Blue Marble Monthly – September 2017 GIS Newsletter

Satellite Imagery

The Geographic Calculator Edition
Product News, User Stories, Events, and a Chance to Win a Copy of Global Mapper Every Month

Before Global Mapper takes center stage with its pending version 19 release later in the month, we thought it would be a good idea to shift our focus to Geographic Calculator for the month of September. In this edition of Blue Marble Monthly, we showcase an introductory video covering the basic operation of the software and we hear from Sam Knight on the important role that Calculator will play with the introduction of the new North American datum in 2022. As always, a free copy of Global Mapper is up for grabs in the Where in the World Geo-Challenge.

Hurricane Harvey | Blue Marble Calls for Support for Texas

When it was first introduced over two decades ago, Geographic Calculator filled a void in the field of geodesy and became a mainstay for companies and organizations whose business depends on geographic precision. Nowhere was the Calculator more enthusiastically embraced than in Houston, Texas, home to many of the world’s leading energy exploration, extraction, and processing companies. It is with deep sadness that we watch the devastation that Hurricane Harvey has wrought on a region that has become a second home to Blue Marble. While we are confident that the city will recover, the short term needs are immense. For this reason, we strongly encourage the Blue Marble user community to join us in supporting the relief effort. Please donate whatever you can to the Red Cross.


Global Mapper Free for Hurricane Harvey Recovery

Blue Marble is offering free licenses of Global Mapper to any agency or organization that is providing an essential service in response to Hurricane Harvey.

If you are involved in the the clean-up or rebuilding process and you have a need for GIS software, simply email info@bluemarblegeo.com to request a copy of Global Mapper for the duration of the disaster relief effort.

Projections | Are you Ready for NATREF2022 to Replace NAD83?

If there was ever a compelling reason to sit up and pay attention to the discipline of geodesy in general and to the functionality of Geographic Calculator in particular, here it is. In a few years, the folks at the National Geodetic Survey plan to replace NAD83 with the new “North American Terrestrial Reference Frame of 2022”. What does that mean for you? In a recent blog post, Sam Knight, Blue Marble’s Director of Product Management sheds some light on the change.

Did You Know? | Geographic Calculator’s Best Fit Tool

When we consider coordinate systems, we usually assume that they are based on some sort of geographic framework, however this is not always the case. It is common for a localized system to be developed without adherence to a recognized geographic datum. Assuming there is consistency, the system will work fine in a closed environment, however, a problem arises when the inherent data must be referenced to a recognized system. Geographic Calculator’s Best Fit job solves this problem by establishing a geometric relationship between specific locations within the extent of the local data and measured ground control points. With the necessary transformation calculation determined, all other data points in the local system can be accurately converted to the recognized geographic system.

Four down, two to go. So far in 2017, the Blue Marble User Conference (BMUC) has made stops in Calgary, the Washington DC area, Amsterdam, and San Diego. As we approach the last few months of the year, our attention turns to our home state of Maine and our final stop in Los Angeles. BMUC is an informal gathering of geospatial professionals representing a wide variety of industries who share a common interest in Blue Marble’s GIS and geodetic technology. Registration is now open for the final two events of 2017 and space is limited.
