Hi echomoon,

What kind of image do you have ?

In theory, to register raster map you require 3 dots forming triangle. These dots mustn't be very close to each other.

In MapInfo, the easiest way it to take 4 points - corner dots of the square raster image.

If you downloaded your picture from Google Maps/ Yahoo/Bing with a program, you will have these 4 coordinates.

If you don't have these coordinates, you should find them first before proceeding.

When you open the image in MapInfo, choose register than:

1. Add 4 points (Pt1 to Pt4)
2. Pt1 will be upper left corner - put the coordinates for this point and Image X = 0, Image Y = 0
3. Pt2 will be upper right corner - put the coordinates for this point and Image X = max horizontal image pixels, Image Y = 0
2. Pt3 will be lower left corner - put the coordinates for this point and Image X = 0, Image Y = max vertical image pixels
2. Pt4 will be lower right corner - put the coordinates for this point and Image X = max horizontal image pixels, Image Y = max vertical image pixels

Be careful tot to click in the map during the process.

Maps are divided in two classes - Vector maps (Roads, City Boundaries, etc) and Raster maps (JPG, BMP, etc)

I don't quite understand your point.

Raster image is every picture, including the photos you took with your camera.

As for vectors, in our case, is every MapInfo table that contains objects. All these objects (line, circle, irregular shape, etc) are vectors. Programs like AutoCAD work with vectors.

Another Telecom example - A MapInfo map with BSC areas (geographical boundaries) is a vector map.
