Showing data on unknown grid, with scale bar

#1



Hi,



I want to show data that doesn’t really belong on any known grid.   I wanted to setup my map such that I can see the markers, and also a scale bar.   In the future, I’d like to add a shapefile, grid, etc.   



The code below shows 3 points from my datafile, that I wanted shown on the map.  The points do show, however, the ScaleLineAdornmentLayer does not.  I’ve also put these points into the MapSuite GIS editor, and I can get it to show the scale bar properly.



I’m wondering if there is a default projection (or some other setting) I can use to make my map show in the same was as the MS GIS editor?



(Note, because these are client supplied files, I don’t really have any idea of
the range of points to be displayed (eg in one file the X coordinate could
range from 0-300, in another it might be 50,000-60,000, but in all cases, assume the data is 1::1m 



Thanks,

Steve

Hi Steve, 



Thanks for your post, and would you please try the attached code, now the scaleline should be visible.

Another thing for your information is that, in your code the three shapes actually are in meters, so, the wpfMap.MapUnit  should be  GeographyUnit.Meter rather GeographyUnit.DecimalDegree.



Hope it helps

Thanks, its working now.

Not sure why I had it set to DecimalDegrees :(

Hi Steve,


Here is also a sample to display points in blastholecollars5204002. The sample could also show you how to display the isolines created with blastholecollars5204002.csv.


Hope it helps
