You are right about storing updated data on the hard drive. In fact that is just how Map Expert stores user corrections. From the info in your message you must know a lot about GIS and such. Do you do anything with GPS? ken/Deep River Publishing

I first worked with a GIS in 1979 when I implemented a system that assisted in balancing territory loads for field engineers. As I recall it printed out the expected monthly workload for an SMSA(Standard Metropolitan Staistical Area) for a given product. These were copied to acetate and then overlaid on physical maps to assist the Field Service Manager in defining territories that had approximately 176 hours of workload per month for an average FE. Not very elegant but it did help especially in showing an employee who thought he was overworked that his territory was, indeed, equivalent to other employees. I also worked with a friend who had a business selling advertising on maps that were given away at hotels, tourist attractions, etc. This was all cut and paste work but it made me realize how inaccurate most maps were. I'm currently in the thinking stage of a software application that would allow a walkup user to locate and print out a map for his desired destinations. Such systems are currently in place in some hotels & car rental agencies, I believe, but must be pretty expensive since they aren't more prevalent. Of course, such a system could be used in amusement parks, shopping malls, outdoor recreation areas, department stores, K-Marts, etc. It could even be done over a telephone with resulting maps sent to a Fax machine. My only experience with GPS is the one that was on a used boat I bought last year. Since my boating is limited to the Lake Erie islands, a very small area, I don't use it much. It does output the location coordinates to an LCD screen which is displaying the local charts. I imagine it would be pretty simple to read in the coordinates and overlay a symbol or identifier on a product such as Map Expert since each GPS tranmitter must have a unique ID. Jim

Very interesting work. Have you ever run across a digital source for zip code polygons? I have some friends who could use them. ken/Deep River Publishing

Now that I think about it the manpower planning tool I implemented in 1979 used zip code polygons for some reason. I vaguely recall the maps. Perhaps something to do with determining the location of equipment. I'm certain today we would use 9 digit zip codes to locate equipment by SMSAs. That data came from R. H. Donnelly Company I believe but I would also check with the U.S. Postal Service. The USPS certainly wants to encourage zip code use and may have such info available at reasonable cost. Jim

I've had no luck with the post office. They hand draw zip code maps for delivery use. Also, it is hard to know who to talk to. When I was looking I got a lot of people without a clue as to what I wanted. Donnely must have good data but the price must be high. thanks. ken/deep river
