GeoMapper Data Collector is application for collecting geographic information in SQLite database and recording GPS tracks with distance and duration measurement. It can be used for various outdoor activities (hiking, running, cycling, ...) with use of offline maps. With control of offline maps transparency, it can be combined either with other offline maps or with Google Maps, if internet connection is available. You can use number of GIS applications (e. g., Global Mapper (

manual in Serbian

), QGIS) to easily export any map you have and use it as overlay or base map.

NOTE: If App keeps crashing on Android 12, you need to disable notifications from Settings.

Features:

• record GeoPoint at current location, specific coordinate or location picked from map

• set user, project and number for every GeoPoint

• predefined set of mountaineering/hiking types for GeoPoint

• export recorded GeoPoints as SQLite database or in other format (

CSV
