book finally in store

Our book “Remote Sensing and GIS for Ecologists – Using Open Source software” is now available. First copies arrived and it looks pretty good. Great to have finally a copy on our desks after all the writing, testing and editing! We hope that you enjoy it as much as we do and that it helps you working with remote sensing and GIS in your research topics.

remote-sensing_gis_ecology_book_Wegmann_Leutner_Dech_2016You can order it here.

All practical examples in this book rely on OpenSource software and freely available data sets. Quantum GIS (QGIS) is introduced for basic GIS data handling, and in-depth spatial analytics and statistics are conducted with the software package R.

Readers will learn how to apply remote sensing within ecological research projects, how to approach spatial data sampling and how to interpret remote sensing derived products. We discuss a wide range of statistical analyses with regard to satellite data as well as specialised topics such as time-series analysis. Extended scripts on how to create professional looking maps and graphics are also provided.

This book is a valuable resource for students and scientists in the fields of conservation and ecology interested in learning how to get started in applying remote sensing in ecological research and conservation planning.

updated RStoolbox version 0.1.4

The RStoolbox R package has been updated after some testing in courses and by colleagues. Please update your package using update.packages() or install the RStoolbox again.

New functions are:

  • new function `validateMap()` for assessing map accuracy separately from model fitting, e.g. after majority or MMU filtering
  • new function `getValidation()` to extract specific validation results of superClass objects (proposed by James Duffy)
  • new spectral index NDVIc (proposed by Jeff Evans)
  • new argument scaleFactor for `spectralIndices()` for calculation of EVI/EVI2 based on scaled reflectance values
  • implemented dark object subtraction radCor(..,method=’sdos’) for Landsat 8 data (@BayAludra, #4)

various changes were applied:

  • superClass() based on polygons now considers only pixels which have their center coordinate within a polygon
  • rasterCVA() now returns angles from 0 to 360° instead of 0:45 by quadrant (reported by Martin Wegmann and explained here)

  • improved dark object DN estimation based on maximum slope of the histogram in `estimateHaze` (@BayAludra, #4)

And some bugs fixed:

  • superClass() failed when neither valData or trainPartition was specified. regression introduced in 0.1.3 (reported by Anna Stephani)
  • spectralIndices() valid value range of EVI/EVI2 now [-1,1]
  • radCor() returned smallest integer instead of NA for some NA pixels
  • fix ‘sdos’ for non-contiguous bands in radCor (@BayAludra, #4)

we uploaded and linked all data sets used in our book on the “data” page of our webpage. Cropped Landsat data as original as well as pre-processed files can be downloaded. Moreover a variety of vector files and final products created in the chapters are available. Download the data here.

final electronic proof

remote_sensing_GIS_ecology_open_source_Wegmann_Leutner_Dech_Oct2015We received the final electronic proof of our book “Remote Sensing and GIS for Ecologists – Using Open Source software“. The printed versions of our book should be available soon and we are very much looking forward to it.

The publisher is still offering 20% discount on pre-orders – order our book right now on www.pelagicpublishing.com using the discount code: RSGE20.

 

We are also thankful to Woody Turner for his fantastic foreword:

“.….With this book, Wegmann, Leutner, and Dech […] cleverly couple an exploration of satellite remote sensing with step-by-step immersion in the open source GIS and statistical analysis tools that allow one to make sense of the remote sensing products. In my experience, this book is unique in walking the ecological reader through the actual steps necessary to create their own remotely sensed products. It is more than an introduction to the principles of remote sensing and GIS. It is guide to get the reader going, and using remote sensing and GIS to create focused products. The text also helpfully points to selected websites, articles, and books for deeperbook_remote_sensing_gis_ecologists_wegmann_leutner_dech informational dives and recommends ways to connect with the geospatial community. I applaud the authors for advancing all ecological disciplines with this text. Through this guidebook, they open the doors to the geospatial revolution that is taking our science and its applications to new heights.

book soon available – discount for pre-orders

RS_GIS_Ecology_Book_Wegmann_Leutner_Dech_adOur book “Remote Sensing and GIS for Ecologists – Using Open Source software” will soon be available. We worked through the 3rd proof and fixed all remaining issues. Looking forward to the printed version. The book offers a great overview of Remote Sensing applications using Open Source software, mainly R but also QGIS and provides you with working code to practically redo the analysis outlined in the book. The new RStoolbox R package which has been developed in parallel to the book is used extensively.

Update: R spatial handling cheatsheet

RemoteSensing_GIS_spatial_R_cheatsheetWe updated our cheatsheet on spatial data handling in R. Beside some minor changes of common raster commands we also added now some of the new RStoolbox commands within a Remote Sensing operations section such as the command for supervised classification, fractional cover analysis or cloud masking.

The R spatial data handling cheatsheet has been created to ease the use of relevant R commands and cen be  downloaded as pdf.

Copyedited proof is submitted

The copy-edited proof of our book “Remote Sensing and GIS for Ecologists – Using Open Source software” is finally done and we just need to fix some issues with the image colouring. We are positive that the printed version will be available later in October or early November.

Also the package “RStoolbox” which is used extensively in this book has just been accepted by CRAN and can now be downloaded using “install.packages(“RStoolbox)” – more details here.
