Whitebox GAT Usage

Check out Prof. John Lindsay’s open-access GIS project – Whitebox GAT. It is an outstanding GIS software package with a lot of advanced geoprocessing tools!
http://www.uoguelph.ca/~hydrogeo/Whitebox/

Whitebox Geospatial Analysis Tools

It is difficult to get reliable information about the usage of open-source software like Whitebox GAT. With the recent release of Whitebox 3.4 ‘Montreal’, I decided to undertake an analytical exercise to try and figure out where Whitebox GAT is being used based on some download information that I had accumulating in my inbox. This work updates a previous survey that I carried out a number of years back, shortly after the 1.0 release. Examining nearly 21,000 downloads of the software, I discovered the following:

  • Whitebox GAT has been downloaded in at least 178 counties worldwide, with the top 10 countries, in terms of number of downloads, being the United States, Canada, India, Italy, South Africa, the United Kingdom, Germany, Brazil, Australia, and Spain.
  • Whitebox GAT has been downloaded in 5149 cities around the globe. The map below shows each city in which Whitebox GAT was downloaded at least one time over the…

Invitation to participate in AWRA 2017 Special Session on GIS/RS approaches to aquatic connectivity

connectivity

Dear Colleagues,

Dr. Melanie Vanderhoof and myself are proposing a Special Session for the AWRA 2017 Specialty Conference, focused on Aquatic System Connectivity, and we would like you to consider giving a talk within our Special Session (www.awra.org/meetings/Snowbird2017). This conference will be held April 30 – May 3, 2017 in Snowbird, Utah. Our proposed session is entitled, “Using GIS and remote sensing approaches to inform aquatic system connectivity.” A summary of the Special Session is below. Conference organizers are requesting that we confirm at least a partial list of Special Session participants prior to submitting our session proposal, hence our invite.

If you are thinking of attending the conference and would like to tentatively commit to giving a talk in our Special Session then please send Melanie and myself an email with a draft topic or title.  We are hoping to receive responses within the next 2 weeks, or by October 10, 2016. Also please forward this invite to others for which it may be relevant.

We are loosely coordinating our session with another proposed Special Session, “Tackling connectivity through cross-scale integration: Lessons learned in the Prairie Pothole Region” organized by Laurie Alexander, Renée Brooks, and Jay Christensen with USEPA.

The conference organizers have requested that we let you know that all speakers must pay the registration fee. Regardless it looks to be a great conference and we look forward to hopefully seeing many of you there!

Best Wishes,

Melanie Vanderhoof and Qiusheng Wu

Special Session Title: Using GIS and remote sensing approaches to inform aquatic system connectivity

Special Session Description:

This session will focus on approaches that use GIS and remote sensing to inform hydrological, geochemical and biological connectivity on a watershed to landscape scale. This session seeks to explore connectivity at a coarser scale than measurements at individual sites. GIS can provide spatially explicit predictions of connectivity at a landscape scale, while remote sensing datasets can, in turn, provide predictions of surface depressions, flow paths, and help quantify variability in surface water extent and arrangement. This data can be used to directly predict and bound estimates of landscape-scale surface water connectivity as well as inform and validate hydrological and geochemical models of aquatic connectivity.

Setting up Anaconda, PySAL with ArcGIS Python environment

This tutorial shows you how to set up conda environment to work with ArcGIS 10.4 and ArcGIS Pro 1.3. You can download a pdf copy of the tutorial with screenshots HERE. At the 2016 Esri International User Conference in San Diego last month, Esri released ArcGIS Pro 1.3, which can now use conda for packaging Python libraries. This allows support of python under multiple Python environments. You no longer need to install a separate Python install to get the full Python capability with ArcGIS as you did with past versions.

Workflow to set up Anaconda with ArcGIS 10.4

  • Install Anaconda without fouling the Windows environment (paths, registry) to break Esri’s python stack
  • Configure Anaconda with the particular add-ons you want, and
  • Configure ArcGIS’s Python so that it is aware of the appropriate Anaconda content.

1) Install Anaconda for All Users

  1. Go to http://continuum.io/downloads
  2. Download the 32-bit version of Anaconda (Python 2.7)
  3. In the install dialogs:
    • Select install for All Users
    • conda01
    • Install to a folder by default (C:\Anaconda2)
    • conda02
    • IMPORTANT: To avoid breaking ArcGIS (or other software), uncheck the checkboxes (a) make Anaconda the default Python and (b) add Anaconda’s Python to the PATH.
    • conda03
  4. Go to Start > All Programs(apps) > Anaconda2(32-bit) > Anaconda Prompt. Right click, run as administrator

2) Configure an Anaconda environment for use with ArcGIS

  1. Find the versions of numpy and matplotlib ArcGIS is using.

Open ArcMap and its Python window, and enter these commands:

    • >>> import sys, numpy, matplotlib
    • >>> print(sys.version, numpy.__version__, matplotlib.__version__)
    • (‘2.7.10 (default, May 23 2015, 09:40:32) [MSC v.1500 32 bit (Intel)]’, ‘1.9.2’, ‘1.4.3’)
    • conda04
  1. Create an Anaconda environment that is compatible with ArcGIS
    • Get to the Anaconda Command Prompt (Start > All Programs(apps) > Anaconda2(32-bit), pick “Anaconda Prompt“), Right click, Run as Administrator.
    • Type (depending on ArcGIS version, I am using ArcGIS 10.4 as an example here):
    • “conda create -n arc104 python=2.7.10 numpy=1.9.2 matplotlib=1.4.3 pyparsing xlrd xlwt pandas scipy ipython ipython-notebook ipython-qtconsole”
    • conda05
    • Enter y to proceed.
    • Anaconda’s conda command will then set up an environment subdirectory, ex: ” C:\Anaconda2\envs\arc104 “, installing the downloaded packages into it.
    • conda06
  2. Test the virtual environment
    • At the Anaconda Command Prompt, type: activate arc104
    • Type: conda list. You can see the list of packages installed.conda07
  3. Add more packages
    • You can add more packages using conda install, but make sure you specify version numbers for these that won’t change the environment’s version of python or numpy (or ArcGIS will not be able to use that environment anymore).
    • Let’s add the Python Spatial Analysis Library (pysal) module.
    • Type the following command at the Anaconda Prompt:”conda install -n arc104 python=2.7.10 numpy=1.9.2 matplotlib=1.4.3 pysal”
    • conda08

