Container
A .geov file is a PKZIP-compatible archive (binary). The local file header typically begins with the ZIP signature PK\x03\x04. The outer file MUST be handled as binary when stored or transferred.
Required members:
project.json— UTF-8 JSON project descriptor (see below).layers/— one or more*.geojsonfiles (UTF-8 JSON GeoJSON FeatureCollections, RFC 7946).
Unknown archive entries SHOULD be ignored for forward compatibility. Optional product-specific members are not part of this normative specification.
project.json
Top-level object fields:
| Field | Type | Description |
|---|---|---|
version | string | Descriptor version (e.g. 2.0). |
type | string | MUST be GeoVProject. |
name | string | Human-readable project name. |
camera | object | latitude, longitude, zoom, bearing, tilt (map view). |
layers | array | Layer descriptors (see below). |
provenance | object | Optional metadata (createdBy, packageFormat, contentType, symbologySchema). |
Each element of layers[] includes at minimum name, visible, style, and layerFile (basename under layers/). Optional symbology is defined in GEOV symbology.
Recommended provenance.contentType: application/vnd.geovirtuallis.geov+zip. Recommended provenance.packageFormat: portable-zip-v1.
Layer GeoJSON
Each referenced file MUST be a GeoJSON FeatureCollection. Coordinates use longitude, latitude order per RFC 7946. Exporters SHOULD omit implementation-internal feature property keys (names beginning with __).
Security considerations
Packages are data-only (JSON and GeoJSON). They do not execute code or escalate privileges. Importers SHOULD limit ZIP entry count and expanded size, parse JSON with bounded resources, and treat all strings as untrusted. Packages may contain sensitive location and attribute data.
Interoperability
ZIP is supported on common desktop and mobile systems. JSON members are UTF-8. The version field in project.json governs descriptor semantics; implementations SHOULD support documented versions or reject invalid packages clearly.
