# Creating a vector map

## Overview

In this section, we will explain how to create Lanelet2 maps with TIER IV's [Vector Map Builder tool](<https://tools.tier4.jp/feature/vector_map_builder_ll2/>).

There are alternative tools such as Unity-based app [MapToolbox](<https://github.com/autocore-ai/MapToolbox>) and Java-based app [JOSM](<https://josm.openstreetmap.de/>) that you may use for creating a Lanelet2 map. We will be using TIER IV's Vector Map Builder in the tutorial since it works on a browser without installation of extra dependency applications.

## Vector Map Builder

You need a TIER IV account for using Vector Map Builder tool. If it is the first time to use the tool, [create a TIER IV account](<https://docs.web.auto/en/user-manuals/tier-iv-account/quick-start>) in order to use [Vector Map Builder tool](<https://tools.tier4.jp/feature/vector_map_builder_ll2/>). For more information about this tool, please check the [official guide](<https://docs.web.auto/en/user-manuals/vector-map-builder/introduction>).

You can follow these pages for creating a Lanelet2 map and understanding its regulatory elements.
