User guide: core logging, mapping and sampling in the field
Each chapter covers one field task: describing core by interval, loading existing drill holes from Excel or CSV, mapping with no signal, and exporting to SHP, TAB, Excel or GeoPackage to continue in any GIS. Grouped by task, most-read first.

Drill hole logging
Core description by From/To interval, logging tables from lithology to QA/QC, and loading existing holes from Excel, CSV or SHP.
Drill core logging on a tablet: strip log, intervals, charts
Log core by From/To interval with no signal: hole selector, a strip log built from your tables, and interval, symbol or chart tracks with depth zoom.
Lithology, alteration, mineralisation and QA/QC: the logging tables
Pre-loaded tables linked by Hole ID and From/To: lithology, alteration, mineralisation, structure, sampling with QA/QC, geotechnics (RQD) and photos.
Import drill hole data from an Excel or CSV spreadsheet
Load collars and From/To intervals from Excel, CSV, SHP or TAB: map the Hole ID, From and To columns and the hole selector lists every imported hole.
Data in and out
Which formats go in and out of the project (SHP, TAB, Excel, CSV, KML, Geodatabase, GeoPackage) and how to change many rows at once.
Export geological data to SHP, TAB, Excel or GeoPackage
Which formats go in and out of the project (SHP, TAB, Excel, CSV, KML, GDB, GeoPackage), per-table export filters, and a .zip with photos and audio.
Bulk table editor — update, copy and delete data in batches
How to update, copy or delete many rows of a table at once: the bulk editor's three modes, their recipes and the preview before applying.
Surface mapping
Map, layers and rasters with no signal, basemaps downloaded before the trip, digitising contacts and structures, and styles by grade or lithology.
Offline geological mapping: map, layers and layer memories
How the surface mapping module works with no signal: the layer menu, layer memories and groups to organise your project.
Vector layers, rasters and WMS basemaps in the field
Load vector tables, drone imagery, DEMs and WMS/WMTS/XYZ basemaps, and use them offline during the campaign.
Download maps for no-signal work, filter and label your data
Download map areas by zoom for campaigns with no coverage, SQL filters over tables, and feature labelling on the map.
Digitising contacts and structures: drawing, GPS and geometry editing
Freehand stylus drawing over imagery, GPS-traced geometries, magnetic snap, and union, intersection and DEM-intersection operations.
Dynamic styles: colour samples by grade and lithology by unit
Point, line and polygon styles, plus SQL-condition dynamic styles to see geochemical grades or lithology classes right on the map.
Data consistency
Code lists, required fields and structure measurement with the device's sensors (geocoders), so every geologist records data the same way.
Getting started
Which Android device you need, how to install and activate the app, with a 20-day trial, and how a project is organised on the tablet.
Field Manager requirements and compatibility
What your Android device needs to run Field Manager — minimum version, sensors, stylus, external GPS and RTK, and which file formats it supports.
Install and activate Field Manager
How to create an account, get a subscription or start the free trial, and download the app from the platform to install and activate it.
Geology data on the tablet: projects, templates and backups
Each project is one folder with a SpatiaLite database: works with no signal, starts from a template, and backs up daily or to a .zip with photos and audio.
Settings and support
Projection, GPS source, minimum capture accuracy and RTK corrections over NTRIP; app version, support code and help.
Preferences: projection, GPS source, stylus and capture accuracy
Full reference of Field Manager settings: projection system, GPS source, minimum capture accuracy, stylus support and absolute snap.
Support window: version, support code and help
The screen where you download the manuals, check for an update, report a bug and manage the device's subscriptions.
What is core logging: drill hole and field mapping glossary
What core logging is and what RQD, collar, downhole survey, From/To, Hole ID, lithology, alteration and QA/QC mean, with how each one is recorded.
