Portable GPS-enabled device market continues to grow
September 18, 2013  by Susan Smith

Findings from ABI Research show that the portable GPS-enabled device market is destined to hold its own because of the growth of dedicated HUD/eyewear, cycling and health/tracking devices. The market was not expected to do as well because of the continuing decline of PNDs, and the growing use of smartphones, smart watches and eyewear.

ABI Research’s quarterly GNSS Database forecasts the new and emerging markets for GPS-enabled devices, and where the opportunities lie in terms of device formats and vertical markets. The report also considers the impact of competitive formats such as smartphone applications, wearable sensors, smart watches, and smart eyewear, providing a complete picture of drivers and inhibitors in this market.

Senior analyst Patrick Connolly comments, “The overall market is forecast to grow from 33.3 million units in 2012 to 36.79 million in 2018, following a brief dip in 2013 as PND declines outweigh growth in other areas. Total revenues will undergo a brief period of fluctuation from 2013 to 2015, before rising to $7.14 billion in 2018.”

Rapid, comprehensive, global satellite coverage is an invaluable asset for responding to major disasters, including earthquakes, tsunamis, floods, tropical cyclones and fires. With five satellites orbiting the globe, DigitalGlobe owns and operates the World’s most agile constellation of high-resolution commercial earth imaging satellites, collects more than 2.5 million square kilometers every day and can revisit the same location daily. Expected to launch in 2014, WorldView-3 will further increase the capability of our constellation with its newly added super-spectral, shortwave infrared (SWIR) and cloud, aerosols, vapor, ice, snow (CAVIS) sensors.

DigitalGlobe’s FirstLook online subscription service for emergency managers and enterprise customers leverages our constellation and DigitalGlobe Cloud Service (DGCS) technology to provide fast, web-based access to pre- and post-event imagery of world events and disasters.   By analyzing the before and after images, DigitalGlobe enables first responders and people on the ground to see the full extent of the situation and effectively plan a course of action following major disasters and events. The collected imagery can be deeply integrated into customer workflows to reduce turnaround time and enable rapid decision making by providing subscription access and standardized data hosting. As we all know, when disaster strikes, there’s no time to waste, so getting this infrastructure set up in advance is critical to a quick response that can often help save lives.

CNIC Navy Energy Program and NSGEM
September 17, 2013  by Amy Hrdlicka

Recently the Navy Shore Geospatial Energy Module went through its fourth successful promotion release in the GeoReadiness Explorer Production environment, and the hype is heating up about it, so I thought I would give everyone a little background on the program and what NSGEM can do….

Commander, Navy Installation Command (CNIC) instated the CNIC Energy Program in order to provide guidance, policy, and tools for implementing mandated energy reduction and sustainability practices.  The main goals of the program (as outlined in OPNAV policy OPNAVINST 4100.5E) are:

  • 50% reduction in energy consumption by 2020.
  • 50% renewable energy source consumption by 2020.
  • 50% net-zero participation by 2020.

Colorado is a semi-arid state, which typically indicates a climatic region that receives precipitation below potential evapo-transpiration, but not extremely. The climate is typically associated with dry winters, wetter springs and summer, highly changeable weather, frequent wind, and the occasional monstrous thunderstorms with damaging hail. Yet, we Coloradans are experiencing catastrophic flood events where, folks on ridges are not free from the reaches of water flowing downhill, from the sky, or from the saturated water table from below. Where has sunny Colorado gone this past week?

Seeing through the trees

Successful mining exploration relies heavily on the accuracy of the geology map layer that depicts the spatial distribution of geologic units and structure. Often times, however, existing geologic maps vary in quality and accuracy due to differences in purpose of mapping, scale or level of details, inconsistency in nomenclatures, and types of map projection/registration. Conventional mapping methods of bringing existing geologic maps to the desired quality level or standard will entail a large amount of time and effort, and consequently will also drastically slow down mineral exploration. The creation of digital geology maps (map components: topography, structure, and lithology) from the desktop using interferometric syntehtic aperture radar (IFSAR or InSAR) provides a cost effective method, espeically in remote dense vegetated areas.

Rise in Geospatial ‘Big Data’ Calls for Solutions for Managing Information Overload
September 13, 2013  by Mladen Stojic, President of Hexagon Geospatial

As an industry buzzword, ‘Big Data’ has reached near ubiquity in nearly every sector, which is completely justified because large amounts of data have become a driving force for any large enterprise.

But just how big is ‘Big Data’?  If we look at the numbers, it can be quite astounding – reinforcing both the challenge and value of leveraging data.

For example, there are 2.7 Zetabytes of data exist in the digital universe today.  In one month, the Library of Congress collected 35 Terabytes of data. Consumer technology giants like Facebook store, accesses, and analyze 30+ Petabytes of user-generated data.  In addition, IDC estimates that by 2020, business transactions on the Internet will reach 450 billion per day.

Preliminary Planning
September 13, 2013  by Ryan Hamilton

As a medium resolution data set the NEXTMap® 5m terrain data plays an important role between high precision ground survey or LiDAR and lower resolution ‘free’ data. This sweet spot is the realm of preliminary planning or site location analysis when a project needs to be defined but not yet calculated. The use of the NEXTMap data during this initial phase may have higher upfront costs, but in the long run, the more precise a preliminary plan is the less re-work you will experience down the line. Site planning is just one of the many applications that the 5 meter data is suited for, and I will jump into others in following posts.
