Need a way to calibrat a map in PDF format

[brukat]

I have access to public maps for New-Brunswick province but all maps are in PDF format so I'm not able to calibrate them with Fugawi program. The program only takes BMP format. Wend I save PDF in BMP I loose all my resolution???

Fugawi also supports GIFs but I don't know if that will help with resolution.

I use PDF-originated maps from time to time in GeoBuddy. I zoom them to 300% in Adobe Acrobat Reader, and use the Select Image tool to drag a selection box over the entire map. Copy and paste into your favorite image editor, and save in JPEG format. I then calibrate it by identifying three obvious points (like street intersections) using the aerial photo view in GeoBuddy.

 

It can be done. Once you get the hang of it, the hard part is just waiting for Acrobat to scroll down to the bottom of the image so you can export it at 300%.
