Hi All,
I have this shape file that contains: Lat, Lon, Geometry, BegMP, EndMP, RouteNumber... Using the Lat Lon, I can plot the points as below:
However, I cannot acquire the information related to the line path that connect the neighboring points. The Geometry contains a set of string written as "Line". I suspect there is a way to get the connectivity since I can view the line or in arcgis. The arcgis see these as polyline.
Please suggestions. Thank you.

As it is a shape file..I guess already you have the connectivity in hand. You see the below code..I am plotting data of shape file into lines with different colors for each line.
figure
hold on
S = shaperead('concord_roads.shp') ;
for i = 1:length(S)
plot(S(i).X,S(i).Y,'color',rand(1,3)) ;
end
The same, should be applicable for you.
