Updating Your Mobile OS: The Double-Edged Sword of Updates

Updating Your Mobile OS: The Double-Edged Sword of Updates

This article is aimed at the question of updating or not updating the OS for your mobile mapping device. Ideally, we could all update our devices used for mobile mapping without worrying about any unforeseen software bugs, but that just isn't the case. There will always be the potential for a software bug to inhibit our ability to collect field data with our mobile device. This article focuses on the best practices for determining when and if to complete an OS or mapping software update.

How to Setup Esri's New Collector to Capture Orthometric Heights

How to Setup Esri's New Collector to Capture Orthometric Heights

This how-to workflow is designed for the New Collector from Esri, formerly known as the Aurora project.  This will only capture live Orthometric heights with an Eos Arrow receiver running the Geoid12B in the Eos Tools Pro app.  Doing that will allow Collector points to capture real-time NAVD88 elevations.

The Value of Mobile GIS and the Power of Cloud Computing in Natural Resource Management

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).

RTK GPS Explained

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.

Using Tablets in the Field: A Case Study

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.
