Converting Non-Spatial Data to Spatial Data

    I have been looking in my SSRS book and online and can not find a clear answer to this question. I have a list of 30 dummy CPT codes in our EHR that our MD's use while on Outreaches to different shelters or Motels each dummy code represents the location they are doing their Dr. Visit at. For instance code (OR001)CPT Code = Label (Albuquerque Rescue Mission). I would like to be able to convert each code to a spatial Long and Lat that i can then use in Report Builders mapping tool. I do not mind looking up each of the 30 codes actual Long/Lat using bing.

    If I could get the spacial conversion, we could create a Heat Map over our city where we have the most outreach encounters.

    What is the best process or where can I find good information on accomplishing such a feat.

    Any help is appreciated

    Thanks Thomas

    I suppose if you don't mind manually doing this, you could locate each of your CPTs in Google maps. For each one right click in the map and select 'What's here'. That should put the Lat/Long in the search field.

    Another way is to click the link icon which will pop up a dialog with an URL like the following:

    https://maps.google.com/?ll=35.284589,-95.583394&spn=0.000835,0.001414&t=h&z=20

    The lat/long should be the center of the map

    But how would i do that in SQl? I figured I would need to have some sort of statment saying that when code OR001 is returned it equals a specific Latitude and Longitude... Of course hand entered via looking up each location as the way you described. This is a hard one because evry thing I find on spatial data assumes it is already part of the result set. I want to add the spatial data to my result set by hand since its only going to be 30 seperate values.

    If I said that I wanted each zipcode from our registration to equal a specific lat/longitude that I picked by hand would that make more sence as a way to describe my issue?

    I think you just need to create table with columns code and location.

    create table codeToLocation (code varchar(20), location geography);

    After setting up data you just join this table to your query.

    Yes, I think this is what I am concluding could I still do this with just a temp table? Sorry if the question sounds dumb still very new.

    Sorry for the delay getting back.

    There would be no problem using a Geography in a temporary table

    CREATE TABLE #TempLocation

    (Code Varchar(5) PRIMARY KEY

    ,Location Geography

    )

    INSERT INTO #TempLocation

    VALUES ('OR001',Geography::Point(-95.583394,35.284589, 4326))

    ,('OR002',Geography::Point(-95.583494,35.284579, 4326))

    SELECT * from #TempLocation

    Please note the coordinates I have used are probably no where near where you want them:-)
