Hi, I am a student, still new and in the process of learning about Spatial. I have a project that requires me to do spatial kriging. But I still do not get the idea of how I should start. I have monitoring air quality data in dailly, monthly and yearly. My question is, to start doing kriging, I have see that we need longitude and latitude, but did I need the latitude and longitude of each dataset?.If I have total data about 500, am I supposed to have 500 of longitude and latitude based on the data? and is there any minimum or maximum of the dataset to get a better result in the kriging? I hope to get a reply from you and thank you in advance. Sincerely, Siti Hasliza

You should post this on the r-sig-geo list rather than here: https://stat.ethz.ch/mailman/listinfo/r-sig-geo That's where expertise on spatial data analysis is likely to reside.

Thank you very much. I will ask the question there. Siti Hasliza

Start with a good book like "Applied Spatial Data Analysis with R". If you want to do spatial data analysis, then you are going to need measurements at lots of different places in space. On Thu, 24 Mar 2022 at 23:14, Hasliza Rusmili <haslizarusmili at gmail.com> wrote:

For spatial predictive modeling in kriging, many reproducible examples on data sampling and preparation, parameter optimization, accuracy assessment, and the generation and visualization of spatial predictions have been provided in a book "Spatial Predictive Modeling with R". The outline of this book was published at: https://www.mdpi.com/2076-3417/9/10/2048. Four R packages (i.e., spm, spm2, steprf and stepgbm) for the book, with many reproducible examples, are also available on CRAN. Hope this helps.
