Also, it is with GIS-type software that I have seen air-photo images created that are difficult to use: the UTM grid is visible, but it's at a scale that requires making up some kind of paper scale to measure anything.<BR/><BR/>The software can be used to create images at certain "real" or standard scales, but sometimes that's hard to do, especially when using the software for the first time. That's my limited experience with GIS programs - I don't even know what program it was.<BR/><BR/>Another thing - all/most mines usually have their own mine grids for location, which goes back to pre-GPS days - so sometimes there are two locating grids in use: UTM and the mine grid. I'm hoping mines will all go to just UTM sometime (soon!). Of course, this is all from the U.S. I don't know about other countries.Silver Foxhttps://www.blogger.com/profile/03131032620978696727noreply@blogger.comtag:blogger.com,1999:blog-8693614218792476252.post-4026227329911885412008-10-05T21:32:00.000-07:002008-10-05T21:32:00.000-07:00very useful discussion. i am just thinking how fle...very useful discussion. i am just thinking how flexible the concept of scale has become with people now using images as a backdrop in a GIS software and zooming in and out and drawing geological overlays on it!<BR/><BR/>any thoughts on that?<BR/><BR/>cheersSuvrat Kherhttps://www.blogger.com/profile/18281172632784780810noreply@blogger.comtag:blogger.com,1999:blog-8693614218792476252.post-13563796118215182432008-10-04T19:42:00.000-07:002008-10-04T19:42:00.000-07:00Thanks, Brian - I had noticed small v. large scale...Thanks, Brian - I had noticed small v. large scale used incorrectly somewhere, and was thinking about it.<BR/><BR/>Hypocentre, that's why maps should really have bar scales. But even then, if there is an absolute scale written somewhere, then it has to be changed - and that can be hard to remember!<BR/><BR/>I've had maps changed to almost unusable scales by reduction or enlargement - to scales that there aren't any <A HREF="http://www.forestry-suppliers.com/product_pages/View_Catalog_Page.asp?mi=5928" REL="nofollow">rulers/scales</A> for.Silver Foxhttps://www.blogger.com/profile/03131032620978696727noreply@blogger.comtag:blogger.com,1999:blog-8693614218792476252.post-59397658885453859272008-10-04T13:30:00.000-07:002008-10-04T13:30:00.000-07:00A common mistake my students make is to include a ...A common mistake my students make is to include a map (or part of one) in a report, expanding or contracting to fit the page, but forgetting to revise the scale in the figure caption.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8693614218792476252.post-24684620095560461322008-10-04T10:10:00.000-07:002008-10-04T10:10:00.000-07:00nice post ...
