sing·kap·announ · IndonesianAn outcrop. The place where rock breaks through the soil and can finally be read.
From the first outcrop to the finished geological map.
Record stations and readings with no signal, watch each one land on the map, and compile a sheet you would be proud to publish.
01 · Walk the ground
Open the project at camp, walk out with the map on your phone, and record as you go. Three surveyors, three traverses, one map. Nothing gets retyped in the evening.
Offline map package · GPS position and accuracy · photos, sketches and samples on every station
02 · Read every outcrop
Strike and dip go in with the right-hand rule, and every reading drops onto a stereonet the moment you save it. You can watch the fold take shape while you are still standing on the ridge.
Bedding · joints · foliation · lineation · equal-area net, lower hemisphere
03 · Let the map emerge
Assign stations to units, draw contacts that snap to your observations, and let Singkapan check that every polygon closes. Contacts bend through the valleys the way the rule of Vs says they should. You stay the geologist. It does the drafting.
Unit legend · certain, approximate and inferred contacts · topology checks
04 · See what lies beneath
Draw a section line and see the fold, the fault and the granodiorite stock in profile, built from the same readings you took in the field.
Section A–A′ · readings projected onto the line · no vertical exaggeration
The problem
A mapping season produces hundreds of stations, a thousand readings and a notebook full of sketches. All of it gets copied at least twice before it becomes a map: into a spreadsheet at camp, then into GIS back at the office. Every copy is a chance to lose a decimal, a page or a week.
Nine beds · every record copied twice
Three beds · every record entered once
Like any measured section, the oldest bed is at the bottom. The thinner column is the point.
What's inside
Every geological map carries a legend, so the product gets one too. Units are grouped by where you use them. The italic note says when each one arrives.
Stations, lithology, attitudes, samples, photos and sketches in one record. Made for one hand, wet gloves and full sun.
Topography, elevation and imagery for your field sheet, downloaded at camp. The map keeps working after the last bar of signal is gone.
Every reading plots the moment you save it. Rose diagrams and fold-axis estimates come straight from your own data.
One project and one legend for the whole camp. Give each geologist a field sheet, and station numbers never collide.
Assign stations to units in bulk, draw contacts that snap to your observations, and close polygons without slivers.
Gaps, overlaps, open contacts and stations that disagree with their unit are flagged on the map before a reviewer finds them.
GeoPackage, a styled QGIS project, shapefile or CSV, whenever you want them. Your season stays yours.
Legend, scale bar, north arrow, cross-section and title block, laid out the way a survey sheet is.
Solid where a record has synced. Dashed where it is still waiting for signal.
Right-hand rule by default, plotted on the map as you save. Quadrant notation is one setting away.
When two people edit the same contact, Singkapan keeps both versions and asks you to choose. Nothing is overwritten quietly.
Try it
This is the reading screen from the field app, running in your browser. Drag the pole across the net and the plane follows. Press save and it joins the day's readings.
Equal-area, lower hemisphere, with poles and great circles. Every reading plots the moment you save it.
Take the reading with your Brunton or Silva and type it in. On Android, the phone's own sensors can offer a quick second opinion.
Strike, dip and dip direction sit side by side, so nobody argues about which quadrant a reading was in.
Location, time, surveyor and photos travel with every measurement, all the way into the compilation.
Built here
Young volcanic rock, deep weathering, heavy rain and no signal past the last village. Singkapan is being built and tested here first.
Indonesia crosses nine UTM zones and the equator. Each project is pinned to one zone, north or south, and every measurement is computed in it.
From Aceh to Papua, north and south of the equator. Set the zone once when the project starts.
Switch the interface any time. Unit names and field notes stay exactly as you wrote them.
Load DEMNAS elevation and RBI topography, or georeference the scanned sheet your lecturer handed out.
Kebumen, Central Java. Mélange, pillow lava and radiolarian chert, on ground that generations of students have mapped.
Roadmap
Read it like the chart on any map sheet. The youngest units sit at the top, and the wavy line marks where we stand today.

Yes. The whole app runs offline, the map included. Records wait safely on your phone and sync when you are back in range, and the app always shows what has synced and what has not.
No app store. Singkapan runs in the browser on your phone, tablet or laptop, and adds itself to your home screen for offline use.
Keep your compass. Typing the reading in is the main path on every phone. Android phones can offer a sensor check, but iPhone browsers do not share the compass, so there your instrument does the work.
You do. Export everything to GeoPackage, a styled QGIS project, shapefile or CSV at any time, and take it wherever you like.
Yes. Sign in with Google, invite your team, and give each person a field sheet and a block of station numbers. Leads, geologists, surveyors and viewers each see what they need.
The first field trial runs in Karangsambung, Central Java. Join the list below and we will write when a place opens.
Early access
We are looking for field camps, thesis students and survey teams with a real season ahead of them. Tell us how you map, and we will be in touch when the field trial opens.
