The Platform

Everything cave data needs.

A full-featured research platform built specifically for how cavers actually work — in the field, offline, and across organizations.

20+ map layers. Your data on top.

The map is the center of the platform. Topo quads, karst geology, LiDAR hillshade, land ownership, sinkhole databases — stack as many layers as you need. Overlay your own GPX tracks, draw areas of interest, and view every cave you have access to.

USGS topographic quads (current + vintage)
LiDAR hillshade and bare-earth
Karst geology overlays
Land ownership and management
State karst GIS databases
Sinkhole density layers
Satellite imagery
Custom GPX/KML overlays
Draw polygons and areas of interest
Dynamic legend based on visible data
Historical USGS topo quad browser

Upload a report. Get every cave out of it.

The extraction pipeline reads your uploads and pulls out every cave name, coordinate, depth, length, species observation, and person name it finds. PDFs, scanned documents, trip reports, survey bulletins, CSV files, shapefiles, KML — all processed automatically. Results are flagged for human review before being linked to site records.

Supported Formats
PDF (including scanned)
Word documents (.docx)
CSV and Excel
KML and KMZ
GPX tracks
Shapefiles
HTML pages and URLs
Survey files (Compass .dat, Walls .srv, Therion .th)

Just describe what you're looking for.

No query syntax to learn. Type what you mean — the platform figures out the rest.

"caves deeper than 200ft in Eddy County"
"karst springs in the Ozarks with survey data"
"sites visited by John Smith"
"unverified caves in my region added this year"

Works without cell service.

Install The KEEP on your phone as a web app. Sites, documents, and photos cache locally so you can pull up a field card at the entrance with no signal. Log observations with GPS autofill — coordinates, photos, notes. Everything syncs when you get back in range.

Install as PWA (no app store)
Sites and PDFs cached locally
GPS coordinate autofill
Camera capture for photos
Offline write queue with sync on reconnect
Works on any device (iOS, Android, desktop)

Describe a cave the way cavers describe it.

The classification system covers everything from genesis type to surface morphology to condition flags — aligned with UIS and ASTM D8512-23 standards.

Genesis types
12 categories — solution, lava tube, sea cave, talus, and others
Passage morphologies
20 types describing cross-section, floor, and passage character
Surface feature types
22 categories for karst surface expressions
Access conditions
Gated, permit required, seasonal closure, landowner permission
Hazard flags
Flood risk, breakdown, hydrogen sulfide, WNS positive
Verification status
Unverified, field-confirmed, survey-confirmed
Special designations
Archaeological, paleontological, hydrological

Get your data out in the format you need.

Every export is scoped to your access level. Sites you can't see aren't in the file. All exports are audit-logged.

Format Use case
CSV Spreadsheet analysis, GIS import
KML / KMZ Google Earth, mapping apps
GPX GPS devices, navigation apps
GeoJSON Web maps, PostGIS, QGIS
PDF field cards Print-ready site sheets for the field
Compass .dat Carlsbad Cavern-compatible survey format
Walls .srv Walls survey software
Bibliography PDF Formatted reference list of sources

Add a cave once.
Get everything we know about it.

When you enter a cave or upload a document, The KEEP cross-references it against 121 external databases, every uploaded document, and every existing site record — automatically. Different name, slightly different coordinates? It still finds the match.

Step 1

You add data

Enter a cave name and coordinates, upload a PDF trip report, import a GPX track, or drop in a scanned survey map.

Step 2

The engine matches

Fuzzy name matching, proximity search, and automated confirmation finds connections across sources. "Bear Hollow Cave" matches "Bear Hollow Cavern."

Step 3

You get context

Every source that mentions the site — linked. Depth from a 1987 newsletter. Coordinates from a 2003 USGS report. Your 2024 GPS reading. All together.

Nothing gets overwritten. Every claim keeps its source, author, and date. The full history is always there.

Cross-referenced against hundreds
of external sources.

When you add a cave, The KEEP automatically cross-references it against a large catalog of external cave registries, scientific databases, state GIS sources, international registries, and publication archives. No manual lookup required.

Scientific Databases

Major biodiversity, occurrence, and open-access scientific repositories covering species observations, geological surveys, and academic publications.

State & Regional GIS

State karst inventories, sinkhole databases, and ArcGIS/WMS sources from agencies across the US — automatically queried by location.

International Registries

Cave registries from over a dozen countries, covering hundreds of thousands of documented caves across Europe, Latin America, and beyond.

Cave Organizations

Data from regional and national caving organizations, survey groups, and cave research foundations — aggregated and de-duplicated.

Specialized Archives

Cave diving registries, bat and biota databases, speleothem records, specimen collections, and incident archives.

Publications & Literature

Karst journals, historical expedition reports, cenote databases, and deep-web publication archives going back decades.
