Mitch, Will and I (Dayne) represented GINA at the 4th annual GeoFest activity this last weekend. GeoFest an event put on as part the Geography Awareness Week; an event sponsored by the Alaska Geographic Alliance and the UA Geography Program. Mitch and Will joined me representing
This year we had two booth activities:
The first activity was the WhatWhere online map quiz. WhatWhere is a quiz that asks participates to try and identify what they are looking at or where the location is they looking at from GINA datasets throughout Alaska. This web map version created by Will expands on the idea from last years printed out version from last year by taking it online and using the GINA web services feeds for our datasets.
The second ad-hoc activity was inspired because Will brought his LeapMotion controller. The LeapMotion controller tracks hands and fingers allowing you to control applications with hand motions and gestures. The Google Earth integration is great and allowed kids and parents to fly around in Google Earth looking for interesting things such as the Great Pyramids or the UAF Campus. We ended up with a line of people and a few repeat visitors. We’ll be bringing a few of these to our booth at the Alaska Surveying and Mapping Conference in March so more people can try out this fun interface to Google Earth and GINA data. Seen below is Lakeye Scott who was visiting GeoFest from being stationed for his first winter in Fairbanks Alaska at the Eielson Airforce Base.

The GINA shorezone mirror: http://shorezone.gina.alaska.edu
The ShoreZone mirror URL points at our HAProxy load balancers (http://haproxy.1wt.eu) which forward requests to a single (at the moment) libvirt/VKM/QEMU virtual machine (http://libvirt.org/drvqemu.html) running the site as an apache virtual host (http://httpd.apache.org). The data is hosted on a 2-way replica glusterfs volume (http://www.gluster.org). Glusterfs provides a great way to store the data but currently suffers from some performance issues when there is a lot of filesystem metatdata (lots of files in a a directory). Fortunately, we can also mount that volume on the webserver with NFS (http://en.wikipedia.org/wiki/Network_File_System) which is much faster. Glusterfs is basically in its infancy and NFS is from the late 1980s. This blend of very new and very old technologies allows us to have reasonable speed while hopefully maximizing availability of the data.
The ShoreZone mirror is full of really cool data. I picked the awesome photo above at random. You can use the ShoreZone project here: http://alaskafisheries.noaa.gov/shorezone
The latest CIAP Surge newsletter focuses on Coastal Impact Assistance Program (CIAP) contributions to the Alaska mapping initiatives around the state. The CIAP funding combined with the SDMI state funding is making the GINA managed Statewide Orthomosaic Program go forward. The 2012 ortho tiles are finishing up acceptance this week and will be made available for download an through WMS and tile services in the coming months.
In the newsletter you can see a few other mapping projects that have pulled GINA into their orbit.
What this means is that, in addition to the (US) GPS satellites, the (Russian) GLONASS and (EU) Galileo navigation satellites will be added to the CORS data mix. This will allow better processing for those using GNSS-capable receivers.
As you might guess, Alaska GNSS CORS coverage is sparse, but it will improve over time and this is an important capability to keep in mind as you buy new “GPS” surveying receivers.
Big news is coming from the NGS CORS Team as they are getting ready to transition from publishing GPS only data to GNSS data. Taken from NGS CORS Website: The NGS CORS Team is ready to transition f…
Thanks to Joel Cusick of the NPS for the heads-up.
The 2012 SDMI Ortho-Imagery update is only weeks away. The above scenes of the Meade River dunes compare existing 15m Terra-Color imagery (bottom) with the soon available 2012 2.5m SPOT5 imagery. All of this can be easily accessed as a WMS. Details on this project can be found at http://alaskamapped.org/ortho .
GINA Puffin Feeder Android App available on Google Play Store!
GINA just published the results of our summer intern, @BobbySig on GitHub. Bobby made a dedicated Android Application interface to the GINA Puffin Feeder. You can download for your Android tablets and phones the GINA Puffing Feeder App from the Google Play Store
