Proc GMAP Adjust Angle

bendsteel6 — Wed, 29 Nov 2017 21:03:21 GMT

I'm using the following simple code to create a simple test map of a (partial) North America:

proc gmap map=maps.namerica(where=(id in(260 926) and segment=1))
		  data=maps.namerica(obs=1)	all;
	id id;
	choro id / nolegend;
	run;
quit;

When the graph comes out it's angled a bit backward (See below). I think the NAMERICA table is already projected so I'm not using proc GPROJECT. Is there a way to make it straight?

Angled Map

Thanks!!!

You should define what you mean by "straight".

If you want the US portion to appear as it would when displaying maps.us then you will have to project it.

Newer files are available in the GSFK maps library instead of the older maps library. If you have access to it, I’d try that instead.

Hi,

By 'straight' I mean not rotated backwards by about 10 degrees. Also, I had tried projecting it and it came out backwards so I thought maybe it is already projected. Please realize that I'm relatively new at this.

I'll try using the MAPSGFK library as Reeza has suggested in her post.

Thanks

data my_map; set maps.namerica(where=(id in(260 926) and segment<=1));
run;

proc gproject data=my_map out=my_map latlong westlong radians;
id id;
run;

proc gmap map=my_map data=my_map all;
id id;
choro segment / levels=1 nolegend;
run;
