I'll help but you can't just ask the internet to do your papers and assignments FOR you! The next time you're at the doctor, just think of how much he might of had to cheat to get thru his medical exams as he brings the knife down on you.





Vector means lines and points. There's no way to take a picture with a camera and have it instantly converted to vector. You'd have to sit down and trace the outline of each detail with a tablet connected to your computer (see A Scanner Darkly or Waking Life for examples).





You can make Bitmaps of anything but bitmaps are grids. No matter how high your bitmap's resolution is you're stuck with jaggy lego type estimation of a line, not a pure line from point a to b unless it's EXACTLY 90 degrees.





I hope this helps, and I really hope your professor doesn't suck in your next class, because if s/he was any good, you wouldn't be asking this question. Seriously!
Reply:Vectors are for lines and curves, bitmaps (raster) are for photo style pictures, so:





a) vector


b) bitmap


c) vector


d) bitmap





Also, vector images (e.g. in SVG) are a lot smaller in filesize than the corresponding bitmap image.





Hope that helps.

Reply:Well, for a start, I'll quickly explain the difference incase you don't know. It should be pretty simple to figure out then. A bitmap image is composed of pixels, with colour values for each of the pixels. This mean they can store detailed pictures but they don't resize without loss of clarity. A vector graphic stores the details of an image as a series of geometric values, such as lines, curves and some more complex shapes. This makes it great for diagrams and it resizes well, but it can't capture fine detail.





Now then, onto the question





a) Vector - the diagram is going to be composed of simple shapes and text


b) Bitmap, photographs can't be represented as vector images because of all the fine detail


c) Vector, this can be comprised of simple shapes and lines


d) Bitmap, since you're going to want all the fine details captured in the aerial photograph. You could always overlay the vector map over the bitmap image to make the roads clearer - this is what you see when you have roads enabled on Google Earth.
