This is not a post about Hexagon Geospatial’s Power Portfolio 2015 (we hope to have an interview about this year’s update in the coming weeks). Instead it is a post about their new video ads.
They have taken our love of infographics and created something great. But it isn’t just the graphics, it is also the quick, approachable story that utilizes the approach that good infographics do so well. So far there are two video ads available (Power Portfolio and Producer Suite), but I hope there are more coming next week.
If anyone from Hexagon Geospatial is reading, it would be great if you redo the narration after the ad campaign and release them as general geospatial technology videos that could be used in classrooms and informal ed outlets…just a thought.
OpenDataPhilly.org is undergoing a redesign thanks in part to grant funding from the Knight Foundation. In anticipation of the relaunch of Philadelphia’s newly designed data portal, Azavea invites submissions of visualizations of Philadelphia’s open data.
The OpenDataPhilly Visualization Contest calls on designers, data scientists, developers and anyone who enjoys exploring and visualizing open data. You are invited to share your data visualization that utilizes open data found on OpenDataPhilly.org. Your visualization can be static or interactive and may include maps, infographics, charts or any other creative visualization of data.
Visualizations that represent creative and visually impactful uses of Philadelphia’s Open data will be selected to be featured on the new OpenDataPhilly website (to be launched in late 2014).
Up to 10 data visualizations will be selected to be featured on OpenDataPhilly’s new website. Prizes include $500 in Amazon gift cards to be divided among winners. Additional data visualizations may be selected for display on the OpenDataPhilly web site but only a maximum of 10 will receive prizes. The contest is international and open to anyone. The data visualization must use open data available on OpenDataPhilly.org. The deadline to submit is Sunday, November 30th 2014 11:59pm.

Boundless partners are an important part of spreading the depth and breadth of our software around the world. In this ongoing series, we will be featuring some of our partners and the ways they are expanding the reach of our Spatial IT solutions.
Geospatial Enabling Technologies (GET) was established in 2006 with the vision of becoming one of the leaders for Spatial IT solutions and services in Greece as well as more broadly in Europe and Africa. Specializing in the field of geoinformatics, GET provides robust solutions for both the public and private sector.
Since 2010, GET has deployed and supported OpenGeo Suite as part of their projects. From the very beginning, GET held a strong belief that Boundless was the premier provider for commercial open source spatial software. Through its partnership with Boundless and the use of OpenGeo Suite, GET has been able to implement projects for private companies as well as public authorities and government agencies in Greece including the Hellenic Regulatory Authority of Energy and the Greek Ministry of Agriculture. GET has also offered technical support, via the GET SDI Portal, to many public agencies like the Environmental Protection Agency of Athens and the Military Geographic Institute of Ecuador.
“With the goal to provide advanced geospatial solutions based on open source, we consider Boundless an essential, valuable partner with whom we could design and implement projects effectively,” said Gabriel Mavrellis of GET.
This successful partnership derives from a relationship where each organization greatly benefits by sharing knowledge, expertise, opportunities, and vision. The developers and project managers at GET deploy projects based on OpenGeo Suite and share their knowledge and expertise with Boundless through the implementation and maintenance of solutions in Greece and abroad.
GET has successfully organized training seminars on OpenGeo Suite to provide Greek engineers and developers with a greater familiarity of the platform and its functions. GET is also a proud contributor to QGIS, providing training and translating a large part of the QGIS user interface into Greek.
If you’d like your company to be considered for our international network of partners, please contact us!

Any GIS professional who’s been paying attention to the professional chatter in recent years will be wondering about QGIS and whether or not it might meet some or all of their needs. QGIS is open source, similar to proprietary GIS software, runs on a variety of operating systems, and has been steadily improving since its debut in 2002. With easy-to-install packages, OpenGeo Suite integration, and reliable support offerings, we obviously see QGIS as a viable alternative to proprietary desktop GIS software such as Esri’s ArcGIS for Desktop.
