I would like to know how to begin to digitize a .jpg file. I have the 2D Drafting Workspace selected. Next, in the Map Drafting tab, do I insert an image with the Insert Image tool? I did this and a new window called Image Correlation came up asking for insertion points. Is this how I register or georectify the .jpg file.
Or something completely different needed? For example, do I need to convert the ..jpg file to a different type of file? I am digitizing a section map of drill holes/.
What I am looking for is the step-by-step process. Thanks.
world file... could be .prj or .tfw extension
Worldfile belonging to a JPEG may only have .JGW extension, sir.
After vectorising that raster by means of Wintopo, you could _ALIGN the vector result according to a couple of GPS points, or an ortophoto loaded from a WMS server.
It means automatically transforming raster graphics in vector lines, instead of manually digitizing point by point.
About georeferencing a bitmap, it's not a good idea in my opinion: you'd better use Wintopo, then _ALIGN the vectors on the Earth as advised above.
Before saving the aligned drawing, don't forget to issue the correct CRS with _ADESETCRDSYS command.
