Problem getting polygons for NY state?
Afficher commentaires plus anciens
I have an image of a CONUS map I made via geoshow:
ax = usamap('conus');
states = shaperead('usastatelo', 'UseGeoCoords', true,'Selector',...
{@(name) ~any(strcmp(name,{'Alaska','Hawaii'})), 'Name'});
faceColors = makesymbolspec('Polygon',{'INDEX', [1 numel(states)],...
'FaceColor',repmat([114 132 153]/255,numel(states),1)});
gs = geoshow(ax, states, 'DisplayType', 'polygon','SymbolSpec', faceColors);
I am replacing the colors of individual states and exporting these states' vector boundaries so I can make each a "clickable" region on a website (via an image-map). This works fine for almost all the states. For example,
gs = geoshow(ax,'Utah')
x=get(get(gs,'Children'),'Xdata');
y=get(get(gs,'Children'),'Ydata');
If I do plot(x,y) I get a nice image of the outline of Utah. However, for some reason this isn't working for New York. Here x and y are 2-dimension arrays, size = (3,298), and the points are not in a logical order; they criss-cross the state and do not make a nice outline.
Anyone here know why NY state is different, and how to reorder the x and y arrays to make a nice polygon?
Thanks!!!

Can you attach the data?
