Democratization of Geospatial Data with Real ROI



By George Demmy



It’s easy to fall into a trap of considering data for data’s sake. Knowledge is power, after all, and by democratizing data; you spread power to more places and more people.

To what end? When an organization considers the means to acquire, analyze and present data, the investment has to be driven by both its cost and its impact on the bottom line. By performance, more than power. In this case, performance means the Return-on-Investment (ROI) in democratized data.

The military faces this challenge regularly in its goal of making personnel “human sensors,” adding what they see on the ground, in front or behind them in real-time, to satellite and unmanned aerial system sensors to provide situational awareness to commanders miles or even continents away who are making life-or-death decisions.

In industry’s case, decisions can make or break a company and careers, and those decisions have a goal. In his blog, Michael McCarthy writes, “investing in democratizing data needs to have a wide range of influence over many decisions across the organization … The objective is to excel at decision-making. The reason for doing this (in business) is to realize revenue growth.”

He adds, “More emphasis needs to be placed on making better decisions faster and identifying the data needed to support those decisions, and not the other way around.”

That’s why TerraGo created OpenGeoPDF – to combine the latest, most appropriate geospatial and IT standards, practices and capabilities to extend the reach of GIS to the widest possible audience. These capabilities include a bi-directional relationship with field operations that can offer decision-makers a better sense of situational awareness than data limited to that normally available at headquarters. It can do so with mobile data input and decision reception from an iPhone or Android device.

This audience can then drive decision-making away from the realm of the “gut” and the limitations of company policy to allow managers to adapt to changing times. Data to support these decisions can be more up to date and adaptable to operational environment ebb and flow. Data behind the presentation maps can drive other decisions, as well as creativity and innovation in areas not imagined when the data was harvested. That’s democratization.

Measuring return on investment in GIS is easy enough if you limit it to reducing time-to-customer and man hours saved with the capability. But what about savings attributable to using data available to a wider range of people within an organization and the impact on revenue and market share growth? On measuring efficiencies vs. opportunities?

On attracting and retaining employees at decision-making and information-gathering levels because they see the “why” in the work they are hired to do, rather than just the less-rewarding and often-frustrating “what?” Those metrics can be softer and more elusive, but they are no less real or of diminished importance in cost-benefit analysis that drive ROI.

TerraGo OpenGeoPDF Products: Version 6.7



By George Demmy



TerraGo has just released the version 6.7 of most of our core products which focus on bringing GIS-Lite functionality to document workflows under the aegis of our OpenGeoPDF initiative. That’s a mouthful, so I guess it wouldn’t be too bad to shorten it to version 6.7 of our OpenGeoPDF products. In this release, we’ve added two functions which significantly enhance the GIS-Lite capabilities provided by the recently-added Identify tool in Toolbar: search and update of GeoPackage feature attributes.

Search
Search has become an essential paradigm. My once punctilious management of email, each incoming message being tagged and routed to its own place based on an arcane library of rules accumulated over more years than I care to admit in Emacs Gnus has been replaced by a couple of rules for alerting me to things of current urgency, but otherwise I just search to find in an sea of unsorted emails Outlook, at least at work. With Toolbar 6.7, you can search attached GeoPackage for features matching what you type in the search field, get a list of matches, and then you can click the match to see where it is on the map. Double click the match and you’ll zoom to that feature. We had to add additional metadata to the GeoPDF documents to make this all go, and that’s some of what went into Publisher 6.7, including persisting the field names that ArcMap thinks is the most useful to identify a particular feature. Again, using OpenGeoPDF to tie Publisher to its client application Toolbar helps illustrate the connection. I hope Esri clones the feature in their Identify tool — it’s pretty damn useful and cool.


Update
Update of feature attributes in a GIS-Lite application is one of those features that perhaps not that many people need, but for the folks that do, it’s essential. They need coworkers, citizens, people distributed hither and yon to be their eyes and ears and share what they see and where they see it. Our geospatial markup we call GeoMarks have been around since before TerraGo, and they’re handy for the ad hoc observation, but they extend PDF’s annotation system which is not well suited for large amounts of GIS data. GeoPackage feature attributes, however, is perfectly suited for large amounts of GIS data in a document workflow context. Load up 15000 telephone poles and out you go to do your inspection. You may not need to go to each pole, but the several that you do will certainly be in there. Ground truthing, inspections, surveys, the applications are myriad. Search and update are two dramatic steps forward for GIS-Lite capabilities in TerraGo Toolbar made possible by our close integration with ArcMap with Publisher. I can’t think of anything that more dramatically increases the audience and utility of an investment in ArcGIS at the price point and ease of use threshold. If you can, please let me know!