But will it work for you? The short answer is: most likely yes for visualization of most formats of spatial data, probably for analysis of raster and vector data, probably for geographic data editing, and probably for cartographic publishing. Those are all very subjective assertions based on my personal experience using QGIS for the past seven months but I have been using proprietary GIS for over fourteen years as an analyst and cartographer and have written a couple of books on the subject.
By all means give QGIS a try: download and install it, drag-and-drop some data into it, and give it a spin. This is definitely a good time to evaluate it and consider adopting it across your organization.
In this first post, I’m going to focus on visualizing spatial data in QGIS. These basic functions are straightforward and easy to do in QGIS:
moving datasets up and down in the layer hierarchy
zooming around the map
selecting features based on simple point-and-click
selecting features based on complex selection criteria
creating graduated color schemes
In fact, QGIS is an effective means of viewing and exploring spatial data of almost any type. If you have complex data, you might be interested to hear that the newest release of QGIS boasts very fast, multi-threaded, rendering of spatial data that may even make it faster than leading competitors. When I began creating the map shown above, I accidentally added all of the Natural Earth 1:10m Cultural Vectors in triplicate to the project, causing some minor heart-palpitations as I realized it was going to try to render close to 100 vector layers all at once. However, my fears were unfounded as it took only a few seconds for them to render once they were all added. In the realm of visualization, it does most of the other tasks that a GIS professional would expect as well, including support for custom symbol sets (in SVG format). Adding GeoJSON data is simple, just drag a geojson file onto the Layers list. Here, we show a portion of James Fee’s GeoJSON repository of baseball stadiums:
That said, raster visualization can yield unexpected results depending on what is desired. Some raster datasets have tables that associate bands with RGB values such that specific cell-types are rendered certain colors. Often, landcover datasets will have this kind of structure so that, for example, the raster is rendered with blue for water, green for grass, white for ice, and so on. Unfortunately, QGIS doesn’t yet support rendering based on associated table files for rasters. Another slight irritation is the continuing use of binary ARC/INFO GRID formats by some agencies who distribute raster data to the public. If you have one of these datasets, QGIS can open it but you must point to the w001001.adf file using the raster data import button.
One of the most important ways to make GIS user-friendly is to support on-the-fly projection. I still remember when projecting on-the-fly became a part of the software that I used to use. It was the end of 1999, and life was so much easier when multiple datasets from multiple agencies in multiple projections could all be jammed together into a single project, producing a map where all the data layers were in the correct projected space. This was because reprojecting not only added extra steps requiring you to reproject everything into a common coordinate system even if all you wanted to do was visualize the data, it also meant maintaining multiple copies of the same dataset, which contributed to folder clutter and using up of valuable disk space. QGIS supports reprojection on-the-fly but it is an option that must be set in the project properties dialog. Some glitches with projections still seem to occur from time to time. Zooming in, for example, sometimes causes the map to zoom to a different place than expected. However, this unexpected behavior is inconsistent, not a showstopper, and may be fixed soon.
The other important aspect of visualizing data is having enough underlying context for the data. Country boundaries, city labels, roads, oceans, and other standard map data are crucial. Proprietary GIS software generally contains basemap layers that can easily be turned on and off to support visualization in this manner. QGIS also has this capability, in the form of the OpenLayers plugin, which serves up Google, OpenStreetMap, Bing, and Yahoo basemaps at the click of a button. The OpenLayers plugin is free and installs just like any other QGIS plugin—you search for it in the Plugins menu, press “install,” and make your basemap choice in the Web menu.
While QGIS may need a small amount of improvement when it comes to raster visualization and on-the-fly projection, these aren’t hindrances to a typical visualization workflow and are only mentioned here out of respect for a fair and balanced assessment. By and large, my testing has convinced me that the robust visualization capabilities that QGIS offers provide more than enough impetus for many organizations to make the switch to QGIS. In later posts, I’ll discuss how QGIS performs with respect to analysis, editing, and cartography.
