Zesty Blogisty: Destination point given distance and bearing from start point
http://thezestyblogfarmer.blogspot.com/2013/07/destination-point-given-distance-and.html
Unleash your inner geek. Wednesday, 24 July 2013. Destination point given distance and bearing from start point. A list of x-coordinates (longitudes). A list of y-coordinates (latitudes). The number of samples in the plane towards the destination point. A list of headings (degrees). A list of distances in two directions (metres). This is how you find the coordinates (x, y) along the plane defining a starting point and two end points, in MATLAB. Subscribe to: Post Comments (Atom). A cooler shell prompt.

Unleash your inner geek. Sunday, 20 January 2013. Patchwork quilt in Python. Data' is a Nx2 numpy array of [x,y] points. Numsegs' and 'numclass' are integer scalars. The greater these numbers the greater the 'complexity' of the output and the longer the processing time. Some example outputs in increasing complexity:. Subscribe to: Post Comments (Atom).

Unleash your inner geek. Wednesday, 16 January 2013. Compiling Clarkson's Hull on Fedora. A note on compiling Ken Clarkson's hull. Program for efficiently computing convex and concave hulls (alpha shapes) of point clouds, on newer Fedora. First, follow the fix described here. Which fixes the pasting errors given if using gcc compiler. Then, go into hullmain.c and replace the line which says:. At the end of the function declarations (before the first while loop).

Zesty Blogisty: Doing Spectral Analysis on Images with GMT
http://thezestyblogfarmer.blogspot.com/2013/08/doing-spectral-analysis-on-images-with.html
Unleash your inner geek. Wednesday, 14 August 2013. Doing Spectral Analysis on Images with GMT. Mostly an excuse to play with, and show off the capabilities of, the rather fabulous Ipython notebook! I have created an Ipython notebook to demonstrate how to use GMT to do spectral analysis on images. This is demonstrated by pulling wavelengths from images of rippled sandy sediments. This also requires the convert. Facility provided by Image Magick. Another bodacious tool I couldn't function without.

Zesty Blogisty: Kivy python script for capturing displaying webcam
http://thezestyblogfarmer.blogspot.com/2013/10/kivy-python-script-for-capturing.html
Unleash your inner geek. Saturday, 12 October 2013. Kivy python script for capturing displaying webcam. Is very cool. It allows you to make graphical user interfaces for computers, tablets and smart phones . in Python. Which is great for people like me. And you, I'm sure. And it's open source, of course. Right, it detects and displays your webcam on the screen, draws a little button in the bottom. When you press that button it takes a screengrab and writes it to an image file. Voila! 21 July 2016 at 09:12.

Zesty Blogisty: Coordinate system conversion using cs2cs from PROJ
http://thezestyblogfarmer.blogspot.com/2013/03/coordinate-system-conversion-using.html
Unleash your inner geek. Friday, 8 March 2013. Coordinate system conversion using cs2cs from PROJ. I hate geodesy. It's confusing, multifarious, and ever-changing (and I call myself a scientist! But we all need to know where we, and more importantly our data, are. I have need of a single tool which painlessly does all my conversions, preferably without me having to think too much about it. You could use an online tool. Sudo apt-get install proj-bin. In Fedora I searched yum for proj-4. If the man page.

Unleash your inner geek. Saturday, 12 October 2013. Simple Python script to write a list of coordinates to a .geojson file. This has probably been done better elsewhere. But here's a really simple way to write a geojson. File programmatically to display a set of coordinates, without having to bother learning the syntax of yet another python library. Geojson is a cool little format, open source and really easy. Subscribe to: Post Comments (Atom). Pymix fix: short note on compiling PyMix on Ubuntu.

Unleash your inner geek. Saturday, 26 January 2013. Automatic Clustering of Geo-tagged Images. Part 2: Other Feature Metrics. In the last post. I took a look at a simple method for trying to automatically cluster a set of images (of Horseshoe Bend, Glen Canyon, Arizona). Some of those picture were of the river (from different perspectives) and some of other things nearby. In this post I look at 5 methods using the functionality of the excellent Mahotas.

Unleash your inner geek. Monday, 4 February 2013. Compiling points2grid on Fedora with g. Gridding large [x,y,z] point cloud datasets. Matlab and python have both failed me with their inefficient use of memory. So I'm having to turn to other tools. Is a tool, written in C , which promises to do the job in a simple intuitive way. It accepts ascii and las (lidar) formats and outputs gridded data, plus gridded data densities. That had a working link. I installed this by issuing:. As a rule of thumb, set the.
