Map Scale: Scale Bar, Inset Map and Ratio Text

There are several ways to help readers understand distance and map scale. Maps are generally never the same scale as the real world. This is why cartographers use scale bars that compares a map distance to an actual distance.

Not only do scale bars, ratio and stated scales can also show size and distance in a way that people understand, but inset maps help understand map scale.

The GIS Software Landscape

The GIS software options out there seem endless. ArcGIS, QGIS, GRASS GIS, SuperGIS, SAGA GIS, JUMP GIS… The range of GIS products to choose from can get a bit “ridiculous” at times. Don’t worry. You map out solutions to real-life problems every day. You just need someone to map out the GIS software landscape for you.

The Power of Geo-Apps

With billions of users worldwide, Apps are a technology trend that has captured the world’s attention. Online maps provide the information that powers the use of GIS. And every map has an interface—a user experience for putting that map to use. These experiences are Apps, and they bring GIS to life for users.

These Five Maps Will Change the Way You Think About Real Estate

We’ve all heard the mantra: location, location, location. But the most successful real estate companies understand that real value comes from not only location but also insight and timing. You already know where your properties are located and what’s happening around them, but are you making the most of that knowledge? From commercial to residential and beyond, these five maps — and the technology used to create them — will change the way you think about real estate.

landsat data


The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. On July 23, 1972 the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat. The most recent, Landsat 8, was launched on February 11, 2013. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, urban and regional planning, surveillance and education, and can be viewed through the USGS ‘EarthExplorer’ website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from 15 to 60 meters; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wide (or 100 nautical miles long and 100 nautical miles wide, or 185 kilometers long and 185 kilometers wide).

What Makes A Good GIS Question?

Good geographic information system (GIS) questions are not easily created. They can be mysterious to some, unknown to others and cause others to scratch their heads in curiosity. Since most questions posed to GIS are relatively simple – where is this? Most users have their answers satisfied and move on. But a much smaller number of people seek answers to more complex questions that are not immediately available – or even understood.
