Web app
Elkins in 3D
Every mapped building in Elkins, West Virginia, standing at a height measured from 2018 lidar rather than guessed. Tilt and rotate to read the town's shape. Colour repeats the height so the map still reads looking straight down. Click any building for its height and where that height came from.
Web app
Twenty-five years of West Virginia water quality
1,175 monitoring sites and 285,788 measurements from the gas counties of north-central West Virginia, 1995 to 2019, each reading compared to its published drinking water limit. The counters and charts follow the map: pan or zoom and every number re-answers for what is on screen. Source: WVU GIS Technical Center / EPA water quality project.
Web app
Randolph County Storm Events Dashboard
Thirty years of severe weather in Randolph County, West Virginia: what happened, when, and what it cost. Built from the storm events data layer with indicator and chart widgets; it is an ordinary web app and can be edited like any other.
Web app
Randolph County Bridges Dashboard
Condition, age, and size of the 188 highway bridges in Randolph County, West Virginia. Built from the bridges data layer with indicator and chart widgets; it is an ordinary web app and can be edited like any other.
Open source GIS portal
A self-hosted portal, a field PWA, and QGIS
GratisGIS is for teams that want their data on their own hardware and want out of ArcGIS Online seat licenses. What is credible today is the portal, sharing, field collection, and QGIS. It is not a full ArcGIS Online replacement, and it is not a drop-in for Experience Builder, Survey123, Field Maps, or enterprise identity depth. Built on open components (PostGIS, MapLibre, Keycloak). No license fees; your only cost is the hardware (or cloud bill) you choose to run it on.
Dashboards ship as web-app layouts (KPI Dashboard and Operations Board). Dedicated document report templates are not built. Tool recipes exist; a node-graph builder does not.
Self-hosted on your own hardware
PostGIS-backed datasets, web maps, and forms; bring data in from shapefiles, GeoJSON, GDB, or any OGR-supported format. Docker compose, single-command deploy, runs on a $20/month VPS. No license fees, no SaaS lock-in.
First-class QGIS support
An official plugin in the QGIS plugin repository: browse and search the portal, publish layers and whole projects from the canvas, take a layer to the field, and sync edits back. No plugin? Rasters appear in QGIS's built-in catalog browser and layers open over standard APIs, with an API key for private content.
Field-ready PWA
A data-collection app that installs to the home screen, works offline, and syncs when you're back online.
Works with the tools you already use
OGC API Features, Tiles, Styles, and Records; a STAC catalog; CSW 2.0.2; Schema.org JSON-LD; WMS / WFS service references. WebMap JSON export points at the portal's own layer URLs. Whether ArcGIS Pro, ArcGIS Online, or QGIS open that file depends on the importing tool. Importing a WebMap JSON file keeps FeatureServer URLs as live references; copying hosted features into the portal is a separate stage step.
Operational features the portal ships with
Housekeeping that runs itself
Stale items get flagged. Inactive users get auto-disabled. Expiring shares trigger warnings. Spatial extents get recomputed on a schedule. Admins get a dashboard, not a backlog.
Sync that doesn't lose your work
Offline edits go to a per-edit queue with isolated retries. A bad row doesn't poison the rest. Schema changes notify every device that has cached the deployment so the field crew rebuilds before they next sync.
Email notifications you actually control
Built-in templates for shares, expirations, schema changes, form submissions, and field captures. Org admins customize the copy through a guided editor with click-to-insert variables. Routed through one SMTP, not a sprawl of webhooks.
Sharing granularity that makes sense
Share an item with a user, a group, or a folder. Folder shares cascade to every item in the folder. Per-share row scope ('all' vs 'own') and geographic clip (polygon) layer on top. View / download / edit / admin tiers, not a single 'shared' bit.
What's new
- Admin Updates page
Signed-in admins get an Updates page that compares this install with GitHub and lists backup and restart steps. It does not update Docker for you.
- Showcase dashboards on Load sample
Load showcase dashboards adds the public demo's storm-events and West Virginia water-quality dashboards plus Elkins in 3D, each with fresh ids for your install.
- Add layer works on plain HTTP NAS
Opening GratisGIS at `http://` on a LAN address (typical TrueNAS) no longer breaks Add layer, Add group, or drawing. Failed layer creates also show the server reason.
- Install on a home NAS
Paste one compose file into TrueNAS or Dockge; the first boot writes secrets and prints the LAN address and admin password. Listens on 8080 by default so your NAS UI can keep 80/443. Optional Tailscale, Cloudflare Tunnel, and public-domain modes are in the TrueNAS guide.
- Live markup with a teammate
When you and a signed-in teammate both edit the same markup set on a map, new pins and sketches show up for each other without overwriting. Anonymous markup still saves the older way.
