Kaart: JOSM Download and Optimization

Introduction

JOSM, Java OpenStreetMap, is an advanced desktop OSM mapping editor. It has various customization abilities and tools that make mapping easier and faster. These guidelines provide a foundation, but you are free to personalize your appearance settings and toolbars to optimize your workflow. However, we advise against modifying the hotkeys so you can learn the basics.

Prerequisites

You will need:

• An OSM account

Skill Instruction

Initial Setup

JOSM is most useful when the settings are set to support your editing. The following are the recommended JOSM settings.

Navigating JOSM Preferences

In order to navigate the installation/update process, it is important to know where to find the options you need to access.

At the top of the screen you will see several buttons:

This is where you will find preferences/settings, imagery, new data layers, and many of the other functions of JOSM you will be using. The most important of these for JOSM installation, update, and set up is Settings which can be found under the button that says JOSM or opened using the hotkey CMD + , / Ctrl + ,.

The settings menu has a navigation sidebar that will help you find many of the other options you will need to access during the setup and updating of JOSM. As you go through this setup process, there may be instances where the program tells you that it needs to restart in order for some settings to take effect. It is okay to restart the program as many times as needed.

Available Settings:
	Display		OSM Data		GPS Points		Colors		Language
	OSM Server		Proxy		Map Projection		Map Paint Styles		Tagging Presets
	File Backup		Plugins		Toolbar		Audio		Keyboard Shortcuts
	Data Validator		Remote Control		Imagery		Advanced Preferences

Remote Control

To load task from a tasking manager like HOT TM or Maproulette into JOSM, we have to turn on the Remote Control.

• Press Ok to accept the changes

OSM Login

• Open Settings
• Select the OSM Server tab
• Select Use OAuth 2.0
• Select Authorize now (Semi-automatic)
  • Follow the prompts

Expert Mode

Expert mode enables us to perform more than the basic functions of JOSM. This is one of the first things we do when setting up JOSM for the first time.

• Open Settings
• In the bottom left corner select Expert Mode
• Select Ok to accept the changes

You can also enable expert mode by:

• Click View

  • Remember dialog geometries
  • Use native file choosers
  • Intermediate steps between native resolutions
  • Zoom steps to get double scale (adjust from 1 to 5)
• Select Ok to accept the changes

Toolbars

If you want to reduce clutter on your screen, you can remove the supporting toolbars:

• Click View
• Uncheck the Toolbars(optional)
  • These sit at the top and left sides of JOSM.

If you want to add/remove tools on the main toolbar, you can customize them in Settings.

• Open Settings
• Open the Toolbar tab or right click on a blank space on the main toolbar and select Configure Toolbar.
• Modify your toolbar. Current tools are on the left and available tools are on the right.
  • Recommended tools include:
    • Satellite imageries you use
    • Commonly used Tools
    • Tools specific to the project you are working on

Keyboard Shortcuts

JOSM has standard keyboard shortcuts for each tool, but also lets you create/customize shortcuts.

To do this:

• Open Settings
• Open the Keyboard Shortcuts tab
• Search for a specific hotkey you wish to change/create to see if there is a tool associated with it.
  • If you want to change an existing hotkey deselect Use default and then select Disable.
    • Use the available tools to create a new hotkey for that tool.
  • If you want to create a custom hotkey:
    • Use the available tools to create a new hotkey for that tool then assign it to your tool.
• Select Ok to confirm the changes

A list of keyboard shortcuts can be found here.
