GPS Receivers for GIS Data Collection

June 22, 2009By

In my column earlier this month, I discussed the use of consumer GPS receivers for GIS data collection. Remember the analogy I used?a Volkswagen Beetle wasn?t designed to run in a Formula One race? This column is going to focus on the Formula One cars, not the Volkswagen Beetles. In other words, it will focus on the GPS receivers on the market that are designed for GIS data collection. I will refer to them as GPS/GIS receivers. read more

Survey Perspectives: RTK Networks Webinar Q&A Follow-Up

May 6, 2009By

Many surveyors I know use RTK for setting boundaries. Some even use single-baseline RTK for this task, which is essentially just a radial survey (no redundancy). I?d say that almost all whom I know that are doing this have used their RTK systems enough to understand the limitations. In fact, I think most have run RTK and total stations side-by-side on jobs to gain confidence and understand RTK in the field. read more

Survey Perspectives: RTK Networks: The Wild, Wild West

April 1, 2009By

What can you say about RTK Networks, except wow! They have popped up everywhere and continue on a path of rapid growth. In the last five years, I'd say it's clear that two GNSS technologies have changed the survey/construction industry more than any others; machine control and RTK networks. read more

Survey Perspectives: About Alaska

March 2, 2009By

I wish I could share with you what I'm seeing right now. I'm on a scenic train in Alaska, traveling from Anchorage to Fairbanks. From someone who usually travels by air, scurrying through airport security at the last minute, this is the way to travel...truly relaxing. The special cars of the Alaska Railroad are built with large picture windows for soaking in the scenery. The train will stop for residents who flag it down and need a ride to the next town. The conductor will even stop the train for picture-taking if the view warrants, which it did when we saw a wolf trying to chase down three sheep on a rock slope along a river. read more

Survey Perspectives: What’s Your Occupation Time?

February 3, 2009By

A reader wrote me about occupation times for RTK work, and it's spurred a conversation I think will be interesting to you and perhaps a little controversial. It seems that most GPS/GNSS users have developed their own opinion based on their own experience. read more
