I am working on an application of land use regression model for predicting NOx concentration in Brisbane, Australia. In total 31 sits monitoring data has been incorporated. I have the result now.
I am now wondering that how I can apply LUR predicted concentration on a map in GIS.
Any advice and suggestions will be greatly appreciated.
Dear Mahmudur,
if I can understand well you need to interpolate these values to include the whole area...In ArcGIS you can use methods such as spline, idw, etc. in order to interpolate values. You can keep some of measurements...let's say the 30% of the sites and conduct the available methods of interpolation with the rest 70% and use the 30% in order to validate your interpolation.
In your NOx coverage data connected to land uses, combine land uses with similar NOx concentrations if you like or just use a color ramp ranging from Greek (low NOx), yellow for moderate, orange for high and red extreme. GIS can do for you by the NOx value, or you can set groups. So in the final map, perhaps forests are green, rural agricultural yellow

GIS can do for you by the NOx value, or you can set groups. So in the final map, perhaps forests or parks may be green (low NOx), sparce rural development, agricultural, forest, grassland mix yellow, low to moderate density urban orange, and high density and industry red. You use the land use polygons which will be color coded by NOx concentration or NOx group. If there is no correlation between land use and NOx, you need to use something else.
I suppose you have worked out the NOx value for different land uses throuhg which you can establish the correlation between land use classes and the NOx and accordingly you can map them through spatial interpolation or any krigging method. can establish now
