Question

How should GIS data be handled and visualised in Opasnet?

Answer

  • Original GIS data is stored in a PostgreSQL database.
  • Data is accessed by R using the RGDAL package and ?? connection.
  • Data in manipulated in R.
  • Ovariables are converted to SpatialPointsDataFrame objects using ova2spat function.
  • Data is displayed by producing a KML file with ?? package.
    • The KML file is created with MyPointKML function, if pins are shown.
    • The KML file is saved at the R-tools server.
    • Google Maps is used to show the KML file on a web page.

Currently, ova2spat and MyPointKML functions are located in OpasnetUtils/Drafts. Therefore, you need this command:

objects.latest("Op_en6007", code_name = "answer") # OpasnetUtils/Drafts. We need MyPointsKML and ova2spat.

This is the projection that the National Land Survey Finland uses: [1].

#: In function google.point_kml, parameter name is not used for anything! --Jouni (talk) 08:42, 26 December 2013 (EET)

#: What we need is a function that eats SpatialPointDataFrames and gives KML files with the data points in different formats (pins, coloured marks etc. --Jouni (talk) 08:42, 26 December 2013 (EET)
