Geocaching podcasts

Geocaching is, of course, the activity where you go out and find caches based on a lat/long and a few hints (apparently there are now audio hint caches, as well). With such a large hobbie there has to be a podcast to join it, here are the ones that I have found:

  • PodCacher
  • GeoRadio
  • CacheCast
  • I haven’t listened to any of them yet, but they have been added to my aggregator!

    Magic in the Muggle World: The Marauder’s Map

    By: Jesse, November 14, 2005

    With only a few days left before the release of the 4th movie in the Harry Potter series, The Goblet of Fire, I thought it might be time to follow in Mapz‘s lead and look at how an item from the magical world compares to our muggle technology. The Marauder’s Map is a piece of parchment enchanted by four rapscallions in their younger days at Hogwarts School of Witchcraft and Wizardry, which finds its way into the hands of Harry (thanks to the boundless generosity of the Weasley twins). This magical map is a detailed representation of the school: the different rooms, hallways, floors, and many of the objects within the school…all of these things AND a “real-timeâ€? tracking of the location and movements of each person (even pets!) within the school.

    This is similar in concept, if not operationalization, to the current vision of the use of RFID tags on students and employees to track their movements. In the “muggle� (non-magic users) world, we have a GIS, desktop or mobile, a way to map the features of our own castle and grounds. We also have a GPS to track ourselves and others wirelessly as we wander the grounds of our castle. But what about inside, indoors within our castle, how do we know and therefore show where we are? No matter the size of our castle (or shack) we can’t reliably use standard GPS-enabled devices. This is tied to issues of signal strength and in our courtyard there is the issue of the urban canyon, or signal bounce. But there are options, as we walk into our castle. Our RFID tag embedded in our wand, I mean wallet, is read as we walk through a doorway. If each doorway has a reader we can know what room we are in. Brilliant, … but not yet a true Marauder’s Map. We do not yet have the accurate real-time tracking.

    So, let’s toss our RFID aside for the moment and use our wireless connection. MIT’s iSpot gets us close to a user’s location, gives us a building, a floor, probably a room. If we switch over to Ekahau’s approach, then we can get fairly close to our real-time location through wireless, but the problem is that someone has to wander through prerecording relative signal strengths in order to use later. Good, but time consuming, and it may not be reliable if you add different hardware to the system. I think the closest we can get right now, outside of the DOD, is probably Qualcomm’s GPSone. This assisted GPS solution integrates GPS information with wireless network signals to yield a pervasive location solution. Now, I speak from the documentation on GPSone not the use of it, and we all have a cell phone after all. Your first grade child or niece or nephew has one right?

    Marauders MapSo, let’s see, we have our magical tool, the Marauder’s Map, and our muggle options to make it happen. We don’t have to do it just one way; we have choices to make based on what we really want (I, for one, do not wish to know which stall you are in). And with our results I think it is safe to say that we could convince all but the most jaded that any of our muggle ways of creating a Marauder’s Map Lite � really is magic. Of course, now that we have it, the question is: who will get to use it and what will they use it for? Important questions to be sure, but maybe we will leave the issue of “Big Brother� and civil liberties to another day.

    GAW Day 1: Physical Geography

    As I have mentioned before, I see Geography as a series of relationships and as we look back through the history of Geography we see three main areas that we can use as umbrellas for the broad aspects of Geography: cartography, human geography and physical geography. Physical Geography covers the relationships within the environment around us, a broad area to be sure, but an important one in our daily lives.
    Continue reading “GAW Day 1: Physical Geography”

    Welcome to Geography Awareness Week at VerySpatial

    This week we will be taking a look at five broad areas within Geography, beginning today with Physical Geography with the rest of the week as:

    Tuesday – Human Geography
    Wednesday – GIS Day complete with podcast
    Thursday – Cartography
    Friday – A round-up of the myriad of topics that we won’t be covering

    We will have the first up later today.

    All entries must be received by December 1, 2005 to be eligible. We will be giving away SWAG from the VerySpatial store. Winners will be announced on Episode 20 of the podcast on December 4, 2005.

    Online Soil Survey: CA, AZ, NV

    A couple of months ago I mentioned the role out of the NRCS’s Web Soil Survey. Today we bring you a localized soil survey page for CA, AZ, an NV out of UC Davis’s California Soil Resource Lab. While portions of the interface are very similar to the NRCS’s product, their site does offer some additional tools missing in the WSS.

    If I understand correctly, they also used MapServer for the backend as opposed to ArcIMS for the map product, which while it doesn’t offer some of the features of ArcIMS/Server out of the box, it is stable and openSource so there is always room to grow.

    Thanks to Dylan for pointing this out.

    avsp GIS Day Podcast

    SE03 will not be from the ASA-CSSA-SSSA conference since I didn’t get any usable audio (what I have is good content, just not good quality).

    Instead we will be hosting our first avsp GIS Day podcast for release on the 15th or early on the 16th. We hope to cover a bit of an overview of what GIS is and have a couple of short interviews with geospatial technology professionals. We plan to keep it to our regular 30-35 min format to make it a viable tool for the classroom.
