==================    
**What it does ?**
==================

This Galaxy tool allows you to merge two data tables (tabular format only) according to their latitude and longitude coordinates (in **WGS84** projection), finding the closest points.
This tool can be used as part of the Ecoregionalization workflow data preparation that allows you to create ecoregions from occurrence and environmental data. 

===================         
**How to use it ?**
===================
        
This tool takes in input the environmental data as well as the species occurrence data. See examples of inputs below. These files must be in tabular format. You also need to select the column(s) where your latitude and longitude parameters are located in both files.
To be as precise as possible, the latitude and longitude in both files must be of the same precision.

This tool gives in output two files: 

 - Information file conataining the coordinates of occurrence data, the coordinates retains from environemental data and the distances between the two. See example below.  
 - Occurrence and Environement merge file containing occurrence data and environmental data cooresponding. See example below.
