[CTPP] SAS Question

Below is a response to Mara's question that got bounced from the mail list since it was from a non subscriber. ------------------- Subject: RE: [CTPP] geocoding in SAS From: "Seitz, Leonard E@DOT" <leonard.seitz(a)dot.ca.gov> Date: 8/9/2016 11:43 AM To: "Portillo, Diana M@DOT" <diana.portillo(a)dot.ca.gov>ov>, "ctpp-news-bounces(a)chrispy.net" <ctpp-news-bounces(a)chrispy.net> This SAS/Graph Procedure should work: Overview: GINSIDE Procedure The GINSIDE procedure compares a data set of X and Y coordinates to a map data set containing map polygons. The procedure determines whether the X and Y coordinates for each point fall inside or outside of the map polygons. If the point falls inside a polygon, then the ID variable is set to the ID value of that polygon. For example, if a map contains states, then the ID variable of the output data set is set to the state that contains the point. The GINSIDE procedure can be used with the SAS/GRAPH map data sets and the results can be used to annotate onto a map with the GMAP procedure. Note: Avoid unpredictable map results with points that fall on the border of a polygon by using the INCLUDEBORDER option. This option includes points that are on the border of a polygon in the output data set. These points are identified by the variable named _ONBORDER_ with a value of 1. Copyright © SAS Institute Inc.
