Re: [Maptitude] Grid

[Chris Wagner]

A bit of confusion here.  you say a grid of 10 sq miles   but you mention spacing of 5 miles???? What I was able to do is open a map of WI   select the state and scale it to selection Map> Scale         show entire layer    State              selection set    Selection say OK Measure with the ruler icon the size of the window    I came up with 338  by 331 miles the square root of 10 is 3.1654205 take 338 * 3.1654205    =   106.7 take 331 * 3.1654205    = 104.5 No go to the tools > geographic utilities> create vector grid select cover map window with a set number of cells     I left the X Y degrees alone    and put the 106.7 for the X   and 104.5 for Y   said OK Now not all the grids are the same size exactly.....   they vary from 10.06 to 10.94 sqmi.   Depending on how accurate you really need to be .........   this may be a quick way to set it up. Now if you want a grid of 5 miles by 5 miles    (25 sqmi)    just change the numbers above and do the math. Chris Wagner debdemoe wrote: Hi! I need to cover my North Wisconsin map with a grid made with "blocks" of 10 sq miles each. I'm trying to use the Create Vector Grid, but so far no success. I know my latitude, longitude origin points, but I don't know where to specify that I want a grid spacing of 5 MILES. I appreciate any help. Thanks Yahoo!