3) Configure ArcGIS to see Anaconda and vice versa

  1. Anaconda Python to ArcPy
    • Copy the Desktop10.4.pth file to the Anaconda environment site-packages folder:
    • From: C:\Python27\ArcGIS10.4\Lib\site-packages\Desktop10.4.pth
    • To: C:\Anaconda2\envs\arc104\Lib\site-packages\Desktop10.4.pth
  2. Arcpy to Anaconda Python
    • Create a zconda.pth (path) file with the content “C:\Anaconda\envs\arc104\lib\site-packages” in it.
    • Then copy zconda.pth to C:\Python27\ArcGIS10.4\Lib\site-packages
  3. Testing in ArcMap
    • As a regular user, start ArcMap, open the Python window
    • type “import pysal”
    • type “pysal.” A popup menu with a list of pysal-provided functions is a pretty good sign the installation succeeded.
    • conda09
  4. Testing in PyCharm
    • Start PyCharm, in File\Settings…, choose Project then Project Interpreter
    • Ignore the drop down list for Project Interpreter, and click the cog button to Add Local, and in the file browser pick C:\Anaconda2\envs\arc104\python.exe
    • conda10
    • To run your script, right click it in the Project window, and choose either Run or Debug
    • Restart PyCharm for the Python Console to use the arc104 environment.
    • conda11

Workflow to set up Anaconda with ArcGIS Pro 1.3

1) Create an Anaconda environment that is compatible with ArcGIS Pro

  • Copy the folder arcgispro-py3 from C:\Program Files\ArcGIS\Pro\bin\Python\envs and paste to C:\Anaconda2\envs
  • Rename the copied folder arcgispro-py3 in C:\Anaconda2\envs to arcpro

2) Test the virtual environment

  • At the Anaconda Command Prompt, type: activate arcpro
  • Type: conda list. You can see the list of packages installed

3) Add more packages

  • Let’s add the Python Spatial Analysis Library (pysal) module.
  • Type the following command at the Anaconda Prompt:”conda install pysal”

4) Configure ArcGIS to see Anaconda and vice versa

  • Arcpy to Anaconda Python
    • Create a zconda.pth (path) file with the content “C:\Anaconda2\envs\arcpro\lib\site-packages” in it.
    • Then Copy zconda.pth to C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages
  • Testing in ArcGIS Pro
    • Start ArcGIS Pro, open the Python window
    • type “import pysal”
    • type “pysal.” A popup menu with a list of pysal-provided functions is a pretty good sign the install succeeded.
    • conda12
    • conda13
  •  Testing in PyCharm
    • Start PyCharm, in File\Settings…, choose Project then Project Interpreter
    • Ignore the drop down list for Project Interpreter, and click the cog button to Add Local, and in the file browser pick C:\Anaconda2\envs\arcpro\python.exe
    • conda14
    • To run your script, right click it in the Project window, and choose either Run or Debug
    • Restart PyCharm for the Python Console to use the arcpro environment.

New article on sinkhole detection published in Geomorphology

My new peer-reviewed article titled “Automated delineation of karst sinkholes from LiDAR-derived digital elevation models” has been published in the latest issue of Geomorphology. You can download a free online copy using this link: http://authors.elsevier.com/a/1T3d9_,Oh6mAl8 (expires on July 8, 2016). In this paper, we present a localized contour tree method for automated extraction of sinkholes in karst landscapes. The study area was Fillmore County in southeastern Minnesota, USA. See some figures below:

NASA and Japan make ASTER imagery available for free

Source: http://goo.gl/f9ECIG

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of the instruments on NASA’s Terra satellite. Although it is a NASA satellite, the instrument belongs to Japan’s Ministry of Economy, Trade and Industry (METI). The instrument was launched in 1999 and has captured more than 2.95 million individual scenes since then. On the first of April this year NASA announced that the full catalogue of imagery is being made available to the public at no cost. The instrument, amongst other things, takes stereoscopic images that enables it to calculate altitudes albeit rather low resolution. The elevation data has always been available to the public at no cost.

The most interesting images have been collected in a gallery found here. You can also see some of the more interesting images in this article and this one.


Mt. Etna, when it erupted in July 2001. The full resolution image and description can be found here.


This image shows the 3D capabilities of ASTER. The full resolution image and description can be found here.

To access the full database of imagery, you can use the MADAS (METI AIST Data Archive System). A really nice feature is that it allows you to download the images as network-linked KML files.

The imagery has a similar resolution to Landsat imagery (approximately 30 m per pixel), so is really only suitable for viewing large scale phenomena. As with Landsat imagery its best use would be to see current events before other satellite imagery becomes available. In December last year we used Landsat imagery to look at the scar made by a tornado near Holly Springs, Mississippi. We found it relatively easy to find an ASTER image of the same region captured on March 28th, 2016, and the scar is still visible. Download this KML file to view it in Google Earth.


The image only covers a small part of the tornado’s track.
