I'd like my iPhone app to respond to the device owner with his/her Australian LGA (local government area) name using their lat/long.
I've found this page below with a Shapefile:
However, on my Windows server I only have MS-SQL and my programmer's preferred language is c#.
Can anyone possibly help with this?
My programmer is having some issues with this task and I am pasting his email below as someone may spot what the issue could be:
Bad News - SharpMap does not implements features we need (Within, Contains e.t.c.) for polygons our map contains. So, I could not write app logic we planned.
Good News - SharpMap loads SHP file more correct then my previous custom application and therefore there is no errors as I see after loading.
To keep moving forward I have found the next way: I fill each separate region using different color. In our case we have more than 500 regions. So, I shift B part in RGB color from 1 to 255, then G part, and then R part after all. So, I will have map like this one (in server memory, not displayed to user):
but more bigger size to avoid errors. Then I will re-calculate user coordinates to map pixel values and determine which pixel color is in that place. Using color value I will get region name from the list of regions (gotten from DBF file).
So, looks like we still can solve this task. I will continue today. My next steps are: bigger image, re-calc coordinates, determine color.
