[R-sig-Geo] Pycnophylactic Interpolation

[Breno Oliveira]

Hi,

I'm a student of Information Systems in Brazil and a junior software archtect. To my final work on the undergraduate program I'm implementing a software with the Potential model. After calculate the potential values to each point of analysis I would like to be able to create a map to represent the result. The map should looks like this one: https://www.r-bloggers.com/contour-and-density-layers-with-ggmap/. I'm new in R so I have no a big knowhow and a lot of doubts. I would like ask for community's help. My problem is that I have no to many points like the example so the map looks incorrect, actualy I have a few points (x,y and z). I think I must Interpolate these points to get a good result, I would like to use the Pycnophylactic Interpolation avaliable in pycno package.

Here is a example of data I obtain (no interpolation applied):


City    Area    Score   latitudes       longitudes      Potentials
Belo Horizone   330,95  2513451 -19,91663263    -43,93337198    164874,1295
Betim   346     412003  -19,96730327    -44,20119724    82629,32514
Contagem        195,268 648766  -19,91615326    -44,08087722    140851,9626
Sarzedo 61,892  25798   -20,06250329    -44,11504723    79307,30623
Rio Acima       50      90      -20,08830329    -43,79104717    55226,91779


Please let me know if you need any extra information.
Thank you for your patience and cooperation.
