Radiocarbon dating price
All colour dyes have limited lifetimes since their molecules break down under the influence of temperature, light and reaction with adjacent materials in the layers in the film.The cyan dye which is responsible for the red colour in an image was especially unstable in films manufactured prior to new developments in the mid-1980's.It is the goal of Air Photo to deal with this kind of image within the limits of the data and the financial limits of most archaeological institutions and private investigators by non-photogrammetrists.Air Photo provides a useful tool for archaeologists (and others) without large amounts of money to spend on user-hostile photogrammetric hardware or expensive software which will enable them to deal with a reasonable number of the many aerial images which have accumulated over the years using modest PC's and peripherals.
However, there is always a small remaining amount even in the most expensive lenses.
ARK the Archaeological Recording Kit is an opensource, standards compliant, web-delivered system for the creation, storage, manipulation and publication of archaeological data and media.
Or in fewer words, it’s a system you can use to put your archaeological data on the web so that you can work on it and share it.
We offer an easy to use Web site that allows researchers from around the world to make use of an integrated framework in which to interpret both radiocarbon data and a priori chronological information.
Bchron is an R package that enables quick calibration of radiocarbon dates under various calibration curves (including user generated ones); Age-depth modelling as per the algorithm of Haslett and Parnell (2008); Relative sea level rate estimation incorporating time uncertainty in polynomial regression models; and non-parametric phase modelling via Gaussian mixtures as a means to determine the activity of a site (and as an alternative to the Oxcal function SUM).
