Hello,<br><br>Thank you for your fast reply, but I am not able to send you the file, it is confidencial. But I know a way ti deviate this problem.<br><br>I have three layers:<br><br>- the limits of my country (Portugal)<br><br>- occupation polygons of where are the fields that the company owns<br><br>- polygons with climate characterization<br><br>I need to split the country in three parts (for example) and do the intersection of the occupation layer with the climate characterization layer. If I do this intersection with the hole country, it takes hours to process that amount of information but i don't know how to split the country in three and process that information separately. Important also is this seperation to be done without taking the chance of spliting any polygon.<br><br>If you could help me with nthis matter I would appreciate it very much, if not, thank you the same:)<br><br><br><br> <br /><hr />Windows Live: Keep your friends up to date <a href='http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/social-network-basics.aspx?ocid=PID23461::T:WLMTAGL:ON:WL:en-xm:SI_SB_1:092010' target='_new'>with what you do online.</a></body>
