MATLAB: Read a shapefile with name that was provided from sprintf

shapereadsprintf

Hello everybody,

I want to read one shapefile, with shaperead command, that his name will change. I have written this code:

    phase2open = cellstr(get(hObject,'String')) 
    nameofphase2open = phase2open{get(hObject,'Value')}
    shp2open= sprintf('phase%s_RP%d_%s.shp',nameofphase2open,RPname2open,nameofsource2open)
    getshp=shaperead('%s',shp2open,'UseGeoCoords',true)

It understands the name and print it but shaperead failed giving this error: "Error using shaperead>parseInputs (line 546) Expected input number 2, PARAM1, to match one of these strings: 'RecordNumbers', 'BoundingBox', 'Selector', 'Attributes', 'UseGeoCoords"____

Best Answer

    getshp = shaperead(shp2open,'UseGeoCoords',true)

MATLAB: Do I receive errors when I use the code described in the documentation for the SHAPEREAD function in Mapping Toolbox 2.0 (R13SP1+)

The R13SP1+ documentation for the SHAPEREAD function in the Mapping Toolbox contains an error; it should have said 'UseGeoCoords' instead of 'GeoCoords'. The correct command is:

shaperead('concord_roads', 'UseGeoCoords', false)

This was fixed in Release 14 (R14).

MATLAB: How to add plot points in the map

"...how can I add the latitude and longitude of each station on my code"

Since you are using the shaperead argument pair {'UseGeoCoords',true},

data = shaperead('tl_2019_us_county.shp','UseGeoCoords',true, . . .);

data will be a structure array including fields lon and lat. To add additional latitude and longitude coordinates,

S(end+1).Lon = 32.52701484484009; % adds an additional structure to array
S(end).Lat = -111.07177734375;    % adds the lat value to the new structure
% Add any other values to the new structure...

If the goal is to add those coordinates to the map, you can do that without altering the shaperead data.

 geoshow(data);
 hold on
 plot(-111.07177734375, 32.52701484484009,'bo')
