Virestrom

Virestrom is a simple, automated tagging and geometry-generation tool suite designed for OpenGeofiction (OGF): Mishota.

More documentation can be found here.

Features

All tools can be accessed from JOSM's Tools menu or via their keyboard shortcuts.

---

1. Building Creator

• Shortcut: CTRL+SHIFT+A

Procedurally generates rectangular or custom geometric buildings inside selected landuse/residential areas.

• Automatically determines alignment and rotations matching nearby road ways.
• Simulates realistic building footprints based on configurable aspect ratios (e.g., standard 25ft × 60ft short-side shapes, 65ft × 30ft long-side shapes, or square/angled layouts).
• Automatically calculates and projects exact latitude/longitude coordinates based on regional meters-per-degree values.

2. Building Tagger

• Shortcut: CTRL+SHIFT+X

An interactive GUI panel that automates complex housing, apartment, and commercial tags.

• Smart Height Calculator: Input target levels, and the tool calculates randomized, realistic building heights using a variation factor (e.g., ~3.0m per floor for houses, ~3.2m for apartments, ~4.0m for commercial).
• Weighted Resident Math: Pick a target population value. The tool generates a weighted average population value around your target.
• Apartment Math: Calculates building:units automatically based on specified unit sizes, floor counts, and target residency.
• Address Sequencing: Remembers city, postcode, and street names across selections, automatically incrementing house numbers.

3. Rural Farmland & Parcel Splitter

• Shortcut: CTRL+SHIFT+Y or ALT+SHIFT+Y

Powered by the Java Topology Suite (JTS), this tool splits larger, selected polygons into smaller, divided parcels (such as rural farmlands, residential blocks, or subdivisions).

• Splits boundaries along randomly generated or structured dividing lines.
• Retains and applies logical agricultural or residential tags across the newly subdivided areas.

4. Admin Level Tagger

• Shortcut: CTRL+SHIFT+Q or ALT+SHIFT+Q

Designed to streamline the creation of administrative boundary relations (e.g., states, counties, townships).

• Allows rapid entry of boundary names, populations, administrative levels, and parent regions.
• Automatically constructs JOSM boundary relations, pre-assigning member roles like outer.
• Saves session preferences for admin_level and county so you do not have to re-enter them constantly. Saves is_in:state persistently across JOSM sessions.
• Note: Intended to accelerate basic boundary layouts. Complex multi-nested relation setups (like intricate inner-way holes) should still be verified or constructed manually.

Installation

1. Ensure you have JOSM's official jts plugin installed via JOSM's Plugin Manager.
2. Download the built virestrom-2.jar and copy it into your JOSM plugins directory.

Information on locating your system's plugins folder can be found on the JOSM Plugins Wiki.

Development & Compiling

The project compiles with Java 11. It compiles against josm-tested.jar and compiles against jts-core (which JOSM resolves at runtime via the Plugin-Requires: jts manifest header).

Compile and Package

Use the included build.sh script to clean, compile, and bundle your JAR:

./build.sh
