moLoServ Rust

moLoServ is the name for morihofi's Location Service. Fully written in Rust, previously in Java and later Go. It contains multiple components, see below

Map Renderer

We offer two versions, based on the almost same codebase

Server side Rendering

The classic one that is at least supported since the older WiFiDB Java releases. It serves a OpenStreetMap compatible HTTP API for overlay tiles and Google Earth API support.

Client side Rendering (Beta)

A newer option besides the SSR renderer that lets the browser rendering the overlay using same data. It uses Rust compiled to WebAssembly to achieve almost same performance

API

The API offers Google compatible GeoLocation and Scan Uploads

Util

The main command that takes all the measurements and produces the grid container, that can then be passed to the API Server or the map renderers

Grid container schema

Each grid JSON entry now optionally contains a bluetooth object in addition to wlan and cellular.

Logging

All binaries respect the MOLOSERV_LOG_LEVEL environment variable. Accepted values are TRACE, DEBUG, INFO, WARN and ERROR. If the variable is unset, the log level defaults to INFO. Providing an invalid value falls back to DEBUG.

Offline OSM Data

Operations that rely on OpenStreetMap require .pbf files to be downloaded and cached locally. The utilities read from these local files and never fetch data from upstream OSM servers at runtime.
