Spatial Adjustment Toolbar: Lining up Space Syntax maps in ArcMap

[JoeySchaasberg]

From DepthMap, a Space Syntax software programme, I have exported a MIF file, converted it to a shapefile. It does not have any project or coordinate system. I try to line it up with other maps I have (which do have a coordinate system), but i can't get it to work. The space syntax map load into the file, but very far away from the rest of the map. I have mostly been trying with the Spatial Adjustment toolbar to put it at the right place. But when i select the data create adjustment links and click Adjust, the lines do not move at all. When i try to move some testlines of another file, this is no problem.

Maybe it has to do with the fact that when I load the space syntax map into ArcMap, i get the "Inconsistent extent" error. Also in the "Set Adjust Data" window, the space syntax layer does not show at all. Why is that?

Do you have any ideas, tips or help how I can line the two maps together? Your help would be really much appreciated!

Hi,

"Inconsistent extent" should occur only if the data already has a defined coordinate system. It's triggered because the data's extent doesn't match what the coordinate system supports. One example is if the coordinate system is a geographic one using decimal degrees, but the data extent has values that too large for decimal degrees. Or it can occur if the data has a projected coordinate system, but the extent is too large for the valid mathematical area of the coordinate system.


Whatever's there may be confusing spatial adjustment. Try 'clearing' the coordinate system in ArcCatalog before adjusting it.

You're positive that it isn't in a known system? Can you post the data extent and what location it represents?
