The app lets users measure distance between points, between
a point and your current location (if your device’s GPS is enabled) or along a
path of points. GeoViewer can see geocoordinates
of any location by touching that place on the screen. Users can look at layer properties, the
coordinate reference system being used, the layer’s geo bounding box,
dimensions, colors pace, data type and resolution. Users can also search locations by geographic
coordinates in WGS84 (Lat/Long) or in the images native coordinate system.
Lizard tech has previously released a version of GeoViewer
for iOS. These two apps are essentially
the same with one exception. The iOS
version can except that it can not pull layers from WMS servers. LizardTech states that this functionality
will eventually be added to the Android version.
GeoViewer for Android requires the device to be running
Android version 2.3.3 or later. The app
is free on the Google Play Store.
I downloaded the app to my phone and my Nexus 7. It worked very smoothly. I added several MrSID files to the device and
it worked just like viewer should. The
images were clear and taking measurements was simple enough. This viewer is great for viewing high quality
MrSID files off line. My first thought
was why would I ever use this when I have access to Google Maps? What if I’m offline? Google Maps has the ability to go “off line”
but it takes a lot forethought and pre planning. But GeoViewer gives me access to my MrSID
files. That means I can get the latest
aerials on my device. Google’s images aren’t
always the latest. Opening those files
was easy enough. I emailed a smaller
MrSID file to myself and I loaded others to my Dropbox account. When access the MrSID files either way the
option to open them in GeoViewer popped right up.
LizardTech’s GeoViewer for Android is a good, simple, easy
to use MrSID (and JPEG 2000) viewer at the right price! Go check it out.
