Prerequisites

Get the bounding box and the perimeter of the project do following the README instructions with the help of the project id which can be found in the HOT tasking manager.

Get OSM data

There is several ways to get the OSM data, so the following sub-section are exclusives.

Quick OSM (QGIS plugin)

Open QGIS and load the perimeter (this json file is a vector layer as another).

If it has done before, install the Quick OSM plugin. After installing this, a white magnifying glass on a green background will appear in the panels below the menus.

Open the plugin and put

• building as key
• Layer extend as type
• the perimeter layer as argument of the layer extend Finally run the query

The bottom of the Window show you the progress and you will have something like that at the end :

A temporary layer has been created. It is important to save as/export it in a file. Do not forget to use the nomenclature used by your team.

Repeat the operation with the other OSM tags (for example landuse, natural, water and highway).

HOT Export Tool

WARNING 1 : This solution can take a lot of time, it depends of the server loading. It can take hours !

WARNING 2 : To use this tool you need an OSM account.

Connect to the HOT Export Tool with your OSM account. It will ask after an e-mail address to say you when the export is completed.

Copy-paste the bounding box at the upper right of the page in the search bar.

At left of the page put a Name and a Project, then click on Next.

Choose the export format, shapefile for example.

Choose the tag to export (buildings, land use, natural and water for example). The best thing is to load a configuration created by your team to standardize the data.

Read the summary and choose the options. You can put nothing or just publish the export to let other people get information on the current server loading.

After creating the export, you are direct to export page. You can copy-paste this URL to consult this export later, in all case you will receive an e-mail when it was completed.
