map

[Anne Denis]

Hello everyone,

I am currently working on making some maps in which I need to create a zoom on a section to be able clearly see the data in the corresponding section. It seems that this is only possible to do so using grmap, and not the spmap which I had been previously using. The issue that I am encountering is that in order to use grmap I must first use spset on my data, and I come upon the error stating:

 spset ID
invalid panel setting
    Type xtset to view panel data settings.

when I try to do so. When I check xtset as stated I get that I have a balanced panel, so I am unclear as to what is causing the problem, especially seeing as I have had no problem whatsoever with the same data using spmap.

For further information I have attached the examples of the two maps which I have created with spmap.

Here is an excerpt of the data I am using (I have removed the sensitive data which I am not allowed to share)

end

Here is the code I used:

spset ID
xtset ID
spset, modify coordsys(latlong, kilometers)

resulting in the following:

 
spset ID
invalid panel setting
    Type xtset to view panel data settings.
r(459);

then:

 xtset ID

Panel variable: ID (balanced)

I have also tried a variety of different ways to spset for example using the following:

spset, modify coordsys(latlong, kilometers)
data not spset
r(459);

I would really appreciate any insight into what may be the issue, I have been trying to get this to work on stata for a week now, and have scoured the documentation for help, but have not come very far (clearly)

Thank you so much!
