Nice ArcMAP extension allowing for simultaneous comparison of points in Arc and Google Earth. Can be downloaded….search for something like: Arc2Google ArcMAP extension.

Excellent! Making rapid progress on road mapping and validation!! Angelica has done amazing with the Quickbird imagery. Here is a small low resolution subset of our study area.

Finally, the finished river/water mask for a small subset (low res version) around Puerto Maldonado (Peruvian Amazon) in our study area!

Calibration and installation of our sensors. Unfortunately one of our PAR sensors shorted out, will have to send it back to Apogee and have it replaced when we take them down next week.

ScreenClip

one failed but interesting approach to classifying images using hierarchical trees.

ScreenClip2

Multi image stacking that’s been driving me crazy these last weeks. Just completed the first mosaic, 2008, comprised of ~30 images, yes! Running a despeckling program in IDL, hope it looks good.

Here is an example of the core of the despeckler procedure:

ScreenClip3

I’ve been planning to optimize it to run without the use of for loops, however at the moment this is just not necessary given we only have 3 mosaics to run (but it would go from 30 minutes processing time to probably around 30 seconds!).

System for canopy LiCOR measurements. Allows for ground based assistants to lift the LiCOR into the canopy, then fine adjustments via the climber.

System now including the extension for the cuvette head. This version will be cleaned prior to starting measurements on Wed or Thur. I’ll post a photo of the final cleaned setup before we head out.

LiCORing in the rain. Good progress on understory curves. Fixed a mystery leak, hard to track down, but ultimately solved by tightening a few screws around the cuvette head. A matter of 0.8 ppm C02 variation…

  • Job/Post-doc applications.
  • Bolivia analysis.
  • Sensors up and running (took 3 days to set up).
  • Prepping for LiCOR work starting tomorrow through late next week.
  • Road delineation in the Peruvian, Bolivian and Brazilian Amazon.

Have identified nearly 5000 km of roads within our study area in the year 1986. This will also be conducted for 2000 and 2008.

Success. The preliminary version of the image merging procedure is functional. This will allow for highly controlled stacking of SLC-OFF Landsat imagery (2003+).

Image pointers are a great way to define new variables within FOR loops. Crucial for reading in multiple Landsat images of varying ZYZ dimensions.
