Chris,<div><br></div><div>I think I discovered my last issue. The ArcGIS api seems to be putting the rows in reverse order. Either top-down or bottom up, depending on the reverse of TMS. For my initial zoom level, I subtracted the row number from the total number of rows (3 rows), and my map looks good. Is there a way to find the number of rows for a given scale level?</div><div><br></div><div>Thanks,</div><div>Scott<br><br><div>
