Great comments. I really enjoy what you mentioned!
The literature uses the phrases which you might come cross in the future, e.g., geographical epidemiology, spatial epidemiology, and medical geography, to describe a dynamic body of theory and analytic methods concerned with the study of spatial patterns of disease incidence and mortality.…[Read more]

The R version may need an update when the package has changed in a way that is incompatible with the version of R you have installed. Glad you find a way to solve the issue. Cheers!

Chawarat Rotejanaprasert replied to the topic Join attributes by loc. (summary) between Distric and Incidence – No spatial idx in the forum Week 2 QGIS 2 years, 10 months ago
Hello, One could use the spatial index for pre-processing which can improve the computing significantly for large datasets. However since our dataset is quite small, it would not matter much without a spatial index for our class assignments. Great comments! Keep up the good work!

Chawarat Rotejanaprasert replied to the topic How to save file on section 2.2 in the forum Week 2 QGIS 2 years, 10 months ago
Hello, the assignment is aimed to display the number of cases or incidence. However it is ok if you already did morbidity. The point is for you to know how to display epidemiological data on map.

Thank you both. You can pick any clay earthy tone. Nonetheless, the color coding on that one wasn’t clear indeed. No worries about the issue with grading. I understand what you tried to do!

Chawarat Rotejanaprasert replied to the topic Confusion in assignment 1.1 in the forum Week 1 QGIS 2 years, 10 months ago
Hello, the figure on page 27 is an example of the map you could get before changing the symbology. However I can see confusion in the outline color of West_boundary. The default was red for the version we used and so was the screenshot captured. However you can use black or red for the outline color of West_boundary. No worries, you won’t be…[Read more]

QGIS can also run on Mac or Linux, and you are welcome to use them; however, only Windows instructions are given in these lesson materials. If you get hung up and ain’t so familiar with the systems, you may be expected to spend sometime troubleshooting or default to a Windows machine in order to complete the exercises. I’m not a Mac/Linux expert…[Read more]

Hello class… Location or place can be considered as a surrogate for the health outcome of interest.

Hi Tullaya, nice graphics on your presentation. In your discussion, you mentioned that the areas previously affected by other related viruses, eg ZIKV or CHIKV, are susceptible for DENV infection. Can you give epidemiological/clinical evidence or explanations to support this point?
