map.

Key Features
πŸ“ Accurate Measurement & Analysis
Go beyond visualizationβ€”get practical data from your files instantly:

Area Calculation: Quickly determine the precise area of any polygon feature loaded from your KML/KMZ file.

Length Calculation: Get the accurate length of line strings and polygon perimeters.

Geometry Centroids: Features like lines and polygons are automatically represented by a calculated center point (centroid) with their name, making large features easy to locate.

πŸ“ Full KML & KMZ File Support
Direct Loading: Easily open both standard KML and compressed KMZ archive files from any source (Downloads, Drive, email attachments).

Hierarchical View: Navigate your data effortlessly with a clear, collapsible list view that organizes features by Folder, Document, Placemark, Line, and Polygon.

Text Feature Handling: Ensure every feature is identifiable; we extract and display all KML tags.

πŸ“ Advanced Map Visualization
Custom Text Markers: Unlike standard pins, our markers display the feature's title rendered directly onto the icon.

Intelligent Clustering: Maintain map clarity and performance by automatically grouping dense placemarks using the Google Maps clustering system.

Google Maps Foundation: Built on Google Maps for a familiar, reliable, and high-performance viewing experience.

🧭 Location & Persistence
Quick Location: Tap the location button to instantly center the map on your current GPS location (requires permission). Your live location data is never stored or transmitted.

State Persistence: The app automatically saves your last viewed map position and zoom level, so you always resume your work exactly where you left off.

App Permissions
Field Marker requires the following permissions to provide its core functionality:

Storage/Files & Media (Read): Required to allow you to select and load KML and KMZ files from your device storage or cloud services.

Location (Fine/Coarse Location): Only requested and used when you explicitly tap the "locate me" button. This permission is required to center the map on your current GPS position. Your location data is never stored, recorded, or transmitted outside of your device. ## Rankings - #1,859,426 β€” Overall - #11 β€” marker ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_COARSE_LOCATION` - `android.permission.ACCESS_FINE_LOCATION` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.WAKE_LOCK` - `com.android.vending.CHECK_LICENSE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` - `com.yashapps.ifieldmarker.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [GPS Land Area Measure](https://chrome-stats.com/d/com.sriniapps.landmeasure) β€” 4,320 users - [Field Survey](https://chrome-stats.com/d/com.fieldmeasure.field_area_measure) β€” 210 users - [GPS Field Area Measure](https://chrome-stats.com/d/com.jsk.gpsareameasure) β€” 4,005,177 users, 3.47 / 5 - [GPS Fields Areas Measures](https://chrome-stats.com/d/lt.noframe.fieldsareameasure.adfree) β€” 10,806 users, 4.69 / 5 - [Map Marker](https://chrome-stats.com/d/com.map.marker.mapmarker) β€” 1,782 users - [GPS Field Area Measure](https://chrome-stats.com/d/gps.landareacalculator.landmeasurement.field.areameasure) β€” 232,181 users - [Field Mate: Measures & Markers](https://chrome-stats.com/d/com.rekis.fieldmate) β€” 1,162 users - [GK Field Mapper](https://chrome-stats.com/d/com.gkmobile.droid) β€” 228 users - [GPS Field Area Measurement](https://chrome-stats.com/d/com.brave.field.area.measurement) β€” 607 users - [Geotag and Measure (TM3)](https://chrome-stats.com/d/com.rizamulyadi.geotagandmeasuretm3) β€” 228 users - [GPS Field Area Measure](https://chrome-stats.com/d/com.geosurvey.fieldmeasure) β€” 231 users - [GeoKhet - GPS Area Measurement](https://chrome-stats.com/d/com.geokhet.gpsmeasure) β€” 4,313 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.yashapps.ifieldmarker)
