David B. Zwiefelhofer

I’m a late baby boomer. A programmer. Mostly web-based these days. PHP, MySQL, JavaScript, etc.

I’m publishing a blog because there are a few things that need to be said. No. I’m not going to say them. I’m just serving as a cautionary tale for those who don’t speak up.

Really, I prefer to remain anonymous in most everything I do. I’ve been involved in web publishing since 1996 and I’m publishing my first personal blog in 2012. This is an indication of how much I want you to know about me.

With that in mind, I intend to focus my writing here on things.

  1. Hi David,

    I am doing a test run on your batch geocoding website, Batch Geocoding
    http://www.findlatitudeandlongitude.com/batch-geocode/#.VSsRI_mUcdo, and found the results accurate.

    The only issue is I am seeing that it is processing at 1000 addresses an hour, which is a bit slow and I think the website was created some time ago and I am wondering if you have a current version that can geocode faster.

    Regards,

    • Hi David I´m triying to use yourse “Batch Geocoding”, but I want to know how does the number of the accuracy of an adress are generated.
      For example :

      México, Estado de México, Luvianos, Paraje de Santa Cruz gives me an accuracy of 3
      México, Oaxaca, Matías Romero, Las Cruces gives me an accuracy of 5

      I want to make buffers around my points, so I am searching if I can give a certain buffer size based on the accuracy numbers generated

      Thanks and I hope you can help me with that

      • Accuracy…
        9 – rooftop
        8 – address range
        5 – city/municipality
        3 – region
        0 – fail

        Status…
        200 – okay
        602 – unknown address
        610 – invalid address
        620 – over query limit

  2. Your bumper sticker “33 degrees (with the proper degree symbol) 1′ N 117 degrees 16′ W led me to spend several hours on maps trying to find the exact location. Google maps does not have a search based on coordinates – at least not that I could find. First I found a “cities” location for Escondido but that was too vague. With further research, I found this address in Cardiff (1118 Wales Pl, Cardiff, CA 92007, USA) as well as links to your various social media pages. It appears that you have created a web page to search for exact coordinates, however that page was very difficult to find in a “Google Search” So… what is the significance of the bumper sticker? Is it just to get the overly curious/obsessive compulsive to spend hours searching for its meaning?

    • My bumper sticker? I don’t know why you’d think I was connected to a bumper sticker with those particular coordinates.

      My only connection is I own a website that allows users to locate various coordinates on Google Maps. This isn’t much of a connection. 😉

      • Thank you for your response – I saw a bumper sticker with those coordinates and nothing else while driving on Del Dios Highway. I was curious what the intention of the bumper sticker was – if it was advertising a business, a special place (maybe a meta physical meaning – a vortex or something) so I searched the coordinates and found the above residential address along with your links. That’s all. So in the end, I guess it was advertising – unintentionally – advertising your services! (at least by my search).

    • Open Google Maps.
      In the search box at the top, type your coordinates. Here are examples of formats that work:
      Degrees, minutes, and seconds (DMS): 41°24’12.2″N 2°10’26.5″E
      Degrees and decimal minutes (DMM): 41 24.2028, 2 10.4418
      Decimal degrees (DD): 41.40338, 2.17403
      A pin will show up at your coordinates.

  3. I stopped by to see who wrote this marvelous free geo code conversion site. I have been reading through your travel blog and and now even more impressed than before. You look like you are having a good time. Thanks for the solid bit of work. I appreciate it.

  4. I’ve been using your batch geocoder and have found it very useful. My question is what geographic coordinate system are the latitude and longitude results based on? Thanks very much in advance.

  5. Hello David.

    Just noticed that the message: “The batch geocoder is offline until further notice. We hope to bring it back as soon as possible.”

    Is this just maintenance or something more? Your tool has helped me out greatly with a project I’m currently working on.

    Thanks

    • Hi Richard,

      I’m sorry for the inconvenience. We’re working on bringing it back as soon as possible, but it is going to be a while longer.

      Thanks,

      David

  6. Hi. My friend owned a sweat-shirt with coordinates that led to you, and while surfing the net a bit longer, found a great city vacation destination. Thanks.

  7. hello, your coordinates web site is very helpful…now it appears highly shadowed and has “for development purposes only” showing…why is that?? still usable, but harder to read for my old eyes….nicely dome though!!!
