<body class='hmmessage'><div dir='ltr'>I made an experiment trying to follow this (http://www.surfaces.co.il/?p=616). I used the suggested ftools option to create the vector grid. I also made a grid using mmqgis, and just to be safe a point layer as csv. Grids are in lat lon. Points were reprojected to a custom lcc CRS (INEGI´s parameters).I loaded the Ponints in ccl, defined that I wanted on the fly reprojection in the project and these are the problems:<br><br>1)Vector grid created with ftools just touch the points at the corners<br><br>2)MMqgis grid touch the points<br><br>I wonder why is this happening, grid layers were created using the same interval (15 minutes). Following a suggestion in Stackexchange (see http://gis.stackexchange.com/questions/32353/how-to-display-both-scalebar-in-kilometers-and-grid-in-lat-long-degrees-in-quant/32359#comment43534_32359) I used the densify tool in ftools. I have the same result. The layer created with ftools is closer but do not touch the the points. <br><br>Here you can see the problems as images http://dl.dropbox.com/u/42543948/problem1.zip<br><br>here is the data http://dl.dropbox.com/u/42543948/Grids.zip<br><br>Thanks for any hint. I am using Qgis 1.8, standallone installer, win7 64bits, 8gb of ram<br><br><br>Gerardo Jiménez Delgado<br>Instituto de Investigaciones Antropológicas<br>Universidad Nacional Autónoma de México<br>Ciudad Universitaria s/n<br>Coyoacan 04510
