The VuePod can view many different types of data, but for this post we are going to focus on lidar data. According
to Wikipedia lidar data is defined as a remote sensing technology that measures distance by illuminating a target with a laser and analyzing the reflected light (http://en.wikipedia.org/wiki/Lidar). The reflected light is then used to make high
resolution maps and 3D images based on the amount of time it took for the light
to return to its’ source.
Lidar data can be very expensive, which is why the internet
can be helpful. There are many websites
where lidar data is made publicly available, such as government websites. However, the resolution of publicly available
data may not be as good as you want. But
a website that we recommend when searching for lidar data is Open
Topography. This is an open source site
where you can download lidar data at a fairly high resolution.
Figure 1
The website is very simple to use. First, select the region in which you would
like data from. Figure 2 shows the
selection of Provo, Utah.

Next, choose the data source as shown in Figure 3.

Lastly, click on the download as in Figure 4.

As mentioned earlier, this data can also be found at government websites such as gis.utah.gov.
