Bounding box case for Linux

The default cases for OSM and BDTOPO v2.2 are presented in other pages. Please make sure that the default cases are running on your computer before using the bounding box method.

In the default case, the area of interest is specified using a city name. You also have the possibility to calculate all the GeoClimate outputs inside a given rectangle (i.e. a bounding box).

The only difference with the default case is that geographic coordinates replace the city name. All the other elements of the configuration file remain unchanged.

The coordinates of the bounding box are expressed as [minY, minX, maxY, maxX].

Bounding box method with OSM

A bounding box has been determined for the city of Pont-de-Veyle, with the following coordinates : 46.257330,4.870033,46.269970,4.905224

The configuration file below uses this bounding box method with OSM.

In order to determine the coordinates of your bounding box, you can use the bboxfinder website. Make sure your coordinates are in latitude / longitude ("Lat / Lon") format. You can choose the coordinates options on the bottom right of the bboxfinder website.

Bounding box method with BDTOPO v2.2

The configuration file below uses a bounding box method with BDTOPO v2.2.

This bounding box represents the envelope of the city of Redon.

Note that the EPSG code for the projection system here is 2154 and not "Lat / Lon" anymore.
