Projection of data into map file

Hello,

I am planning to extract hotspots information of a city. I have following input paramaters:

Latitude = (1x316)double in xyz-coordinates

Longitude = (1x316) double in xyz-Coordinates

Besides this, i have a map of that city in .png file format with known Lat,Long coordinates. Now, i need to project my input data of (Latitude, Longitude) along with this map of city.

Any ideas, Suggestions? Thanks!

Hi KSSV,

I tried it but i got only few points of my data in the map. Since my data are of size (1x316, 1x316) Latitude, Longitude points i am expecting to project all those points. The output here looks like this:
