Fun with GIS Using AGX#21: Integrating Tools

People often ask "If I want to do data analysis, what tool should I use?" Several weeks ago, I wrote a different blog entry about tool use . As I tell people, I use ArcGIS Desktop (either ArcView or full ArcInfo ), and ArcGIS Explorer (or "AGX," ESRI's Read More...

Teaching About Watersheds With Online and 3-D GIS, Part 2

Another excellent resource to teach about watersheds from a spatial perspective is the EPA’s Surf Your Watershed site ( http://cfpub.epa.gov/surf/locate/index.cfm ). For each watershed, environmental threats, streamflow, citizen-based action groups, and Read More...

Teaching About Watersheds With Online and 3-D GIS, Part 1

Why teach about watersheds? As the area of land that drains all of the water falling into it into a common waterway, watersheds are connected to a larger system. Furthermore, each is a part of a larger watershed. Thus, watersheds (or drainage basins or Read More...

Studying Paragliding Using ArcGIS Explorer: Another Way to Calculate the Total Distance Traveled

We have been studying paragliding. We mapped the paraglider’s GPS track in ArcGIS Explorer, calculated the vertical and total distance traveled, measured its velocity, and then used a web resource to obtain the total distance in the horizontal and vertical Read More...

Studying Paragliding Using ArcGIS Explorer: Determining Total Horizontal Distance and Velocity

We have been examining how one might study sports such as paragliding in 3-D using ArcGIS Explorer. We mapped the GPS track of the paraglider, and how to calculate vertical change and vertical velocity. Let us now calculate the total flight length. As Read More...

Studying Paragliding Using ArcGIS Explorer: Calculating Vertical Change

I recently discussed how one might map and study a 3-D sport such as paragliding using ArcGIS Explorer. Mapping paths in the horizontal and vertical dimensions is just one of many interdisciplinary activities possible from paragliders or any other object Read More...

As 3D As It Gets: Studying Paragliding Using ArcGIS Explorer

Many activities are inherently spatial in nature. Paragliding is an activity in which a person flies in a harness suspended by lines below a large fabric wing. The lack of a motor and complete dependence on the environment makes paragliders extremely Read More...

Mapping An Airline Route

After boarding an airplane after the National Science Teachers Association’s annual convention, I recorded the position of the aircraft as it flew along on my GPS receiver. I held the GPS at the window, and before we landed, I saved the positions it automatically Read More...

Using ArcGlobe To Analyze Earthquakes in 3D

ArcGlobe, part of ArcGIS’ 3D Analyst extension, is a useful tool for education. I recently described how to model population change in ArcGlobe. Let’s investigate how one might use it to study plate tectonics. To the default image of the world, I added Read More...

Digging Deeper Into Population Change By County Using ArcGlobe

Recently, we have been examining different GIS tools useful for studying population change over time. We began with two-dimensional analysis using ArcExplorer Java Edition for Education (AEJEE), followed by 3D analysis using ArcScene. Let’s turn our attention Read More...

Digging Deeper Into Population Change By County Using the 3D Analyst Extension

We have recently been examining a simple yet powerful topic that can easily be studied with a GIS—population change over time. We have been asking why population change in US counties has occurred, if current trends are radically different than past trends, Read More...
