Hello, I have a 1 degree polygon grid of the world and would like to: 1) break the 1 degree grid down to a .5 degree grid, 2) create a .5 degree grid from scratch, or 3) download a .5 degree grid that is already created. Does anyone know how I can either make one or where I can download one from? Thanks, Matt

Hello, I have a polygon layer of countries and a tif raster file of global elevation; when I run zonal statistics as a table, all of the polygons get statistics except for the polygon that represents New Zealand; does anyone have anyway to fix this or something else I could try to get the statistics I need for this polygon? Thanks, Matt

Hi, I saved a text file of all of my rubbersheeting points (now identity links) that I created with one shapefile. How do I import those to another shapefile, so it will lay right on top of the other shapefile? Thanks, Matt

I never had it in ArcGIS; the data/maps were given to me in svg format (possibly made in Photoshop), hence the reason I am trying to convert it from svg to ArcGIS. Nevertheless, I always appreciate tips!

Hi John, The svg file didn't have any spatial information in it when it was converted to CAD and it was never digitized since it was never a raster. The svg (scalable vector graphics) file preserved the country borders as polylines, and I then built the polygons from the polylines, hence they don't have spatial reference data. I'm looking for a way to input the coordinates of the countries shapefile so that they can overlay current boundaries.

Hi Anthony, Thanks for your response; I should maybe have explained a little more about my countries shapefile. the layer is of historical countries that I converted from an svg picture file into cad and than converted into a shapefile. So it didn't have any spatial reference info other than the svg file was drawn in winkel-triple projection. I do have a excel file with coordinates of the individual countries but not for the whole shapefile. Any thoughts how to proceed? Thanks, Matt

Hello, I have a shapefile of selected countries across the globe, but when I add it to arcmap, it places the countries really small in the middle of the atlantic ocean on my esri basemap; the projections are the same. How do I make the polygons (countries) in the shapefile bigger so that they line up with the basemap I am using? Any help would be much appreciated! Thanks, Matt
