Using QGIS to input Esri ASCII data files, I uploaded many small files, each file representing a second of data: 16 sensors X 25 lines. Each file uploaded creates a small rectangle on my larger map layer. The default MAP Orientation of Esri ascii files is with the Top edge of the rectangle facing North and Right/Left sides pointing Directly North. I want to ROTATE this MAP rectangle, during INPUT, so the Right/Left edges would be at an Angle to North. Is there a command line option that allows this?

    Maybe it would be easier to understand the issue if you could add an image. – underdark Sep 28 '13 at 12:07
  • To visualize my problem, imagine Scrabble tiles laid out on a grid. If you lay them next to each other to spell a word, up/down or right/left there's no problem. But my tiles go off at an angle (with some overlap), making a diagonal. Instead of a smooth sequence of data blocks, I get what we used to call 'Jaggies' or a jagged edge. I want to rotate each tile as I lay it down so the data they repesent will lineup, just as it would if I orient the tiles Up/down or right/left. Does that make sense? If can only align my 'tiles' Up/down, the only Track that works is North/South. – BigIslandDigger Sep 28 '13 at 19:22

    Sorry, you lost me at "I want to rotate each tile as I lay it down so the data they repesent will lineup" – underdark Sep 28 '13 at 21:22
  • Each block of data my sensors record is a rectangle. On a map, oriented North on the top, each Ascii file of data becomes a small rectangle, rt/left sides are aligned with true North. However, the sled moved at say a heading of NW, making a strip of sensor readings. But when these blocks of data appear on the overall map, they march off at 45 degs and do not make a continuous strip of pixels. Each block steps up and over, staying N/S not rotated in the direction of the heading NW, much like a stairs. I want a ramp, not stairs. OK? – BigIslandDigger Sep 29 '13 at 1:07
  • What would be perfect for my purposes is a command line option that ROTATES the block of data away from the default N/S alignment, taking on any degree of rotation I input. – BigIslandDigger Sep 29 '13 at 1:09
