US National Map Corps

Last week I attended a web-based presentation by USGS on the National Map Corps. I don’t know if you are familiar with USGS’s National Map or not, but it is a great resource for finding and downloading information. I had not heard of the USGS National Map Corps before, so this was good news to me.

USGS has adopted the same editing environment for the National Map Corps that OpenStreetMap has used for a few years (Potlatch). It works well, is simple to use, and they use it to update a few features for the US Topo Map. The features you can currently edit across the US are: schools, fire, police, and EMS locations, state capitals, and cemeteries. Not a lot of features to update, but it is nice to see USGS opening up to crowd sourcing to keep features current and accurate. The updates you make on the map are reviewed by peers and then added to the new US Topo Map quads.

Creating a File Geodatabase in ArcMap 10.1

We wanted to add some video tutorials to show new ArcGIS users how to edit data in ArcMap. Step 1 is to create a File Geodatabase. In this video we cover creating a File Geodatabase in ArcMap 10.1 that we will use in our next video to add data to our project. To see all of our ArcGIS tutorials please visit our YouTube Channel.

Georeferencing Imagery in ArcGIS 10.1 Desktop Tutorial

We have had a lot of people lately ask us how to georeference imagery. So, as long as it is a hot topic, we just posted VerticalGeo’s new video tutorial on “Georeferencing Imagery in ArcGIS 10.1 Desktop” on our YouTube Channel. Here it is:

Making Sense of Maps

Here’s a great TED talk by Aris Venetikidis on the difference between the cognitive maps we make in our mind and the physical maps we use in the world. Very similar to my dissertation concept of a cognitive landscape that an author uses as a setting for a novel.

How LiDAR is Revolutionizing Maps and Geospatial Data

Thanks to Art Borum of Kaskaskia College for pointing me to a great article by Patrick Marshall (no relation) titled How LiDAR is Revolutionizing Maps and Geospatial data. LiDAR (Light Detection and Ranging), which uses laser beam pulses to measurement of elevation, truly is a transforming technology.
