how to plot a object with distance in meters on a map with lat and ... (2024)

I created a polyshape out of the section of the circle I want to plot, I didnt have any issue plotting the shape. The issue im running into is determining distance from the arc to the starting point. In real life that range is 25 meters, when I put range at 25, MATLAB thinks thats in degrees and so it plots a massive shape. Im not sure how to go about plotting this as its in meters and not degrees. Is there a way to convert the units of my geoaxes map to UTM? I assume that would be easier than converting meter length to degree length. Thanks agian.

This function on File Exchange should convert your lat/long coordinates to UTM coordinates.

After discussing with one of our Mapping developers, you have the option to work in meters and then adjust the necessary x- and y-offsets to align with your chosen projected CRS. Subsequently, utilize projinv to convert these to latitude-longitude coordinates for use in geoplot. Finding the appropriate offsets might be straightforward if you begin by using your central point in projfwd, follow up with the desired mathematical adjustments in meters, and finally, transform the results back using projinv. Alternatively, you can pinpoint the location by starting with the initial point and projfwd as previously mentioned, but then choose to depict your survey regions using a mappolyshape or maplineshape. By setting the projcrs, which is used in projfwd, as the ProjectedCRS attribute for the shape object, geoplot will manage the necessary subsequent transformations for the shape object.
