Problem in reading .shp file
显示 更早的评论
Hi,
I have a problem in reading .shp file.
My .shp file contains all the major cities in Australia.
I want to read all the major cities located in the state of Queensland only.
I've tried to write code
shapedir = fullfile (pwd, 'Shapefile');
main_cities = shaperead (fullfile (shapedir, 'MainCities.shp'), 'usegeocoords', true);
But after this, I do not know how to do it.
When I opened the variable in the variable editor, I find a field named 'state', containing the name of different states in each struct.
Can someone help me? thank you

Hi, Raymond
You can perform that by adjusting the selector parameter.
I'll give you sample code :
shapedir = fullfile(pwd,'Shapefile');
main_cities = shaperead(fullfile(shapedir,'MainCities.shp'), ...
'usegeocoords',true,'selector', ...
{@(name) strcmp(name,'Queensland'),'state'});

Then you need to create the 'symbolspec'
Eq :
cities_spec = makesymbolspec('point',{'default','marker','o',...
'markeredgecolor','r',...
'markerfacecolor','b'});
Then form mapviewer, you can set the symbolspec from 'layer' menu.
