Build a Map of Ireland with Counties in SAS VA

Bill_D — Wed, 10 Dec 2014 14:14:53 GMT

I am trying to build a simple map/graph of the Republic of Ireland, with 26 counties, in SAS VA.

I have been able to build the outline of the a map/graph, with the outline of Ireland using just the ISO two letter code - IE. (I have specified as a geographic variable.

However, I am unsure as to which value to use for the county.

I have created values as below (county/clean county are just value I have use to clean up the county in our own data).

COUNTY	CLEAN_COUNTY	PROVINCE	_MAP_GEOMETRY_	COUNTRY	ID	REGION	IDNAME	OLDID	ISO_CODE
CO CARLOW	CARLOW	REST OF LEINSTER	id 1 of maps.ireland	470	1	I	CARLOW	1	IE-CW

The highlighted varaiables are all taken for the Maps library in SAS (Ireland & Ireland2 datasets).

Can I just us a SAS Map ID variable or are the X/Y co-ordinates for each address required or the county mid-point?

I hope this this makes sense.

thanks for your help

Bill

Hi Bill,

Please check this previous discussion, maybe it helps you out in a different way. https://communities.sas.com/thread/57062?start=0&tstart=0

You can ask google for the center latitude/longitude by county and use the custom geografics.

Greetings Peter

Hi Peter,

Thanks for the reply. This is and will be useful.

I had managed to get the center latitude/longitude by county and create a custom geography (the large bubble is Dublin) but as you can see below I do not have any county boundaries. The map on the right uses the SAS Region name 'Ireland'

Do you know if SAS VA should display each centroid within its county/SAS defined sub-region boundaries?

I tried to create a hierachy linking country -> county centroid but am not able to get the points to map onto the larger Ireland map.

Thanks

Bill

Hi Bill,

sorry but no experience with county boundaries, I always use cent coordinates given by Google.

So I store the Log/Lat of the customer and center of country. Then the average of the countries by GeoArea is my lat/log for the GeoArea.

While assigning these Log/Lat coordinates to Customers/Counties/Countries/Area's, I create the drill-down hierarchies.

Anyway I am using 6.3 and will upgrade jan 2015 to 7. Lets see if there are new options..

greetings and good luck.

Hi Peter.

That is perfect. I will use this method to build the hierachies that I need.

Thanks for your help.
