The Value of Mobile GIS and the Power of Cloud Computing in Natural Resource Management
Using Mobile GIS equipment and workflows with cloud computing can streamline data collection and management for field staff and allow managers to make more timely and informed land management and conservation decisions. These workflows also greatly increase the efficiency of reporting. Not only can these solutions save man-hours and money, but also reduce potential human errors introduced by recording field data on paper and then having to manually enter that data into a computer database.

CSU Monterey Bay Tackles High-Accuracy RTK and Elevations with Collector

CSU Monterey Bay Tackles High-Accuracy RTK and Elevations with Collector
To capture horizontal (horizontal datum NAD83) and elevational data (vertical datum NAVD88), the university needed to determine first the required accuracy and if there was an affordable technology solution that could accomplish the task. By working with the GNSS experts at Anatum Field Solutions and their review of Bluetooth GNSS options, the EOS Arrow 200 RTK-GNSS using Esri’s Collector app, paired with an existing campus base station transmitting centimeter-level RTK corrections via the Internet, met all requirements for horizontal accuracy. 

However, they needed to capture the vertical datum in NAVD88. This explains the differences between Height Above Ellipsoid captured by Mobile GIS apps and how to convert that elevation data to MSL (NAVD88).

Galileo Satellite Constellation
The Galileo system will have all brand new cutting-edge satellites technologically comparable to the U.S. GPS satellites and expectedly more reliable than the Russian Glonass satellites.  But the best part is that the Galileo satellites will be able to add more available satellites to receivers capable of tracking more than two constellations simultaneously.

RTK GPS Explained

Posted by Matt on 10/16/2016 to Knowledge Base
RTK GPS Explained
RTK GPS receivers are traditionally very expensive and their accuracy has been thought of as beyond the field mapping needs of most environmental and engineering firms, and government land management groups.  However, with the introduction of Bluetooth RTK receivers for use with field tablets and mobile GIS, RTK’s potential has become less expensive to achieve and much desired.  Add to that the availability of Bluetooth RTK receiver rentals from Anatum Field Solutions, and the continued progression of many companies into mobile GIS workflows with tablets becomes much easier and more affordable.

Mobile GIS: What to do with a GPS Antenna?
One of the things professionals have to get used to when they switch from submeter handheld GNSS equipment to mobile GIS workflows with submeter GNSS receivers is their antenna.  The important thing to keep in mind is the antenna needs to “see” as much sky as possible and preferably at all times.  Below we present a few methods for working with the external antennas used with Bluetooth GPS and GNSS receivers.

Using Tablets For Data Collection to Increase the Efficiency of Aerial Surveys
Recent technological advancements in the form of tablets with mobile GIS software paired through Bluetooth with external GPS receivers are providing new opportunities to aerial surveyors that can substantially increase efficiency and accuracy while simultaneously reducing potential impacts to wildlife.  GPS receivers that we have used include the Arrow 100 for submeter accuracy and the Bad Elf GPS Pro with 2.5-meter accuracy.  The appropriate GPS receiver depends on your projects accuracy requirements.

Using Tablets in the Field: A Case Study

Posted by Matt on 1/18/2016 to Knowledge Base
Using Tablets in the Field: A Case Study
Based on the results of our 2013 and 2014 case studies, we found the quality of data from using the mobile technology likely improved by eliminating potential errors introduced during the manual transfer of data from paper datasheets to an electronic database. The efficiencies gained in the documentation and distribution of the data resulted in substantial cost savings, even when considering some of the upfront costs of training and pre-survey preparation of automated data forms and creation of the Project specific GIS data in the mobile GIS app system. In addition, this technology is extremely adaptable and can be applied to survey data in a variety of disciplines aside from biology, including documentation of cultural resources surveys, geotechnical data, and other engineering data that may be needed for the Project.
