Apparently, this cool lizard is now supposed to be called Blainville's horned lizard? Sigh. I can't keep up with all the name changes, scientific or common. Eh, that's not the point of this post, anyways, even though I have seen a few impressively large horned lizards during my many recent activities.
Paul has suggested I try
iNaturalist as a way to document and share what I find during my weekly Pinnacles visits. I haven't decided yet, because I have questions about macro photo quality and GPS capability in a smart phone where there's no cell service.
Click here to see Paul's photo of this same horned lizard using his iPhone 5 (don't know which letter c or s), and then click on my photo above to enlarge. What do you think about the photo quality comparisons? I think Paul's appears very tan colored and a little flat, even though my depth of field is shallow. I'll mainly be taking photos of little butterflies about the size of the lizard's head anyways, but coloring is important. And, I'm still unsure how to resolve the pseudo-GPS in phones issue. I heard there are GPS units that bluetooth to the phone, but what a pain and more crap to carry. Does anyone have any suggestions to obtain accurate GPS linked to a phone-generated photo? Are there actual GPS phones, not the fake ones reliant on cell service?
Oh, have I mentioned I don't currently have a smart phone? I've had my flip phone since 2006, which I think is the responsible thing to be aware of in this day and age of disposable everything, including electronics.
I had my last computer for 10 years before I upgraded to iMac. I really don't need the latest and greatest toy, but it may be time to update. Plus, we've been needing to switch carriers for some time since many of
my calls get dropped at home on the Peninsula where ocean meets spotty cell coverage.
We never had a land line. There was a bit of a city hall brouhaha over additional cell towers being installed. On one side were the monarch butterfly lovers who didn't want the overwintering butterflies or themselves to be radiated (is that the term?), and on the other side was the city needing to offer basic public services, like cell phone coverage for emergencies. The towers went in, cleverly disguised as chimneys. Are we all being microwaved now?
ps 05/30/14 - One of the take-aways I got from the
Citizen Science Session of the Ocean Science Trust Conference last month was that
citizen science could and should be able to provide data rigorous enough for scientific review (Thanks, Lisa Emanuelson!). So, when a few days later
CalAcademy announced their acquisition of iNat, I paid attention.
Ken-ichi Ueda, co-founder of iNaturalist, has been kind enough to reply to my numerous criticisms (hopefully, constructive!) and questions as I figure out the best recording method(s) for my project, which in an unexpected way could also help shape its initial purpose. With Ken-ichi's permission, here's what he said, "
Ok,
let's talk tech. For iNat, my recommendation is to get the latest iPhone. Our
iOS app is quite a bit better than our Android app, and the iPhone's GPS and
camera are great. Here's are some particulars:
IMAGE QUALITY
As you pointed out in your post, the iPhone isn't quite as
good as a conventional camera, but it's still pretty good. It doesn't give you
much DoF control, but it can be quite sharp, particularly for stable subjects
that are close.
GPS
Any device with a real GPS chip should get coordinates
*anywhere* it has a clear view of the sky, since it works by communicating with
satellites, not ground-based towers. Reception may vary depending on weather,
topography, or the particular configuration of satellites in line-of-sight from
your position. Devices like the iPhone can improve both the speed of coordinate
acquisition and the accuracy of those coordinates by using cell tower and wifi
signals, but they aren't required. Almost every cell phone has a real GPS chip
on board, including every iPhone and most Android phones. Note that the
majority of tablets do NOT have onboard GPS. This includes the iPad.
In my experience the iPhone's GPS functionality is very
accurate. If you get a chance to look over someone's shoulder, you'll see that
the iNat works by continually acquiring coordinates until it gets the precision
below 5m."
