QGIS 3 has landed. When QGIS releases a new version, it’s kinda a big deal. Because the unsung heroes of open source GIS software are back in action! It’s their third big release. QGIS 3! I know some of you may be hesitating to make the switch to QGIS 3. But when you hit a fork in the road, what do you do? You look the devil in the eye and take this ride.
You need geospatial data to do anything with GIS. Data is the fuel for all GIS-based projects. Not long ago, obtaining data for a GIS-based project was an arduous task. Challenges included the lack of data, monetary, licensing, and other restrictions on data, difficulty in obtaining and sharing large data sets given the state of computer technology, and other societal and technical challenges.
You probably grew up using ArcGIS… or QGIS…and every day, you sit down at your computer desk…and you do the same thing: You open up the same ArcGIS software…or QGIS software (albeit a newer version) because that’s what you know best.But have you ever asked yourself,Can I get MORE from using different GIS mapping software?
You don’t have to pay a king’s ransom to map the world. This is because you can do it all with free GIS software.
The best part is: These free GIS software give you the firepower to get the job done as if you’re working with commercial GIS software.
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 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.
Creating a good web map is not an easy task but over the years we’ve seen plenty of amazing geovisualization examples. Almost all of them have been developed with the use of one of the tools, APIs or libraries mentioned below.
