01 — IMPORT
Open a spatial file
Start directly from GIS files already used in office or field workflows.
Lightweight field GIS viewer
Display your spatial data,
wherever you go.
Open GIS data in one click.
Geoplacer is a lightweight mobile GIS viewer for quickly opening and checking spatial data during field work, site visits, and everyday GIS workflows.
Core workflow
Open a file. See it on the map.
02 — ORGANISE
Keep related data together
Use simple folders for projects, surveys, or site visits.
03 — VIEW
Inspect it on the map
View layers and perform lightweight mobile GIS checks without desktop GIS complexity.
Formats and map
Built for the files you already have.
Supported GIS formats
Geoplacer can import and display these formats when the file is structurally valid and within current app capabilities. It does not fully support every GIS file.
GeoJSON
.geojson, .json — vector read and map display
GeoPackage
.gpkg — vector feature tables; some CRS values are converted to WGS84 for display
GeoTIFF
.tif, .tiff — georeferenced raster display when Geoplacer can read the file
KML
.kml — Placemarks and local GroundOverlay images; remote image URLs are not fetched
KMZ
.kmz — unpacked on device, then read as KML, including local overlay images in the archive
If a file is valid but not something Geoplacer can display yet, the app says so instead of pretending the import succeeded. Some additional GIS formats may import when they can be read safely.
Map-first, not toolbar-first
The workspace stays map-first, with compact Layers, Locate, and Draw controls. Geoplacer is a field viewer, not mobile QGIS.
Local-first where possible
Your spatial data should stay under your control.
Geoplacer copies imported files into on-device app storage and does not require an account. The map still needs a network connection to download OpenStreetMap basemap tiles. Location is used on the device when you ask to be shown on the map.
