Data Processing

Arghhh, please, not one of THOSE days!!

After spending a beautiful, sunny day in the field gathering geophysical data, the office awaits me. Data must be processed, they said!

There were no problems with the GPR and magnetometry. The site was a nice, even lawn and like a football field. It was a location near the Dutch coast with clear blue skies & fish for lunch. What a way to collect your data!!!

But the problems started the day after.

8.00 am

Euhm, where is my backup USB with the data? Can’t find it. And who took my fieldlaptop this morning?

Please, do not let this happen to me.

Oh, there it is. Pfew

9.00 am

processing GPR data. Hmmm, there are a lot of fielddrains visible in the data. This former soccer field clearly needed draining. I hope it doesn’t obscure my relevant data too much.

Oh, thanks very much, this visual basic software from a previous century keeps crashing. What is wrong, and where is the corrupted file? Checking lots of files one by one.

10.00 am

several  phone calls:

  • ‘yes, sir. We can do that. Oh, you want us to do the survey by the end of this week? Hmmm.’
  • ‘oh, were you expecting the report yesterday?’
  • ‘No, sorry. We can’t go any lower with our costs. Yes, you’re free to look for another geofyzz company.’

11.00 am

Oh, my God. I can’t believe the amount of recent rubble just below the subsurface. This red brick demolition waste is masking my magneto-data. Let’s see if I can fix this. Sigh.

The small archaeological excavations from the 80’s and 90’s do provide additional information, but why do their pits/trenches have to be so visible in my data! Go away!!

13.00 pm

Yep, several of those phone calls you do NOT want to deal with right now.

But just have to.

14.00 pm

Oh great, I have an inbox full of email. Let’s see if some procrastination will make my day.

14.30 pm

Euhmm, do you really want a financial forecast of these projects? You mean as in right now? But…

15.00 pm

postprocessing, filtering, enhancing, gnashing of teeth, munching pencil stubs. Login to GIS failed. Out of memory. Why am I not out in the field? Merrily singing aloud while gathering data. HELP!!

16.00 pm

But WOOT? Is that….yes..the former foundations. Hurray, here they are! And the results from the GPR differ from magnetometry, but combined they give very interesting anomalies.

Let’s make an appointment with the archaeologist to start some interpretation next week.

While humming a joyful tune, I shut down my computer.  Another day at the office. While all the odds seemed working against me today, I obtained some very interesting results.

Big smile!! I do love geofyzz.

Day of data processing – geophysical survey results from Isola Sacra

A day of processing of data, starting with the latest results from the geophysical survey at Isola Sacra, near Fiumicino, Italy.

 

 

This image shows a member of the survey team last year surveying using a fluxgate gradiometer over the central part of the landscape, an area of floodplain between the course of the river Tiber and the small Fossa Traiana, which demarcates the Isola Sacra between Portus and Ostia Antica. So far some 120 hectares of data have been collected, and the latest stage of processing is under way. More to follow later.
