Geodist and insufficient memory

craigwe85 — Fri, 26 Oct 2018 14:02:41 GMT

Hello, i currently have a table set up as which is called "store_long_lat"

I would like to calculate the distance between Latitude Longitude, and Latitude1 Longitude1. and call it distance within the same table. There are 2000 rows in this table so I wold like to stray from the method where you have to input your Long and Lat values . I tried the below code and it produces a table with no data. Feel like am I close but just cant get an output to produce.

data distance; set store_long_lat;
input Latitude Longitude latitude1 longitude1;
distance = geodist(Latitude, Longitude, latitude1, longitude1);
put 'distance = ' Distance 'Miles'; datalines;
run;

I ran the below which produces a distance value inthe log but this does not work for my scenario:

data _null_;
distance = geodist(44.746052,-65.516649,43.68,-79.63);
put 'Distance= ' distance 'kilometers'; run;

Hello @craigwe85,

Just delete the INPUT and DATALINES statements. These are not required and in fact wrong because you read all data from a SAS dataset by means of a SET statement. Further, for a distance in miles you need to specify 'M' (case insensitive) as the fifth argument of the GEODIST function. Not sure how "insufficient memory" could be a problem here.

Edit: The PUT statement would write 2000 lines to the SAS log. Do you really want that?

data distance; 

set store_long_lat;

distance = geodist(Latitude, Longitude, latitude1, longitude1);

run;

proc print data=distance (obs=5);
run;

If you use SET it's unlikely you'll have an INPUT/INFIILE statement.

Perfect thanks.. works great. Fairly new to SAS and was just taking bits and pieces to other things I have found.. insufficient Memory was not the error.. Must have clicked on wrong subject when it popped up.

Anyhow.. thanks a lot for your help