To keep this from becoming free advertising for phones and
plans, I'm skipping some of what Ken-ichi recommends. Then, he goes on to say, "Regarding iNat
recording devices, keep in mind you don't need a phone to use iNat! You can
upload images directly. My usual practice is to use my phone for most observations,
but to also carry around my SLR and a handheld GPS in my pack. The GPS is
always recording a track, which I use to add geotags to my SLR photos later (I
use http://www.earlyinnovations.com/photolinker/ for this, but there are many
other such applications, including Lightroom). The SLR is much faster and
sharper, so for things like butterflies, that's usually what I'm going to use.
Getting identifiable lep shots with a phone takes more time and patience than
you can probably spend if you're doing a research project. Most high-end
point-and-shoots would probably be as good or even better (in terms of
flexibility) than my SLR setup."
Then, I asked questions about iNat itself.
I haven't found where it explains the different color map
markers (red, blue, green?).
"Colors relate to the "iconic taxon" of the
thing observed: blue for most animals, orange for insects / spiders / molluscs,
green for plants, purple for slime molds, brown for chromists, pink for fungi.
It isn't really explained anywhere. There are a lot of things on the site we
just assume people will figure out for themselves."
I also don't understand how the "Redo search in map
area" works, because it comes up with new and different points depending
on the zoom level on the map.
"It redoes the search using the bounding box of the
current map. It loads different observations because some of the observations
in your previous search will be outside the bounding box."
Then, how do you select the marker that sits just below
another one when on max zoom?
"
I guess you don't, but you can see them all in the
list on the right. You can also zoom in much farther with the satellite
tiles."
Is it
possible to select by week number to see everything found at a
particular location in that week of any year?
"
You can't look up observation by week, but you can do it by month. If you go to http://www.inaturalist.org/observations
and click the "Search" button you'll see a bunch of filters, one of
which is a month filter. If you set that and leave year and day blank,
you'll see all the observations added in that month, regardless of year."
... He did say he privatizes his locations, does not carry a GPS
unit, guesses based on a google app, so maybe that was the result of
being "
obscured" as well. It doesn't seem like that should qualify
for "
research grade".
"
... his observations for that day is due to the fact that he obscures the
coordinates, which means each observation is displayed at a randomly
chosen location somewhere within 10km of the true coordinates. iNat's
"research" quality grade doesn't consider how precise the coordinates
are, just that you've added them. The name "research" was probably a
poor choice since it seems to get people's ire up, but it just means
observations of that grade are probably more accurate / complete than
others. Then again, the definition of "research" is pretty flexible. For
some studies, precision of 50k might be adequate."
Finally, in the spirit of encouragement to become better, I had the audacity to question Ken-ichi's algorithms. It's a bit meta, and I've noticed not everyone appreciates the different perspective. In fact, he seemed very receptive to it. I agreed with him that the freedom to make errors is educational, which is why this hobby blog has been so liberating for me over the past 5 years. By being okay to make mistakes, being honest in the not knowing, asking those questions, and accepting of others' help, I have learned so much. Here's Ken-ichi's reply to my algorithms charge:
"I would argue that our crowdsourcing approach generates data that is
close to the accuracy of professionally collected data, with the added
benefit that it usually comes with media evidence for independent
verification. It is generally not as comprehensive as professionally
collected data (most casual naturalists aren't going to identify every
carabid under a log in the way that a working coleopterist would), but
if you look at the inaccuracies present in supposedly professional
collections at museums or in GBIF, you will find most of the same
geographic biases (no collections far from roads or trails),
identification mistakes, and taxonomic confusion... except it's really
hard to see this errors because either there's no associated media
evidence or you have look at a specimen. An actually quantitative
comparison between professional and crowdsourced data collections like
this would be a pretty cool outcome of being at CAS. We shall see."
This is all very helpful information for me. Thanks, Ken-ichi!
The future of natural history documentation is
at our feet, a path extending into the digital age through the eyes and
hands of millions of curious participants. I know that sounds corny,
but it's true. This is exciting stuff! It's too bad it currently
selects for the well-to-do with expensive phone requirements, GPS
devices, and fancy cameras. The reality of the situation is nature is available to
pretty much everyone... and it's free, if we just put down our electronic devices.
