Tutorial 2: Numpy Arrays

Hello Archaeopy! We will be releasing our Geophysical challenge two next week! To get you ready for this challenge, here is the complementary tutorial covering numpy arrays. We have discussed numpy before in previous posts, but since it is the fundamental package for handling our data, we thought it would be important to cover the numpy basics once more. Much of this tutorial will be taken from the tutorial on the official numpy webpage. Check it out for further information.

Why numpy? 

Numpy's main object is the multidimensional array. Consider geophysical data: we have positional coordinates (x and y) and at least one value (z). There are many ways we can handle this information (e.g. xyz file, grd file, as profiles). Numpy arrays are efficient for handling, storing, and manipulating large datasets.

My first Py

Recently I went out on site and collected two reasonably large data sets which could not be easily handled by proprietary software.  This rather fundamental need to be able to actually use my survey data inspired me to have a go at the first ArchaeoPy challenge and to start to get to grips with the Python language.  Having completed and uploaded some script, I was encouraged by Popefinn and Chrys Harris to share it with you in this post.

Hello Archaeopy! It has been awhile since our last post. It has been a busy past two months full of conferences and fieldwork, but these have inspired upcoming tutorials and challenges! We would appreciate some feedback regarding how ArchaeoPy is administrated. Our new plan is to release challenges monthly (with the next challenge issued next week, on the 17th... so there is still time to complete the first challenge and submit your entry for the mystery prize!) with virtual meetings being held and broadcast every fortnight. Also, what do people think of a mailing list, for the between meeting times, for any questions, comments, or ideas? We will we be sending around invitations to a google group, to those who are subscribed as users. Please let us know in the comments below, on the facebook page, or via tweet what you think of these changes!
